Researchers have started recognizing the importance of sunlight for a healthy lifestyle, recent studies reveal that sunlight renders many health benefits. Apart from Sunlight maintaining temperature and humidity, sunlight plays a significant role in nourishing and energizing the human body. It is also vital in order to get the full nutritional value from food that you consume and it has been proven that getting sufficient sunlight aids in preventing chronic ailments such as seasonal affective disorder (SAD), osteoporosis, mental depression, type 2 diabetes, and cancers affecting the bladder, breasts, cervix, colon, ovaries, prostrate, and the stomach. To put it more succinctly, sunlight serves as the perfect medicinal pill in promoting a healthy lifestyle.

One of the prime benefits of sunlight is that it supplies the body with Vitamin D, which not only promotes the absorption of calcium in the gut but also transfers calcium across the cell membranes. This in turn provides strength to the bones as well as contributes for a healthy nervous system by increasing the production of endorphins in the brain. Usually, deposits of cholesterol-like substances known as ergosterol can be found beneath the skin, which gets converted into Vitamin D hormones when the sunlight penetrates the skin.

Vitamin D also helps to lower the level of cholesterol in blood, and sunlight can even prevent the growth of cancerous tumors. Studies show that exposing your face to sunlight for 10 minutes every day can provide your body with the Vitamin D that is required for the day. A lack of Vitamin D is associated with a host of autoimmune ailments such as Crohn’s disease, multiple sclerosis, rheumatoid arthritis, and thyroditis.
