Studies on the benefits of safe and optimal amount of sun exposure include:
More Vitamin D
Did you know Vitamin D deficiency is now recognized as a pandemic? Sun exposure in moderation is the major source of vitamin D for most humans.
Body odour reduction and disinfection
Vitamin D may prevent daytime sleepiness. According to research, patients with daytime sleepiness and musculoskeletal pain are likely to have vitamin D insufficiency or deficiency.
Reduced symptoms of multiple sclerosis
Ultraviolet B radiation, like that in sunlight or low pressure tanning bulbs, suppresses inflammation and disease progression of multiple sclerosis (MS).
Decrease melanoma mortality risk
Studies show melanoma mortality actually decreases after UV exposure. Melanoma lesions do not predominate sun-exposed skin, which is why sunscreens have proven ineffective in preventing it. Exposure to sunlight, particularly UVB, produces vitamin D in your body, which is protective against melanoma.
Nitric oxide produced by UV exposure is responsible for the prevention of the detrimental effects of too much UV.
Prevent heart disease and stroke
When sunlight touches your skin, nitric oxide, a powerful blood pressure lowering compound, is released into your bloodstream.
Boost immune system and brain function
Vitamin D is intimately involved not only in immune system function, but also brain function. It appears that vitamin D has protective effects and immunomodulatory effects in the brain, and is useful in neurodegenerative and neuroimmune diseases, typified by MS.
Reduce breast cancer risk
Optimized Vitamin D Levels can reduce breast cancer risk by 77% over a 4 year period according to a study published in 2007 in the American Journal of Clinical Nutrition.
Recent studies have shown that UVA exposure reduces morning stiffness, fatigue, joint tenderness, joint swelling and increase grip strength in rheumatoid arthritis sufferers. Also, UVB is associated with a reduced risk of RA.
