Medical studies show that moderate exposure to sunlight is crucial for the maintenance of good physical and psychological health. In fact, for most people, it may be riskier to avoid sunlight than to tan moderately, according to new research.
UV-B rays are the main source of Vitamin D for our bodies, which helps to promote healthy bones and the absorption of calcium and phosphorous in the body. Sunlight is the body’s only natural and reliable source of Vitamin D. Studies suggest that this vitamin – linked to the prevention of breast, colon, prostate and ovarian cancers – cannot be reliably supplemented in our diet.
Exposure to sunlight may have similar effects as exercise; decreased blood pressure, lower resting heart rate, a 39% increase in the output of blood. UV light is also known to help breakdown cholesterol.
70% of patients with Seasonal Affective Disorder (SAD) show improvement after UV treatment, the only known cure for the “winter blues”.
Sunlight stimulates the thyroid gland, which boosts your metabolism.
Because UV exposure produces Vitamin D which helps in the absorption of calcium into bones, you could decrease your risk of developing osteoporosis.
Many types of cancer – including breast, colon, prostate and ovarian – are slowed or inhibited by maintain proper Vitamin D levels. More than 138,000 Americans die each year from breast, colon, ovarian and prostate cancers. One 1993 study claims that the wide spread public adoption of regular, moderate sun exposure could prevent 30,000 breast and colon cancer deaths each year.
Ten minutes of exposure to ultraviolet light 1-3 times per week reduces the frequency of colds up to 40.3%.
