2. Adjust and maintain your work and rest: You can adjust your work and rest under special circumstances, such as slightly extending the class hours during evening self-study, but once you find that your work and rest rules have changed, you should adjust them in time and try to return to the original work and rest rules.

3. Exercise more and balance nutrition: Maintaining a healthy lifestyle is the key to developing a good biological clock, so it is necessary to strengthen physical exercise and do more troublesome exercises, such as running and swimming; And eat whole grains every day to maintain nutrition.

4. Avoid the reflected wave of the mobile phone: the bright screen and the weak reflected wave of blue light have something to do with staying up late, which will disrupt the rhythm of the biological clock. Therefore, it is recommended to put the mobile phone less than 50 cm away from the headrest before going to bed.
