The habit of keeping your brain healthy

1. Don't use your brain for a long time. Psychological research has found that when healthy children use their brains for 30 minutes continuously and their blood sugar concentration is above 1.20mg, their brains react quickly and have strong memory. When they used their brains continuously for 90 minutes, their blood sugar dropped to 80 mg, and their brain functions were still normal. Continuous use of brain 120 minutes, blood sugar dropped to 60 mg, slow response, poor thinking ability. If you continue to use your brain for 2 10 minutes, your blood sugar will drop to 50 mg. At this time, you will feel dizzy, have a headache and temporarily lose your ability to work. So it is not advisable to use your brain for a long time. It is generally believed that the continuous time for primary school students to do homework or read books at a time should not exceed half an hour to 1 hour. 2. It is advisable to use the five senses, hands and brain to participate in learning. It is found that learning the same content can be accepted by 20% if you only use vision, 15% if you only use hearing, and 50% if you use audio and video at the same time. This discovery shows that using a variety of sensory organs to participate in learning can obviously improve learning efficiency. 3. Different learning contents should be staggered. When children are learning, different learning contents will form excitement points in different areas of the cerebral cortex. If you study arithmetic, you can form an exciting point in a certain area of the cerebral cortex; Learning English forms an exciting point in another area of the cerebral cortex. Therefore, if you study the same content for a long time, it will inevitably increase the load of nerve cells in a certain area of the cerebral cortex. If you can learn different contents alternately, you can let nerve cells in different areas of the cerebral cortex work in turn, get enough rest and learn better. 4. Make full use of the "best brain time". Everyone has the best time to use his brain every day. "Some children have a sharp brain in the morning and the best memory. Some children have the clearest mind at night and the best learning effect. Parents should understand and make full use of their children's "best brain time" to improve their learning effect. 5. Keep enough sleep. Sleep is the main way for the brain to rest. Adequate sleep can make the brain eliminate fatigue and ensure the normal work of the brain. Therefore, parents should arrange their children's sleep time reasonably, let them sleep well, and don't let them burn the midnight oil, so as not to affect their health. 6. Pay attention to physical exercise and physical activity. Physical activity can promote the metabolism of brain cells and eliminate brain fatigue, especially physical exercise, which can improve the response ability and flexibility of the nervous system and help children improve their eyesight, hearing, observation and thinking ability. Parents should educate their children not to ignore physical exercise and manual labor, let alone to oppose learning with physical exercise and manual labor. They think that physical exercise and proper participation in manual labor are a waste of time and will affect learning, but it is just one of the important ways for children to use their brains scientifically. 7. Proper diet and adequate nutrition. When children study hard, they will consume a lot of nutrition and oxygen. Their brains will be damaged if they are not replenished in time. Reasonable diet, adequate nutrition and rich protein, vitamins and minerals can ensure the normal metabolism of brain nerve cells. Therefore, children should eat protein of animals and plants, such as meat, poultry, seafood and bean products, eat more fresh vegetables and fruits, and supplement vitamins and fructose. 8. Provide a good learning environment. The brain is the organ that consumes the most oxygen, and sufficient oxygen can improve the working efficiency of the brain. Therefore, we should pay attention to the fresh air and often open the window for ventilation. Psychological research shows that the brightness of light will affect children's judgment ability, and bright light can make people awake. 9. Give children space and time. It is necessary to free children's space, free children from the "three points and one line", and get in touch with society as much as possible, understand society and adapt to society. On the surface, it seems that there is less study time, but in fact, children have more learning content, faster intellectual development and higher learning enthusiasm, which is often misunderstood or ignored by many parents. There are many ways to use the brain scientifically, but there is only one center, that is, we must act according to the laws of human brain activity and not violate the hygiene of using the brain.
