So why do we sleep?
this questions has been asked for centuries and the answers is... that no one is really sure.
We have to sleep because it's essential for maintaining normal levels of cognitive (to do with the brain) skills such as speech, memory, thinking and therefore sleep is significant in brain development.
sleep also allows our bodies to rest themselves and prepare for the next day (I'm sure we all know what hell it can being having an early start at work on only a few hours sleep!)
Sleeping also allows our immune system to regroup to be able to fight off all sorts of nastiness, research shows that people who do not get enough sleep are more susceptible illness and recover more slowly from an injury then those who get more sleep.
It also help us live longer!
Sleep is one of the single most important health steps you can next next to a good diet and exercise to keep your body strong (what more reason do you need to sleep!?)
But how much sleep is enough?
If you're thinking the 6 hours you managed last night was sufficient enough, think again. the National Institutes of Health reports that although the amount of sleep differs for each individual the average adult needs 7.5 to 9 hours to be well rested and awake.
So there you go sleep is essential for a long and healthy life! now I'm off to sleep in the college library to restore my immune system and to help my brain concentrate ;)
Thanks
