5 stages of sleep

Sleep in 5 stages.


The graphic representation of the registration of electronic waves emitted by the brains and the muscles show five stages of sleep: 4 are quiet sleep which becomes deeper and deeper and stage 5 is agitated sleep also called paradoxical sleep. During quiet sleep or non-rem sleep the electronic activity is equal to that of being awake during day time.

After falling asleep one passes progressively through the various stages of sleep:

Stage 1: Falling asleep, during this stage one can still understand what one is being told. The sleep is still very light. The waves slow down progressively, the brain produces high altitude beta waves, we become calmer and calmer, but we can still be awakened easily.

Stage 2: Slow superficial sleep, lasting approximately 20 minutes. We still hear from far away noise, but we do no longer understand their meaning. The brain experiences bursts of fast brainwaves.

Stage 3 and 4: the slow deep sleep. One is totally disconnected from the outer world with a heart ritme that slows down. Slow brain waves called, delta waves. Duration approximately 30 minutes. When we wake up in this stage we will be totally disoriented. It is in this stage that the brain secretes certain hormones as the growth hormone necessary for growth of infants and for the repairs of the organism in adults.

Stage 5: Paradoxical or REM sleep. So called by Dr.Jouvet because our brain is in complete activity in a completely immobile body with paralyzed muscles. This is the stage of rapid eye movements called REM (Rapid Eye Movements). Our breathing is irregular, so is our hart ritm. Sexual organs are stimulated.

It is important to realize that that sleep does not progress through these steps in sequence. Sleep begins in stage 1 and progresses in stage 2,3,4. After stage 4, stage 2 and 3 are repeated before entering REM sleep.

How to Stop Snoring and how to stop sleep apnea.

In stage 5, during paradoxical sleep, our muscle tonus goes down and the muscles of the nose and throat relax also. So do the muscles of our nostrils. The entrance of the nose gets blocked after falling asleep. A negative air pressure occurs in the airways of nose and throat. All tissue shrinks together and the air passage gets narrower. We start to lack air. Then comes the next step. To get more air, we turn on our back to breathe through our mouth. But in that position, on our back, the tongue and soft pallet fall back into the throat and block the airway in the back of the throat almost completely. The air accelerates and makes the soft tissue in the back of the throat vibrate, making the sound called “snoring”. In some cases the back of the throat is completely blocked, which we call a sleep apnea. It has to be emphasized that this complete complicated process starts with a closed nose entrance, resulting in a negative air pressure in the airways. To stop this process and to stop snoring and sleep apnea we need something that keeps the nose entrance open and allow more air to get through.

And that is exactly what the snore stopper “No Snoring More Air” does, and in a most effective way. It is the most simple and ingenious stop snoring device to stop snoring and sleep apnea. No wonder that this anti snore device is supported by most ENT specialists from sleep centers and sleep clinics.
