1. British researchers have found that turning the eyeball left and right can effectively improve memory. If you want to recall something quickly, just roll your eyes back and forth for 30 seconds, which will produce good results. Researchers believe that the horizontal rotation of the eyeball can make the left and right hemispheres of the brain communicate with each other, which is very important for recalling people's memories. The researchers also found that turning left eye can stimulate the right brain, and turning right eye can stimulate the left brain. The eyeball turns back and forth from left to right, which can improve the correlation between the left and right brains, which is the key to improve memory. 2. Breathe fresh air Researchers at the University of Michigan in the United States recently found that breathing fresh air outdoors or walking in parks and suburbs can help improve memory. The results show that people who walk in the suburbs have improved their short-term memory by 20%. Researchers believe that the noise and entertainment in the city will stimulate people and affect their memory and attention. Nature can calm people down and help them concentrate. There is a saying that "high-five and kick every day, and you will never get old", which does have medical basis. The foot is considered as the "second heart" of human beings, with a large number of nerve endings. Therefore, regular kicking can not only help the blood circulation of lower limbs, but also regulate nerve activity, delay aging and improve memory. Methods: Recumbent kicking is more conducive to promoting blood circulation. Hook the foot first, then the calf will feel tight, then straighten the foot, and then the instep will feel sore. Do it alternately for two or three minutes.
