• Air is one of the most critical yet often overlooked factors influencing health. Pure, clean air is essential because about 75% of the body’s elimination occurs through the lungs, making oxygenation vital to well-being. Unfortunately, modern environments—especially large cities and indoor spaces filled with pollutants like smoke and industrial fumes—compromise air quality and contribute to incomplete oxygenation, a major but underappreciated cause of illness. Climate also plays a role in health, with moderate, stable temperatures and low humidity being most favorable. High or low humidity levels, especially when paired with temperature extremes, can negatively affect those with respiratory or arthritic conditions. While high altitudes require physiological adaptation due to reduced oxygen, the body responds by increasing red blood cells and lung capacity. Yet, many people with chronic conditions mistakenly seek healing through climate change alone, often at great expense and disappointment, because they overlook the root causes of disease. Ultimately, it is not external conditions but the practice of sound, natural health habits—rooted in Hygienic principles—that create lasting vitality and resilience, allowing individuals to thrive in any environment.

• Human beings are creatures of habit, quickly adopting new behaviors when conditions allow and stubbornly clinging to old ones, especially those that satisfy cravings or addictions. However, widespread habits—like high protein consumption, alcohol use, smoking, or caffeine dependence—are not evidence of physiological need. Just as drinking wine instead of water or smoking to “calm the nerves” does not prove a need for alcohol or nicotine, most cravings arise from habit, not true bodily requirements. Civilized life complicates natural behaviors, and many habits considered normal are actually harmful and based on conditioning rather than biological necessity. When such habits are disrupted, unpleasant symptoms may arise, leading people to mistakenly believe the body “needs” the harmful substance. From extreme cases like drug addiction to more socially accepted habits like coffee, ice baths, or overeating sweets, these behaviors reflect distorted desires, not health needs. Fortunately, harmful habits can be broken through a shift in environment, mindset, and knowledge of true physiological needs. Natural Hygiene, particularly through fasting, offers a powerful, efficient, and gentle method for eliminating even long-standing unhealthy habits, replacing them with positive, life-enhancing behaviors.

• Dr. William L. Esser discusses the nature of human health and how external factors influence it. He begins by challenging the idea that life is a gradual process of dying, arguing that, under ideal conditions, the body is designed for indefinite, vigorous life. The body’s natural processes are equipped for self-maintenance and regeneration, and diseases only arise due to external factors like poor diet, toxic environments, and emotional stress.
• Esser emphasizes that the body can repair itself, continuously renewing cells throughout the year. However, poor hygiene, toxic lifestyles, and constant physical and emotional strain can deplete the body’s resources, leading to weakening and eventual breakdown. He also criticizes modern medicine’s tendency to intervene with treatments that do not address the root causes of illness, arguing instead for a more natural approach to health focused on proper nutrition, rest, and hygiene.

• Natural Hygiene is more than just a fad or dietary trend; it is a comprehensive philosophy aimed at achieving optimal health, happiness, and harmony with oneself and the natural world. It teaches individuals how to live in alignment with nature’s design, focusing on proper diet, breathing, exercise, rest, and mental well-being. Natural Hygiene encourages humans to return to a state of balance and health, similar to how animals and plants live instinctively in harmony with their environment.
• Human beings, endowed with free will, have strayed from their natural state, leading to confusion, moral degeneration, and poor health. The practice of Natural Hygiene helps individuals correct unhealthy physical habits and, through this process, develop a moral awareness that aligns with the Creator’s intentions. It suggests that physical health and moral integrity are closely intertwined: a person who indulges in harmful habits like overeating, drinking, or drug use suffers both physically and morally. These imbalances can lead to personal and societal harm, as unhealthy individuals may make poor decisions that negatively impact others.
• Natural Hygiene emphasizes that human health cannot be fully restored without addressing both the physical and moral aspects of life. Overindulgence, whether in food, drink, or other behaviors, not only damages the body but also weakens moral judgment and societal harmony. By restoring health through natural practices, individuals can contribute to the well-being of society as a whole.

https://www.healthscience.org/wp-content/uploads/2023/03/Volume-1-N5-Natural-Hygiene.pdf

• In The Climb to the Shelf, Dr. William Esser discusses the premature physical decline that many people, particularly athletes, experience between the ages of 40 and 60. He highlights how some athletes, despite their experience, struggle to maintain peak performance due to neglecting their health, as seen in the cases of figures like Babe Ruth. He also reflects on the tragedy of untimely deaths of prominent individuals and argues that life expectancy improvements have mainly affected children, not adults, due to better hygiene, sanitation, and nutrition.
• Dr. Esser criticizes the modern lifestyle, which is increasingly marked by unhealthy habits leading to premature aging, illness, and death. He calls out society’s false belief that people are living longer and healthier lives, warning that adults’ self-destructive habits are contributing to an overall decline in life quality, and the average life span may actually be decreasing.

https://www.healthscience.org/wp-content/uploads/2023/03/Volume-1-N6-7-Natural-Hygiene.pdf

• In Tropical and Sub-Tropical Fruits, Dr. William Esser explores the nutritional benefits and variety of tropical and sub-tropical fruits, which are often underappreciated in non-tropical regions. These fruits are rich in vitamins, minerals, and healthy fats and can offer a diverse and flavorful addition to any natural diet. While common tropical fruits like bananas, citrus, and pineapple are well-known, many others are less familiar to the average consumer.
• Key fruits discussed include: Avocado, Barbados Cherry, Canistel, Cactus Fruit, Cherimoya, Guava, Litchi, Mango, Papaya, Sapodilla, and Sugar Apple.

https://www.healthscience.org/wp-content/uploads/2023/03/Volume-1-N6-7-Natural-Hygiene.pdf

• Dr. Esser discusses the causes, implications, and management of abortion, miscarriage, and premature delivery, defining each based on the stage of pregnancy. An abortion occurs from conception to the fourth month, a miscarriage from the fourth to the sixth month, and premature delivery after the sixth month.
• He suggests that the modern rate of abortions is much higher than statistics show, mainly because many induced abortions go unreported. He also identifies poisons (such as alcohol, lead, and coal gas) and emmenagogues (substances that induce menstrual flow) as common causes of accidental or intentional abortion.
• Esser emphasizes that general physical debility, poor eating habits, overwork, lack of rest, and emotional strain are primary contributors to pregnancy loss. He criticizes the overprotectiveness and idleness imposed on pregnant women by societal expectations, which often lead to mental exhaustion and physical debility, both of which hinder a healthy pregnancy. He advocates for regular exercise, such as walking, swimming, or light calisthenics, to maintain physical health during pregnancy.

https://www.healthscience.org/wp-content/uploads/2023/03/Volume-1-N10-11-Natural-Hygiene.pdf

• Dr. William Esser challenges the widespread belief that illness is an unavoidable part of life. He argues that society has been conditioned to accept disease and death as inevitable due to fear instilled by various professions, including clergy, medicine, and law. This fear has weakened people’s health and resistance, especially in countries like America, where seeking cures and treatments has become a popular yet misguided pursuit. According to Dr. Esser, the real issue lies in people’s unhealthy habits and their failure to understand how to live in harmony with the natural laws of life.
• Dr. Esser critiques the past fears surrounding germs and viruses, suggesting that illness is not caused by external invaders like germs, but by individuals’ own violations of natural laws, such as poor habits and lack of self-control. He emphasizes that the true enemies of mankind are the habits and choices that lead to disease, rather than some external force like bacteria or viruses. Once people stop making themselves sick, they can become immune to illness, as disease no longer exists in a healthy, self-aware individual.

Esser, W. L. (1955, July). “Is Illness Inevitable?” Health Science (reissued 2022).
https://www.healthscience.org/wp-content/uploads/2022/07/Summer-2022-Timeless-Teachingpdf.pdf

• In “Is Illness Inevitable?” by W.L. Esser, originally published on July 1, 1955, and reissued in 2022, the author challenges the widespread belief that illness is an unavoidable part of life. Esser argues that rather than being an inevitable fate, illness is primarily the result of factors such as poor lifestyle choices, neglect of personal health, and a lack of preventative measures. He asserts that individuals have the power to prevent or significantly reduce their risk of illness through conscious, proactive health practices.
• Esser highlights the role of nutrition, exercise, mental well-being, and emotional balance in maintaining overall health. He stresses that a proper diet, regular physical activity, and positive mental habits are essential for building a robust immune system and preventing disease. Additionally, Esser critiques the tendency to rely on medical interventions only after an illness has occurred rather than focusing on prevention and lifestyle changes that could minimize the likelihood of becoming sick in the first place.
• The article also touches on the importance of self-responsibility in health. Esser encourages readers to take charge of their well-being by being mindful of their daily life choices and adopting habits that support long-term health. He emphasizes that illness is not an unavoidable consequence of aging or genetics but something that can be managed, prevented, or even reversed through intentional, informed actions.
• Reissued in 2022, the article’s message remains relevant as modern society faces widespread health challenges such as chronic diseases, mental health struggles, and lifestyle-related illnesses. Esser’s optimistic view—that illness is not inevitable and can often be prevented—is an empowering reminder for readers to take control of their health through mindful living and personal responsibility.

https://www.healthscience.org/wp-content/uploads/2023/03/Volume-1-N12-Natural-Hygiene.pdf

• Dr. William Esser critiques the use of alcohol, describing it as a harmful habit that only appears pleasurable but ultimately damages the body and mind. He acknowledges that while people may find temporary satisfaction in alcohol, its long-term effects are destructive. Alcohol is not a food or a stimulant, as it impairs physical coordination, mental faculties, and judgment. It can create the illusion of strength or warmth, but in reality, it reduces the body’s energy, control, and endurance.
• However, he believes in the potential for recovery through Hygienic treatment, which involves using natural remedies such as sunlight, rest, fresh air, exercise, and a wholesome diet. Alcoholism is viewed as a disease, requiring a holistic approach to rebuilding physical and mental health.

https://www.healthscience.org/wp-content/uploads/2023/03/CONVENTION-1956.-Los-Angeles-CA.pdf

• This article emphasizes the importance of living a balanced, health-conscious life rooted in the principles of Natural Hygiene. It critiques modern society’s obsession with speed, stimulation, and external performance—likening high-speed cars and high-octane fuels to the artificial stimulants people use to keep up with demanding lifestyles. Coffee, tea, cigarettes, drugs, and emotional excesses are all forms of unnatural stimulation that overwork the body’s glands and deplete its reserves, leading to physical and mental breakdown. Rather than addressing illness by removing its causes, people often seek external aids—pills, hormones, injections—that mask symptoms but further harm the body. This cycle leads to early aging, chronic disease, and diminished vitality. Esser urges a return to natural living: conserving energy, controlling emotions, avoiding unnecessary stimulation, and maintaining harmony with the body’s needs. True health and fulfillment come not from frantic activity or chasing youth, but from intelligent self-regulation and respect for one’s biological limits. Even successful businessmen who lived long, healthy lives credited moderation, optimism, and simplicity—core tenets of Natural Hygiene—for their well-being. Ultimately, the message is clear: slow down, live wisely, and choose health over hustle.

• Asthma is a debilitating condition that often arises due to poor lifestyle choices, but it can be fully eliminated in about 95% of cases with proper treatment. Dr. William Esser describes a case of a woman suffering from severe asthma for over ten years, relying on increasingly potent medications like ephedrine, cortisone, and ACTH, without understanding the root cause of her illness. Her symptoms included chronic congestion, wheezing, indigestion, constipation, and dangerously high blood pressure. Despite her dependency on medication, the patient agreed to undergo a 25-day fast with only distilled water as part of a Natural Hygiene program.
• Dr. Esser explains that asthma is often caused by a combination of factors like overeating, particularly high-protein and carbohydrate foods, lack of sleep, overexertion, tobacco use, sexual exhaustion, and negative emotions. While traditional medicine emphasizes allergies as a cause, Natural Hygiene views asthma as a result of nerve exhaustion and accumulated toxins. Asthma sufferers must adopt moderation in all aspects of life, including eating, work, sex, and emotions. Cultivating self-control and poise is essential for long-term recovery and preventing relapse. Ultimately, maintaining good health through balance and self-discipline is the key to overcoming asthma.

• The press and medical journals often celebrate the rising average life span, aiming to push it to 150 years or more. However, the real credit for improved longevity belongs not to modern medicine, but to the early pioneers of Natural Hygiene, whose reforms brought about significant improvements in lifestyle—better clothing, housing, sanitation, fresh air, sunshine, and natural foods. These changes laid the foundation for the healthier lives many now enjoy. Without them, the world would face even worse disease conditions than centuries ago, compounded by the harmful interventions of modern medicine and artificial living. Today, Natural Hygiene has an even greater role to play in guiding society toward true health, particularly as personal freedoms face increasing threats. Mandatory vaccinations like the Salk vaccine, and potentially others, represent a dangerous infringement on individual rights. Such medical coercion is more invasive than forcing someone to adopt unwanted political or religious beliefs, as it involves the irreversible introduction of harmful substances into the body. Natural Hygiene stands as a vibrant and growing movement, deserving of care and protection. To ensure its continued influence, the Society must expand and unite into a strong force capable of defending health freedom. Many people desire the right to choose their own path to health but lack the voice to make it heard—Natural Hygienists must be that voice.

https://www.healthscience.org/wp-content/uploads/2023/03/NH-May-1957.pdf

Summary of Esser’s Answers by Dr. William Esser:

• Best Foods for Pregnancy: Dr. Esser recommends a diet of fresh, ripe fruits, green leafy vegetables, and raw nuts (e.g., almonds, pecans, cashews) for women aiming for a healthy pregnancy. He advocates a predominantly raw food diet, with exceptions like baked potatoes, squash, and whole rice. Processed, denatured foods, as well as salt, pepper, condiments, and flesh foods, should be avoided. Additionally, he stresses the importance of hygiene, exercise, rest, sunshine, fresh air, and emotional balance for both the mother and child.
• Breaking Wrong Eating Habits: Esser suggests that fasting is the most effective method to break bad eating habits. Fasting helps regenerate the senses, particularly taste, allowing individuals to appreciate natural, wholesome foods more. He supports the use of self-advice (auto-suggestion) but rejects hypnosis as a method for changing eating habits.
• Natural Hygiene and Cancer: Dr. Esser believes that following natural hygiene practices can prolong the life of cancer patients and improve their comfort. He opposes surgery, as it may stimulate metastasis and is rarely beneficial.
• Poison Resistance in Life Forms: While some life forms may adapt or “adjust” to poisons like insect sprays, Esser argues that this tolerance does not eliminate the harmful effects of toxins, which always remain detrimental to health.
• Thyroid Removal in a 30-Year-Old: After thyroid removal, Esser emphasizes the importance of following healthy habits and eating natural foods (especially raw green salads) for continued health. A small part of the thyroid is essential for metabolic balance, and with proper care, the individual can live a healthy life.
• Polio Prevention and Fasting: Esser advocates for a holistic approach to polio prevention, including proper use of sunshine, exercise, rest, clean air, and a natural diet. During the acute phase of polio, he recommends bed rest, water fasting, and maintaining a positive attitude. After recovery, hygienic conditions and regular exercise can help with rehabilitation, although some muscle and nerve impairments may persist.

Summary: Dr. William Esser’s Answers (Feb. 1958)

• Psychology, Psychiatry, and Psychoanalysis in Health
  Dr. Esser believes practical psychology can contribute to mental health, but psychiatry and psychoanalysis often lead to confusion for the mentally disturbed. He emphasizes that any approach ignoring the connection between mental and physical health is unlikely to be successful.
• Natural Sex-Hygiene
  “Natural sex-hygiene” refers to using sex primarily for procreation. Dr. Esser acknowledges that this is not the norm in modern society, where distorted values and excessive indulgence in sensory pleasures dominate, including food, drink, and sex. He supports a natural approach to living based on the body’s physiological needs, urging individuals to choose between indulgence and health consciously.
• Vitamins in Pill Form
  Dr. Esser argues that natural foods provide all the necessary vitamins for good health, making vitamin pills unnecessary. He suggests that spending money on nutritious foods is more beneficial than on expensive supplements that may be ineffective or harmful.
• Restoring Gray Hair to Its Natural Color
  Dr. Esser reports that, in a few cases, individuals who improved their living habits were able to restore their gray hair to its natural color. However, such occurrences are rare.

• Dr. William Esser argues that illness is not an inevitable part of life but rather a result of man’s own actions, habits, and ignorance. He critiques society’s fear-driven approach to health, which is influenced by various professions—such as religion, medicine, and law—that promote the idea of disease as an unavoidable fate. This fear-based mindset diminishes vitality, reduces health standards, and leads to unnecessary suffering.
• Esser points out that many people have been conditioned to believe in the inevitability of illness, and society often turns to external solutions, like drugs or surgical interventions, which only treat symptoms rather than address the root causes. However, he stresses that illness is ultimately self-inflicted through improper lifestyle choices, poor self-awareness, and failure to live by natural laws. When individuals stop making themselves sick by adhering to healthy habits, they can become immune to disease.
• He also highlights the role of modern society in exacerbating these problems, noting that the fast-paced, stress-filled life and reliance on artificial stimulants like coffee and tobacco have led to an overtaxed nervous system, digestive issues, and premature aging. People often fail to maintain their health and longevity because they neglect the simple, natural principles of self-care in favor of modern, unhealthy habits.
• Dr. Esser advocates for a return to natural hygiene—living in harmony with nature’s laws through common-sense practices such as moderation, proper rest, and mindful living. He rejects the idea of relying on external treatments or complex, synthetic solutions to health. Instead, he encourages individuals to become self-aware and take responsibility for their health by understanding the true causes of illness and focusing on self-care.

• Reprinted from the book Dictionary of Foods, with permission of the author.
• The text discusses that maintaining a healthy diet of natural foods doesn’t have to be prohibitively expensive, and can reduce living costs. It suggests that rural dwellers can benefit from growing their own food, while urban residents can access a wider variety of fresh produce. The author emphasizes that consuming out-of-season and imported foods not only costs more but may also be of lower quality. Additionally, it critiques spending on processed and unhealthy foods, arguing that investing in wholesome foods is an investment in health. The text highlights the importance of good nutrition for children’s development and suggests that even poor people can improve their diet by choosing whole, natural foods. Ultimately, better nutrition is linked to greater efficiency, improved health, and potentially higher earnings.

https://www.healthscience.org/wp-content/uploads/2022/07/Summer-2022-Timeless-Teachingpdf.pdf

• In the article “Illness Is Not Inevitable” by W.L. Esser, initially published in Health Science in 1958 and reissued in 2021, the author challenges the conventional view of illness as an unavoidable aspect of life. Esser argues that illness is not a predetermined or inevitable part of the human experience but rather the result of various factors, including lifestyle choices, environmental influences, and the body’s ability to maintain balance. He emphasizes the importance of taking responsibility for one’s own health through proper nutrition, exercise, and mental well-being.
• Esser advocates for a proactive approach to health, suggesting that with the proper knowledge and habits, individuals can significantly reduce their risk of illness and even prevent it altogether. The article critiques the prevailing medical paradigm of the time, which often viewed disease as an external force to be treated only once it appeared. Instead, Esser promotes a more holistic and preventive approach, urging readers to cultivate habits that support long-term health and vitality.
• The reissue in 2021 highlights the enduring relevance of Esser’s message in today’s context, as modern health challenges such as chronic diseases, stress, and environmental factors continue to affect global populations. His call for a shift in perspective—from viewing illness as inevitable to seeing it as preventable—is presented as both timely and empowering.

Esser, W. L. (1959, Jan). “The Time for Personal Appraisal”. Health Science (reissued Jan 5, 2022).
https://www.healthscience.org/wp-content/uploads/2022/01/Spring-2021-Timeless-Teachings.pdf

• In “The Time for Personal Appraisal” by W.L. Esser, initially published in Health Science on January 5, 1959, and reissued in 2022, the author calls for individuals to regularly assess their lives to improve their health and well-being. Esser suggests that personal appraisal—an honest, reflective look at one’s habits, mindset, and choices—is essential for long-term health and personal growth.
• Esser argues that people often live on autopilot, neglecting to evaluate whether their behaviors and attitudes serve their best interests. He emphasizes that true health and happiness come from understanding one’s needs, strengths, weaknesses, and the factors that influence personal health. By conducting regular self-assessments, individuals can identify areas that may require change or improvement, such as unhealthy habits, negative thought patterns, or imbalances in work, relationships, and lifestyle.
• The article highlights the importance of self-discipline and the willingness to take responsibility for one’s health. Esser also encourages readers to adopt a proactive approach to life, making conscious decisions to improve their physical, emotional, and mental well-being. This process of personal appraisal, he believes, is crucial in preventing illness and enhancing quality of life.
• Esser’s message in this article is timeless, offering readers practical advice on cultivating greater self-awareness and making informed choices that promote health and happiness. His emphasis on introspection, responsibility, and personal growth is as relevant today as in 1959, especially when many people face stress, chronic health conditions, and lifestyle-related challenges.

• Fruits are presented as the ideal food, enchanting the senses and requiring no preparation or seasoning, making them wholesome and perfect for the diet. Nuts, although often overlooked, are also considered nutritionally superior and should play a larger role in meals, while vegetables contribute essential vitamins and minerals. The text emphasizes the importance of including large salads of raw vegetables in daily meals, alongside fruits and nuts, to achieve optimal nutrition. Suggested menus for a week include a variety of fruits for breakfast and lunch, and vegetable salads for dinner, aiming for a balanced intake of these food groups.

https://www.healthscience.org/wp-content/uploads/2023/03/NH-June-1959.pdf

• The text discusses the inevitability of aging and the physical declines accompanying it, emphasizing the importance of maintaining personal health throughout life rather than only addressing issues when they become severe. It critiques societal tendencies to accept deteriorating health as a natural part of aging and warns against neglecting hygiene and well-being, suggesting that true vitality requires adherence to natural laws of health. The author highlights that many people lead lives that prioritize short-term pleasures over long-term wellness, resulting in a metaphorical “death” before actual physical demise, as they become disconnected from activities that promote genuine enthusiasm for life. This reflection serves as a call to examine personal health habits and make meaningful changes, particularly in the context of a health-focused gathering.

https://www.healthscience.org/wp-content/uploads/2023/03/NH-Feb.-1960.pdf

• Caring for a baby is a significant challenge that requires understanding the long-term impacts of child-rearing practices on a child’s physical, mental, and moral development. While heredity plays a role, the prenatal and postnatal nurturing provided by parents is even more crucial. Overindulgence or neglect can lead to detrimental outcomes, and responsible parenthood entails personal reform and education to foster a healthy environment for the child. Essential practices include adopting a hygienic lifestyle with a focus on nutrition—favoring raw and fresh foods—regular exercise, and adequate rest. Establishing healthy habits early in a child’s life is vital for their overall well-being and future success, ensuring they grow up free from harmful influences and equipped for happiness and longevity.

https://www.healthscience.org/wp-content/uploads/2023/03/NH-June-1960.pdf

• Natural Hygiene, as outlined by William L. Esser, emphasizes the critical link between health and happiness, asserting that true well-being is foundational for a meaningful life. The human body, a complex and perfectly designed organism, requires specific conditions—such as clean air, proper nutrition, adequate rest, and exercise—to maintain optimal health. Despite humanity’s adaptability to various environments, achieving the best physical, mental, and spiritual development relies on understanding and adhering to these natural health principles. Esser highlights the detrimental effects of modern pollutants and lifestyle choices on health, advocating for fresh air and rest over quick fixes like stimulants, to foster genuine vitality and restore the body’s innate balance.

Esser, W. (1961, July). Convention Time – A Time for Personal Inventory. 1961 ANHS Convention Program, pp. 6- 7. 
https://www.healthscience.org/magazine/conference-program-chicago-1961/

• This article reflects on the rapid passage of time and the physical and emotional decline that often accompany aging due to poor lifestyle choices. Many people only realize the toll of unhealthy living—wrinkles, fatigue, digestive issues, chronic pain, and disease—once the damage is already done. Often, these symptoms are dismissed as “normal aging,” tolerated, or ignored until serious illness forces attention.
• The author criticizes modern living for its chaotic, indulgent habits—overeating, smoking, drinking, overworking, medicating, and chasing false pleasures—arguing that these behaviors lead to slow, painful deterioration rather than genuine freedom or vitality. The idea of “living life to the fullest” is questioned, as many who live this way merely accelerate their decline and spend years suffering.
• The passage champions Natural Hygiene—a lifestyle rooted in natural laws and healthful living—as the key to preserving true vitality and avoiding needless suffering. It warns that rejecting these principles is akin to breaking the laws of nature, which inevitably leads to consequences, just like ignoring traffic laws leads to disaster.
• Finally, Esser urges readers, especially those attending a Hygienic convention, to seriously evaluate their lives and make lasting changes—not as a sacrifice, but as a liberation from destructive habits. Those who embrace the Hygienic lifestyle belong to a privileged few with the knowledge and opportunity to reclaim health, happiness, and purpose before it’s too late.

Esser, W. (1962, July). What is Your Index of Success? 1962 ANHS Convention Program, pp 9.
https://www.healthscience.org/wp-content/uploads/2023/03/CONVENTION-1962.-Miami-Beach-FL.pdf

• People often equate success with wealth, status, or achievement in their chosen field, believing these will bring happiness. However, true success and fulfillment are impossible without health. This becomes clear when individuals, regardless of their wealth or accomplishments, are faced with serious illness. In such moments, all material success becomes meaningless compared to the desire to regain health.
• Natural Hygienists witness this firsthand, seeing people from all walks of life desperate to feel well again—leaving behind careers, possessions, and family obligations in search of healing. Health is the foundation of all joy and purpose in life, allowing one to fully experience and appreciate living.
• Natural Hygiene teaches that health is not a matter of luck or genetics, but the result of understanding and living in harmony with natural laws—through proper food, rest, exercise, and emotional balance. It requires discipline, consistent practice, and self-care. Merely knowing the rules of health is not enough; they must be applied.
• When health is prioritized and nurtured, it becomes evident—not just in physical strength and vitality, but in a slower aging process and a life free from chronic illness. Real success lies in mastering the habits that sustain well-being. This form of success opens the door to a richer, longer, and more joyful life.

https://www.healthscience.org/wp-content/uploads/2021/09/HealthScience_TimelessTeachings_Spring2016.pdf

• In “The Time for Decision” by W.L. Esser, originally published on March 1, 1963, and reissued in 2021, the author explores the concept of personal decision-making and its impact on health and well-being. Esser argues that the key to achieving and maintaining good health lies in individuals’ conscious decisions about how they live their lives. He emphasizes that health is not merely the result of external factors, such as genetics or fate, but is primarily shaped by the choices we make every day regarding nutrition, exercise, stress management, and mental outlook.
• Esser stresses that the time to make these decisions is now—there is no better moment than the present to take charge of one’s health. He notes that procrastination or indecision often leads to adverse health outcomes, as people delay making the necessary lifestyle changes to prevent illness or improve their overall quality of life. Instead of waiting for a health crisis to prompt action, Esser advocates for taking proactive steps toward better health today.
• The article emphasizes the power of personal responsibility. Esser encourages readers to make thoughtful, intentional choices regarding their diet, physical activity, and mental well-being, recognizing that these choices will directly influence their future health. Deciding to adopt healthy habits, such as proper nutrition, regular exercise, and positive thinking, is an essential part of preventing disease and promoting long-term vitality.
• Reissued in 2021, the article’s message resonates as it calls on individuals to prioritize their health and make empowered decisions that support a balanced, fulfilling life. Esser’s emphasis on taking immediate, personal responsibility for one’s health is a timeless reminder of the importance of decision-making in shaping our physical and mental well-being.

• The article “The Dangerous Years” by W.L. Esser, initially published in 1964 and reissued in 2021 by Health Science, explores the risks and challenges associated with adolescence and early adulthood, mainly focusing on the behaviors and decisions that can have lasting consequences on an individual’s health and well-being. Esser uses the term “dangerous years” to describe the period of life when individuals are most vulnerable to risky behaviors, including experimentation with substances, unprotected sexual activity, and other forms of self-destructive behavior.
• Esser emphasizes the importance of education, guidance, and prevention during these formative years to help steer young people toward healthier choices. The article underscores the role of parents, educators, and healthcare professionals in providing support, advice, and resources to help adolescents navigate the pressures and temptations of youth. The piece reflects the cultural and societal concerns of the time, particularly regarding public health and the need for proactive interventions to safeguard the younger generation’s future.
• Although written in the mid-20th century, the article’s themes around health education, prevention, and adolescent development remain relevant today. The reissue of the article serves as a reminder of the importance of addressing the risks young people face during their most vulnerable years and the long-term impact of positive guidance.

• This article emphasizes that the body constantly sends warning signals—such as colds, fevers, skin eruptions, digestive issues, and emotional imbalances—when its needs are not being met. These symptoms, often beginning in infancy and intensifying with age, indicate the violation of natural laws regarding diet, rest, exercise, and emotional well-being. While the human body possesses a remarkable ability to adapt and recover, this resilience diminishes over time, especially after the age of forty, when cumulative physiological abuse often leads to serious, chronic illnesses. Despite its built-in safety margins, the body cannot indefinitely endure repeated abuses, such as overeating, smoking, and poor lifestyle habits. As aging progresses, recovery slows, symptoms become persistent, and vital systems begin to fail, leading to dependency and suffering in later years. The passage argues that such outcomes are largely preventable through adherence to Natural Hygiene principles, which promote a return to simple, health-supporting habits. Though most people desire health, few take deliberate steps to preserve it. The author warns that ignoring the body’s signals can result in irreversible damage, while following a hygienic lifestyle can ensure a healthier, more independent, and fulfilling life.

• Adopting Natural Hygiene can be a deeply transformative but socially challenging journey. Newcomers often begin with uncertainty, then grow enthusiastic as their health improves without drugs—relying solely on nature’s healing power. This excitement can sometimes lead to awkward social situations, especially when their appearance during recovery (like after prolonged fasting) and fervent explanations of their lifestyle seem extreme or incomprehensible to others. Despite public skepticism or ridicule, their passion is fueled by real healing—such as relief from chronic pain, tumors, or debilitating illness—often after exhausting traditional treatments. These powerful personal victories naturally inspire a desire to share the message widely. However, since most healthy people are resistant to lifestyles that demand discipline, Natural Hygiene is often embraced only when health fails. For those who find new life through it, public opinion matters little—but they are encouraged to be patient and understanding, remembering they too once lacked the knowledge they now cherish.

• Sex is one of humanity’s strongest natural drives, rooted in the biological imperative to reproduce and governed by natural laws deserving of respect. Historically, society has often treated the topic of sex with shame or silence, but Natural Hygiene has consistently advocated for an informed, respectful, and disciplined understanding of all bodily functions, including sexuality. Early Hygienists promoted education to dispel ignorance and encourage healthy living. However, in modern society, sexual expression has become increasingly undisciplined, with widespread promotion of promiscuity, perversion, and pornography, often glorified by the media and even endorsed by some professionals. These shifts have led to moral and physical decline, replacing restraint and reverence with exploitation and indulgence. Physiological laws have not changed over time, and excess in sexual activity—as in all other bodily functions—inevitably leads to health deterioration. Unchecked sexual preoccupation can cause congestion in the sexual organs and contribute to diseases. Attempts to address the resulting dysfunction through drugs, hormones, or therapy fail if underlying causes are ignored. Natural Hygiene emphasizes moderation, self-awareness, and proper body care as the foundation for maintaining lasting sexual vitality. It rejects artificial contraception and promotes abstinence or natural methods when necessary. Ultimately, when practiced within the bounds of health, respect, and responsibility, sex can elevate rather than degrade the human experience.

• Undisciplined emotions, especially fear, are among the most wasteful and destructive uses of human energy, depleting nerve force without any constructive outcome and causing real physiological harm. While normal emotional expression—such as joy, sadness, or love—is essential to a healthy life, chronic negative emotions like worry, resentment, and fear undermine emotional balance and lead to disease. Fear, in particular, is both a cause and result of illness, forming a vicious cycle that damages digestion, glandular function, and the nervous system. Even minor fears, when accumulated over time, can paralyze the body’s normal processes and lower resistance, creating fertile ground for disease. Many people live under constant fear—of health, relationships, finances, or daily life uncertainties—further draining their vitality. Often, these fears are irrational or imaginary, and their power stems from ignorance about the body’s ability to heal under proper conditions. Disease fosters fear, and fear in turn worsens disease. The Natural Hygiene approach offers a solution by promoting physical and mental health through clean living, rest, fasting, and understanding the body’s innate healing capabilities. When health is restored, fear diminishes, and in its place, emotions like joy, contentment, and confidence take root, promoting further wellness. Ultimately, fear serves a limited, protective function but should not dominate the mind or body. Restoring and maintaining good health is the most effective path to emotional stability and a fearless life.
• As Dr. John Tilden suggested, people must choose whether they want to be “poised or poisoned”—a choice between calm self-awareness or the toxic effects of fear and worry.

• Becoming acquainted with Natural Hygiene is described as one of the most profound events in a person’s life, despite its seemingly unexciting name. While modern culture is often captivated by artificial stimulation and superficial entertainment, Natural Hygiene represents a deep and vital body of knowledge that is often overlooked. Its principles, rooted in the observation of natural laws and human biology, offer a clear, practical guide for achieving and maintaining health. Pioneers like Isaac Jennings, Sylvester Graham, and others laid the foundation for this life science over a century ago, recognizing that disease is largely the result of human behaviors that violate nature’s laws—not mysterious forces or medical deficiencies. Recovery, they found, often happens not because of treatment, but in spite of it. These early Hygienists created an enduring philosophy and system of health—based on diet, rest, air, sunlight, and emotional balance—that rejects the mainstream focus on drug-based cures. The current American Natural Hygiene Society, reestablished in 1949, carries forward this mission and stands as a leading voice for true health education and the protection of individual medical freedom, which is increasingly under threat. The Society views its work as essential in a world where interventions like forced inoculations and environmental toxins infringe on personal health rights. Members are encouraged to recognize the Society’s critical role, support it through action, membership, and financial contributions, and help ensure its growth. In doing so, they contribute to a movement that not only preserves health knowledge but defends the fundamental right of individuals to live in harmony with nature, free from the dominance of commercial medicine.

Esser, W. (1969, July). Does Education Educate? 1969 ANHS Convention Program, pp. 23-25.
https://www.healthscience.org/magazine/conference-program-new-york-1969

• While humanity has made remarkable advancements in science, technology, and exploration, this progress has often led to misplaced trust in science to meet all of our needs—including health. Modern medicine, masquerading as science, has failed to educate people on the true laws of life and has instead focused on drug and serum therapies that suppress symptoms while ignoring root causes. The medical establishment, notably the AMA, has neglected its responsibility to inform the public about major health dangers like pollution, pesticides, tobacco, and toxic chemicals, often due to profit motives and institutional inertia. Historically, it has been independent health reformers—such as Graham, Jennings, Tilden, and Shelton—who have courageously exposed these dangers and educated the public, often facing ridicule and accusations of quackery. In this tradition, the American Natural Hygiene Society was founded to foster a genuine health revolution rooted in physiological truth and environmental awareness. The Society has grown steadily over the past two decades, and its members are called not only to live healthfully but also to share their knowledge and actively oppose harmful practices such as forced immunizations, food chemicalization, and environmental degradation. The survival of humanity and the health of future generations depend on a collective, urgent effort to restore balance and uphold the natural laws of life.

Esser, W. L. (1972). Dictionary of Man’s Foods (1972nd ed.). A Natural Hygiene Book.
https://www.amazon.com/Dictionary-mans-foods-natural-hygiene/dp/B0006WT1Q6

“Dictionary of Man’s Foods” by William L. Esser was first published in 1972 and republished in 1983. This book is known for its focus on natural hygiene. It offers information about a wide range of foods, particularly regarding their nutritional and health benefits, according to the principles of natural hygiene.

Included in  the Book:

1. Natural Hygiene Philosophy: Esser’s book aligns with the natural hygiene movement, which advocates for eating foods in their most natural, unprocessed form to promote health and longevity. This philosophy discourages the consumption of cooked, processed, and refined foods, recommending raw, organic produce and simple preparations instead.
2. Food Classification: The dictionary-style format organizes foods by their types (e.g., fruits, vegetables, grains, nuts, seeds, etc.) and describes their nutritional benefits. Foods are often assessed for suitability in a natural hygiene diet, emphasizing simplicity and ease of digestion.
3. Food Benefits and Health: For each food, Esser typically outlines:
   • Nutritional Content: Key vitamins, minerals, and other beneficial compounds in the food.
   • Digestibility: How easily the body can process and absorb the food.
   • Health Implications: Potential health benefits, such as promoting detoxification, aiding digestion, or boosting immunity.
   • Cautionary Notes: Any foods that might be harmful if consumed improperly or in excess, such as those that are overly acidic or difficult to digest.
4. Food Pairing and Combinations: The book often delves into how different foods interact regarding digestion and overall health. Natural hygiene advocates that certain food combinations may improve digestion while others may lead to discomfort or health problems.
5. Holistic Approach: Esser, like other natural hygiene proponents, takes a holistic view of nutrition, where food choices are seen as part of an overall lifestyle that includes physical activity, rest, and mental well-being. The goal is to promote a balance between body, mind, and the food you eat.

• In his article “Immutable Dietary Law,” William L. Esser, N.D., emphasizes the discrepancy between human dietary practices and our biological nutritional needs, which align closely with those of primates. He argues that, unlike other animals that instinctively choose nourishing foods, humans often eat for pleasure and convenience, deviating from natural laws. Esser critiques the modern food industry for introducing artificial additives, processing techniques, and unhealthy practices that compromise nutritional quality. He references early Hygienists who highlighted the importance of food’s natural form for optimal health and notes that while interest in better eating has grown, much of the contemporary literature is marred by misconceptions. Esser concludes that human nutrition is fundamentally based on unchanging biological needs, advocating for a diet consisting primarily of raw fruits, nuts, and vegetables, which should be consumed in their natural state to ensure proper nourishment.

• The keynote address delivered by Dr. Esser highlights the foundational principles of Natural Hygiene, emphasizing that the human body is self-renewing, self-repairing, and self-maintaining, qualities that have allowed mankind to endure various challenges throughout history. Dr. Esser references Isaac Jennings, a pivotal figure in the Hygienic system, who, after twenty years of conventional medical practice, discovered that patients who received no medication often recovered faster than those who did. This led Jennings to adopt a practice of Natural Hygiene, abandoning traditional medications and instead relying on the body’s inherent healing capabilities, which he documented in three significant works. Additionally, the address mentions Sylvester Graham, known for his influence through educational works and the creation of Graham Houses, further contributing to the spread of hygienic principles. Dr. Esser recounts a personal anecdote about discovering a family connection to Jennings, underscoring the enduring legacy of these early hygienic thinkers and their contributions to health science.

• The concept of a “cure” is challenged by proponents of Natural Hygiene, who argue that true healing comes not from doctors or drugs, but from the body’s own inherent vital force, or viz vitae. According to this philosophy, what many consider cures—medications, treatments, and suppressions—are illusions that mask symptoms rather than eliminate the root causes of disease. Relying on these so-called cures encourages unhealthy living by offering a false sense of security and escape from consequences. Natural Hygienists stress that health must be earned through personal responsibility, self-discipline, and adherence to the laws of nature. Emotional and physical indulgence—such as overeating, substance abuse, or sexual excess—leads to disease, and the only genuine “cure” is to eliminate the harmful behavior causing the condition. Pain and illness are seen as nature’s warnings, not enemies to be silenced. The article emphasizes that ignoring these signals and continuing destructive habits invites inevitable and often severe consequences. True health and longevity depend on understanding and respecting natural laws, not seeking escape through quick fixes. As nature never forgives, the only way to maintain well-being is to live in harmony with its principles.

• Living healthfully in an unhealthy environment is challenging but entirely possible with the right habits and mindset. While it’s true that no one can live completely hygienically in a polluted, high-stress city, one can still achieve a high standard of health through conscious lifestyle choices. Emotional balance is essential—negative emotions like fear, anger, and worry do more harm than poor food or bad air, and learning to manage stress is vital. Despite temptations, city dwellers have excellent access to nutritious foods from around the world and should prioritize healthy eating. Selecting ripe fruits and fresh vegetables is key, and growing your own produce, when possible, offers both health and satisfaction. Sunbathing and regular exercise, even on rooftops or in small doses, help maintain vitality and can be adapted to urban life. Movement is natural and necessary, and even brief daily exercise can prevent the decline that comes from a sedentary lifestyle. Ultimately, there is no excuse for poor health—if one can’t be healthy in the city, they won’t magically achieve it elsewhere. Health is available to anyone willing to pursue it with dedication, and it is more valuable than wealth itself.
• This article is excerpted from a lecture delivered at the Convention of the American Natural Hygiene Society, then called the American Physiological and Hygiene Society, in New York City, April 26, 1949. It first appeared in the May 1949 issue of Dr. Shelton’s Hygienic Review.

• Success is often measured by wealth, status, or achievement, but the ultimate and most essential measure of success is health. No matter one’s accomplishments or material gains, when health deteriorates, everything else loses its value. Professional Hygienists observe that people from all walks of life seek help only when health is compromised—at that point, wealth, careers, and even family take a backseat to the urgent desire to feel well again. Natural Hygiene emphasizes that health is the foundation for all enjoyment and achievement in life; without it, the pleasures of success are hollow. Even the wealthiest individuals would trade their fortunes for restored health when faced with serious illness. True success, then, lies in understanding and living in harmony with nature’s laws—eating well, resting adequately, avoiding excess and stress, and pursuing balance. Natural Hygiene offers a practical and educational path to achieving vibrant health, but this requires consistent action, not just knowledge. Once a person achieves and maintains good health, they stand out—not because of their suffering, but because of their vitality, resilience, and youthful energy as others age. Real success is mastering the habits that support health and life itself, and this mastery opens the door to lasting happiness and fulfillment.

https://www.healthscience.org/wp-content/uploads/2023/03/V20-N4-Health-Science-July-August-1997.pdf

• The article emphasizes the importance of taking responsibility for one’s life by making thoughtful decisions and acting with purpose. It reflects on how many people look back with regret over wasted time and poor choices, often excusing their actions instead of owning them. The piece challenges readers to examine whether their lives align with their ideals or if they’re postponing change, waiting for a mythical “perfect moment.” It warns against empty resolutions and the destructive cycle of bad habits, asserting that real change requires determination and character. The past, while instructive, is unchangeable—what matters is the present and future. The text promotes Natural Hygiene as a means to achieve and sustain health, highlighting the value of attending its conferences for education, inspiration, and community. Ultimately, it argues that ordering one’s thoughts and actions wisely leads to a more satisfying life, with health and purpose serving as foundations for personal and societal well-being.

https://www.healthscience.org/wp-content/uploads/2023/03/V21-N1-Health-Science-January-February-1998.pdf

• This article first appeared in the June 1958 issue of Natural Hygiene, an early publication of the American Natural Hygiene Society.
• Dr. William Esser argues that illness is not an inevitable part of life but rather a result of man’s own actions, habits, and ignorance. He critiques society’s fear-driven approach to health, which is influenced by various professions—such as religion, medicine, and law—that promote the idea of disease as an unavoidable fate. This fear-based mindset diminishes vitality, reduces health standards, and leads to unnecessary suffering.
• Esser points out that many people have been conditioned to believe in the inevitability of illness, and society often turns to external solutions, like drugs or surgical interventions, which only treat symptoms rather than address the root causes. However, he stresses that illness is ultimately self-inflicted through improper lifestyle choices, poor self-awareness, and failure to live by natural laws. When individuals stop making themselves sick by adhering to healthy habits, they can become immune to disease.
• He also highlights the role of modern society in exacerbating these problems, noting that the fast-paced, stress-filled life and reliance on artificial stimulants like coffee and tobacco have led to an overtaxed nervous system, digestive issues, and premature aging. People often fail to maintain their health and longevity because they neglect the simple, natural principles of self-care in favor of modern, unhealthy habits.
• Dr. Esser advocates for a return to natural hygiene—living in harmony with nature’s laws through common-sense practices such as moderation, proper rest, and mindful living. He rejects the idea of relying on external treatments or complex, synthetic solutions to health. Instead, he encourages individuals to become self-aware and take responsibility for their health by understanding the true causes of illness and focusing on self-care.

Esser, W. L. (reissued 2018). “Does Education Educate? Health Science,
https://www.healthscience.org/wp-content/uploads/2021/09/TT_Esser_Spring_2018.pdf

• The article “Does Education Educate?” by W.L. Esser, reissued in 2018, examines the relationship between formal education and the development of critical thinking and informed decision-making, particularly in the context of health science. Esser questions whether contemporary educational systems truly “educate” in fostering independent thinking and self-directed learning or whether they primarily focus on rote memorization and the passive absorption of information.
• Esser critiques the current state of education, arguing that many educational institutions prioritize standardized testing and conformity over deeper, reflective learning. He highlights the gap between the theoretical goals of education—such as fostering critical inquiry, autonomy, and problem-solving skills—and the realities of classroom practices that often emphasize obedience to prescribed curricula and procedures.
• The article also touches on the implications of this disconnect for health education, where informed decision-making is crucial. Esser suggests that in the field of health science, an educated individual should be able to engage critically with health-related information, question assumptions, and make evidence-based decisions about personal well-being. However, he posits that traditional education does not adequately prepare individuals for this kind of informed engagement, resulting in a population that may be well-versed in specific facts but lacks the ability to analyze and apply them effectively in real-world situations.
• In conclusion, Esser calls for a transformation in educational practices to foster true “education better”—one that equips students with the knowledge and the tools to think critically, make decisions autonomously, and engage meaningfully with the world around them.

• Life passes quickly, and the physical decline often accepted as “normal aging” is actually a warning of neglected health and poor habits. True vitality requires consciously living in alignment with natural laws, rather than indulging in harmful behaviors that lead to preventable suffering and diminished life.

https://www.healthscience.org/wp-content/uploads/2022/01/Summer-2020-Timeless-Teachings.pdf

• In the article “The Real Road to Health” by W.L. Esser, initially published in Health Science and reissued in January 2022, the author outlines a philosophy of health that goes beyond medical treatment and addresses the root causes of illness. Esser argues that true health is not simply the absence of disease but the result of a holistic approach to life that integrates physical, mental, and spiritual well-being.
• Esser stresses that the “real road to health” involves making informed, intentional choices in every aspect of life, including nutrition, exercise, rest, and emotional balance. He critiques the over-reliance on pharmaceutical interventions and medical treatments that focus on managing symptoms rather than addressing the underlying causes of poor health. Instead, Esser promotes self-awareness and personal responsibility as key elements in achieving and maintaining optimal health.
• The article emphasizes the importance of a natural and preventative approach to well-being, including the need for proper nourishment through whole foods, regular physical activity, and practices that support mental clarity and emotional stability. Esser also highlights the significance of fostering a positive outlook on life and the role of spirituality in promoting overall health.
• In the reissue, Esser’s message resonates with contemporary concerns about chronic diseases, lifestyle-related health issues, and the growing interest in holistic health practices. His emphasis on personal empowerment, self-care, and illness prevention serves as a timeless guide to achieving lasting health and well-being.
