Regular exposure to the outdoors and sunlight is healthy.
Cancer protection is an integral part of the benefits of sun exposure. Epidemiological studies prove sunlight exposure lowers the risk of colon-, breast-, prostate cancer, non-Hodgkin lymphoma, multiple sclerosis, hypertension and diabetes!
While there are benefits that are linked to levels of Vitamin D, which are directly related in the young and middleaged individuals to sun, these beneficial effects are not just due to vitamin D.
Recently it became evident that immune system changes and many other compounds are responsible for the beneficial effects of sunlight.
Health benefits of the sun extend to the levels in our body of nitric oxide, melatonin, serotonin, and the effect of sun and light on our biological or circadian clock.
The topic is complex, research is evolving, and we do still suggest that appropriate sun protection including the medical grade sunscreens we offer prevents skin cancer. I myself enjoy Garden Yoga in the sun at Hattah Yoga and Fitness, whenver I can!
