The most important function of Vitamin D is that it promotes the absorption of calcium which is essential for strong bones and teeth. Without sufficient vitamin D bones become porous also known as osteoporosis which increases the risk of fractures.  

Other symptoms of vitamin D deficiency include muscles weakness, body pain & excessive hair fall. Therefore it is very essential to maintain normal level of Vitamin D and we all know that the best source of Vitamin D is sun.

The body is able to synthesis vitamin D when ultraviolet radiation from the sun hits the naked skin without any SPF (sun protection factor). But most of us don’t want to go out in the hot sun due to fear of getting skin cancer. But studies have found that the best time to get Vitamin D without risk of getting skin cancer is noon i.e. 11am and 2pm. Spending even 15-20 minutes of time at this time interval can provide the body sufficient vitamin D all year round.
