Normally the back and forth of "It's going to kill us all!" and "No, it's fantastic for us!" usually stays in the realm of caffeine, red meat and the films of Nicolas Cage. If there's one thing that the consensus has seemed to be: well, you need more of it, otherwise you have no clue how screwed you are--it's sleep.
Lack of sleep has been blamed for everything from diabetes to reality television, and that's some finger-pointing that does make sense. If you're tired, then you're probably stressed. And if you're stressed, then your body releases all those lovely "We Could Be Eaten By Something" chemicals...and too much of that can be quite bad. Especially if you're not actually being Eaten By Something.
Good news? Perhaps. Now if we can just figure out the best position to sleep in. Because that apparently could kill us too. Sigh.
