Prevention of certain cancers, improved cardiovascular system, bone growth ... a reasonable exposure is beneficial to health.
The sun, that's life. And although it can be dangerous, you have to take advantage of its enormous energy.

Visible light helps to sleep well and to keep morale

This radiation is just one that sheds light during the day. But beyond their role as huge bulb, the sun and its visible light regulates our metabolism.
Indeed, the visible light enters the eye by our body, passes through the optic nerve and reaches the brain. It thereby increases the production of melatonin, sleep hormone, which is involved in the regulation of our metabolism.
Thus, sufficient exposure to visible light from the sun can spend a day in great shape and sleep well at night.It has also been shown that visible light had a beneficial effect on our morale.

Ultraviolet rays help strengthen bones

UV is not dangerous if it does not expose too long (otherwise they may be responsible for an increased risk of skin cancer and cataracts).
They allow in particular the synthesis of vitamin D which fixes the calcium on bones. Without UV, the risk of osteoporosis is much larger, our bones are not as strong and therefore would break much more easily.

Cancers, cardiovascular system, hypertension, ... recent research has highlighted other benefits, still poorly understood, the sun.

Proper exposure to sunlight would reduce the risk of breast, colon and prostate. Unfortunately, researchers do not yet know the mechanism associated with this reduction in risk.
A study published in the Journal of Investigative Dermatology also shared the benefits of the sun on the cardiovascular system. According to this study, exposure to the sun about 30 minutes decrease the risk of cardiovascular disease by lowering blood pressure. UVA rays are the cause of these benefits. They would increase the nitric oxide levels in our skin, which would have the effect of expanding blood vessels, preventing high blood pressure and cardiovascular diseases that follow.
