How to keep energetic and avoid sub-health state?

Exercise more and do less harmful things, such as staying up late for a long time and being too emotional, such as continuous high-intensity work without rest, which will damage your health. You need to focus on the most critical place. In addition to normal work, we should have appropriate entertainment, but these entertainment should not affect our health. Doing more exercise can greatly improve a person's physical fitness and give you enough energy to do what you want to do.
