Vitamin D and Kids: How Much Sun Should They Get to Stay Healthy?

Federal data shows that more American children are lacking in vitamin D because of more time spent indoors on video games and computers; less milk; and sunscreen. A senior author of the study recommends 10 to 15 minutes a day in the sun without sunscreen for children who can handle it. Drinking more milk and orange juice fortified with vitamin D and possibly vitamin supplements might be in order. The National Academy of Sciences is discussing the value of vitamin D. This article has links to other studies and value of sunscreens.

Lesson: Students at schools where recesses have been take away due to concerns over low testing scores should research more about the lack of vitamin D in kids. After investigating daily habits of kids diet, exercise, and sun time, students could create an ideal routine for diet, exercise, and sun exposure. Next they would write letters to the school administration and the local news media giving the reasons for the value of recess for exercise and sun exposure.
