1. Eat foods rich in lecithin. Acetylcholine is the "lubricant" of the brain, which can make the brain more active. Lecithin can be converted into acetylcholine. Therefore, eating more lecithin-rich foods such as peanuts, soybeans, and edamame will help improve memory. 2. Get more sleep. You read that right. Sleeping can make you smarter. The brain continues to process various memories after people fall asleep, and when you wake up, you will find that your memory is better. 3. Regular exercise. According to the theory in the book "The Revolutionary New Science of Exercise and the Brain", exercises such as Taekwondo and dancing can improve brain coordination. Even if you stay at home, you can take the Wii motion controller and dance in front of the TV screen to exercise your brain. 4. Play an instrument. Pick up your guitar and play the drums. It doesn't matter if you don't play well. The key is that playing an instrument can make the part of the brain that controls memory and coordination more active. 5. Eat with eyes closed In order to use your brain consciously, you can block some information, such as visual information. Close your eyes and rely on your other senses to find food and bring it to your mouth. This can stimulate the senses of touch, taste and smell, thereby enhancing the function of related areas in the brain. 6. Use your left hand to do things. Most people are accustomed to using their right hand. The movement of the right hand is controlled by the left brain, so people usually use the left brain more. If you consciously let your left hand do something, it will be a new stimulation for the brain and help develop your right brain. 7. Drinking yogurt with probiotics is not only good for the gastrointestinal tract, but also helps control anxiety, allowing the brain to show stronger abilities in emotional and memory processing.
