It is even the case that when you are over 50, on average you need less sleep than when you were younger. Every person is different and every age group is also different. There is no ideal length of sleep, and therefore no ideal amount of REM sleep. The magic number of 8 hours of sleep has been outdated for quite some time. How much REM sleep do you need per night? In addition, stress hormones decrease, so you can dream in a relaxed way. This is very important for the growth of our muscles and bones. About 70% of growth hormones are produced during this phase. In the process, we also produce less saliva and less urine. The pupils shrink, our heart rate slows down and we breathe less air. Brain activity goes up, but our body temperature that drops. What can be seen about our bodies in our REM sleep is quite a change from the other sleep phases. It would be what if you were chased in your dream, running out of bed. Researchers think that our bodies remain relaxed so that we don’t actually act out our dreams. During this, our bodies are completely relaxed, while our eyes move violently. During REM sleep, short-term memory is erased and we experience strong emotional feelings in our dreams. Little is yet known to scientists why we sleep, but it is now stated that REM sleep has an important function within the processing of events of the day and memories. We have this sleep cycle about four to five cores a night of about 90 minutes in length. The remaining stages of sleep are also known as NREM sleep, also known as Non Rapid Eye Movement. Because of this, this phase is also called dream sleep. In this phase we often have very lucid dreams, which we could later remember. Furthermore, the body is relaxed, but in your brain there is a very high brain activity going on. The most important phase of the sleep cycle is REM sleep, where REM stands for “Rapid Eye Movement.” Here the eye muscles move just as they do when we are awake, giving the brain fast and short electrical wave patterns. These are the slumber phase, light sleep, deeper sleep and REM sleep. While sleeping, our brain switches between these different sleep stages. In our sleep, we have a sleep cycle with different sleep phases. Need personal advice on how a mattress can improve your REM sleep? Below we will explain why sleep, and especially the REM sleep phase is so important. Researchers still do not understand why we need sleep, but suspect that it is required to recover ourselves physically and psychologically from a busy day. With this, sleep is an enormously busy activity for the brain. This is the phase where you sleep the deepest and where your body and mind are restored. Here the dream sleep, or REM sleep phase is the most important. Sleep is a relaxing activity for the sleeper.
