The second way to stay awake in class is to listen carefully in class, which is difficult for me to do. I have to be absent-minded in class. Practice later. Pay attention to my personal experience. This is a good way to drink tea before class. I learned it in my senior year. I am allergic to tea. Drinking a little morning tea is refreshing, and it is also effective when you want to sleep in class, although it is impolite to the teacher. But learning is more important. It's even more impolite for you to sleep with the teacher in class. This is the best method I have ever used. Second, you must do some exercise after class. In winter, you can take a few breaths, exercise your muscles and stretch your muscles, which is better than drinking tea in the classroom. But if you drink tea outside, the effect is better. Running after class is good, that is, running around. In senior three, there were only stairs on the fifth floor in the classroom. Third, you must have a good breakfast. You can't have a good morning class. Don't drink milk and eat eggs in the morning. Although many people say these two are the best, it is best for people who can't sleep in the morning to eat steamed bread and drink soybean milk. Milk can help you sleep. I don't want to say more, but eggs can also increase the viscosity of blood and make you want to sleep (I have experienced it personally). But you have another problem. Eating eggs is really good for people. See for yourself, but the milk is not so good. Generally, Asians absorb 40-60% of the nutrition of milk than Europeans. I advise you not to drink milk in the morning. And it will make you want to sleep and drink soy milk. Nutrition is not much worse than milk, and absorption is much better. But you must drink milk at night, which is very good. It can not only supplement calcium, but also help sleep and digestion. Its sleep blowing effect is immediate. Fifth, when you want to sleep in class, play mobile games. Seven, in class, take the initiative to speak or talk or stand up. If you are not shy, this is the best way. Being laughed at by others, being told by the teacher, you can't sleep. If you can take the initiative to stand up in class, not only the teacher will be very happy, but also the students will admire you. After you have given everyone a good start, no one will sleep in your class. If you are funny after class, it will have the same effect. You not only improve yourself, but also help others adjust their biological clocks. This is the final result. A person's biological clock is not only related to time, but also to what classes you take and what you do. This will affect you. For example, I will be in good spirits as soon as I have a math class, but I will fall asleep soon. At this time, you should try to adjust yourself and remind yourself in the best way that you must not sleep in this class. Then you will find that your bad habits will be changed after a few weeks, and there is nothing you can do without sleeping in class. At this time, you will find that you fell down in class and the whole class is very funny. You will be proud to find yourself in good spirits. You won't sleep in any class, and your academic performance will naturally improve. There is also 1, suggesting that you must exercise properly every day. 2. Eat some dates every day or soak them in water. (Ziziphus jujuba seeds are good for sleep) 3. Soak water with Lycium barbarum every day. It is suggested to eat some red vegetables and fruits every day. 5. Drink milk and honey before going to bed. 6. It is recommended to know and eat bee pollen. 7. See if your environment has any influence. If you change it, it may be effective. 8. Analyze your lifestyle and make appropriate changes. 9. Analyze your diet and make appropriate adjustments. 10, adjust life attitude and mentality, and remain optimistic.
