First of all, work and rest should be regular, and you can't stay up late. If the job is to stay up late, it is unhealthy to keep such a regular schedule and not to shift back to normal people's schedule during vacation.

Secondly, we should have a balanced diet, eat more fruits, drink more boiled water and touch less drinks.

Finally, exercise should be moderate and persistent, whether once a day or once a week. Look for the exercise that you can stick to, don't try strenuous exercise at once, and don't despise a simple exercise. Persistence is not simple.
