This question is hard to say. I think it may affect my physical and mental health a little. Many health experts will not say that going to bed early and getting up early is the healthiest way of life. If there is nightlife, first of all, work and rest must be reversed, which will affect rest, and people who rest may get sick. Secondly, it will definitely affect the harmony of the family. If you go out to play, you should come home late, and then you may drink some wine and play cards, and your family will be angry. Finally, you may eat too much unhealthy food or drink too much wine, and your body will have problems.

First of all, talk about the impact on rest. I believe everyone can often hear the old people at home say that going to bed early and getting up early is the healthiest way of life, and how many hours of sleep should be guaranteed. If you go out to play with friends or colleagues, you will often stay up late, maybe in the early morning, and you may have to get up for work the next day. Staying up late for a long time is bound to be a little uncomfortable, listless and often tired.

Secondly, it affects family harmony. Nightlife includes foot washing, smoking, drinking and nightclubs. If you have a family, you won't go home too early, and you will definitely have conflicts with your family. That will affect family harmony.

Finally, there are health problems. Many people say that the food outside is not as hygienic as at home, so I guess. Eating too much greasy food will also cause some minor problems in the body, and drinking too much wine will also hurt the body. As time goes on, unhealthy lifestyles will show up in your body. Therefore, nightlife will still affect physical and mental health, or we should grasp that degree.
