Vitamin D, sunbathing and sun protection
Vitamin D is crucial to stay healthy. We all know it spurs bone growth and insufficient level of vitamin D can therefore trigger osteoporosis. It is also a fuel to boost our immune system and highly protective for a lot of diseases.
Every day sun exposure and safe sunbathing can help to avoid Vitamin D deficiency. When you are exposed to sunlight the skin manufactures vitamin D because the sun’s ultraviolet B (UVB) rays interact with a protein called 7-DHC in the skin, converting it into vitamin D3, the active form of vitamin D.
The key points are ‘healthy’ and ‘safe’ exposure to sunlight. Too many people think the use of sunscreens lead to Vitamin D insufficiency.
Studies have never found this. This is because no matter how much sunscreen you use, some of the sun’s UV rays will reach the skin. An SPF 15 sunscreen for example, filters out 93 percent of UVB rays, SPF 30 keeps out 97 percent, …. This leaves anywhere a fair percent of solar UVB reaching the skin and triggering 7-DHC conversion to Vit. D3. In fact, recent studies show that people who use sunscreen daily can maintain their vitamin D levels.
Sun exposure is important nevertheless you have not to take the deadly risks of unprotected sun exposure to ensure a right provision.
Tanorexia is the definition of an obsessive desire to acquire and maintain a suntan by natural or artificial method.
