The question of how much sunlight you should get each day is a difficult one to answer. There are considerations like:
- Time of day
- Time of year
- Ethnic background/skin color
- Liver health
The World Health Organization recommends 10-15 minutes for three times per week and avoiding the sun between the hours of 11am-3pm each day.
Unfortunately, this info does not match up with the extensive research and data collect in scientific study. When reviewing the considerations listed above, it is impossible to generalize the amount of sunlight required to keep over 7 billion people across the planet healthy.
