And before you go running for the sun, that may not necessarily be the cure. The weather is warming up, the days are getting longer and even though we are spending more time outdoors, doctors still say it isn't enough.
More than 42% of Americans are not getting enough of the vitamin that our skin produces from sunlight, a 2011 medical study "Prevalence of vitamin D deficiency" found.About two-thirds of the U.S.
doesn’t even get enough sun during most months to supply the necessary amount of vitamin D. North of the 37th parallel, people only get enough sun for skin to make the amount of vitamin D needed during the summer, according to a research article, "Time for more vitamin D".
