Sleep Intro 2

What Does Sleep Do For Us?

You can spend thousands of hours by reading books on sleep, scientific magazines, or just surfing the Internet on this subject. The final result will be the same:  every sleep researchers are still at the beginning of this exploration trying to understand exactly why people require sleep. All they could come up with that when study has been performed on animals, it shows that animals need sleep for their basic survival. Here is the result of that research: 

Lab rats, being deprived from REM sleep, live only five weeks on average. However, they normally live for two to three years. Lab rats being deprived of all sleep stages manage to stay alive for 3 weeks. The rats’ immune systems also become impaired due to the act that rats’ body temperatures significantly decreases, as well as they develop considerable pain in their tails and paws.

All researches agreed that sleep deprivation affects the immune system in humans in detrimental way as listed below:  

We need sleep for our nervous systems function properly.

Reduced sleep makes us drowsy and we have difficulty or completely unable to concentrate. 

Reduced amount of sleep leads to impaired memory

Reduced sleep results on our physical performance

Sleep deprivation leads to inability to carry out calculations, engineering tasks, and art

Prolonged sleep deprivation may result in hallucinations and mood swings. 

Latest development in sleep disorders conducted in different countries demonstrate common results: 

While asleep curtain number of our neurons are shut down performing self-repair.

With sleep deprivation our neurons become depleted in electrical charge energy and even polluted with by-products of normal cellular activities that they begin to malfunction

Our brain, being deprived from sleep, may also disconnect critical neuronal connections, which becomes deteriorate from lack of activity

Release of growth hormone in children and young adults directly related to the amount of deep sleep

Increase in production and less breakdown of proteins during deep sleep of the body’s cells also show

During deep sleep curtain parts of the brain that control decision-making processes, our decision-making processes emotions, and our social interactions are dramatically reduced in their activity. It suggests that deep sleep may help people to maintain optimal emotional and social functioning while they are awake.awake  

Deep sleep should be called “beauty sleep” based on the fact that proteins, neurons’ building blocks, are directly involved in cell growing process. Those building blocks are needed during cells repair after stress and ultraviolet rays from the sun.
