You said that you entered the society and were sleepy when you were studying. I see. But students who go to school will also feel sleepy when they study. What happened?
It is normal for students to be sleepy when studying. To improve it, we can try the following points: first, strengthen self-drive, that is, the motivation of learning. Let the child have a goal and pursuit in mind, not grades and rankings, but to inspire him with things he loves and is interested in. For example, he likes to travel. It can be said that if you get into a good university, you will have the opportunity to go to more interesting places. Second, stand for a while. Many high school students will consciously stand up after reading. Third, have a rest, such as going to exercise. The child is sleepy, probably because he has been reading for a long time. Fourth, to improve his interest, teachers or parents should start with the books he is interested in and form the habit of reading first.
