Students' understanding of health often focuses on mental health and ignores the consideration of physical health. The monitoring results show that the development level of college students' height and weight in China is on the rise. Various health indicators have improved, but at the same time, the obesity rate is also increasing. The prevalence of various sudden diseases has also been greatly improved.

Among college students, there are many common habits that are harmful to physical and mental health:

1, staying up late and irregular work and rest.

Under the double pressure of academic pressure and employment pressure, many college students can't work and rest regularly. Often there is no time to eat in the canteen, but snacks such as biscuits and chocolates are used instead, and a large number of college students are accustomed to take-out, which greatly increases the opportunity to contact junk food.

2. unscientific diet.

For most college students, they often don't know how to eat three meals well. And many students themselves have bad eating habits. After entering the university, without parental supervision, the problem of eating habits became more and more serious. The meal time is not fixed, and the food quality is not up to standard.
