When your skin is directly exposed to the sunlight, without any sunblock, your body produces Vitamin D when UVB rays hit the cholesterol in the skin, creating sufficient energy to synthesize Vitamin D.
But this does not mean that you should expose yourself to the sun for long because this can be harmful to your skin. For your body to have good stores of Vitamin D, exposure to an adequate amount of UVB rays is necessary. It is estimated that during summer, mid-day is the best time you can get sunlight because the sun reaches its highest point at noon and emits more intense rays.
Moreover, the color of the skin also determines the amount of vitamin D produced. Melanin, which is produced when the skin is exposed to UVB rays of the sun, is present in large amounts in dark-skinned people. This protects the skin by absorbing fewer amounts of rays.?Therefore, dark-skinned people need more time in sunlight to make a specific amount of vitamin D as compared to lighter-skinned people.
