Sleep: The Benefits, The Facts, The Disorders, And Much More
Sleep is an reiterated anabolic state that living things enter that is defined by the amount of consciousness we receive, sensory, and the relaxation of muscles. It is necessary because it helps to rebuild or rejuvenate the immune, nervous, skeletal and muscular system. Hence, all mammals, birds, and some reptiles, amphibian, and fish must sleep.
The research that has been done to study sleep has only resulted in finding out about some purposes and functionalities of sleep. Sleep is thought to have a part in decreasing your metabolism by 5 to 10 percent. Even hibernating animals such as bears need sleep despite hypometabolism and must return from different levels of homeostasis in order to sleep.
After some research was done about sleep, one conclusion was that we need sleep because we get sleepy. Through evolution, it is thought that sleep changed due to fulfill some primeval function in our bodies. Also, sleep is thought to have taken on some more responsibilities and functions that deals with the passage of air and food. Therefore, it is beneficial for the average adult to receive around 7-8 hours of sleep on a daily basis.
Stages of Sleep
This stage is where you are lightly sleep and you are able to be woken with a gentle shake, touch, or by noise. You start to lose muscle tone, where your muscles start to relax, causing twitches and jerks. You begin to have hypnotic hallucinations such as seeing lights and colorful patterns that causes your mind to be put into a restful sleep. Also, in this stage, you lose self awareness and attachment of your senses to the physical world
This is the stage, where you begin to lose all of your muscle tone so your physical body can't act our your dreams. Your brainwaves continue to show bursts of high activity even though they have slowed. These bursts of high brainwave activity are called sleep spindles. All in all, we spend about 50 percent of our sleep in Stage 2; a light dreamless sleep.
This is the stage, where you began to experience deep sleep also called Slow Wave Sleep. If you are awaken at this stage, you will feel dopey and confused for a couple of minutes, even though it is hard to awaken someone in this stage of sleep. You are also prone to experience dreamless activity in this stage and sleepwalking could occur.
This is the stage, where you experience the deepest part of a deep sleep or Slow Wave Sleep. This stage replenishes your energy physically and mentally. Without enough deep sleep, you won't feel refreshed and energized the next morning.
This stage is called the REM stage or Rapid Eye Movement stage. This stage is the where you start to dream. If you are woken up in this stage of your sleep cycle, then the next night when you sleep you will return to this stage right away. Also, this stage creates long term memory and lucid dreaming.

There are quite a few benefits of sleep. Some of these benefits you may be aware of and there are some that you didn't know existed. The benefits are as followed:

Myths and Facts
Myth: Anyone can drink alcohol or wine with sleep medication so that it can help you to fall asleep faster.
Fact: Sleep medication should not be taken with alcohol, before you drive, take a bath or before operating machinery. Also, follow your doctor's instructions about when to take, how much to take, and how long you should take your medication. Alcohol may calm you and may help you to fall asleep, but it also increases the amount of times that you awaken through the night
Myth: Sleep aids are not safe and that you can become addicted to them
Fact: Sleep aids are safe, when they are prescribed by a professional and you take them according to the instructions that you have received by the doctor or the recommended amount on the box. The newer sleep aids don't have the same effect as benzodiazepines, which means there is a lower risk for dependency on them. On the other hand, people that have a history of alcohol and drug abuse have an increased risk of becoming addicted to sleep medication.
Myth: Exercising before you go to sleep will make you tired and help you to sleep.
Fact: Exercise can be helpful in receiving good sleep, if done on a regular basis in the morning or the afternoon and not too close to bedtime. Research has been done that you shouldn't exercise up to three hours before you go to sleep because it causes you to be alert and raises your body temperature. This results in you being able to fall asleep easier hours later.
Myth: Watching television and using your laptop will help you fall asleep.
Fact: When you are working, watching television, using the computer close to the time that you fall asleep will cause you to receive less quality sleep. Violent shows, stories, and the news can cause you to be more alert and agitated. Therefore, the sleep environment should be used for sleep and sex.
Sleep paralysis is when you experience the temporary inability to move, either when you are falling asleep or when you are wakening. This phenomenon has happened to many people, even though some people did not know what it was called. This was found to happen mainly in the REM stage of sleep or the fifth stage of sleep, where we experience deep memory of Slow Wave Sleep. This stage is also defined by muscle weakness which prevents people from acting out their dreams. This phenomenon is also known to be linked to another disorder called narcolepsy
This is the condition where someone doesn't receive enough sleep, which could be either long term or short term. The cons of not receiving enough sleep is that you can experience extreme tiredness, daytime sleepiness, clumsiness, and weight loss/gain. The absence of sleep in humans is impossible unless they suffer from fatal familial insomnia. Brief naps or microsleeps can't be avoided. There have been studies that have shown that long term sleep deprivation has caused death in lab animals
