On the Value of Sleep

Every time I have thought I was putting enough value on sleep I was wrong, but what I have learned from this is that it's nearly impossible to put too much value on getting enough sleep.  Funny how our society considers this thing that's completely essential to our ability to function as a 'luxury'.

Things I have learned about sleep:
*sleep deprivation reduces ability to behave compassionately towards others (not that our society cares about that!)
*sleep may be used to remove waste from the brain
*sleep deprivation causes significant cognitive impairment  (for those who need to use your brain to do things for school or work or to operate heavy machinery)
*sleep deprivation greatly exacerbates depression and anxiety

Conclusion:
Sleep is important.  It is not a luxury.
