What are the main aspects of college students' sub-health status?

At present, most university campuses provide campus networks and broadband networks, so students who like online games, especially boys, often stay up late to play games, resulting in high spirits, inability to sleep and serious lack of sleep. Most college students don't pay much attention to their diet. When they are busy, they often eat instant noodles, or eat other low-protein and high-calorie foods, even snacks. Some girls use unscientific methods to lose weight and often skip meals, which leads to insufficient nutrition supply and decreased immunity. Some colleges and universities have heavy academic work, and the pressure brought by students' work, further studies and employment. Some college students are in a state of anxiety and tension all day, feeling that there are always endless things to do, and psychological pressure can be seen.
