Sun Therapy

From Nobel Prize Recognition to Modern Reassessment

The therapeutic use of sunlight, also known as heliotherapy, has roots in ancient medicine. Cultures such as the Egyptians, Greeks, and Romans prescribed sun exposure for health and vitality, believing it could improve physical and spiritual well-being (Holick, 2016). By the 19th and early 20th centuries, heliotherapy became widely adopted in Europe and North America as a treatment for conditions like rickets, skin diseases, and tuberculosis, particularly in sanatoria where sunlight and fresh air were emphasized (Sunlight, Outdoor Light, and Light Therapy in Disease Management, n.d.).

Nobel Prize Recognition

The scientific validation of light therapy was established through the work of Niels Ryberg Finsen. Finsen demonstrated that concentrated light, particularly ultraviolet rays, could be used to treat lupus vulgaris, a severe cutaneous form of tuberculosis. For this innovation, he was awarded the 1903 Nobel Prize in Physiology or Medicine “in recognition of his contribution to the treatment of diseases, especially lupus vulgaris, with concentrated light radiation” (Nobel Prize, 1903/2024). His research marked a pivotal moment in medical science, as it represented one of the earliest successful applications of light as a therapeutic modality (Grzybowski et al., 2016).

Decline of Traditional Sun Therapy

Despite its early success, enthusiasm for heliotherapy declined in the mid-20th century. The discovery of antibiotics, such as streptomycin in the 1940s, rendered heliotherapy obsolete for treating tuberculosis (Daniel, 2006). Furthermore, as scientific understanding of ultraviolet radiation advanced, physicians began to recognize the dangers of excessive sun exposure, including premature aging of the skin, immune suppression, and increased risk of skin cancers (Narayanan et al., 2010). Public health messages shifted from promoting unregulated sun exposure to encouraging cautious, limited exposure combined with sun protection.

Contemporary Perspectives

Today, sunlight is still acknowledged as vital for vitamin D synthesis, which is critical for bone health, immune regulation, and overall wellness (Holick, 2007). Modern medicine has also refined phototherapy, using specific wavelengths of artificial light for targeted conditions such as psoriasis, vitiligo, neonatal jaundice, and seasonal affective disorder (Roelandts, 2002). This demonstrates how the legacy of heliotherapy has evolved from generalized “sun cures” to scientifically controlled light-based treatments.

However, in modern times, a global trend of sun avoidance has contributed to widespread vitamin D deficiency. Public health campaigns emphasizing sun protection, urbanized lifestyles, and increased time spent indoors have led many individuals to receive insufficient sunlight exposure. Vitamin D deficiency is now recognized as a global public health issue, affecting over one billion people worldwide (Holick, 2007; Cashman et al., 2016). Consequences include increased risk for osteoporosis, impaired immune function, cardiovascular disease, and even mood disorders. Ironically, in moving away from the risks of excessive sunlight, societies have created new health challenges associated with inadequate sun exposure.

Conclusion

Sun therapy reflects a fascinating chapter in medical history where natural elements were harnessed as medicine, validated by a Nobel Prize, and later re-evaluated in light of modern science. While traditional heliotherapy is no longer widely practiced, its influence persists in contemporary phototherapy, offering safe and effective treatments under controlled conditions. The story of sun therapy underscores the evolving nature of medical practice, where initial enthusiasm, scientific innovation, and later risk assessment converge to shape how therapies are applied in modern healthcare.

Sae Hwalgi – “Renewed Energy”

The Path of Renewed Vitality and the Reality of Aging

In Korean martial arts and traditional language, expressions often carry layered meanings. One such expression is “Sae Hwalgi,” which literally translates to “new vitality” or “renewed energy.” At first glance, the phrase appears simple, but within martial instruction and holistic health contexts, it reflects both the natural vitality of youth and the inevitable decline of the body with age.

Linguistic Foundations

The phrase can be broken down into two key parts: Sae, meaning new or fresh, and hwalgi, meaning energy, vigor, or vitality (WordHippo, n.d.; Collins Dictionary, n.d.). In Korean everyday usage, hwalgi refers to liveliness and robustness, the spark of vigor that animates one’s daily life. In martial culture, however, the term also resonates with deeper energetic qualities, similar to the concept of qi (ki, or gi) – the life force that sustains movement and resilience.

Martial Perspective

For martial artists, aging creates a paradox. With experience comes wisdom, but with age comes loss of flexibility and suppleness. In youth, sae hwalgi manifests as hydrated tissues, supple joints, and rapid recovery. With age, however, connective tissues lose hydration, collagen stiffens, and movements that were once effortless become labored.

Research in connective tissue physiology supports this traditional observation. Studies have shown that aging reduces elastic fibers and hyaluronan content in muscles, while collagen type I increases, creating stiffness and functional decline (Fede et al., 2022). Martial masters may describe this process metaphorically as the loss of hwalgi, reminding practitioners that vitality is not permanent but must be cultivated.

The Science of Aging Tissues

From a biomedical perspective, hwalgi correlates with measurable changes in the body. Collagen loss, a systemic process associated with cellular aging, directly impacts tissue elasticity and hydration (Collagen loss, 2025). Fascia, the web of connective tissue supporting movement, is also profoundly affected by aging. Maintaining fascia through elastic training, hydration, and mobility work is crucial for sustaining vitality (Petersen, 2015).

These physical realities mirror what martial language describes: the transition from supple vitality (sae hwalgi) to diminished energy and rigidity as time passes.

Holistic Dimension

The decline of vitality is not purely physical. In holistic traditions, vitality depends on the balance of body, mind, and spirit. A calm, focused mind preserves energy, while a scattered or stressed mind depletes it. Similarly, qi depends on unobstructed circulation through meridians. Stress, stagnation, and aging create blockages that restrict this flow, contributing to both physical stiffness and mental fatigue.

Thus, sae hwalgi is not just a description of youthful elasticity but a call to action: to cultivate renewal of vitality through breath, awareness, and lifestyle practices that harmonize mind and body.

Renewal Practices: Cultivating Sae Hwalgi

While aging cannot be reversed, vitality can always be renewed in relative terms. Modern science and traditional practices converge on this principle. Ways to cultivate sae hwalgi include:

Breathwork – Deep diaphragmatic breathing regulates the autonomic nervous system and restores energy balance (Petersen, 2015).
Hydration and Nutrition – Adequate water and mineral intake support tissue elasticity (Fede et al., 2022).
Movement and Fascia Training – Martial forms, qigong, and mobility drills help fascia remain hydrated and resilient (Petersen, 2015).
Mental Clarity and Stress Management – Meditation prevents energy “leakage” and supports qi flow.
Adapting Martial Practice – Shifting from sheer force to refined technique preserves energy and allows martial arts to be practiced into old age (U.S. Kido Federation, 2024).

Conclusion

The wisdom of sae hwalgi lies in its dual nature. On one hand, it embodies the vigor of youth and the freshness of life’s energy. On the other, it acknowledges the inevitable loss of that vitality with age. Yet it is ultimately a hopeful concept. Through martial practice, breath, movement, and holistic awareness, vitality can be renewed at any stage of life.

For the martial artist, sae hwalgi is not a static state but a living reminder: though time may stiffen the body, the choice to renew vitality always remains.

The Power of Connection: Building a Life Beyond Suffering

From adolescence onward, many people witness the ways in which pain and suffering manifest in daily life. The young often see relatives struggle with chronic illnesses, neighbors burdened by poor health choices, and peers wrestling with emotional distress. Such early encounters plant seeds of awareness, where pain is unavoidable in the human journey, but suffering may be shaped, managed, and sometimes transformed.

The Path of Pain and Lifestyle Choices

Physical pain is often the result of neglecting foundational aspects of health such as nutrition, exercise, rest, and stress management. The body, a remarkably resilient organism, also has limits. When repeatedly deprived of balanced nourishment or consistent movement, it expresses its distress in the form of aches, fatigue, or chronic illness (Gaskin & Richard, 2012).

Modern societies exacerbate this reality by promoting convenience foods, sedentary work, and overstimulation. The cumulative effects are clear in rising rates of cardiovascular disease, diabetes, and musculoskeletal disorders. Such conditions create cycles of pain that can erode quality of life, often leading individuals to medical dependence rather than prevention. The lesson is that while pain may be unavoidable, much of it can be reduced or delayed through conscious lifestyle choices.

The Broader Dimension of Suffering

Yet suffering goes deeper than the body. Many people live with a sense of emptiness, disconnected from community and deprived of meaning. They may have food and shelter, yet suffer from emotional instability, loneliness, or lack of direction. This suffering often stems not from physical injury but from existential concerns of not knowing answers to questions of “Why am I here?” or “Does my life matter?” (Frankl, 2006).

Unlike pain, which often demands medical attention, suffering requires reflection, relationships, and a search for purpose. Without these, people drift into despair, self-destructive behaviors, or emotional volatility. Such suffering demonstrates that health is not only about the body but also about the mind, relationships, and spirit.

Loneliness and the Weight of Suffering

One of the most powerful drivers of suffering is loneliness. Being socially isolated not only worsens emotional health but also amplifies physical pain by magnifying stress responses and weakening resilience (Cacioppo & Patrick, 2008). Studies have shown that chronic loneliness can be as detrimental to health as smoking or obesity, leading to higher risks of depression, cardiovascular disease, and premature mortality (Holt-Lunstad et al., 2015).

Loneliness is particularly insidious because it often perpetuates itself. Those who feel isolated may withdraw further, avoiding opportunities to connect, which deepens their sense of separation. This cycle of isolation fuels suffering far beyond the body, affecting identity, hope, and self-worth.

Broken Hearts and Aging Connections

A striking example of how emotional suffering manifests in the body is “broken heart syndrome,” or stress-induced cardiomyopathy. This condition occurs when intense emotional distress, often from the loss of a spouse or loved one triggers severe, temporary heart dysfunction (Sato et al., 1990; Templin et al., 2015). The heart literally weakens under the weight of grief, illustrating the inseparable link between emotional suffering and physical health.

As people grow older, they often seek new or renewed connections to ease loneliness and sustain emotional well-being. Humans are inherently social creatures, and emotional relationships, whether with people or even pets, help fulfill this basic need. When a spouse or others that are close to us passes away or social networks shrink with age, individuals may experience profound loneliness, intensifying their suffering. In these cases, companionship becomes not a luxury but a lifeline.

Opportunities for older adults to engage in community activities, intergenerational groups, or pet companionship can reduce both emotional and physical suffering. These connections reinforce the truth that resilience and health are not maintained in isolation but in relationships.

The Shared Human Path

One universal truth is that everyone will encounter both pain and suffering. No one escapes illness, injury, or loss entirely. The recognition of this shared path can bring humility and compassion. Yet what differs among individuals is how they respond. Some choose avoidance, denial, or bitterness, while others confront pain and suffering with acceptance, resilience, and even gratitude.

The difference lies not in the inevitability of these experiences but in the interpretation of them. As Viktor Frankl (2006) observed, while suffering cannot always be avoided, it can be given meaning and through meaning, it can be endured. This insight has been confirmed in modern psychology, where resilience and purpose are linked to better coping with both pain and adversity (Ryff & Singer, 2008).

Lessons from Research and Tradition

Insights from long-term studies and cultural traditions further illuminate how pain and suffering can be softened through meaning, purpose, and connection.

The Harvard Grant Study

The Harvard Study of Adult Development, often referred to as the Grant Study, followed participants for more than 80 years initiated in 1938, making it one of the longest longitudinal studies on human well-being. Its most consistent finding was that close relationships are the strongest predictor of happiness and health, more important than wealth, social class, or even genetics (Vaillant, 2012; Waldinger & Schulz, 2010). Good relationships not only reduce emotional suffering but also protect against physical pain by lowering stress and inflammation over time.

Ikigai: A Japanese Path to Meaning

In Japan, the concept of ikigai, literally translated as “a reason for being,” captures the balance of what one loves, what one is good at, what the world needs, and what one can contribute to. Ikigai provides a framework for resilience by encouraging individuals to align their daily lives with purpose and community (García & Miralles, 2017). Those who cultivate ikigai often report lower levels of existential suffering and higher life satisfaction, even in the face of aging and physical decline.

Blue Zones and Longevity

Research into the world’s “Blue Zones” or regions where people live significantly longer than average, reveals strikingly similar themes. Whether in Okinawa (Japan), Sardinia (Italy), or Nicoya (Costa Rica), communities with the greatest longevity consistently share features such as strong social ties, daily movement, plant-rich diets, and clear purpose in life (Buettner, 2012). These factors not only extend lifespan but also reduce suffering by integrating meaning, belonging, and resilience into everyday living.

Together, these insights affirm that pain and suffering are not best addressed in isolation. Instead, they are mitigated by community, purpose, and the daily practices of gratitude and connection that strengthen resilience over a lifetime.

Epilogue: Gratitude and Encounters That Shape Us

Life is short, and its brevity underscores the importance of gratitude. To practice gratitude is to recognize the gifts already present, in our love, our friends, our memories, our knowledge, and hopefully our wisdom. Gratitude does not deny pain or suffering, but rather it balances them by highlighting what is still good and enduring.

Along the way, we meet people who, whether for a moment, a year, or a lifetime, shape our paths. Sometimes these encounters steer us in new directions, open our hearts to deeper compassion, or recalibrate our perspectives. Influence is not measured by duration but by depth. Each interaction becomes part of the mosaic of our lives, enriching our journey with meaning.

In this sense, gratitude and human connection soften suffering. They remind us that while pain is unavoidable, we need not endure it in isolation or despair. By appreciating what we have and valuing the people who cross our paths, we transform life’s hardships into opportunities for growth and renewal. What might seem fleeting in time can, in fact, echo across a lifetime as a source of guidance and strength.

A Call to Action: Choosing Connection and Meaning

The challenge before us is clear. Pain will touch every life, and suffering will knock on every door. Yet within that reality lies our freedom to choose how we respond. Each of us has the capacity to soften suffering, both in ourselves and in others, by building healthier habits, nurturing relationships, and seeking meaning in everyday life.

Take time to care for your body through movement, rest, and nourishment. Cultivate your mind through learning, reflection, and discipline. Strengthen your spirit by practicing gratitude and living with purpose. Most importantly, reach out to others, because connection is the antidote to isolation. Join a group, call a friend, volunteer, or simply open your heart to a neighbor.

If we each commit to these small but powerful choices, we not only transform our own experience of pain and suffering, but we also create ripples of compassion and resilience that extend into our families, communities, and beyond.

The gift of living is not just to endure but to grow, connect, and share. The time to begin is today.

Living Meditation: Bright Reflection in Taoist and East Asian Traditions

The Korean phrase Myung Sung literally translates as bright thought or clear reflection. In modern Korean, it is also the standard term for “meditation.” In English, the concept has been presented as Living Meditation, an embodied, everyday mindfulness woven into the fabric of ordinary life.

Although Myung Sung is distinctly Korean in name, its roots are Sino-Korean, derived from the Chinese characters 明 (ming, bright/clear) and 想 (xiang, thought/reflection). Comparable ideas appear across East Asian traditions: in Chinese Taoism, alignment with the Dao emphasizes clarity and flow; In Japanese, Meisō is the most direct equivalent, while Ichigyō Zanmai describes being fully absorbed in a single activity, similar to the idea of “Living Meditation.” Thus, “Living Meditation” is not confined to one culture, it is a shared practice of engaging fully and harmoniously with life.

This article critically examines the guiding principles of Living Meditation (Myung Sung), situating them within Taoist philosophy, Zen practice, and modern mindfulness research.

Taoist and Cultural Foundations of Living Meditation

Taoist philosophy views life as an ongoing process of aligning with the Tao, or the natural order of the universe. The Tao emphasizes balance, spontaneity, and effortless action (wu wei) (Kohn, 2020). In Korea, these ideas merged with Confucian ethics and Buddhist practices, producing unique expressions such as Myung Sung. In Japan, Zen Buddhism developed a parallel emphasis on mindfulness in daily activities, from tea ceremonies to martial arts (Suzuki, 1956).

The literal meaning of Myung Sung being “bright reflection” captures the essence of Taoist and Zen practice: illuminating the mind, clarifying perception, and cultivating awareness moment by moment. By viewing meditation as an active, daily process, Living Meditation stands apart from traditions that encourage withdrawal from worldly concerns. Instead, it insists that clarity, harmony, and enlightenment are found in the midst of life.

Mindfulness and Living Meditation

Western psychology defines mindfulness as “moment-to-moment awareness of one’s experience without judgment” (Kabat-Zinn, 2015, p. 148). Myung Sung aligns with this definition but extends it. Rather than being limited to seated practice, it emphasizes that every action, from working to communicating to parenting, can become an act of mindful clarity.

This mirrors Taoist teaching on yin-yang balance and Zen’s shikan taza (“just sitting”), but it goes further in emphasizing relational legacy. Myung Sung asks not only how one lives in the present, but also what seeds of goodness and compassion one leaves for future generations. This collectivist orientation aligns with East Asian traditions of intergenerational responsibility (Li, 2007).

Developments in mindfulness research indicate that these interventions can be successfully adapted to diverse environments, including schools, workplaces, clinical settings, prisons, and military contexts, confirming their wide applicability in contemporary society (Creswell, 2016).

The Eight Principles of Living Meditation

1. Know Your True Self

Self-awareness is described as the foundation of all growth. To know the “true self” is to recognize both the visible and invisible aspects of being. Taoism encourages similar introspection, while Zen uses the term kenshō (“seeing one’s true nature”) to describe this realization.

2. The True-Right-Correct Method

Decision-making is guided by balancing the true (inner feelings), the right (socially beneficial actions), and the correct (harmonious integration of both). This echoes Taoist ethics of balance and the Confucian Doctrine of the Mean (zhongyong).

3. Stop Being Drunk on Your Own Thoughts

In Korean, the phrase Doe Chi literally means to be “drunk on” something or caught up, clouded, and overly attached to one’s own mental noise. This principle warns against excessive attachment to rigid beliefs. Taoism also cautions against clinging to fixed ideas, while Zen emphasizes detachment from discursive thinking.

4. How Will You Be Remembered?

Legacy is framed as the planting of seeds for future generations. Confucian philosophy similarly stresses filial piety and the continuation of virtue across time.

5. Seek Connectedness and Honor

All beings are interrelated, and honor means living with respect, integrity, and compassion. Taoist cosmology views humans as part of a larger web of qi (vital energy), while Confucian ren emphasizes relational humaneness.

6. Change Your Reality for the Better

Living Meditation insists that inner states shape external realities. Taoist practice of aligning qi with the environment parallels this principle, while modern psychology recognizes the transformative power of reframing thought patterns (Beck, 2011).

7. It Only Takes One Match to Light a Thousand

Small actions produce ripple effects. Taoist yin-yang dynamics and Zen karmic teachings both affirm that even minor choices influence larger outcomes.

8. Be Like Bamboo

Bamboo, strong yet flexible, symbolizes resilience. Taoist writings and Zen poetry both use natural metaphors to highlight adaptability, balance, and endurance.

The Three Pillars: Meditation, Medicine, and Movement

Living Meditation is supported by three interconnected practices:

Meditation – continuous mindfulness integrated into daily activity.
Medicine – natural remedies and holistic care, paralleling Chinese and Japanese traditional medicine.
Movement – practices such as Qigong, Tai Chi, or martial arts, uniting body, mind, and spirit.

These three dimensions resemble integrative health frameworks that modern medicine increasingly recognizes (Rakel, 2017).

Conclusion

Though the term Myung Sung originates in Korea and literally means “bright reflection,” its essence transcends culture. Chinese Taoism calls for clarity and balance through the Tao; Japanese Zen offers expressions such as meisō, ichigyō zanmai, and kenshō. English captures it as “Living Meditation,” underscoring its practical, everyday application.

Across languages and traditions, the message is consistent: meditation is not withdrawal from life but illumination within it. By practicing Living Meditation, individuals cultivate clarity, resilience, compassion, and legacy becoming, in essence, living embodiments of bright reflection.

Kung – Mudo – Budo

Three Martial Worlds, One Shared Philosophy

Across East Asia, the martial arts are far more than systems of combat. In their deepest form, they are paths of personal transformation that unify physical skill, mental discipline, and moral responsibility. While each culture frames this idea differently, the underlying message is consistent: mastery of technique is inseparable from mastery of self.

In China, this idea finds expression in the concept of Kung (功), the refined skill and capability gained through sustained effort, whether in martial arts or any other discipline. Kung is not simply physical power; it is the culmination of patient, deliberate cultivation of mind and body over years or decades.

In Korea, the term Mudo (무도), literally “The Martial Way,” places emphasis on the journey of training. It describes a life lived according to the values and discipline of martial practice, with skill as the natural outcome of a moral and dedicated path.

In Japan, Budo (武道), also “The Martial Way,” draws from Bushido, Zen, and Shinto traditions. It frames martial training as a lifelong spiritual and ethical endeavor, where combat proficiency is a vehicle for self-perfection and service to others.

While the terminology and historical contexts differ, Kung, Mudo, and Budo all hold to a shared truth: martial arts are not solely about defeating an opponent, but about shaping character, nurturing wisdom, and aligning one’s actions with a higher ethical standard.

Kung vs. Mudo vs. Budo

Kung (功) in the Chinese Context

In Kung Fu: History, Philosophy and Technique, (Chow, 1978) Kung (功) refers to skill acquired through hard, disciplined effort, especially in the martial arts.

In this context, it’s about the internal and external mastery that results from persistent training, including moral discipline, mental focus, and physical conditioning.

While it’s rooted in Chinese martial culture, it’s not limited to combat; Kung can apply to any art or craft perfected over years of dedicated practice.

It emphasizes process and cultivation, not just end results.

Mudo (무도) in the Korean Context

Mudo literally means “Martial Way” (武道) — mu (무, 武) = martial/military; do (도, 道) = path/way.

It is a broader ethical and philosophical concept, referring to martial practice as a path of personal development, much like Budo in Japan.

Mudo includes:

Physical discipline (techniques, forms, application)
Moral integrity (using skill responsibly, respect for life)
Character development (patience, humility, perseverance)

In Korean martial traditions (Hapkido, Taekwondo, traditional sword arts), Mudo is both a lifestyle and a moral code.

Budo (武道) in the Japanese Context

Budo literally means “Martial Way” — bu (武) = martial/warrior; do (道) = path/way.

It represents the unification of martial training with moral character and spiritual refinement, drawing from the traditions of Bushido, Zen, and Shinto philosophy.

Budo includes:

Mastery of martial technique (kenjutsu, judo, aikido, kendo, karate, and others)
Ethical conduct (honor, integrity, respect for life)
Personal growth and self-discipline as lifelong endeavors

In Japanese tradition, budo is as much about cultivating the spirit and serving society as it is about combat skill. It treats martial practice as a lifelong path toward self-perfection.

Where They Overlap

Kung, Mudo, and Budo each frame martial arts as a lifelong practice that refines mind, body, and spirit.

All three require ethical restraint, or the principle that skill is to be used justly, never recklessly.

All three value internal development as much as technical proficiency, seeing martial arts as a vehicle for character formation as well as self-defense.

In practice, a master of Kung, a practitioner living by Mudo, and a devotee of Budo would share similar daily disciplines, values, and moral outlooks.

Key Differences

Kung emphasizes effort and skill mastery as the result of disciplined training.
Mudo emphasizes the path and philosophy as a journey of living according to martial ethics.
Budo emphasizes harmonizing martial skills with moral character as the way of the warrior in service to self and others.

Kung is what a practitioner has after years of training.
Mudo is how a practitioner lives while they train.
Budo is how a practitioner walks the path, using martial skill to perfect the self and serve a greater purpose.

The following chart explores the philosophical, linguistic, and cultural parallels between these three concepts, revealing their unique nuances and shared spirit.
