I did pretty well yesterday because I had to water the flowers in my yard. Probably about an hour of direct sunlight altogether. It is important to get some sunlight, so your body creates Vitamin D. See my hub on Vitamin D for more details.
We had a sunny day yesterday-yeah! not much summer in the Fraser Valley. I was outside for about half an hour. that's the most I'll ghave of direct sunlight if I can help it. Usually I am for twenty minutes. If I am going to be out there for longer I make sure I am well covered.
Got only two hours of direct silent.woke early and back home at night but 2hours is enough to get vitamin D. Sun exposure(Vit. D) is necessary which also stimulate the calcium level in bone to prevent certain disease like bone abnormalities such as rickets and osteomalacia
