Everyone has a physiological clock in his body, which shoulders different physiological tasks at different times. Don't ignore it easily! Biological clock indicates: 1.00: 00-0 1: 00 light sleep period-dreamy and sensitive, people who are unwell are likely to wake up in pain 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.
