Sunscreen forbidden at schools and camps

It sure would be nice if common sense could rule the day. Moderation is the key - it used to be that we never put on sunscreen, then cancer fears spurred authorities to say we need to slather it on Every Time we went outside for longer than 15min. Then they started realizing that people were suffering from too low of levels of Vitamin D because they had sunscreen on so much of the time that our bodies couldn't manufacture enough (Vit D is really difficult to get into our systems orally). Not enough Vitamin D means our bodies can't absorb and utilize calcium well enough.

What needs to happen is for people to get sun naturally for a while each day, then put sunscreen on to protect themselves after that. It's ridiculous to consider sunscreen an over-the-counter medicine (it's applied externally and not absorbed into our systems).

I can understand the issue about the hats. Simple solution, they can bring them to school, but they are only allowed to wear them when they go outside. I'm sure it's not this way at all middle schools and high schools (the ages when gangs are really the problem) across the country, but at mine, we didn't have outside time during the day at all, and only half an hour in middle school if it was nice enough out. So needing hats was a minimal concern.

Logic and rational thinking, please prevail!
