Many people have trouble remembering things, suddenly forgetting something, in fact, memory loss is partly due to the continuous reduction of brain cells. For people who often sit in the office, memory loss is partly due to: low oxygen levels in the room. The brain of an adult weighs about 1500 grams, accounting for about 2.5% of its body weight, and its oxygen consumption accounts for 1/4 of the total oxygen consumption of the whole body. It can not be a moment of ischemia, hypoxia, only a few seconds of hypoxia will cause dizziness, blackness, gold stars, and even fainting, life-threatening. People who sit in the office for a long time, often have dizziness, memory is not as good as before, this is because of insufficient activity, poor blood flow, insufficient blood supply to the brain caused by. Whatever the reason, we all want to improve our memory as much as possible. In addition to using more impression notes to free the brain from some things, here are a few small daily actions that are good for improving memory when done regularly. 1, two legs stilted on a chair or table for a few minutes, the legs must be higher than the heart position When a person’s legs stilted higher than the heart after the blood from the feet and legs will flow back to the lungs and heart, not only can reduce the pressure on the feet and leg veins, but also can make the blood supply to the head greatly increased, so that you are refreshed. 2, shake the head shake the brain carotid artery is the pipeline of blood supply to the brain, shaking the head shake the brain can make these tissues get activity, not only can increase the blood supply to the brain, but also can reduce the possibility of fat deposition in the carotid artery vessels, but also conducive to the prevention of hypertension, cervical spondylosis. 3, stretching the body for a long time in a posture, the upper limb muscle tissue end vessels will accumulate a lot of blood, the process of stretching, precisely the process of muscle tightening and relaxation, stagnant blood is driven back to the heart, the heart gets more blood, blood transfusion to all parts of the body is also more, the brain can also get a piece of the pie. 4, good head blood circulation function helps improve memory and slow down brain aging Carry a comb, or finger combing, can improve the blood flow to the scalp. The specific practice is to open the fingers of both hands slightly, from front to back, from top to bottom, combing hair, do three or four times a day, once for three or five minutes, can play a role in improving intelligence, nourishing the brain, for patients with neurasthenia is more beneficial. 5, clench your teeth 50 times a day, can pull the head muscles, promote blood circulation in the head, enhance memory clench your teeth, saliva secretion will also increase, saliva contains parotid, has the effect of slowing down the aging process. In recent years, some people have found that saliva contains anti-cancer ingredients, can effectively prevent malignant tumors of the digestive tract. 6, more fingers can stimulate the brain fingers is the second brain, fingers and the brain connected to the most nerves, through the movement of the fingers, can effectively stimulate the brain, delaying brain cell death time. Stretch your fingers, curl your fingers, alternate between the two, or alternate between the left and right hand massage fingertips, you can also often hold a fitness ball in your hands, so that the two fitness balls in the hands of rotation. Or rice and black beans mixed together, and then pick them out separately, with these actions to exercise the hands, to strengthen or maintain the brain memory purposes. 7, open legs and drink water The brain consists of two hemispheres, the left side of the brain dominates the right limb, the right side of the brain dominates the left limb, so that the lower limb activities can stimulate the activity of the opposite side of the cerebral cortex, to play the role of brain health. Jogging, brisk walking 5 times a week, a half-hour exercise, although simple, but can improve memory. Water accounts for 50% of the brain, drink water regularly, not only can slow down aging, but also good for the brain. Drink water should master the principle of small amounts of many times, wait until you are thirsty and then drink, indicating that your body has been quite dehydrated.
