Optimize for REM sleep
Rapid eye movement sleep is very important. This stage of sleep should be optimized. You need to pay attention to the time when it occurs. This phase repeats itself every 90 minutes of our sleep. You can control the quality of sleep and wake up fresh and well-rested if you work this backwards and set your alarm according to this time. For example, if a person wakes up at 6 a.m., he or she will need to go to bed before after 10 p.m. or right before midnight. A sleep calculator can be used to help you count the time more precisely.
