Daily Sunlight
Sunlight is vital for all life on this planet. It plays a vital role in the circadian rhythms of the Earth, is necessary for photosynthesis in plants (to make possible the plant growth and the resulting food chain), and is one of the most effective disinfectants known to man (hence the use of UV light for water purification).

Health Benefits Of Sunlight

While darkness increases melatonin and serotonin, much of the serotonin is converted to melatonin. Sunlight on the other hand, suppresses melatonin production, while increasing the body's production of melanin, serotonin, Vitamin D and endorphins. Sunlight helps balance PH, stimulates and regulates the immune system (thereby reducing susceptibility to infections and autoimmune disorders), improves detoxification via lymphatic, digestive and dermal systems, improves and supports cardiovascular, skeletal, muscular, digestive, nervous and reproductive health. Balance between darkness and light, melatonin and serotonin improves general mental and emotional health, strengthens endocrine, immune, nervous and reproductive systems, helps regulate sleep cycles, appetite, body weight and metabolism, helps the body to produce and balance hormones and other body chemicals.

Daily Sunlight Requirements

Generally, 10 to 30 minutes of sunlight exposure each day is sufficient. Though excess sunlight can cause the body to produce free radicals, antioxidants (such as Vitamin D, which is produced by the body in response to sunlight) and melanin (which again, is produced by the body in response to sunlight) offset this by reducing the free radicals produced. Excess sunlight can also cause dehydration, sunburns and wrinkles, yet excessive sunlight exposure is unlikely to cause cancer. Toxic chemicals in sunscreens, tanning lotions or oils, cosmetics and other commercial personal hygiene products are actually more likely to cause skin cancer than exccess sunlight. Sunlight in fact, helps prevent skin cancer, by increasing the body's production of Vitamin D and melanin.
