Everyone must have enough sleep, which is a great guarantee for health. If you work at night, why not set aside more time for yourself to sleep during the day? As a person who works at night shift, your pace of life is only half a day away from that of normal people. You should push your normal life forward or backward for half a day, so that you won't feel sleepy at work and don't need anything to refresh yourself. Besides, you can't drink too much coffee, which is very bad for your health. Tea is good for your health, but you can't drink too much.
