Why do we have to sleep?

{ Posted on Jan 03 2008 by arthur }

As the day progresses you become more and more sleepy, until after dinner when you can’t take it any longer, and trudge off to bed.  We all know that healthy sleep patterns can promote immune system functions, alertness, and general health.  But what makes us fall asleep in the first place?  Scientists have pinpointed Adenosine.  It is a by-product of the brain that is left over from ATP, a phosphate used to fuel brain reactions.  After the phosphates are used up, all that is left is the Adenosine.  It then attaches itself to arousal receptors in the brain, blocking the receptors, and then causing you to become sleepy.  After a few hours of sleep, the muscles restore energy, your brain restores energy, and the Adenosine levels return to normal.  If you would like to read the whole article used for research, click here.

If you aren’t getting enough sleep during a typical night, your body goes into a sleep debt.  Yes, more debt to worry about.  Let’s say you only get 5 hours of sleep one night, for whatever reason, the next night your body will try to regain the important stages of sleep that you were cut short from.  If the next night you still do not get enough sleep, you will further your sleep debt.  The body will always try to make up deep sleep (stages 3 and 4) first before making up REM sleep.  But it is important to make up your sleep debt.  If you would like to read more about sleep patterns, needs, and difficulties;  click here.
