Healthy growth is not only a challenge to ourselves, but also to the adult world. Health means not only physical health, but also mental health. In order to keep healthy, one should exercise regularly and eat a balanced diet. Appropriate bedtime and adequate sleep time are necessary. These are all related to physical health. As for mental health, I think we'd better always keep high spirits, because happiness will strengthen our immune system to some extent. There is too much pressure in modern society, so it is meaningful to use a strong mind in many fields of life and study. Teenagers can get help from the adult world to protect themselves from unhealthy information and behaviors.
In a word, in order to keep healthy while growing up, everyone should take responsibility and contribute to building a healthier world for young people.
