Sleeping seems a trivial activity. Yet, behind, many events occur. During sleep, the body rests to restore energy that's been used. At that time, also, in the body happen a frenzy of activities that affect the physical and mental health.
In times of sleep, there's an increase in restoration of brain tissue and the formation of proteins, also anabolic hormones, such as somatotropin, corticosteroid, and gonadotropin.
People who sleep normally experience two cycles that come alternately: non-rapid eye movement sleep (NREM) and rapid eye movement sleep (REM).
NREM occurs when you experience light and deep sleeps while REM refers to the condition when you have a dream. Those whose sleeps dream arguably have a quality. The REM usually appears sixty to ninety minutes after sleeping soundly.
How important the sleep can be seen from the results of a study. Animals whose prevented sleeps would have a death after a few weeks although they were deprived of food, water, and a good and optimal living environment.
From the research, it's also revealed though not always, sleep disorders can endanger yourself and others. Mild sleep disorders can be said not to be dangerous because easily overcome without medication. If heavy, it's certainly dangerous and can be fatal if a sleep disorder causes an accident on the road or at work which also leads to heart failure and stroke.
For this kind of disorder, doctor's help and medicine becomes important.
