In life, in movies, we have heard of hypnosis more or less. Hypnosis seems to be a very magical thing. It can read other people's memories and even delete other people's memories. Can hypnosis really change people's memory? Can memory be controlled during sleep, and the response to fear can be inhibited? How can we improve sleep efficiency in daily life?

1. What methods can be used to improve sleep efficiency in daily life?

The so-called sleep efficiency means that the real time asleep is the numerator, and the time spent in bed is the denominator. Some people may go to bed at 9 o'clock to 12 o'clock and fall asleep at 6 o'clock, some people go to bed at 12 o'clock and fall asleep at 12 o'clock, and also wake up at 6 o'clock, the sleep efficiency is different. Therefore, we recommend that, first, if you want to improve sleep efficiency, you should not go to bed when you are not sleepy, because the more you lie down, the more anxious you will be. Second, do not eat too full 4 hours before going to bed, and do not eat 2 hours before going to bed. If you are hungry, you can drink some milk or light fruit, because digestion will also affect our sleep efficiency. Third, you must exercise properly during the day. It is not recommended to exercise vigorously 4 hours before going to bed, and it is not recommended to exercise 2 hours to 1 hour before going to bed. Therefore, it is best for us to exercise at noon, morning or evening. If you exercise too much, it will also affect sleep, as if you can't fall asleep repeatedly, so we emphasize moderate exercise. Drinking and smoking can also affect sleep structure. If you drink coffee, it is recommended to go to morning before 3 pm.

2. What is the relationship between sleep and the preservation of memory and the cleaning of brain garbage?

Why is sleep important to our brain function? Only when you fall asleep can some of the metabolic waste of the brain be cleared out. If you don’t sleep all night, your brain will become drowsy the next day, because there are some metabolic waste toxins stored in the brain, which will affect our brain function, memory decline, and bad temper. Only when sleeping can we clear the body through our blood circulation. Why sleep is also important to children's learning and growth? Only when we sleep, what we learn can be saved by memory through sleep. If sleep is deprived, academic performance will decline, and he cannot remember many things.

3. Why can I remember the process of sleeping?

Only when sleeping, part of our brain is at rest and part of it is activated. During the day, our brain will have to receive a lot of information and is disturbed. Some memory functions are not good. Only after sleeping, a lot of your information does not enter the brain, but some functions of the brain are activated. It also processes and memorizes the information during the day.

4. Is it possible to regulate memory and inhibit the response to fear during sleep?

Our brain may input some unpleasant things during the day. For example, when I was in a car accident, the car accident was very harmful to me, the sound of the car accident at the time, or maybe the moment I saw the car or the scene reminded me of the pain . Now research has found that when you are sleeping, you put the sound of the car or the sound of the scene to you, and then the pain may reappear, and after it occurs, measures will be taken to erase these painful memories from your mind. This requires special and special intervention. Now studies have found that this is feasible, but in fact, the treatment of patients has not yet started on a large scale, and some further research may be needed. But you have all heard of hypnosis. Hypnosis can evoke some pain in others, and the reason is similar.

5. Do you give some sleep advice to white-collar workers or students?

White-collar workers are very busy with work, life pressure is great, spare time is also very rich, and nightlife is also very rich. But the most important thing is that we don't overdraw too much, and ensure that we have enough sleep under any circumstances, so that we may have enough energy to live, work, and develop ourselves. Overdraft of sleep means overdraft of health. The economic conditions are good but the loss of health is not worth the loss.
