In the first stages of sleeping, the body begins to relax, the heart rate slows, and people often feel as though they are falling or otherwise weightless. As the body slips into the second and third stages of the cycle, it is very apparent that the brain is not acting in the same way (i.e. emitting the same brain waves) as when the body is awake, but nevertheless the activity is still there. This is where your body performs daily maintenance and healing, and where deep restful sleep occurs.

Scientists are beginning to realize that sleep is not just a mental recharger, but also important for the body as well. When a person sleeps, the body and mind are working just as hard as when the person is awake, correcting chemical imbalances, assuring proper blood sugar levels for the next day, and maintaining the memory.
It is not quite clear what physically happens in the body when one sleeps. Although scientists can read brainwaves on an EEG, they are not sure when exactly the brain is doing, although they acknowledge that dreaming is a large part of it. When the body is sleeping, the brain goes through four different stages, called the REM (Rapid Eye Movement) sleep cycles. At different stages, the brain is active in different ways, as seen on EEG brainwave readers.

The brain stem controls vital processes like breathing and circulation but it also controls sleep and arousal (as in waking up). Also, the pons is an area in the brain that controls sleep and arousal. It releases serotonin and melatonin which are the bodies natural chemicals that make you drousy (it can also be purchased for those who have sleeping problems) and then another part of it signals you to wake up (unless you are woken up by outside forces like loud noises). The Circadian (spelling?) rhythm also plays a part in sleep patterns. For most people your biorhythm is set to wake you up when it gets light and to make you sleepy when it gets dark. However, there are many people who train themselves to do otherwise, like if they have to work the graveyard shift, but then they get their own sort of rhythm. When you change your rhythm abruptly it can be hard to stay awake or get to sleep, like when you get jet lag. There are many things that control sleep, it's mostly a balance.

Throw on some earphones and daydream..... Relax.
That's how I fall asleep or I watch an old black and white movie until I go out.
