"Four Diligences": Wash hands, bathe, manicure and clean frequently. Hands often touch here and there, which is easy to get dirty. If you buckle your nose, rub your eyes and touch your mouth with dirty hands, it will bring germs into your body and cause diseases. So be sure to wash your hands frequently. Skin is the first line of defense to maintain health. Frequent bathing can remove dust and bacteria from hair, skin surface and pores in time, and prevent sores, tinea and scabies. It is easy to hide dust, germs, viruses and parasites under your nails, so you should always cut your nails. In addition, poor sanitation is easy to spread diseases. Clean frequently and keep indoor and outdoor clean. "Two noes": Do not use sanitary ware (such as towels, cups, etc.). ) and don't litter. "Five good": good mental adjustment, good living arrangement, good diet adjustment, good clothing and good health care. Adjust the mentality: just keep a good mood. In this way, people not only feel comfortable, but also enhance their immunity to diseases. We should attach importance to science, not superstition, and use science to guide our lives. Arrange your own life: arrange a certain time for study, physical exercise, housework and other activities every day. And pay attention to the rules of life.

Teenagers are in the best stage of physical development and learning cultural knowledge. Most parents want their children to be healthy, study well and achieve something in society in the future, which requires a strong body and a smart mind. Good living habits are good for the brain. First, have a good breakfast. There has always been a saying that breakfast is good, lunch is full, and dinner is few. But because the morning is the most stressful time, some children are lazy and have no time to eat breakfast. This is very harmful to the brain, because skipping breakfast leads to low blood sugar and insufficient nutrition supply to the brain. Morning is the time when homework is the most, and the energy needed by the brain is not supplied, which will affect homework and brain development in the long run. Fresh milk is best for breakfast. It not only contains high-quality protein, but also contains lecithin necessary for brain development. Second, ensure adequate sleep. Sleep is a period of rest and adjustment for the brain. Sleep can not only make the cells in the cerebral cortex not fail, but also replenish the consumed energy and achieve a new balance in the process of excitement and inhibition in the cerebral cortex. Good sleep can improve memory. Teenagers should ensure 8 hours of sleep every day. At the same time, you should be careful not to cover your head when you sleep, because when you sleep with your head covered, with the continuous increase of carbon dioxide concentration in the quilt, the oxygen concentration will continue to decrease, and the brain will not get sufficient oxygen supply, which will cause great harm to the brain for a long time. Third, drink more water. Water is the most important part of the human body. Studies have found that insufficient drinking water is an important reason for the accelerated aging of the brain. Teenagers should drink at least 8 glasses of water every day to ensure their physical needs. Take part in physical exercise. Exercise can not only make bones and muscles strong, but also promote the development of brain and internal organs. Fourth, don't use your brain when you are sick. When you are in poor health or suffering from various acute diseases, you should rest. At this time, if you still insist on learning to use your brain, it is not only inefficient, but also easy to cause brain damage. School health publicity materials.
