Let's face it, a lot of people in the United States are charged with failing to get enough sleep. According to numerous health and fitness studies, the 8 hours that's normally recommended for Americans has been reduced to an average of 6 1/2 hours of sleep per night.

Therefore, the population as a whole is currently at risk of experiencing a wide diversity of unwanted health problems and other related issues. So, for those of you who fit into this category, here's some essential facts that you should know. All of which are centered on the questions, why we need sleep and what actually happens when people do not get enough?

Immune System Breaks Down

One of the first things that people should know is the lack of rest is responsible for many different health problems including the immune system of an individual breaking down. These problems may start off small but may quickly escalate to sever concerns if the person goes without proper amount of rest for extended periods of time. For instance, if an individual is already tired and run down, it makes it very difficult to fight off various kinds of communicable diseases and illnesses.

In fact, one illness that many people may have problems fighting off is the common cold. Since the body's system has to be built up to fight off bacteria that spreads from others, rest is a necessity and not a luxury. Also, if the person catches a cold, it can easily graduate into bigger problems like flu or pneumonia if the person is not getting enough fluids in their body or the proper amount of rest.

Regeneration Needed for the Rebuilding of Healthy Cells

If an individual cuts their finger, they may not need to put any type of medicine on it for it to heal. In fact, if the person is healthy and well rested, the body will begin to repair itself. In many cases, this restoration usually occurs during the night while the person is resting. Therefore, if the person does not get enough rest, they may find that the body does not repair itself at all and a larger sore may begin to form. Basically, the process described above involves the regeneration of the body's cells.

It's Healthy for the Brain

It's not uncommon for an individual to be so tired that they can not think. This is because the amount of rest that a person gets per night does have a direct impact on how the brain functions during the day. In cases where the person does not get enough down time for long periods, they may have problems recalling the simple facts they have already learned. However, when the person has had enough rest, studies have shown that people do much better on passing tests in school and functioning better on their jobs.

Getting enough sleep at night is not a luxury but a necessity. Since it impacts so many different things directly and indirectly, people can not go without it for long periods of time. When a person does not get enough rest, they are at risk of numerous health problems and concerns including the breakdown of the immune system, loss of essential cell regeneration and problems with thinking and functioning properly at school and on the job
