Rapid Eye Movement (REM) sleep is a normal stage of sleep characterized by the rapid movement of the eyes.REM sleep in adult humans typically occupies 20-25% of total sleep, about 90-120 minutes of a night's sleep. During a normal night of sleep, humans usually experience about four or five periods of REM sleep.
Depends how long. If talking a few days than you get tired, memory negatively impacted, increased irritability... If talking a few weeks then psychosis and eventual death may occur from lack of sleep.
The most restorative stage of sleep is NREM-3.In a sleep cycle you progress through the stages:Initial sleep induction: NREM-1 -> NREM-2 -> NREM-3Full sleep cycle: NREM-3 -> NREM-2 -> NREM-1 -> REM -> NREM-1 -> NREM-2 -> NREM-3.A full sleep cycle takes approximately 90 minutes, but the time you spend in each stage changes during the night. At first you spend more time in stage 3, but as your body rests it will spend more and more time in REM.
Before your body goes to full sleep mode,your body shakes.(Sometimes you sleep through it)It gives you the illusion that you fell. Scientists are not exactly sure why,but that is where we get the expression falling asleep.
it blows up.
it happens in all cells in the body when they are deprived of oxygen.
you fell tired
When a person has been deprived of REM sleep for long enough they will not cycle through sleep patterns as a well rested person would. These REM deprived patients will enter REM sleep much more rapidly and will spend more time in REM sleep over the course of the night as their body attempts to "catch up" for the lost REM. This expedited process of entering REM is called REM rebound.
The body uses the time during sleep to regenerate and recuperate. In addition while asleep the brain dreams (both the kind you remember and the kind you don't) and works out it's problems and solutions to trauma and waking situations. When deprived of sleep the brain is also deprived of the ability to dream and work out it's problems. During tests that deprived people of sleep almost all exhibited marked tendencies to, in general terms, mental instability. While different people exhibit different specifics, all were markedly beyond the realm of normal behavior.
obviously weight loss Loss of hair Fatigue Stomach pain Dizziness Low blood pressure Swelling in the hands and/or feet Low body Temperature And ultimately death!
No sleep is healthy for the body
First, you will become extremely tired. You will become very lathargic, and after a long enough period without sleep, you will simply crash onto whatever it is you are on, and your body will force you to go to sleep. Basically, in time, if you don't sleep, your body will make you. you will faint
When you don't sleep for 2 nights in a row what happens is you will start to feel lethargic and could nod off to sleep anywhere. You may also be irritable and absentminded or not able to concentrate. It is not good to deprive the body of sleep so it is advisable to rest.
answer me back if im wrong but I asked my mom and she said it grows and grows and grows
