Vitamin D levels relate to mortality
If you were a bookworm or otherwise inclined to stay inside when you were a kid, your mom may have yelled at you to get outside and play. Turns out she was right--that being outside is literally good for your health.
Vitamin D, that elusive nutrient that's only available from sunshine and from vitamin supplements, seems to play a significant role in death rates. A study shows people tend to die sooner from all causes when their vitamin D is lower than accepted levels. How's that for a powerful reinforcement of your mom's prescription!
Plus, I read the other day about a test comparing how students' hearts behaved while doing an assignment and viewing either a) a blank wall, or b) a video screen showing a nature scene, or c) an actual window onto the same natural scene. Guess what? The only situation that proved favorable to the students' hearts was viewing the real natural scene.
So with the impending holiday weekend ahead, it's good advice to take to heart. Getting outside's good for it.

Apparently, doctors can check your vitamin D levels with a blood test. Also, I've read that it's almost impossible for people in North America, especially those of us in the more northern parts, to get adequate amounts of vitamin D via sunlight.
I guess we need to take supplements.
Yeah, I used to be a big pooh-pooher of vitamins, but all the reading I'm doing for BioMedNews is convincting me otherwise. One of the most critical pieces in that puzzle for me was a report I read some time ago that reported that our vegetables have lost 40% of their nutritional value over the last decades. Depressing. But I know our scientists will get on that one soon, too.
sorry for the typo - meant "convincing"
