THE MODEL OF SLEEP
In our sleep, phases of light sleep alternate with phases of deep sleep. A young person, falls asleep faster and the phases of light sleep are shorter. In an elderly person, the waking period is lengthened before falling asleep and subsequently wakefulness and very light sleep phases alternate more frequently. It can be said that with advanced age it is normal for the waking phases to lengthen and are not to be considered disturbing symptoms.
THE PHASES OF SLEEP:
PHASE 1: phase of falling asleep, twilight state between wakefulness and light sleep
PHASE 2: light sleep, the consciousness is dormant and the muscles relax
PHASE 3: deep sleep, sleep reaches its deepest stage. In this phase, organic regeneration also takes place, the heart rate and breathing are lowered, some organs reduce their function and some glands stop completely. This phase takes about 20-30 minutes.
Stages 1-2-3 are called SEM (Slow Eye Movement)
PHASE 4: REM sleep (Rapid Eye Movement) Under the closed eyelids, eye movements become very rapid. It is the phase of cleaning and reorganization of our mind, it is in this phase that we dream. Muscle activity is non-existent and it is very difficult to wake up the sleeping person.
The complete cycle lasts approx. 90 minutes and repeats several times during the night.
