The definition of the hazard of doing homework is too broad. It's easy to narrow it down
According to your thinking, put forward the following suggestions:
1. Delay in time should be a personal break after school. Doing homework will affect the individual's suspension of study and make fatigue last. (Stress, depression, illness)
2. Delaying growth, people are social animals and need to communicate. The time occupied by doing homework will affect one's social and interpersonal skills. What is needed is practice, not theory, so we should study and apply it.
These two aspects have been expanded, which is enough.
