Why is the brain not as sensitive as before when you grow up, and you still have a headache when you think about problems? Is there any way to exercise your brain? (in order to improve learning efficiency) Memory is the reflection of past experiences in the human brain. It includes three 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. Improving memory is actually trying to avoid and overcome forgetting. 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 are ten ways to enhance your memory. 1. Attention. As long as you concentrate on your memory and eliminate distractions and external interference, the cerebral cortex will leave a deep and unforgettable memory trace. If you are distracted and concentrate on doing two things, the memory efficiency will be greatly reduced. 2. Strong interest. If you are not interested in learning materials and knowledge objects, it will be difficult to remember even if you spend more time. 3. Understand memory. Understanding is the basis of memory. Only what is understood can be firmly and permanently remembered. 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. Overstudy. That is to say, on the basis of remembering the learning materials, remember them several times more to achieve the degree of memorizing and remembering. The best degree of over-learning is 150%. 5. Review in time. The speed of forgetting is fast first and then slow. While the iron is hot, reviewing and consolidating what you have just learned is an effective means to strengthen memory traces and prevent forgetting. 6. Always remember. When studying, constantly trying to recall can correct memory mistakes, make up for omissions, and make the hard-to-remember learning content stronger. When you are free, you can often recall the objects you have remembered in the past, and you can also avoid forgetting them. 7. Combine reading, thinking, watching and listening. We can use the functions of language and visual and auditory organs at the same time to strengthen memory and improve memory efficiency, which is much better than single silent reading. 8. Use a variety of memory methods. According to the situation, flexible use of memory methods such as classified memory, characteristic memory, homophonic memory, argument memory, associative memory, interesting memory, chart memory, shortening memory and compiling outline, taking notes and cards can all enhance memory. 9. Master the best memory time. Generally speaking, 9 ~ 1 1 in the morning, 3 ~ 4 in the afternoon and 7 ~ 10 in the evening are the best memory time. Use the above-mentioned hard-to-remember learning materials, and the effect is better. 10. Use your brain scientifically. On the basis of nourishing and maintaining the brain, active rest and physical exercise, using the brain scientifically, preventing excessive fatigue and maintaining a positive and optimistic mood can greatly improve the working efficiency of the brain. This is the key to improving memory. Memory can be improved by training. At all times and in all countries, many celebrities and scholars pay great attention to exercising their memory in various ways. For example, Tolstoy, a great Russian writer, said, "I do two kinds of exercises every day, one is morning exercises and the other is memory exercises. I recite foreign words every morning to check and cultivate my memory." Tolstoy's "memory exercise" is actually a repeated "representation". As long as you "reproduce" in a planned way, your memory will be enhanced. The following methods of training memory are very effective, so you may wish to refer to them at ordinary times. Hint method-positive. Many people often sigh "I have a bad memory". On the one hand, my youth is fading away, on the other hand, I lack enough confidence in my memory. Faced with a series of foreign words or a lot of materials, some people will think: can I remember so much? In fact, it sets an obstacle to your memory. You have to cheer yourself up: "I will definitely remember." This is a positive psychological suggestion. Think about being able to recite Tang poems when I was a child; Think about the past, you carefully reviewed before the exam and got into the top few. Miss Dong, a good friend of the reporter, has been troubled by her poor memory recently and always forgets things. However, her college classmate said, "What's the difference? When I was in college, I reviewed ancient literature half a month in advance. You only raided two days in advance and scored more than 90 points, which is higher than me. " Miss Dong smiled and said, "Yes, I have a good memory. I have to cultivate it well. " Memory-time limit. Memorize numbers, names, words, etc You can exercise your memory ability within a specified time. For example, when waiting for a bus in the subway, you are required to remember several telephone numbers and addresses on the billboard before the bus comes, and try to remember them with your right brain. The next day, see if you remember it all. Don't think it's boring, but it can fully mobilize your left and right brains, prevent brain aging and improve memory, and it doesn't cost a penny. This method can be used anytime and anywhere. Of course, you can also take some customer business cards with you and remember the address and phone number on them during commuting time. Memorization.-okay. We usually contact a lot of people and things and remember a lot, but because we have few memories, many things we remember are vague or forgotten. It is a good way to exercise your memory to recall frequently and be as detailed as possible. Recently, in CCTV's "Challenge Host" program, attackers and defenders were asked to observe a model in a short time and then compete to see who remembered more. These contents are very detailed, such as the color of the model's clothes, how many T-shirts she wears, what accessories she wears, where the accessories are worn, what decorations are on her shoes, etc ... The memories of the two contestants are amazing. In fact, you can usually exercise your memory in this way. When I meet someone, I recall the style and color of her clothes, hairstyle and hair color, handbag style, fabric and so on. You can also recall the movies you saw recently. Who's in there? What happened? How did it end? Remember every shot carefully, the finer the better. Don't sigh that you are busy with work, stressed or old. These are not the reasons for "memory decline". Developing the right brain and exercising the brain in your spare time will make your memory more and more magical. Sight and hearing? How can we cultivate a pair of bright eyes that measure thousands of miles? The first 1 trick: diligent eye exercise, eye muscle fatigue, mostly excessive focus on short distance for a long time, lack of far-sighted training and exercise. Many ophthalmologists believe that this is also the main cause of myopia in children. The eyes are the qi of the internal organs. Li Fengshan, a master of Qigong, mentioned that nourishing qi should start with eye exercises. The "meditation" skill that he must practice every day is to train his eyes to do long-distance movements by staring at the distant mountains and counting the screens at close range. Office workers can find the farthest focal length in the office and concentrate on doing exercises for about 30 seconds, which can also achieve the effect. Children who are easily distracted can slowly open and close their forefinger for about 1 minute to do concentration training, Rao Huaiying suggested. Let the eyes turn slowly up and down, left and right on weekdays, which can drive the ligament muscles of the eyes to move and eliminate eye fatigue. In addition, the eyes should be normally closed, which can not only increase the secretion of tears, but also achieve the effect of "closing your eyes and nourishing your mind". Chinese medicine believes that shoulder and neck pain, dry mouth, tension, anxiety and other symptoms are prone to occur when eyes are overused. "The most fundamental way is to rest your eyes," Dr. Chen Junliang pointed out. In fact, these symptoms can be improved after proper rest. The "20/20 Law of Eye Protection" practiced in the United States for many years is worth referring to: after reading a book or computer for 20 minutes, staring at a place 6 meters away for 20 seconds can maintain your eyesight health. The second trick: a simple action to make your eyes bright: iron eyes to clear your heart: you can practice at any time when your eyes are tired. 1. The palm is rubbed and heated. 2. Put your palm flat on your eyes, exhale slowly and go back and forth several times. Worry-free method: 1 Sit still, put your hands on your lap and relax. 2. Inhale, slowly turn your neck to the left and look back as far as possible. 3. Exhale slowly and turn your neck back to the center. 4. Switch to the right and do it again. The third measure: Eye-nourishing acupoint massage that can quickly eliminate fatigue can increase eye blood circulation. When your eyes are sore, you can press the following acupoints until you feel sore. Zhu Zhu point: Jingming point on the inner side of eyebrows: the air pocket on the inner side of eyes: the temple with tears on the lower edge of eyes: Hegu point on both sides of forehead: the center point of palm (Note: people with high intraocular pressure, glaucoma, hypertension or red, swollen and hot eyes should not be massaged. Acute inflammation of the eyes, such as redness, swelling and heat pain, can be temporarily relieved by ice compress; But for general health care, it is appropriate to use hot compress. If you don't get better, please see a doctor. The fourth measure: tea eye protection Chinese medicine believes that the liver is open to the eyes, and daily tea care can alleviate eye fatigue and discomfort. Chrysanthemum, medlar and cassia seed are all eye-catching teas of traditional Chinese medicine. Lin Qiuxiang, a culinary gourmet who has studied the theory of traditional Chinese medicine for many years, is committed to keeping healthy and delicious. Every summer, he personally cooks longan, gouache and chrysanthemum tea suitable for adults and children as tea (chrysanthemum 5 yuan, 2 ounces of Lycium barbarum, longan or jujube 10, boiled with 2000cc water 15 minutes, and filtered off the dregs). She thinks it is very helpful for people who are forgetful, easily frightened and lack of effort. As for people with dry mouth, dry liver and dry tongue, they are generally called "angry" Lin Qiuxiang suggested that after the chrysanthemum tea is cooked, about 300cc of sugarcane juice can be added, which has the effect of cooling and annealing. Lycium barbarum and nuzhenzi have the effects of tonifying lung and strengthening spleen, and can also be used as general health tea. But people who are prone to blush, rage, chest tightness and high blood pressure are not suitable for drinking. Chinese medicine in Chen Junliang suggested that cassia seed, Celosia seeds and Buddleja officinalis (available in Chinese medicine shops) that can clear away heat and liver fire should be soaked in water. If the blushing condition doesn't improve, you'd better see a doctor. The fifth measure: vegetables and fruits, eating vitamins A and B and antioxidants in vegetables and fruits with good eyesight are indispensable nutrients for establishing good eyesight. Foods rich in vitamin A: Amaranth, lily, sherry red, sweet potato leaves, medlar, nine-story pagoda, papaya, mango, green tea, etc. can provide the nutrition needed by the retina. If the retina is compared to a camera negative, vitamin A is the photosensitive substance on the negative, which is responsible for absorbing blue light and preventing the sensitive area of the retina from being damaged by light. General dry eye is also caused by lack of vitamin A. Reading and using computers will consume a lot of vitamin A, so you should eat more foods containing β-carotene, such as cod liver oil, sweet potatoes, carrots, liver, melons and dark green vegetables. "Because beta-carotene will be converted into vitamin A in the body", intensive listening means listening to tapes or MP3 (which can be materials such as VOA) while dictating as many sentences as possible.
