The summer vacation has passed. At the beginning of the new semester, we should be prepared for the coming autumn and winter flu, gather scattered hearts back as soon as possible, form a good life and study law, pay attention to scientific hygiene in diet, and adhere to appropriate physical exercise in order to be healthy in the new semester. Because most people don't know enough about influenza, they often wait until it is seriously prevalent, but it is too late to prevent it. Therefore, schools should do a good job in the publicity and response to influenza prevention as soon as possible: First, keep the classroom air open during class, even if the weather is cold, open one or two windows to breathe. The second is to guide us to go to public places where people gather as little as possible, such as cinemas, Internet cafes and other places, so as to reduce the chance of infection. Third, we should educate us to maintain good living habits and personal hygiene in our daily lives to prevent diseases from entering the mouth; At the same time, strengthen physical exercise and actively enhance disease resistance. In addition, there is an extremely effective way to fight the flu, which is to inject the flu vaccine. An effective influenza vaccine is "Fangganling", which is recommended by the World Health Organization and passed the inspection by China Institute for the Control of Pharmaceutical and Biological Products. Clinical observation at all ages shows that "Fangganling" is a safe and effective influenza vaccine, which is suitable for people in China. During the summer vacation, our study burden is reduced, and our appetite is often greatly increased compared with that at school. When we re-enter school, because our attention is focused on our study, once we are negligent, we will have gastrointestinal dysfunction due to irregular eating time and uneven hunger, which will affect digestion and absorption and will inevitably affect our study. Therefore, we must develop the habit of eating regularly and quantitatively, which is conducive to promoting the secretion of digestive glands and the formation of regular peristalsis of gastrointestinal tract; Don't engage in strenuous mental work or strenuous exercise within half an hour before and after meals, let alone read books while eating, otherwise it will weaken gastrointestinal peristalsis, reduce digestive juice secretion, affect digestion and absorption function, and even cause gastritis or other gastrointestinal diseases in severe cases. In addition, our dietary nutrition arrangement should adapt to its physiological and psychological characteristics. In addition to ensuring the nutrition needed for growth and development, we should also take into account our heavy study tasks, and need to provide extra nutrition to make the three meals comprehensive, reasonable and balanced. Every meal should be vegetarian or mixed with grains, beans and vegetables. The collocation of staple food and non-staple food should be appropriate, so as to give full play to the complementary role of protein, improve the utilization rate of protein, and eat foods rich in vitamins and minerals to ensure the needs of the body. Autumn and winter are the seasons with frequent diseases. Usually, we should develop the hygienic habit of washing our hands with soap before and after meals, and do not eat spoiled and unsanitary food to prevent diseases from entering the mouth. After entering the school, we put most of our energy into our study. Sometimes we are so absorbed in our studies that we think it is impossible to achieve excellent results without forgetting to eat and sleep. In fact, some studies show that only long-term adherence to regular study and life can make the process of neural activity more balanced and flexible, and ensure the health of the brain and the full play of intelligence. If life is irregular, you can't calm down when you want to study, and you can't concentrate quickly when you want to do activities, then every time you do a new activity, you must make extraordinary efforts in your will, which will inevitably increase the burden on your brain, cause brain fatigue, and it will be difficult to improve your learning efficiency. Because the learning efficiency is low and the effect is poor, it will cause unnecessary trouble, which will inevitably lead to increased psychological burden. Once a vicious circle is formed, it will in turn affect the learning effect. Therefore, after entering school, we must take back the heart of flying, make scientific arrangements, strictly implement the study, exercise, entertainment and rest of the day, and let the study and rest be carried out in a coordinated and orderly manner. This helps to concentrate and naturally improve learning efficiency. Let's work together to prevent infectious diseases! Develop good living habits, establish a healthy mental outlook, and make our daily life full of sunshine and laughter!
