Getting sun exposure without sunscreen is important for vitamin D production from "summary" of The Vitamin D Solution by Michael F. Holick Ph.D., M.D.
It is well known that exposure to sunlight is essential for the production of vitamin D in our bodies. When our skin is exposed to sunlight, it produces vitamin D in a process that starts with the conversion of a cholesterol derivative in the skin to previtamin D3. This previtamin D3 is then converted to vitamin D3, which is also known as cholecalciferol. This production of vitamin D is crucial for our overall health and well-being. Vitamin D is needed for the absorption of calcium and phosphorus in the intestines, which is essential for maintaining strong and healthy bones. It also plays a critical role in regulating the immune system and reducing inflammation in the body. However, in today's world, many people are not getting enough sun exposure due to various reasons such as spending more time indoors, using sunscreen, or living in areas with limited sunlight. While it is important to protect our skin from the harmful effects of UV radiation by using sunscreen, it is also important to strike a balance and get some sun exposure without sunscreen to allow for the production of vitamin D. It is recommended to spend some time in the sun without sunscreen for about 10 to 15 minutes a few times a week to allow for the production of vitamin D. The amount of sun exposure needed varies depending on factors such as skin type, time of day, season, and geographical location. People with darker skin may need more sun exposure compared to those with lighter skin to produce the same amount of vitamin D.- Getting sun exposure without sunscreen is important for vitamin D production, which is essential for our overall health. It is crucial to strike a balance between protecting our skin from the harmful effects of UV radiation and allowing for the production of vitamin D by spending some time in the sun without sunscreen.
