Hunger improves learning and memory. Recently, a study by American scientists confirmed that hunger can improve people's learning ability and memory and make them smarter. This is because, when people are hungry, the gastric mucosa will produce something called. The hormone "ghrelin" will enter the brain through blood circulation, which has the function of improving brain function. A scientific study in Japan also found that long-term satiety can lead to premature aging of the brain. Memory is the reflection of past experiences in the human brain. It includes four basic processes: memory, retention, reproduction and recall. Its forms include image memory, concept memory, logical memory, emotional memory, sports memory and so on. ? The enemy of memory is forgetting. The essence of improving memory is to avoid and overcome forgetting as much as possible. As long as you exercise consciously and master the laws and methods of memory in learning activities, you can improve and improve your memory. ? Here's how 10 can enhance memory:

1. When paying attention to centralized memory, as long as you concentrate, concentrate, and eliminate distractions and external interference, the cerebral cortex will leave a deep memory trace, which is not easy to forget. If you are distracted and concentrate on doing two things, the memory efficiency will be greatly reduced.

2. If you are interested in learning materials and knowledge objects, it will be hard to remember even if you spend more time. ?

3. Understanding Memory Understanding is the basis of memory. Only what is understood can be remembered for a long time. It's not easy to learn by rote. For important learning content, if we can combine understanding with reciting, the memory effect will be better. ?

4. Over-learning means memorizing the learning materials several times on the basis of memorizing them, so as to reach the level of memorizing them. ?

5. The speed of reviewing and forgetting in time is fast first and then slow. Strike while the iron is hot and review and consolidate in time are effective means to strengthen memory traces and prevent forgetting. ?

6. When you often recall learning, you can try to recall constantly, so that mistakes in memory can be corrected, omissions can be made up, and the difficulties in learning content can be remembered more firmly. When you are free, you can often recall the objects you have remembered in the past, and you can also avoid forgetting them. ?

7. Audio-visual combination can use the functions of language and visual and auditory organs at the same time, strengthen memory and improve memory efficiency. Much better than a single silent reading.

8. A variety of means According to the situation, flexible use of memory methods such as classified memory, chart memory, shortening memory and compiling outlines, taking notes and cards can enhance memory. ?

9. The best time is usually 0 ~ 1 1, 3~4 pm and 7~ 10 at night, which is the best memory time. Use the above-mentioned hard-to-remember learning materials, and the effect is better. ?

10. Scientific use of the brain can greatly improve the working efficiency of the brain, prevent excessive fatigue and maintain a positive and optimistic mood on the basis of ensuring nutrition, active rest and physical exercise. This is the key to improving memory. ?

But I don't recommend deliberately not eating in order to forcibly enhance memory. This is just an experiment made by scientists in a specific environment.
