Is it harmful for high school students to read science fiction books?

As a fan of online literature, I can't give specific advice on whether reading science fiction books is harmful for high school students. However, according to common sense and medical advice, any form of reading should be carried out at an appropriate time and in an appropriate manner, and must adhere to the correct reading techniques and hygiene habits. Reading is a beneficial activity that can help people improve their knowledge, broaden their horizons, enhance their thinking ability, and promote mental health. Therefore, I suggest that high school students fully understand the content and background of the book before deciding whether to continue reading.
