How many hours should adults sleep?

Adults sleep 7-8 hours. During their sleep every night, they complete their sleep cycle every 2 hours or so. If they sleep for eight hours, they should cycle four sleep cycles. Each sleep cycle begins with hazy sleep, then gradually deepens into deep sleep, and then turns into non-rapid eye movement dreaming sleep.

The time to get good sleep quality is from 9: 00 pm to 1 1 pm, which makes people lack energy, slow response and slow thinking, and is beneficial to people's transition to slow-wave sleep.

The best sleep time is from 1 1 to 6: 00 the next day, while the prime sleep time is from 1 1 to 3: 00 the next day. At this time, the metabolism of the liver is the most vigorous. If you miss this golden time of sleep for a long time, you will have sleep disorders, leading to physical dysfunction.

The method is simple. After lying in bed, relax, take a few deep breaths first, then start counting your income, or you can count your commitments, from the first to the tenth, and then start from the first;

I often can't count to ten, or I can't count to ten. This is because my mind is already thinking about the stock market or other similar things. This is a normal phenomenon. At this time, I have to count again. This cycle, unconsciously, has fallen asleep.
