Sunlight is regarded as the main source of energy which allows plants to grow. They convert sunlight into chemical energy essential for their survival.

Even though the sun carries ultraviolet rays which can damage human skin, cause sunburn and can potentially cause skin cancer, it is also helpful in fighting numerous infectious diseases in the human body, according to a report from USA Today.
Sun is also a source of one of the 13 essential vitamins — Vitamin D — necessary for a healthy human body.
Why is Vitamin D important?
When the human body is exposed to sunlight, it starts chemical reactions and helps our body to produce Vitamin D, according to Harvard Health Publishing.
The converted energy into chemicals then hydroxylated in the liver and kidneys to be ready for vitamin D, mentioned the National Institutes of Health’s (NIH) Office of Dietary Supplements.

In children, it causes now-rare bone diseases, and in adults causes osteomalacia or osteoporosis, mentioned Harvard Health Publishing.
The risk of Vitamin D deficiency is high in nonwhite people as pigmentation could affect of the production of Vitamin D in the skin.
The rich sources of vitamin D are fatty fish, liver and fortified foods to their diets, according to Harvard’s T.H. Chan School of Public Health.
Orange juice and milk are also good sources of this Vitamin.
According to the suggestions by Mayo Clinic, those who are unable to get a Vitamin-rich diet and enough sunlight can take Vitamin D supplements to meet the requirement.
However, the overdose of Vitamin D can cause calcium levels to increase in the blood leading to nausea, dehydration, abdominal pain, confusion and more, according to Healthline.
