Vitamin D is a Sun-Shine

Our body produces vitamin D after absorbing the sun’s rays. But if you are thinking that you are consuming sunlight from inside the window in a closed house, then there will be no shortage of Vitamin D, then you are totally wrong. According to science, “Your body makes vitamin D when your bare skin is exposed to the sun.” Additionally, clouds, smog, old age, and dark-colored skin reduce vitamin D production. 

It’s recommended to get sun exposure for 10 to 15 minutes every day or at least three times a week.
