2. Dendritic branches mainly occur during sleep, so sleep is particularly important for children's growth and learning; The brain needs deep physiological rest in order to exercise its function better; Sleep enhances procedural memory and performance, and balances emotional memory; Make the brain more efficient by clearing some unnecessary information during sleep; Sleep can give the brain time to reorganize circuits, remove unimportant mental fragments and deal with emotional events (Freeman 1995).
Memories solidify in sleep. Born and others believe that learning information is first stored in the hippocampus, then activated during sleep, and then transferred to the cortex, forming long-term memory (exposure to the scent of roses during the day and at night can promote memory) (Rasch B., et al. Science, 315.1426-/kloc-0
Lack of sleep may not affect simple repetitive memory, but it has a great influence on the completion of learning tasks that require endurance, creativity and high-level problem-solving ability. Sleeping less than two hours will significantly affect the ability to remember information the next day. The more complicated the learning task, the greater the savings in sleep. Sleep enhances procedural memory and performance, and balances emotional memory; Bob Stickgold of Harvard University (1997).
Sleep deprivation is closely related to depression; Lack of sleep leads to slow response and inattention; Sleep deprivation leads to the retention of negative speech, which leads to negative attitudes and opinions; There are three important factors to promote learning, achievement and memory: 1 moderate stress, good sleep, and positive emotions and emotions.
Therefore, to ensure adequate sleep, generally about eight hours a day, take a nap during the day, and don't sleep with your head covered, so as to avoid the increase of carbon dioxide concentration in the quilt and the continuous decline of oxygen concentration, and inhaling humid air with high carbon dioxide concentration for a long time is harmful to the brain.
3. Some nutrients are closely related to the cognitive function of the brain: iron, zinc, manganese, selenium, folic acid, B 1, B2B6,&; B 12, ω-3 fatty acids, choline, acetylcholine, etc.
The concentration of attention depends on the free transmission of information between brain cells, and the activities of brain cells need oxygen carried by blood sugar to support them. Therefore, keeping the brain focused and ensuring a stable energy intake every day is the first step. But this alone is not enough: the transmission of information from one brain cell to another needs nerve fibers to bridge, and these fibers, like wires, need to be protected by nerve sheaths to insulate them from the surrounding environment, so that the transmitted content will not be disturbed; The nerve sheath consists of a lipid substance called myelin.
Among the nutrients we ingest from nature, Omega-3 fatty acids help to synthesize this myelin sheath. Common sources of Omega-3 fatty acids include fish, walnuts, pumpkins and flaxseed. Therefore, in order to maintain attention, a regular and adequate diet every day is essential; When you want to eat snacks, you may wish to give priority to foods rich in Omega-3 fatty acids, such as walnuts and pumpkin seeds.
Both students and themselves should pay attention to breakfast, pay attention to drinking water, balance nutrition, and avoid smoking and alcohol.
Pay attention to overcoming some bad habits: long-term satiety. Modern nutrition research has found that after eating too much, the substance called "fibroblast growth factor" in the brain will increase significantly. Fibroblast growth factor can increase capillary endothelial cells and fat, and promote atherosclerosis. Long-term satiety will inevitably lead to cerebral arteriosclerosis, premature aging of the brain and mental retardation.
It's mellow and sweet. Alcohol can weaken the inhibitory ability of cerebral cortex, so people who drink alcohol will feel top-heavy, unstable and unresponsive. Alcoholism is particularly harmful to the brain. Sweet food will damage appetite, reduce appetite, reduce the intake of high protein and multivitamins, lead to malnutrition and affect brain development.
Disdaining breakfast and skipping breakfast will make the body and brain unable to get normal blood sugar supply. Insufficient nutrition supply to the brain is harmful to the brain over time. In addition, the quality of breakfast is also closely related to thinking ability. According to research, children who eat high-protein breakfast generally have longer optimal thinking in class, while vegetarian children's energy drops relatively quickly.
4. Emotion and emotion are people's attitudes, experiences and corresponding behavioral responses to objective things. Emotion and emotion are mediated by personal wishes and needs. When objective things or situations meet the needs of individuals, individuals will have positive emotions; Otherwise, it will bring negative emotions. For example, individuals are happy because their works won the prize, and feel pain because of the loss of their loved ones. Expression of emotions: happiness, anger, pain, hatred, fear, etc. Emotion has an influence on the performance of different difficult tasks.
The classroom must be a positive environment; Teachers need to cultivate students' positive attitude. Laughter is the teacher's duty; More positive thoughts and humor in class; Pay attention to the inquiry, selectivity, periodicity (10 minute principle) and uniqueness of the brain in teaching; Teachers must use a variety of means to teach and successfully apply them to all students; Appropriate learning goals and pressures.
Remember, exercise, breathing exercise and humor are not wasting our precious study time.
5.Glaser et al. (1985, 1984) found that people with high self-reported loneliness have lower NK activity and higher antibody level to herpes virus than people with low self-reported loneliness. Social support accelerates wound healing. Low social support will lead to bad psychological experiences such as loneliness and helplessness, thus reducing the level of mental health. The lack of social support is closely related to depressive symptoms. For example, if children lack social support from their parents, they will obviously increase the risk of depression and anxiety.
Summing up at school can be done through "communication+self-introduction; Group games (for example); Listen to your heart; Admire each other; Pay attention to friendship and affection to increase students' socialization. From the foregoing, we find that behavior has a great influence on the brain and cognitive activities. Let's take appropriate actions, keep a healthy brain, improve learning efficiency and live a healthy, happy and happy campus life.
