A complete sleep cycle takes 90 minutes. There are several such cycles throughout the night. At the same time, 90 minutes includes two phases of sleep: fast and slow. To feel rested, you need to wake up at the end of the cycle, not in the middle.
The best time to wake up is at the end of the deep sleep phase. On average, it occurs 90-100 minutes after falling asleep.
First, set a sleep schedule for yourself in 90-minute increments. This way you will sleep for 5, 6 or 7.5 hours, but you will feel much more alert than if you had 8 hours of sleep.
If you have little time to sleep or cannot sleep at night, then other methods will suit you. For example, polyphasic sleep. It involves several short periods of sleep during the day rather than one continuous sleep at night. The main difficulty here is for the body to adapt to the new regime.
Sleep quality is also affected by other factors that should not be forgotten. This means good ventilation of the room, a calm environment in the bedroom, tightly closed curtains.
