<h2>Time Spent Under Sun In Summers Could Get You Through Winters</h2>

Vitamin D has unique characters that makes it different from vitamin C, another popular supplements. It is a steroid that acts as a hormone in the body and is one of the fat-soluble vitamin. This means, it could be stored in fat and muscles, that too for a relatively long time, says Herrmann.

People who spent a lot of time outdoors in summers only begin to deplete their vitamin D levels in February, which is almost the end of winters. Even after this, a few hours a week in fresh air and winter sunlight is enough to produce sufficient vitamin D again. 

However, experts point out that because vitamin D is stored, this is what makes it difficult to be excreted, especially when the doses are high. It remains in the body and could harm the person.
