What’s one thing that everyone loves to do and talks about all the time… sleep. Everyone always talks about how they didn’t get enough or they had wonderful nights of sleep, either way everyone once a day at least says something that refers to sleep. Sleep is a very important part of life. The proper amount of sleep and going through the sleep cycle four or five times a night is what’s even more important. If you don’t get the proper amount of sleep or go through the sleep cycle the right amount then your body isn’t going to be as healthy as it should be. Sleep is more important than people really thinks it is. Sleep helps your body recover when you are sick it, it also keeps your body health and it makes your immune system strong getting the

It really depends on how tired you are and how well you have been sleeping to depend on how you go through the sleep stages. The being of the sleep stages lasts about 90 minutes and each of the successful cycle’s averages to be 100-120 minutes long, but it differs within each person and with children it is usually shorter. The beginning of the cycle begins with the non-REM which has three stages in it. Which they are call; stage one (NREM 1), stage two (NREM 2), and stage three (NREM 3). Each of these stages can last five to fifteen minutes (WebMD). In stage one (NREM 1) “the first short period of very light, easily disrupted non-REM sleep, between wakefulness and sleep proper, characterized by alpha waves and theta waves and often punctuated by sudden twitches or hypnic jerks (sometimes called somnolence or drowsy sleep)” (Mastin). Next is stage two (NREM 2) “the second stage of non-REM sleep, and the stage in which most time is spent, characterized by higher voltage sleep spindles and K-complexes” (Mastin). Also, in stage two your heart rate slows, your body temperature drops and your body is preparing to go in to the third stage of sleep (WebMD). Stages three (NREM 3) which is the last stage in non- REM “the third and deepest stages of non-REM sleep, during which the …show more content…
It is characterized by quick, random movements of the eyes and paralysis of the muscles” (Medical News Today, What is rapid eye movement? What is REM?). People usually experience REM sleep four or five times a night which occurs in a cycle. The first time REM occurs is at the beginning which lasts only for a short amount of time but, after each cycle each time you go into REM it lasts longer each time. It is common for people to experience light sleeping or even waking up after each cycle. After each cycle people can wake up for a very brief moment that they don’t remember or even realize they woke up at night. When you are in REM sleep most of your muscles go paralyzed and the activity of the brain’s neurons becomes quite intense, similar to the activity during wakefulness (Medical news today). Some sleep researches have said that the brain activity is some times higher in REM sleep then it is in wakefulness. During REM, certain neurons in the brain stem, REM sleep-on cells, becomes very active. These cells are most likely what triggers this phase in the sleep cycle. After triggered when you are in the state of REM, the body stops releasing neurotransmitters called monoamines which are responsible for stimulating the motor neurons, causing the state of temporary paralysis (Medical News Today). Some people’s muscles don’t become paralyzed and their muscles
