Sleep stages

Once a person falls asleep, his body passes 3 stages of “Non-Rapid Eye Movement”, followed by one stage of “Rapid Eye Movement”.

A person spends more time in the first half of the night in the sleep of non -rapid eye movement, and with the passage of night he spends longer when sleeping fast eye movement.

The first stage of sleep represents the short stage in which a person moves from vigilance to sleep, when breathing and heartbeat begins to slow down.

Breathing and heart rate slowly slow down, the second stage, the body temperature decreases, and the muscles relax. The second stage sleep continues for a longer period in each cycle throughout the night, and a person spends about half of his total sleep every night at this stage.

The third stage represents the deepest sleep in the sleep cycle, in which the brain waves are in its slower frequency and the highest capacity.

During deep sleep, the functions of the body, such as breathing and heart rate, are very slow, and the muscles are relaxed, and it may be difficult to wake up at this stage, and he may make him feel waking up from deep sleep with mental blurry for up to an hour.

After all this, a person moves to the sleep of rapid eye movement, and as the name suggests, the eyes move quickly under the eyelids during this period, and the activity of the brain is similar to the activity of the awake person without moving the muscles, and experts believe that most dreams occur during the sleep of rapid eye movement.

It usually takes between 90 and 120 minutes to move between the four stages, after which the cycle begins again. Adults usually pass 4 to 6 sessions per night.

Research conducted by the Monash College of Psychological Sciences and the Turner Institute for brain and mental health in Melbourne, Australia, showed that the lack of deep sleep may increase the risk of injury Decoration.

How long do you need?

The amount of sleep that a person needs in general must be determined to calculate the amount of deep sleep, and most adults should aim to get at least 7 hours of sleep every night, and up to 20% of this time spends deep sleep.

Deep sleep begins within an hour of sleep, and deep sleep periods become shortly shorter with the passage of night. The body regulates deep sleep, as a person who recovers from a period of deprivation spends a longer time in deep sleep, in contrast to that, people who sleep repeatedly from a deep sleep may happen, as part of their deep sleep needs may happen already during the day.

The elderly gets less than deep sleep, and they compensate for more sleep in the second stage.
