Deep sleep is one of the stages of slow-wave sleep. Sleep is a heterogeneous state.
Deep sleep is divided into slow and fast phases, which alternate several times a night.
During REM sleep, a person's eyeballs move, breathing and heart rate increase.
Each person is individual. For some, literally 90 minutes spent in deep sleep is enough, while others need about 300 minutes.
All of the stages of sleep are important, but deep sleep is responsible for having you feeling restored when you wake up
Research shows that you can achieve the required time of deep sleep by following the following rules: Go to bed at the same time (no later than 23:00);
Do not exercise 1.5–2 hours before bedtime;
Do not drink coffee or alcohol before bed, do not smoke, try not to eat anything (especially spicy foods).
Create a bedtime ritual: systematically take a bath, brush your teeth, and wash your face at the same time.
Eat foods with tryptophan, which helps in the production of melatonin: cheese, fish, cottage cheese, legumes, dates, sesame seeds.
Do a relaxing neck massage. Especially useful for people who spend a lot of time on a PC.
