Vitamin D is metabolized in the skin by keratinocytes. These are skin cells that process keratin, a protein in hair, nails, and skin. When the body doesn't have enough vitamin D, keratinocytes in hair follicles have trouble regulating hair growth and shedding.
This lead us to conclude that for optimal vitamin D synthesis at minimal risk of cutaneous malignant melanoma (CMM), the best time for sun exposure is between 10 a.m. and 1 p.m. Thus, the common health recommendation (that sun exposure should be avoided between the hours of 10 a.m. and 4 p.m. and postponed to the ...

At the equator, it would take approximately 24.5 Earth days while at the poles about 34 Earth days. One can also factor in time dilation, as one day on Earth (86,400 seconds) would be one day plus some change (86,400.2 seconds) on the Sun due to the fact that the Sun is much more massive than the Earth.
The Food and Drug Administration (FDA) recommended 1,000 IUs of vitamin D daily, which is equivalent to 10-15 minutes of sun exposure. Intervals amounting to 10-15 minutes of sun exposure every day may give you sufficient vitamin D, not only for skin health but overall health.
