Letting Sleeping Dogs Lie

Everyone needs to sleep. This is a fact that can not be contested. Sleep slows the body down, putting every major component from the body into a more relaxed state. It is also recognized as a medical fact. People dream while they were sleeping and, in theory, animals can also experience dream-like scenario. Apart from the fact that most people do not remember them, this can also be medically ascertained. However, apart from all the effects listed above (and side effects), what exactly do for a person to sleep? A little less clearly known, which may be the reason why so many institutions and research programs to study deep into the scientific facts behind sleep.

Natural growth hormone that the body needs to develop is produced in large numbers during sleep. This is often seen as an explanation of why the people who do not sleep too often eventually become a little shorter than their friends. These hormones are produced at their peak during puberty and tends to stop the production after that. People are still not sure why the body produces more during sleep. There are some who theorize that this is just part of the side effects of sleep, sort, on the grounds that the body is too busy coordinating themselves to actually produce growth hormone. However, this assumption is somewhat debatable because the body is still the same coordinate system during sleep hours as during waking.

According to recent studies, sleep may have the effect of age and welfare. People who experience sleep attacks finally experiencing extreme degenerative state of physical health, with prolonged sleep deprivation becomes deadly. It is still not sure exactly why this happens, despite the fact that this could happen is not being debated. Research shows that people who have lost sleep for long periods of time physically withered. According to some findings, the mind is also highly affected, with anxiety and depression into the potential effects of over-extended awake. This is often associated with disruption of normal production and flow of the central nervous system biochemical agents, which set the mood and emotional stability, among others.

The nervous system also suffered from lack of sleep, according to several new findings. People who do not sleep on a regular basis tend to have unstable moods and poor reflexes. In most cases, vigilance and awareness tend to compromise the environment, often to the point that even simple tasks can require more concentration than usual to perform well. Part of the brain that controls motor functions and reflexes are not the only part that suffers, as a region believed to regulate actions for the social situation is also known as compromised. Currently, there is no certainty to only what happens during sleep that causes this, but there are several theories.

There are several theories related to sleep being tested, what kind of dreams serve a biological purpose, but they are considered less of a concern. Some findings even indicate the possibility that the human body's natural state (and, indeed, any animal's body) will sleep, rather than awake. This is somewhat surprising that sleep, something that is integral and essential to maintain human health, very little understood by medical science.
