Human sleep is related to melatonin secretion and core body temperature. Generally speaking, at 7 o'clock in the evening, the body temperature reaches the highest, and then it begins to drop. Melatonin was secreted at 9 o'clock, and 10 intestinal peristalsis was inhibited. In other words, the time from melatonin secretion to intestinal peristalsis inhibition is the time to start sleeping. 2 am to 4 am is the deepest time to sleep, and this time is also the easiest time to doze off.
Moreover, as far as research is concerned, drugs such as exogenous melatonin have little effect, and more are just psychological hints. Therefore, patients with sleep disorders should seek medical treatment in time and take measures.
Extended data:
The total sleep time every day and night in a person's life decreases with the increase of age, especially in the early life, and it is stable at about 7-8 hours every night in adolescence. Most elderly people sleep less at night, averaging about 6.5 hours, and deep sleep is also reduced, so their energy and physical strength during the day will be worse than when they were young.
If middle-aged people lack sleep, it is mostly related to mental decline or stress. In addition to relieving stress as much as possible, you can also work hard in the sleeping environment, such as reducing noise, ventilation and proper shading. And choose a shorter and softer pillow. The length of sleep depends on personal needs. If people who sleep for too short a time feel lack of energy, they should make appropriate adjustments.
However, too long sleep time is not the best, and appropriate adjustments are needed. Pay attention to the length and quality of sleep, which requires us to form the good habit of going to bed early and getting up early and live a healthy life. People who still don't get enough sleep can also make up their sleep by taking a lunch break 1 hour.
