Sleep Can Give You A Strong Immune System

May 1, 2008
At one time sleep was considered just the time you were not awake as a single entity, but now we know that sleep has several different stages where different processes occur. During sleep there is quite a bit of brain activity and many functions are performed that are essential to our health and well-being.

On the other hand, not getting enough sleep can be dangerous. The first thing it affects is our immune system. If our immune system is not strong enough we will fall sick. It seems one of the main organs that is involved in a good night's sleep is the liver. It regulates our energy level for the next day. When we stay up late at night we affect the liver's metabolism.

It is said that a person requires at least eight hours of sound sleep. After a days work the body needs to rest in order to restore the damages occurred during the day. The liver itself does over 500 different specific functions one of the most important being cleaning the blood. There is lot of chemicals now in air, water and food; because of this the liver is being overburdened to clean up everything which is another function of the liver. Thus we see that liver does many different functions during the day and so there is the need for the body to shut down and sleep to repair itself. Some people sleep less than eight hours. However research done on sleep has shown that the brain needs to have at least three hours to shut down, for it to kind of reset the cycle.

Research indicates that the brain requires a minimum of three hours. However, if a person continually only gets three hours a night, his/her body will not have a chance to repair itself, and illness or exhaustion will likely occur.

The brain may function with merely three or four hours of sleep, but it will not function at its best without that eight hours we truly need. Liver function also impacts the immune system so sleep is doubly important. We must have a strong and vigorous immune system to fight invaders like viruses, bacteria, fungi and parasites, so enough sleep is essential for everyone. Getting adequate sleep makes for a healthy liver and a strong and vital immune system which makes us feel better and be healthier.
