When you fall asleep, you enter a phase of light sleep (stage 1 then stage 2) followed quickly by deep slow sleep (stages 3 and 4). This phase is characterized at the brain level by very slow electric waves. It is accompanied by different physiological signs: the body cools, the movements of the eyes become scarce, the muscles relax completely. Heart and respiratory rhythms slow down.
After about 90 minutes paradoxical sleep appears. These different stages are the first sleep cycle in a night that has an average of 4 to 6 cycles, recalls the morphed network. In summary, the first half of the night is usually composed of a slow and deep slumber while the second half is made of alternating light sleep and REM sleep.
Deep sleep provides a breath of fresh air for the brain and the body thanks to sleep easy drops available in New Zealand. It is during this phase of deep slumber that the brain takes advantage of it to go about its nocturnal states. During deep sleep, the brain restores and stores energy for the next day. Memory is consolidated: the hippocampus and the cortex communicate to ensure the sorting and storage of memories.
