You can study and work normally, but the efficiency is very low. This is a sub-health state of your body. There is no good way to regulate specifically, because sub-health is not a disease to some extent. It is the decline of our physical quality and the decline of our metabolic rate. Only through some similar means of health preservation.
If you find that your body is becoming sub-healthy, you should adjust the pace of life in time, get enough sleep every night, and then try to spare half an hour for running during the day. The head can exercise our whole body function, accelerate our metabolism, improve our vital capacity and enhance our immunity.
It is necessary to distinguish between public and private, work is work, and private life is private life. Don't confuse it. After work, we should try our best to transition our life into a health-preserving mode, such as normal running, reading and sleeping, so as to maintain psychological and emotional stability. Don't think about how the work should go smoothly after work. Our body is not a machine, it needs a proper rest. Our brain, our organs, need appropriate time to restore its vitality, so don't be tired for a long time, which will cause irreversible harm to the body.
