The biological clock says:

1.00: 00-0 1: 00 shallow sleep period-dreamy and sensitive, people who are unwell are likely to wake up at this time.

2.0 1: 00-02: 00 Detoxification period-At this time, the liver is actively eliminating toxins, so it is necessary to put the body to sleep before the liver can complete the function of metabolizing waste.

3.03: 00-04: 00 Hibernation period-the most vulnerable moment for critically ill patients, and patients often die at this time. It is best not to stay up late beyond this time.

4.09: 00- 1 1: 00 essence period-this is the best time for attention and memory, and also the best time for work and study.

5. 12: 00- 13: 00 lunch break-it is best to sit still or close your eyes before eating. Don't drink at noon, it's easy to get drunk and hurt your liver!

6. The peak period 14:00- 15:00- is the time when analytical power and creativity can be brought into full play!

7. 16: 00- 17: 00 low tide-the stage of weak physical consumption, it is best to supplement fruits to relieve hunger and avoid overeating leading to obesity.

8. 17: 00- 18: 00 relaxation period-at this time, blood sugar rises slightly, and the sense of smell and taste is the most sensitive. Dinner should be prepared to boost your spirits.

9. 19:00-20:00- It is best to take a walk or take a bath 30 minutes after meals to relax and relieve the fatigue of the day.

10.20: 00-22: 00-this is the peak time of evening activities, so I suggest you make good use of this time to discuss, study and other activities that need careful consideration.

1 1.23: 00-24: 00 Night sleep period-after a busy day in the city, you should relax and fall asleep at this time. Don't overload your body, it's not worth the loss!

Sleeping is asked by the university! As the saying goes, going to bed early and getting up early is good for your health. There is only one concept, no quantification and no meaning. The key to sleep quality lies in deep sleep. It can be said that only 2~3 hours of sleep is enough. Usually 0 to 3 o'clock is the time for deep sleep, but you can't go into deep sleep as soon as you fall asleep. There is a transition period, usually 1~ 1.5 hours! Conversely, it is best to go to bed from 22: 30 to 23: 00.

Prepare for deep sleep!

When do you get up? Internationally recognized is 6 o'clock.

Coupled with the changes in natural seasons,

The recommended timetable is:

Summer 22: 00 ~ 23: 00-> fall asleep at 6: 00 to 7: 00-> get up.

Winter 21:30 ~ 22: 30->; Fall asleep at half past six to half past seven-> get up

At noon, the alertness of the human body is declining. At this time, taking a nap helps to restore the spirit and is conducive to work, study and physical health.

In addition, dinner should be finished two hours before going to bed.

Because growth hormone reaches the peak of secretion at night, eating supper will affect the secretion of growth hormone, thus affecting the growth of the body. If you are really hungry, you can eat something high in protein, such as eggs, bean products and milk.

The best sleep time for all ages is as follows:

20 hours for newborns

Baby 14- 15 hours

Preschool children 12 hours

Student 10 hour

Middle school students 9 hours

8 hours for college students

Adult 8 hours

6-7 hours is too long and too short for the elderly, 7-8 hours is suitable!

A study conducted by scientists shows that if people spend too much time in bed every night, its impact is just like sleeping too little, which will lead to many sleep problems. For example, people who sleep more than 8 hours and less than 7 hours a night complain that they have sleep problems. People who sleep seven to eight hours a night have fewer sleep problems. I also believe that many people have this experience: once they sleep late, they feel groggy and don't want to get up. The more you sleep, the more groggy you are. You spent your last day in a daze and couldn't sleep at night! If you want to have a good sleep, you must control your time!

At the same time, we should adjust the length according to the season, sleep less when the summer nights are short, and sleep more when the winter nights are long and cold! Sleep 7~8 hours in summer and 8~9 hours in winter! On this basis, children will increase 1~3 hours, and the elderly will decrease 1~3 hours.
