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.
Because of this, insufficient sleep can be unhealthy and even dangerous. One of the first systems affected by lack of sleep is the immune system. Too little sleep damages immune function and makes us vulnerable to illnesses. Hence, adequate sleep is required for truly healthy immune function. Another organ negatively impacted by too little sleep is the liver. The liver is the largest of the internal organs and has over 500 functions in the body. One is regulating the energy level one will have for the next day so that staying up late and not sleeping long enough impairs the liver’s ability to do this and other jobs.
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.
Some people are able to function well with less, but most people should try for a full eight hours. Adequate sleeping time is essential to get all the repairs made from the day and to filter all the toxins. When we do not get enough sleep for repair, we feel tired and require even more sleep to “catch up” for that time we missed. The body may literally cry out with various discomforts for enough sleep.
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.
