About

Irving Davidson, a proud Brooklynite, dedicated his life to the legal profession. In the early stages of his career, he formed a valuable partnership with the renowned publicist Jack Dunn Trop. Together, they passionately worked to advance the vision of the National Health Association, making a lasting impact in the realm of public health advocacy.

In 1944, Irving Davidson and Jack Dunn Trop, driven by a shared vision, rallied a group of like-minded individuals to form the New York Natural Hygiene Society. Convening in the office of an insurance agent named Norman Osborn, this modest gathering was more than just a meeting of minds—it marked the beginning of a movement. Though small in number, their steadfast commitment to the transformative principles of Natural Hygiene set them apart. Their efforts were not merely about promoting a healthier lifestyle; they were a passionate advocacy for holistic well-being, laying the foundation for a growing movement dedicated to better health and vitality.

In 1946, Irving Davidson and Jack Dunn Trop founded the Graham Natural Hygiene Society in New York City, a local group dedicated to promoting holistic health principles. The name “Graham” pays tribute to Rev. Dr. Sylvester Graham, America’s pioneering advocate for healthy living through a balanced approach to diet, exercise, sleep, hygiene, appropriate clothing, and the healthy expression of sexuality, emotions, and mental well-being. In the 1830s, Graham launched the Crusade for Health and Physiological Reform through his influential lectures and writings, inspiring countless individuals to embrace his lifestyle and become known as “Grahamites.” His groundbreaking work laid the foundation for a movement that would continue to resonate through generations, shaping the future of natural health advocacy.

One day, during a conversation, Jack Dunn Trop proposed an inspiring idea to Irving Davidson: Why not elevate their efforts by founding a national organization? Drawing on the legacy of a thriving Natural Hygiene Society from the 1840s, Trop saw a remarkable opportunity to revive and modernize the movement. He envisioned a revitalized national platform that could build on the successes of the past while expanding its reach and impact for a new generation. This bold idea sparked a shared commitment to take their work to the next level and bring the principles of Natural Hygiene to a broader audience.

Davidson and Trop took a decisive step forward by drafting a letter to Dr. Herbert M. Shelton, a respected leader in the Natural Hygiene movement, proposing the creation of a national society. Shelton’s response was both enthusiastic and supportive. He offered not only his expertise but also his financial backing: “If you proceed with this, I will finance it and handle all the organizational details.” This pivotal response marked a turning point in the movement’s evolution, providing the foundation for a broader, more influential network dedicated to the principles of Natural Hygiene. With Dr. Shelton’s invaluable guidance and resources, their ambitious vision began to take shape, ultimately leading to a national movement that would inspire countless individuals to embrace healthier, more holistic lifestyles.

It is remarkable that New York City, the birthplace of the Natural Hygiene Movement in 1832 and the site of Rev. Dr. Sylvester Graham’s groundbreaking first lectures, would also serve as the backdrop for the revival of a national society on June 28, 1948. This pivotal moment, championed by the influential Dr. Herbert M. Shelton, marked a new chapter in promoting holistic health, reconnecting the movement’s roots with a modern vision. The event not only honored Graham’s legacy but also set the stage for a renewed national effort to advance the principles of Natural Hygiene.

At this historic meeting, Davidson and a distinguished group of leaders in health and wellness gathered. The meeting included Dr. Herbert M. Shelton, Dr. William Esser, Dr. Christopher Gian-Cursio, Dr. Gerald Benesh, Dr. Jesse Mercer Gehman, Jack Dunn Trop, and Symon Gould. Together, this pioneering group established the American Physiological and Hygienic Society. Drawing inspiration from a legacy nearly a century old, they organized a landmark convention in April 1949, during which they boldly rebranded the society as the American Natural Hygiene Society. This pivotal decision set the stage for the organization’s evolution, eventually becoming the National Health Association in 1999. Through this transformation, the organization solidified its unwavering commitment to advancing health and wellness for all, fostering a movement that continues to inspire healthier lifestyles today.

At the inaugural convention, Irving Davidson and Symon Gould stepped into the crucial roles of co-chairmen for the week, overseeing a dynamic and impactful event. Their collaborative leadership, alongside Jack Dunn Trop, proved instrumental in securing extensive media coverage and amplifying their message. One of their key achievements was facilitating a radio address delivered by Dr. Herbert Shelton, which helped spread the movement’s core principles to a broad and diverse audience. Together, their efforts played a pivotal role in shaping the convention’s success and expanding the reach of the Natural Hygiene message.

As co-chair, Irving Davidson brought his charm and wit to the forefront, captivating the audience with his effortless storytelling and sharp humor. Among the distinguished guests was radio superstar and Natural Hygienist Fred Allen, whose presence added star power to the event. Davidson’s clever remarks, laced with insightful allusions to healthy living, kept the atmosphere both lively and thought-provoking. The talented Jack Haley, a beloved comedian on stage and screen, shared the spotlight with Allen and his wife. Together, they helped create an unforgettable atmosphere, blending entertainment with the powerful message of Natural Hygiene.

The conference boasted an impressive lineup of speakers, each a leading expert in their field. Among them were Dr. Herbert Shelton, Dr. Christopher Gian-Cursio, Dr. William Esser, Dr. Gerald Benesh, Dr. Jesse Mercer Gehman, and Jack Dunn Trop, along with Dr. Max Warmbrand, Dr. Robert Anderson, Dr. Luis Mendiola, and George David Boutwell. With their diverse backgrounds and deep expertise, these speakers were poised to deliver valuable insights and spark thought-provoking discussions, offering a wealth of knowledge and leaving a lasting impact on all attendees.

Several key business meetings of the American Natural Hygiene Society were held during the conference, marking a significant moment in the organization’s growth. Dr. Herbert Shelton was re-elected as president, a testament to the Society’s trust in his leadership for another term. Dr. Christopher Gian-Cursio was appointed vice president, bringing a wealth of expertise and vision to the role. Irving Davidson was named Secretary-Treasurer and was tasked with ensuring robust financial management and strategic planning for the Society’s future initiatives. This leadership team set the stage for a new chapter of growth and impact in the movement.

From its inception, Irving and his wife, Adele, were proud and dedicated Board Members of the American Natural Hygiene Society (ANHS). During his term as president from 1974 to 1975, Irving’s unwavering commitment to the organization’s mission left an indelible mark on its growth and influence. Together, they became charter members of the Society’s Century Club, a testament to their enduring dedication to promoting health and wellness. As founding members of the New York City Chapter of the National Health Association and vice-president of the New York Vegetarian Society, they played a pivotal role in cultivating a vibrant community centered around healthy living. Their legacy of leadership, passion, and service inspires and drives positive change in the movement for holistic health.

Irving Davidson was an exceptional writer, and his influential contributions to Health Science magazine have left a lasting legacy. A standout example of his work can be found in the November/December 1990 issue, where he penned a compelling article on the lives of two prominent natural hygienists, Helen and Scott Nearing. Originally published in the October 1955 edition of Dr. Shelton’s Hygienic Review, their inspiring story remains essential for anyone interested in the principles of natural health and holistic living. Davidson’s thoughtful exploration of their journey offers timeless insights into the power of healthy, conscious living.

Davidson passionately argued that embracing natural hygiene is essential for humanity’s survival and well-being. As we look to the future, we face significant challenges that threaten our health. The shifting economic landscape has highlighted the dangers of over-reliance on pharmaceuticals and the harmful effects of drugs. In response, now more than ever, we must prioritize holistic health programs that address the diverse needs of individuals. Adopting more effective methods for treating illness and preventing disease is crucial, ensuring a healthier world for all. Davidson’s call to action serves as a powerful reminder of the importance of natural, preventive care in safeguarding our collective future.

Irving and Adele were unwavering pillars of strength for the movement, providing steadfast support to the society throughout the years. In April 1949, Irving proudly co-hosted the society’s inaugural convention at the Diplomat Hotel in New York City, a landmark event that marked a defining moment in its history. Together, they served as dedicated board members of the National Health Society (NHS) from 1972 to 1975, demonstrating their deep commitment to its mission. Irving further showcased his leadership during his two-year tenure as president from 1973 to 1975, where he guided the organization with vision and determination, steering it toward a promising future. Their combined efforts left an enduring impact, ensuring the continued growth and success of the movement.

On November 15, 1990, the American Natural Hygiene Society (ANHS) lost one of its most esteemed leaders and educators, Irving Davidson. A co-founder, former president, and lifelong member of the society, he passed away at the age of 86 from natural causes in his beloved home in Brooklyn, New York. Irving’s contributions to the movement and his unwavering commitment to promoting natural health left a lasting legacy that continues to inspire those who follow in his footsteps.

Excerpt From
The Greatest Health Discovery
Sylvester Graham, Russell T. Trall, and Herbert M. Shelton

“Rigorous Inquiry: The Hygienist’s Path to Health Through Critical Examination”

A natural hygienist is someone who constantly challenges established norms and beliefs, recognizing that a single misstep can set off a chain of errors, leading to a long and often burdensome journey of physical and mental strain. They understand that starting on the wrong path can snowball, compounding mistakes that affect both body and mind. A true hygienist is willing to question widely accepted assumptions, many of which are taken as self-evident truths. Rather than merely examining isolated aspects, they explore every dimension of a more significant issue, guided by a deep skepticism. This rigorous scrutiny gives rise to the groundbreaking discoveries of Natural Hygiene, reshaping our understanding of health and well-being.

“Challenging Misconceptions: The Natural Hygiene Call for Evidence-Based Health”

Natural Hygiene boldly confronts the confusion created by misleading ideas, harmful beliefs, pervasive myths, and unnatural practices, often deeply rooted in societal traditions despite having no factual basis. By questioning these entrenched norms, Natural Hygiene advocates for a return to evidence-based principles that promote true health and well-being.

“Collaboration with Nature: The Hygienist’s Path to Self-Mastery and Well-Being”

The natural hygienist adopts a mature mindset that prioritizes self-mastery rather than attempting to control nature. To engage in conflict with nature would be to work against one’s own well-being. Instead, he understands that he collaborates with nature, aligning his actions with its principles in the shared pursuit of health and survival. This harmonious relationship fosters a deep respect for the natural world, acknowledging that true well-being is found in working with, rather than against, nature’s inherent wisdom.

“Critical Thinking and Scientific Integrity: The Hygienist’s Approach to Truth”

The natural hygienist empowers themselves to think critically and independently, discerning the difference between genuine facts and widely accepted biases, between true reasoning and mere rationalization. They understand the importance of rigorously evaluating evidence, distinguishing it from the tangled illusions of myth and superstition. For the hygienist, science is not just a body of knowledge but a method—one that is rigorously tested through the undeniable lens of experience and grounded in careful observation of diverse phenomena. Through this disciplined approach, rooted in comparative anatomy and natural law, the hygienist seeks to understand the true foundations of health and well-being.

“Challenging the Status Quo: The Hygienist’s Role in Advancing Progress”

The hygienist plays a crucial role in challenging established values and questioning long-held traditions and practices. This essential questioning can unsettle some, disrupting their sense of security. When the hygienist critiques beliefs that many find comforting or ingrained, the typical response is often hostility or rejection rather than open-minded acceptance. Unfortunately, the criticism of conventional wisdom is rarely met with praise; instead, they are usually labeled as deviant, eccentric, or even quacks. Such labels can lead to social alienation and persecution. However, through these courageous challenges, true progress is made, as the hygienist’s willingness to question the status quo paves the way for deeper understanding and meaningful change.

“Culture and Identity: The Shaping of Human Potential”

Children and adults alike are profoundly shaped by the unique characteristics of the groups into which they are socialized, often making individuals “products” of their culture. This cultural influence can overshadow their biological potential, leading people to express the norms and experiences of their environment more than their innate abilities. In anthropology, “culture” refers to the man-made elements of our surroundings and the socially learned behaviors that define our identities. Human history, intertwined with our present experiences, plays a pivotal role in shaping the trajectory of our future. It is essential to recognize that cultures and minds manifest in a rich diversity of forms, reflecting the complexity and depth of human experience.

“Interconnectedness and Compassion: The Hygienist’s Vision for a Harmonious World”

The natural hygienist not only advocates for their own well-being but also feels a deep responsibility to support and uplift the lives of others. Their approach transcends the natural aggressiveness often seen in the world, instead embracing core principles such as nonviolence, cooperation, and mutual support. Remarkably, the energies typically associated with aggression can be channeled into social collaboration and constructive action. The hygienist understands the interconnectedness of all living beings and fosters a profound sense of kinship with the world around them. Each human life is intricately linked to our own, serving as a reminder that we are all integral threads in the larger tapestry of humanity.

“Beyond Survival: Embracing Peaceful and Compassionate Nourishment”

The natural hygienist firmly believes that humans do not need to kill for food, as it is neither essential nor natural. Our food choices, much like our preferences for cigarettes or alcohol, are primarily shaped by culture rather than biological necessity. While wild animals kill purely to satisfy their hunger, driven by survival instincts, humans possess the capacity to transcend these primal urges. There is no justification for reverting to the violence of the natural world. Instead, we should strive to cultivate a more peaceful and enlightened approach to nourishment—one that values reason over harm and fosters a harmonious relationship with all living beings and the environment around us.

“Unlocking Potential: The Journey to Self-Mastery and Personal Growth”

The natural hygienist inspires individuals to unlock and enhance their innate potential, championing a journey toward fuller development through the power of intellect and self-awareness. Rather than resigning to self-destructive habits, we are called to embrace our capacity for growth and cultivate a healthier, more fulfilling life. By tapping into our natural abilities and making conscious choices, we can create a path toward greater well-being and personal transformation.

“The Illusion of War: Moving Beyond Violence Toward Peaceful Resolution”

The hygienist understands that neither peace nor war is driven by instinct; instead, physical violence is a construct of human society. War does not arise from biological imperatives but from artificial social conditions. Unlike gorillas and chimpanzees, who possess tremendous strength yet rarely engage in conflict, humans have created a world where violence is pervasive and normalized.

Modern warfare destroys our most capable individuals, often leaving the less fit to survive—those suffering from mental and physical ailments. In this tragic cycle, the strongest are sacrificed while the weakest endure. Modern war, in essence, enacts an unnatural selection that favors the least capable among us.

We must recognize that the brutality of physical combat is an outdated relic with no place in our current world. True conflict resolution should draw upon the constructive power of dialogue, not the destructive force of weapons. We can pave the way for a more peaceful, enlightened future by embracing communication over violence.

“Embracing Health: Viewing Disease as a Path to Healing”

The natural hygienist adopts a positive, empowering perspective on health, free from the fear of disease. Rather than seeing illness as an enemy, he views the disease process as a vital opportunity for healing—a natural response that signals the body’s innate cleansing and restorative mechanisms. By aligning with the body’s wisdom and supporting its natural processes, the hygienist transforms disease from a threat into an ally, guiding the individual toward greater well-being and vitality.

“Compassionate Wisdom: The Path to Humane Living”

To the natural hygienist, facts alone are of little value unless they are deeply understood and applied compassionately. A truly developed mind embraces all facets of the human experience, leaving no aspect untouched. The ultimate goal is to cultivate humane individuals by leading through example—embodying kindness and empathy in a way that inspires others to follow and grow in their own journey toward compassion and understanding.

“Bridging Knowledge and Action: The Hygienist’s Path to Lasting Change”

The hygienist understands that simply presenting the truth is often not enough. While facts may be clear, they are not always fully grasped or embraced. Even when understood, they are not guaranteed to inspire change or lead to action. Bridging the gap between knowledge and behavior is crucial, ensuring that awareness translates into meaningful transformation.

“Redefining Success: Cultivating the Human Spirit Over Material Gains”

The natural hygienist seeks to redefine success, shifting the focus from material achievements to cultivating the human spirit. This reimagined concept of success emphasizes a deep commitment to the welfare of others and the improvement of society. It encourages us to prioritize compassion, connection, and community over pursuing possessions and status, fostering a more prosperous, more meaningful life.

“Embracing Humanity: The Hygienist’s Path to Kindness, Cooperation, and Connection”

While a natural hygienist may experience anger, responding calmly rather than resorting to violence is key. Instead of clinging to malice, one should seek peace before the day ends, for there is no substitute for the genuine warmth of human kindness. The natural hygienist’s ultimate goal is cultivating healthy individuals, starting with a firm commitment to humanity. This means prioritizing civility over cleverness, cooperation over competition, and a spirit of brotherhood over isolation. True love is found in our ability to connect, cherishing those connections. It is vital to reject prejudice in favor of understanding, embrace altruism over selfishness, and recognize the intrinsic worth of human beings rather than valuing them by their wealth.

How I Learned of Natural Hygiene and What it Has Meant to Me

Many years ago, I picked up my first copy of Dr. Shelton’s “Hygienic Review” and experienced my initial glimpse of the Natural Hygienic comprehensive system of life. From then on, all my reading of the past was revealed as pieces in the jigsaw puzzle of Natural Hygiene. I thus passed from fragmentary reading on health to the “wholism” of the literature of Natural Hygiene. This larger picture has become more and more significant with the passing of time. It has given me an all-pervading sense of courage in living, and the belief that disease and health are two sides of the same coin, locked in an indivisible unity. This learning also indicated that disease is a health impulse that restores the body to its biological equilibrium, and the bacteria are the friendly agents of that disease process. Natural Hygiene has helped me to turn around and see the real, breath-taking mountain view of health. After having beheld this magnificent promised land, never will I return to the nondescript agonies and confusion of valley-living; and I shall continue to climb higher and higher until I’ve experienced every worth-while result of such climbing. For clearest vision in your climbing, make sure that you have the principles and precepts of Natural Science securely in mind; and for footsuredness, that the practices and habits of Hygiene living are with in every step.

• The human body is compared to a valuable treasure that can either enrich the poor through sustained health or become a burden through illness and toxemia. Like a wealthy man who is entrusted with his riches for the benefit of humanity, a person is the custodian of their body and must preserve it as a life-long asset. If neglected, the body’s health becomes a liability, leading to sickness and death, which Dr. Shelton likens to financial bankruptcy.
• To preserve the body’s wealth, one must protect it from physical, emotional, and mental leaks. This includes avoiding excesses, emotional stress (such as anger, fear, and anxiety), and ensuring proper rest and relaxation. The body’s “treasury” should be safeguarded through healthy habits, like good nutrition (with biologically sound foods), clean air, exercise, and sufficient sunlight. The most precious asset within this treasure is the life force, which manifests as natural immunity and body resistance. When this life force is compromised, the body becomes vulnerable to disease and decay.

Davidson, Irving. (1955, January). The Gift of Health. Journal of Natural Hygiene, V1(N5), 15, 22.
https://www.healthscience.org/wp-content/uploads/2023/03/Volume-1-N5-Natural-Hygiene.pdf

• In The Gift of Health, Irving Davidson emphasizes that health is the most valuable and precious gift one can possess, surpassing wealth, power, or material possessions. He quotes various historical thinkers, such as Solomon, Cicero, Horace, and Schopenhauer, all of whom recognized the importance of health as the foundation for a fulfilling life. Health, Davidson argues, is essential for happiness, and without it, even the most significant accomplishments or wealth lose their meaning.
• Davidson points out the folly of sacrificing health for any other pursuit, whether it be wealth, fame, or success. He highlights the wisdom of figures like Ralph Waldo Emerson, who stated that “the first wealth is health,” and Theodore G. Mitchell, who believed that maintaining good health prevents much of life’s misery. He also underscores that health is often taken for granted until it is lost, and once lost, it can’t be regained with wealth or possessions.

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

• Irving Davidson critiques the Natural Hygiene movement and its supporters for inadvertently causing harm to the very practitioners they claim to support. He draws attention to the struggles faced by Natural Hygienic practitioners, who advocate a lifestyle of fasting, rest, exercise, sunshine, and simple natural foods to heal the body. Despite their positive impact, these practitioners often face persecution and legal trouble, and many are driven out of their profession due to a lack of understanding or support from their own community.
• Davidson argues that some well-intentioned Natural Hygienists contribute to the persecution of practitioners by recklessly revealing their locations or mentioning their names to hostile professionals. This often leads to legal action or social backlash. He also points out that while practitioners do not “cure” diseases, they create the proper conditions for the body to heal itself, and the movement’s principles must be protected.
• Davidson proposes a set of “precautionary practices” or a “New Decalogue for Natural Hygienists,” which includes guidelines for supporters to follow to safeguard practitioners. These rules urge caution in revealing practitioners’ identities, avoid discussing practitioners in adversarial contexts, and prevent legal or medical authorities’ entrapment or exploitation of practitioners.

• In Food Can Be Strange, Irving Davidson explores a variety of fascinating and unusual facts about food, aiming to both inform and entertain readers while delving into the curiosities of diet and natural hygiene. The author presents a collection of peculiarities and surprising truths about different foods that often challenge common perceptions.

• Irving Davidson explores the dangers and drawbacks of medical diagnoses. He begins by illustrating how misdiagnoses have led to unnecessary deaths and suffering, such as cases where people were told they had only a few months to live but survived for decades or were incorrectly treated for conditions they did not have. Davidson emphasizes that an incorrect diagnosis can be just as dangerous as a correct one, as it often leads to unnecessary treatments or surgeries that don’t address the root cause of the illness.
• Davidson warns against the psychological impact of diagnoses, as they can induce fear, uncertainty, and stress, which worsen a person’s condition. This fear, he argues, diminishes a person’s rationality and ability to make informed decisions. Fear of illness can paralyze individuals, making them irrational and more vulnerable to medical interventions.
• He proposes that a better approach to health is to focus on natural living, emotional balance, and the principles of Natural Hygiene rather than relying on doctors or diagnoses. Davidson advocates for rejecting fear and trusting in the body’s ability to heal through healthy habits instead of succumbing to the terror and stress induced by medical diagnoses.

Davidson, I. (1956, Nov). The Nature of Tooth Decay. Journal of Natural Hygiene, V2(N2), Pg22-24.
https://www.healthscience.org/wp-content/uploads/2023/03/Volume-2-N2-journal-of-Natural-Hygiene-November-1956.pdf

• The article examines the persistent mystery of tooth decay, which affects 93% of Americans and costs nearly a billion dollars annually. Despite the teeth being the hardest part of the human body and being able to survive for millions of years in the ground, they are incredibly vulnerable to decay during life. The cause of tooth decay remains elusive, but some theories suggest that a pure bloodstream may nourish healthy teeth and that decay often originates from within the tooth itself.
• Tooth decay is particularly prevalent in modern societies that rely on processed foods like white bread, sugar, and soft drinks. Dr. Weston A. Price’s research on isolated, pre-industrial populations found that tooth decay was virtually nonexistent among these groups, who maintained traditional diets and farming practices that preserved soil fertility. When these groups adopted modern foods, tooth decay and physical degeneration became common.
• The article emphasizes that good dental health is tied to overall body health and that poor nutrition is the primary cause of tooth decay. It argues that focusing on diet and proper hygiene is more effective than conventional dental treatments like tooth brushing. It also highlights that certain natural habits, such as finger-massaging the gums or eating raw fruits and vegetables, can improve dental health. Ultimately, living according to the principles of Natural Hygiene—emphasizing a natural diet, proper nutrition, and stress management—can prevent and even reverse tooth decay.

• Natural Hygiene is a holistic approach to health that emphasizes the importance of aligning our lifestyle with the natural laws of biology, physiology, psychology, and sociology. It seeks to eliminate unhealthy habits, traditions, and substances that detract from well-being, promoting instead a lifestyle that supports both physical health and mental peace. This philosophy advocates for the consumption of wholesome, natural foods, adequate sunlight, fresh air, and the exclusion of detrimental influences like drugs and processed foods. Ultimately, Natural Hygiene represents a significant shift towards living in harmony with nature, enabling individuals to take control of their health and happiness by adhering to the essential needs of life.

https://www.healthscience.org/magazine/conference-program-chicago-1961/

• Aging is not defined by the number of years lived but by the condition of the body and how one has lived. While chronological aging is inevitable, biological aging is influenced by lifestyle and is largely under personal control. The aging process begins at conception and accumulates over time through physiological and psychological stresses, with illness and poor habits accelerating degeneration. True aging sets in when the body can no longer regenerate cells as quickly as they deteriorate, leading to physical and mental decline. However, aging can be graceful and fulfilling if one maintains emotional balance, creative interests, social connections, and a lifestyle rooted in Natural Hygiene—emphasizing proper nutrition, rest, fresh air, sunlight, and physical activity. Aging should not be feared or masked by superficial youthfulness, but embraced as a stage of continued growth, wisdom, and joy. One must accept the loss of youthful traits, including sexual vigor, with dignity rather than grief. Ultimately, whether life ends in nothingness or something beyond, it should be lived fully and faced with peace.

https://www.healthscience.org/wp-content/uploads/2023/03/CONVENTION-1962.-Miami-Beach-FL.pdf

• Each year, billions of dollars are raised and spent on disease research and treatment—mostly to suppress symptoms rather than eliminate causes. This approach reflects a backward priority: “millions for disease and not one cent for health.” In contrast, Natural Hygienists focus on preventing disease by building health through proper living, avoiding harmful habits, and rejecting wasteful medical and consumer practices.
• By avoiding drugs, processed foods, tobacco, alcohol, and stimulants, the Hygienist not only protects their health but also saves immense amounts of money, avoiding the “high cost of dying” that burdens the general population. With millions suffering from chronic illnesses and billions spent on preventable health problems and vices, Natural Hygiene offers both a healthier and more economical way of life.
• Because Natural Hygiene frees individuals from physical and financial disease traps, the author argues that Hygienists should support the movement financially—suggesting contributions to organizations like the American Natural Hygiene Society to help spread these life-saving principles. Supporting Natural Hygiene is framed as a patriotic and humanitarian duty: promoting the health, strength, and future of the nation.

• This passage celebrates the human body as nature’s greatest miracle—a marvel of design, efficiency, and self-regulation. It highlights the astonishing complexity of our biological systems, from the heart and nervous system to enzymes, hormones, and cells, all operating automatically and intelligently without conscious effort. The body constantly regenerates, maintains balance, and responds to threats with precision that no machine or human intellect can match.
• However, modern living and artificial habits have dulled our natural instincts and disrupted this internal harmony. Unlike animals, humans have strayed from nature’s laws, leading to illness and degeneration.
• According to Natural Hygiene, the body is self-healing and governed by immutable laws of life. When we respect these laws—through proper nutrition, rest, exercise, sunlight, emotional balance, and abstaining from harmful habits—the body thrives and maintains health. Disease arises not from a broken body, but from the violation of natural laws. The body always does the right thing—trying to repair and survive—even when we mistreat it.
• The conclusion urges deep respect and care for the body, recognizing it as the only one we’ll ever have. With proper hygienic living, one is fully capable of leading a long and healthy life.

https://www.healthscience.org/wp-content/uploads/2023/03/CONVENTION-1964.-New-York-City.pdf

• The natural hygienist is someone who courageously challenges widely accepted beliefs, social norms, and cultural habits in pursuit of truth and health. Understanding that a single wrong assumption can lead to a chain of errors, the hygienist questions deeply rooted myths and practices, replacing them with principles grounded in experience, reason, and nature. Rather than seeking to control nature, the hygienist works in harmony with it, striving to live intelligently and in balance. Often viewed as eccentric or threatening by society, the hygienist accepts rejection but remains committed to education and reform, believing in humanity’s ability to unlearn harmful habits and adopt healthier ones. Emphasizing compassion, cooperation, and peace, the hygienist rejects violence, war, and exploitation—whether of people or animals—in favor of a humane, enlightened existence. He understands disease not as an enemy but as the body’s effort to heal, and seeks to foster well-being through gentle, rational living. Ultimately, the natural hygienist aspires not only to personal health but to uplift humanity by prioritizing kindness, spiritual growth, and moral integrity over material success or conformity.

https://www.healthscience.org/wp-content/uploads/2023/03/CONVENTION-1965.-Cleveland-OH.pdf

• The natural hygienist is deeply rooted in humanitarian values, social responsibility, and a commitment to truth, making their role in public and moral issues essential. As a champion of natural laws and a fighter against ignorance, the hygienist brings light to a world clouded by conventional errors and health misinformation. Courage, nonconformity, and a dedication to truth are essential traits, enabling the hygienist to challenge societal norms and inspire others through example rather than empty theory. Hygiene is not merely a health practice but a philosophy of living in harmony with natural laws—focusing on education, prevention, and self-responsibility rather than drugs and external cures. It demands self-awareness, a return to values aligned with biological and social well-being, and an emphasis on internal order over external fixes. True hygienists promote cooperation, altruism, and shared human responsibility, recognizing that a healthy society begins with healthy individuals. They view isolation as unnatural and strive to live more openly, connected with others. Ultimately, their purpose is not only to live well but to inspire and guide others through lived example, embodying the principles they advocate and contributing to a more harmonious, healthy, and enlightened world.

• Emotions profoundly influence physical health, with negative states such as anxiety, anger, and frustration contributing to illness, exhausting the nervous system, and aggravating existing conditions. Conversely, positive emotions like love, laughter, kindness, and tolerance support digestion, elimination, and overall vitality. The modern lifestyle—obsessed with wealth, stimulation, and indulgence—creates overwhelming stress and enervation, often leading to physical and emotional breakdowns. However, emotional resilience depends not on avoiding hardships, but on how one responds to them. Constructive coping methods include cultivating patience, engaging in meaningful work, maintaining hobbies, expressing emotions healthily, and practicing self-awareness. Words, too, wield immense power, capable of healing or harming. Literature, friendships, and even small acts of kindness can transform suffering into connection and strength. Notable thinkers and healers suggest channeling negative energy into physical movement or creative pursuits, adopting a mindset of gratitude, and learning to detach from pain by not identifying with it. Nourishing the body with proper food also supports emotional stability. Ultimately, emotional poise—marked by calmness, self-mastery, and optimism—is essential for health and a meaningful life. The emotionally balanced person responds to adversity with patience, compassion, and wisdom, turning inner struggles into opportunities for personal growth and societal contribution.

• Sleep remains a mysterious but essential function of life, occupying roughly a third of our existence and profoundly influencing our physical, mental, and emotional well-being. Despite varied theories, scientists still cannot fully explain what sleep is or why we need it, though its restorative power is widely acknowledged. People’s sleep patterns reflect their personalities, with some finding sleep effortless and refreshing, while others suffer from insomnia or fear sleep itself. Historical figures had unique sleep habits—some relying on short naps, others on long rest periods—and even odd rituals like aligning beds to magnetic fields. Physiologically, sleep involves shifts in blood pressure, heart rate, and brain activity, and its disruption leads to emotional instability, cognitive decline, and even disease. Natural Hygiene emphasizes sleep as the body’s natural healing process, crucial for energy restoration and metabolic repair, especially for the brain and nervous system. Modern society, however, often undermines this natural rhythm through overstimulation, poor habits, and reliance on artificial aids like sleeping pills, which can cause more harm than good. Solutions for better sleep include relaxation techniques, a proper sleep environment, and avoidance of stimulants and mental overactivity before bed. Ultimately, sleep is Nature’s indispensable tool for rejuvenation—far more than just a break from wakefulness—and must be respected as a cornerstone of health.

• This article presents a perspective on microbial diseases, emphasizing the idea that germs do not cause disease but rather emerge as part of the body’s natural response to illness, functioning as scavengers that help restore health. Pierre Jacques Antoine Bechamp’s theories suggest that life is organized at a microscopic level by “microzymas,” which serve as the foundational building blocks for cells and can evolve into various microorganisms depending on their environment. When in a healthy state, these microzymas facilitate well-being, while in sickness, they can become harmful; however, this duality shows that disease can also act as a healing process. The passage advocates for biological living and a diet rich in raw fruits, vegetables, and nuts while warning against processed foods, which disrupt health and make individuals susceptible to diseases. It underscores the importance of a biologically balanced environment, arguing that microbes are essential allies in maintaining health rather than enemies that need to be eliminated.

• The natural hygienist plays a crucial role in society by promoting essential, humanitarian values and addressing moral issues in public life. Armed with knowledge from various philosophical teachings, hygienists strive to influence positively those around them, advocating for personal growth and the importance of discerning truth. They emphasize that true freedom comes from doing what is right and healthy, which ultimately aligns with personal desires. The values most people hold are often conditioned from a young age, making it easy to pursue misguided goals. Furthermore, the hygienist recognizes that inner health is key to creating a better world, as individuals reflect their internal state in their external environment. Proper care should begin even before birth, highlighting the importance of a healthy mother for the well-being of the child, as hospitals can pose greater risks than home births. Lastly, while nature has elements of aggression, it is the instinct for cooperation that proves to be biologically essential, underscoring the significance of community and mutual support.

• The human body is a miraculous, self-regulating organism that represents one of evolution’s most remarkable achievements. It operates with astonishing complexity and precision, managing countless functions—digestion, circulation, immune response, regeneration—without conscious direction. Each organ and system, from the heart and nervous system to enzymes and hormones, functions with efficiency unmatched by any human invention. The body continuously renews itself through cellular regeneration and innate intelligence, performing tasks no human mind could orchestrate. Natural Hygiene teaches that the power to heal resides within the body itself, and that health depends on obeying the immutable laws of life: proper food, clean air, rest, exercise, emotional balance, and avoidance of harmful habits. Unlike animals, whose instincts guide them toward what supports health, modern humans have dulled their natural instincts through artificial lifestyles. Still, the body never acts wrongly—it always strives to maintain or restore health, even in the face of abuse. Respecting and cooperating with this internal wisdom through Natural Hygiene allows the body to perform its healing work and endure for a lifetime.
