Sleeping is a regular habit and, in fact, a biological necessity. It is one of those things that people need to do in order to give the body and brain enough time to rest and rejuvenate. The typical sleeping positions would be to lie down with closed, preferably on a comfortable bed. A person who wants to get some sleep usually tries to minimize distractions and any loud noise that might prevent one having the right atmosphere for sleeping. During sleep, a person usually breathes in a slow and rhythmic pattern, with muscles completely relaxed. A few minutes or some hours after falling asleep, one would occasionally roll over or change body positions. This change in sleeping posture occurs around once or twice every hour. This can be the body’s way of making sure that no part of the body or skin has its circulation cut off too long a period of time. Basically, a sleeping person is unconscious of the things that are happening around in the environment. But for some people, they may be getting lack of sleep due to several factors. Stress, fatigue, and worry may be some of the reasons why people do not get enough sleep.
