Well, I often read books at night in the third grade, and the upstairs method didn't have much effect after a long time.

I used almost all the methods that year.

When you are really sleepy, it is estimated that nothing can be done. I tested them with compasses. ....

A more effective method:

1. Get some sleep first. You can sleep for half an hour, preferably not more than an hour, otherwise you will be more sleepy and can't stand it at all. Sleep below first, you can keep your energy to read.

It's best not to drink too much coffee, it will do harm to your health. You can drink some ice, but you'd better not try it in winter. Or prepare a basin of ice water. If you feel sleepy, put your hand in or wash your face.

Before reading a book, it's best not to watch TV, read novels, or do fascinating and addictive things, such as playing games. I don't want to read like that.

You can wear headphones to play music when reading. It's not easy to get sleepy if there is sound in your ears. Of course, it's best not to choose something too lyrical, lest you regard it as a lullaby. .....

You can wear less clothes (in winter) or tight clothes to make yourself feel uncomfortable, so you can't sleep.

6. When you are sleepy, try to write with your left hand and try to write a line, which will help to eliminate fatigue. I tried this. I was sleepy in class once. It is very useful for me to do so.

I think the above items are quite useful. I wonder if it will help you.

Of course, it's best not to stay up late. The body can't stand it after a long time.
