Keep in mind sun that is filtered through glass does not have very strong UVB rays, so getting sun indoors behind a window will not give you necessary amount of exposure to the sun.Try to still spend time outside during the winter months, even if it is cold outside. In the winter time, it can be more difficult to get five to 30 minutes of sun on your face and arms.However, factors like the season, the time of day, the amount of cloud cover, air pollution, and the melanin content in your skin can affect your body’s ability to absorb vitamin D. Your location on the planet, such as your latitude, doesn’t make a significant difference in terms of the amount of UVB rays you are getting when you sit out in the sun.Do this at least twice a week and try to expose your face, arms, legs, and back to the sun.

To stimulate this process, you should spend five to 30 minutes in the sun without sunscreen between 10 in the morning and three in the afternoon. Your skin cells are stimulated to make vitamin D after they are exposed to ultraviolet B (UVB) rays from the sun. Spend five to 30 minutes outside in the sun between 10 am and three pm.
