When we sleep our eyes are closed and we are completely relaxed in bed. But not everything in your body is quiet. Did you know that there is still a lot of activity happening in the brain? This is especially the case during REM sleep , one of the sleep phases in the sleep cycle that we walk through. More about this activity, the sleep phases and the REM sleep you can read in this article!
The different phases of sleep
You go to bed, close your eyes and you wake up the next morning. Simply sat, you would think. But during your sleep, your body undergoes a lot of processes. You will not sleep ‘just’, but you will have different sleeping cycles.
These cycles (you have about five per night) consist of five different sleep stages. These phases always occur in a fixed order and so you go through a number of times a night.
Non-REM Sleeping Stage
Phases 1 through 4 belong to the non-REM sleep phase, ie the ‘non-Rapid Eye Movement phase’. These are the phases – the name already disappears – without ‘quick eye movements’. What this is and means means you read something further in this article.
Phase 1: The first phase belongs to light sleep and is the phase between waking and sleeping. This phase lasts approximately 3 to 5 minutes and is a phase where you reduce eye movements, close the eyes and still wake up regularly.
Phase 2: The second phase also belongs to light sleep, but lasts a lot longer. This phase is part of the “real sleep” and lasts about 45 minutes.
Phase 3: The third phase falls under deep sleep and lasts about 3 to 8 minutes. Your muscles are totally relaxed, your eye movements are slow and your heart rate decreases.
Phase 4: The fourth phase belongs to the very deep sleep and lasts about 15 minutes. At this stage, your body is totally relaxed. You’re hard to wake up. But if you get awake in this fourth phase, you can be quite disoriented.
Phase 5: The final phase of the sleep cycle is REM sleep, the phase of Rapid Eye Movement, ie: rapid eye movements. There is a lot of brain activity and your breathing and heart rate go up.
What happens during the REM sleep phase?
That REM sleep, what’s so special about it? Characteristic of REM sleep are the quick eye movements and dreams that you have. You are now also in your dream phase.
Features REM sleep
Great brain activity: no, your brains are definitely not quiet when you sleep. During sleep braking, this brain activity is even higher than during the day!
Relaxed body: Your body is completely relaxed in the REM phase and seems to be even paralyzed. Only your eye movements are very fast and your genitals are angry.
Dreams: The REM phase is the stage in which you dream. Your body is not completely relaxed. If you dream actively, that could affect your body movements. And of course you do not really want to run out of bed if you dream of being chased! Most people can make their dreams come true when they wake up in this phase.
Function of REM sleep
During the dream phase we are constantly processing information. The brains are very active and in your dreams treat the events of daytime.Experiences are being processed and memory refreshed.
That’s why it’s wise to sleep for a night before making an important decision!)
