The Need to Sleep

REPOSTED from Exchange Everyday
The Need to Sleep
November 29, 2012

Never apologize. Never explain. Just get the thing done, and let them howl.
-Agnes MacPhail
"Sleep is not something to be left for when you've run out of other, more interesting, things to do.  Sleep is a functional activity of the brain, during which stereotypical, well-defined processes occur.  These include the restoration and repair of brain tissue, the release of certain hormones, and the reinforcement of learning and memory.  Not getting enough sleep has the negative effects on these processes.  In the extreme, it can be fatal."

hese are the observations of Dennis Rosen, in The Optimist (November 2012).  He concludes...

"Most adults need eight
hours of sleep; teens need between eight and nine, and younger children need even more.  By taking this seriously... we stand to reap substantial benefits in our physical, mental, and emotional well-being
