Dear teachers and students:
Hello everyone! Today, the school arranged for me to discuss hygiene and health with you. I feel very honored. When I was four years old, I was sick, and my family and I were in pain. So now I deeply feel that health is the greatest wealth in life. Only when I am healthy can I have a happy life. Don't you think so?
There will be a quiz after today's study. As long as you pay attention to the class and remember by heart, I will ask two related questions after today's study. As long as you answer correctly according to today's study, you will have a chance to get a beautiful gift. (display)
Let's start learning:
Everyone wants to be healthy. So, how can a person be healthy? Some students may say that no illness (no dizziness, no body heat, no itching and no pain) is health. This is actually a one-sided understanding of health.
According to the World Health Charter, health includes not only physical absence of disease and infirmity, but also mental health, good social adaptability and moral health. Among them, mental health has been paid more and more attention. A scientific examination of the psychological status of 30,000 randomly selected primary and secondary school students by the National Mental Health Education Research Group found that 32% of the students had psychological abnormalities. This shows that some primary school students do have mental health problems, which is an unavoidable and indisputable fact.
Today I want to talk about these two aspects:
Students, first of all, talk about health knowledge: spring is here, and I want to focus on the prevention of influenza, that is, influenza. Maybe you will ask, the flu is what we call a cold. In fact, influenza and cold are not the same thing. A cold is usually caused by a common respiratory virus, which is not too urgent, mild and gets better quickly. Influenza is caused by influenza virus, and it is spread by sneezing, coughing and droplets coughed up by talking. The onset was very urgent, and I was afraid of cold at first, and then it was hot, and my body temperature quickly rose to 39-40℃, or even higher. At the same time, the flu is accompanied by obvious symptoms, such as headache, body aches and weakness. If the condition is serious, it will be infected repeatedly, and when it is serious, it will be complicated with viral myocarditis. We must strengthen prevention.
So how can we prevent the flu? The doctor told us that we should try our best to avoid talking to people with flu. We shouldn't use clothes and toys that come into contact with patients. During the flu epidemic, children should try not to go to public places, such as cinemas and shopping malls. After suffering from influenza, patients should stay in bed at home, drink plenty of water, strengthen nutrition, prevent fatigue and don't go to school. We should also strengthen regular physical exercise in peacetime.
Hygienic habits of disease prevention in spring
In spring and summer, the temperature changes greatly. In this climate, human respiratory tract is vulnerable to pathogenic bacteria and viruses. The digestive tract is easily affected by the hot and cold diet, which leads to disharmony between the spleen and stomach, and irregular dressing is easy to catch a cold and get sick.
Therefore, it is very important for teenagers to develop good hygiene habits. I can sum it up in 20 words: Pay attention to hygiene/eat reasonably/get enough sleep/exercise moderately/relax/
Prohibition of spitting
Sputum contains thousands of germs, which can survive for a few days to dozens of days in daily environment, and some of them spread around with the air, causing the spread of various diseases. Everyone should consciously spit on a piece of paper and throw it into the dustbin. Don't sneeze in front of others. Cough may splash droplets and saliva on others, thus spreading germs and making people sick. At this time, cover your nose and mouth with a handkerchief or paper towel and apologize to others afterwards.
Don't litter, rubbish often contains all kinds of bacteria and viruses, which will continue to breed in the daily environment, so you can't litter everywhere because of disgust.
Wash your hands frequently.
Every time you go out, you may come into contact with doorknobs, handrails, counters, telephones, etc. to pollute your fingers and palms. , so pay attention to wash your hands and eliminate hidden dangers. Wash your hands carefully with soap and tap water before eating every time to form good habits.
Pay attention to "light" and "dry" in diet.
Eat more fresh vegetables such as cucumbers, tomatoes, spinach and lettuce this season. Drink more chicken soup (chicken soup is rich in protein, which can enhance the body's resistance) and eat more tomatoes. Tomatoes are rich in vitamin C, which can help white blood cells to enhance their resistance to viruses (bacteria), thus preventing colds.
Ensure adequate sleep time: primary school students should sleep 10 hours every day, and it is best to rest for one hour at noon.
Increase outdoor sports
Outdoor activities increase the chances of exercise, and outdoor fresh air can reduce the chances of getting sick. Keep a relaxed mood. Try to avoid nervousness, irritability, anger and even anger, which will affect internal organs and lead to diseases.
