The magnificent sun, UV, and what they do for our bodies and minds. Embrace the Sun!

Health benefits of UV by Marc Sorenson, Ed.D.

How important is UV? Sunlight. UV heart and mindA transcendentally important scientific paper, by Dr. AT Slominski and colleagues, has added significant information about UV (sunlight) for skin. In addition, it explains the intricate connection between sunlight and the immune, endocrine and central nervous systems.[1] The name of the research paper, published in the journal Endocrinology, is How ultraviolet light touches the brain and endocrine system through skin, and why. The authors begin the abstract by stating that “the skin is a self-regulating protective barrier organ that is empowered with sensory and computing capabilities to counteract the environmental stressors to maintain/restore disrupted cutaneous homeostasis.” In other words, the skin has the ability to take on what life deals it and maintain its equilibrium and balance. In addition, the skin communicates bidirectionally with the central nervous, endocrine and immune systems. Thus, it helps to maintain balance for all body systems.

How does UV work?

First of all, ultraviolet energy (UV and UVB light) triggers all of these marvelous processes. UV, of course is available from sunlight, sunbeds or sunlamps. Its electromagnetic energy, through the skin, converts to chemical, hormonal and neural signals. These signals promote positive effects on the immune system, the endocrine system and the brain. Furthermore, endorphins (opioid-like substances) are increased and immune-system proteins are mobilized; consequently, health improves with UV. And, sun exposure regulates the endocrine system, by way of exposure to the skin, to produce or diminish hormones as needed. Especially relevant is that these effects take place independently of vitamin D synthesis.

Health increases with UV due to the magnificent sun, and our magnificent skin. As a result of the above information, it seems like it would be a good idea to soak up some non-burning sun each day when available. And, when it is not, we should find another UV source. In our soon-to-be-published book, Embrace the Sun, we discuss many facts about the healthful effects sun exposure:

A few healthful effects of sun (UV) exposure

  • prevents and reverses obesity
  • Improves longevity by reducing the risk of death by 50% over 20 years
  • reduces the risk of hip fracture by 90% when compared to sun avoidance
  • prevents the risk of breast cancer by 90% when compared to sun avoidance
  • reduces by 50% the risk of melanoma in outdoor workers compared with indoor workers
  • increases heart and vascular strength
  • dramatically improves mood
  • reduces the risk of multiple sclerosis
  • reduces risk of most internal cancers
  • cures psoriasis and eczema
  • reduces risk of nervous system disorders
  • prevents memory loss
  • prevents myopia

The above list is not surprising in view of this new research, nor is the list complete. UV has many more healthful effects, which I’m sure the authors of this research acknowledge. Hence, the scientists sum up their research in this manner: “Thus, UV touches the brain and central neuroendocrine system to reset body homeostasis. This invites multiple therapeutic applications of UV radiation, for example in the management of autoimmune and mood disorders, addiction, and obesity.”

In conclusion, this seem like more compelling evidence to safely embrace the sun, no?
