Sunlight is a naturally occurring source of vitamin D, a vital nutrient that plays a number of important roles in retaining good health. When exposed to UV rays from sunlight, a chemical reaction takes place in our skin cells, evolving in the production of vitamin D3, which is also known as cholecalciferol.

Vitamin D assists in regulating calcium absorption and stimulates bone growth, making it a necessity for retaining strong and healthy bones and staying away from osteoporosis. It also helps the immune system function by stimulating antimicrobial proteins that help in dropping off infections. Furthermore, investigation also suggests that appropriate levels of vitamin D is important as it may lessen the risk of chronic illnesses such as cardiac diseases and certain types of cancer.

It is suggested by professionals to take some time from your busy schedule during peak hours and give your skin exposure to the sunlight when UVB radiation is the highest, mostly between 10am and 3pm, to seek benefits from sunlight without building the risk of skin cancer or premature ageing.
