  Fact-checking   Autentic   DMCA   Report

The sueño cycle is a set of phases, which start from the moment when the person is due, progressing and becoming deeper and deeper until the body enters the REM sueño.

Normally, the REM period is the most difficult to achieve, but it is at this stage that the body is able to really relax and at the same time the brain renewal rate is greater. The mayor part of the personas follows the following pattern of phases of the sueño:

  1. Phase 1 Light Sueno;
  2. Phase 2 Light Sueno;
  3. Phase 3 deep swan;
  4. Phase 2 Light Sueno;
  5. Phase 1 Light Sueno;
  6. Sueno REM.

After being in the REM phase, the body normally returns to phase 1 and repeats all the phases until it returns to the REM phase again. This cycle is repeated throughout the night, but the REM time increases in each cycle.

Therefore, the process can be divided into 4 phases that are interspersed:

1. Lightweight Sueno (Phase 1)

This is a very light sweating phase that lasts approximately 10 minutes. Phase 1 of the person starts at the moment when the eyes are closed and the body starts to fall asleep, however, it is possible to wake up easily with any sound that is heard in the room, for example.

Some features of this phase include:

  • Not feeling that you are sleeping;
  • Breathing becomes slower;
  • It is possible to have the sensation that you are falling.

During this phase, the muscles are not relaxed, which is why, the person still moves in bed and can even open the eyes while trying to sleep.



2. Lightweight Sueno (Phase 2)

La phase 2 is the phase to which all the people refer when they say that they have a light sueño. It is a phase in which the body is relaxed and asleep, but the mind is attentive, reason why, the person nevertheless manages to wake up easily due to someone moving inside the room or to a noise in the house.

This phase lasts for around 20 minutes and, in many people, it is the phase in which the body passes more time after all the cycles of the sueño.

3. Deep Sweat (Phase 3)

This is the phase of deep sweating in which the muscles relax completely and the body becomes less sensitive to external stimuli, such as movement or noise. In this phase, the mind is disconnected, reason why there are no people. However, this phase is very important for body repair, as the body tries to recover from small injuries that appeared during the day.

4. Sueño REM (Phase 4)

The REM sweat is the last phase of the sweat cycle, which lasts around 10 minutes and normally takes 90 minutes to fall asleep. In this phase, the eyes move quickly, the heart rate increases and the eyes appear.

It is also in this phase that a disorder of sueño known as sleepwalking can arise, in which the person can get up and walk around the house without waking up. The REM phase becomes more extensive in each sueño cycle, reaching up to 20 or 30 minutes in duration.

How long does the sueño cycle last

The body goes through several cycles of the sweat during a night. The first one lasts around 90 minutes and then it increases to an average of 100 minutes per cycle.

An adult usually has between 4 to 5 cycles of sweating per night, which requires 8 hours of sweating.
