I have had vitamin D deficiency (17 ng/mL) and I am planning on sitting in sun at noons. I am aware of that how much UVB you get depends on a few factors such as your complexion, where you live and even the clothes you wear. I know sitting in sun in hot climates can cause sunburn and skin cancer.
The season is winter where I live now. The temperature is around 10 degree celsius but the weather is sunny.
What I was wondering is that if I can beat the vitamin D deficiency in a week if I sit in sun regularly for a few hours for a week.
I know that deficiencies may take for months to return in normal levels such as iron deficiency and you should take a certain amount of it for everyday. However, as for Vitamin D, I read our bodies can accumulate vitamin D in summer times for winter times. Therefore, for my situation, how many days would it take to get to normal level if I sit for long hours regularly in sun.
