When technology to monitor our body was developed, it was only then that scientists were able to make comprehensive studies on the effects of sleep to our body. They found out that for an average adult the body needs about 7 to 9 hours of sleep every night. Less than that would elevate the risk of contracting diseases and aggravating present illnesses. Good sleeping practices also promote good health benefits in our body.
The most prominent benefit we can get from sleep is helping our body to regenerate. When we are resting, our body can concentrate on fixing the damage to our cells that is caused by stress and toxins in the environment. When we sleep, the body produces more protein that is used to rebuild damaged cells.
An obvious benefit of sleep is the relieving of mental and physical stress we acquire throughout the day. When we go into REM sleep or rapid-eye movement sleep, which is the deepest level of sleep, our mind is believed to be organizing our memory of the past day. It also is believed that our mind is repaired at this level of sleep.
During sleep, our body normalizes our hormone levels. It also helps our muscles and organs to relax and reduce damage from wear and tear. This decreases the rate of degeneration of our body and thus reducing the effects of aging.
During sleep our heart beats at a steady pace. This regulates the blood pressure in our body and helps relive the build up of cholesterol that may cause heart attacks. It also helps the blood in the efficient delivery of the sustenance our body needs.
