Lecture on health knowledge

The smooth development of health knowledge lectures can not be separated from an excellent speech draft. The following are the health knowledge lectures I collected and arranged for you. I hope it helps you. Welcome to read the reference study!

Lecture on health knowledge 1 The cold wind made us shiver, and the epidemic of diseases threatened our health. How can we strengthen self-care and grow up happily?

Let's talk about the prevention and treatment of liquid in winter and spring. Medical experts point out that some common-sense measures are effective ways to prevent influenza and should not be ignored because of simplicity. Prevention methods are:

1. Open the window indoors for ventilation, keep the air fresh, dilute it with proper amount of vinegar and water, and then heat and evaporate it to disinfect the indoor air;

2. Go to public places less and use masks reasonably;

3. Wash your hands frequently;

4. Don't use towels, handkerchiefs, tableware, etc. Being with infected people;

5. Exercise improves the body's resistance and cold resistance.

6. Don't eat all kinds of food and drinks bought by stalls, and don't drink raw water.

As we all know, highly pathogenic avian influenza spread around the world this winter, and millions of live birds were killed, and dozens of deaths have been found. According to medical experts, once infected with bird flu, there is almost no possibility of cure, but the disease can also be prevented. The method is:

Wash your hands frequently. A few days ago, experts from the World Health Organization said that the current bird flu epidemic is relatively stable, so people in China need not be too nervous. But pay attention to personal hygiene and wash your hands frequently. "Smelly soap" works best, but a little hand sanitizer will do.

2. Chicken and eggs should be cooked and eaten. Eggs and chicken must be cooked before eating, and influenza viruses generally cannot survive at 70 degrees Celsius or above. In fact, eating cooked poultry will not be infected with the virus. Experts remind: friends should not buy half-cooked boiled chicken, drunk chicken, half-cooked duck and goose and other poultry food, and remind friends who like to eat half-cooked eggs that it is better to eat less! In addition, friends, please go to regular shops and commercial outlets to buy poultry meat that has undergone strict quarantine, and don't slaughter poultry for consumption.

3. Pay attention to disease prevention. Because there is no effective vaccine at present, and the high incidence of respiratory diseases is in winter and spring, experts remind that a healthy lifestyle is very important to prevent diseases. Strengthen physical fitness, pay attention to physical exercise, and do more exercise, 2-3 times a week for half an hour each time. At the same time, we should ensure sleep and don't overwork.

Please pay attention to high temperature antivirus. Avian influenza virus is sensitive to organic solvents such as ether and acetone, high temperature and ultraviolet rays. Heating at 60 degrees 10 minute, heating at 70 degrees for several minutes, direct sunlight for 40 to 48 hours, and using common household disinfectants can kill avian influenza virus.

5. Don't go to the poultry market. World Health Organization officials and Thailand's Ministry of Health believe that/kloc-children under 0/2 are the most vulnerable to infection! Please don't touch and hug birds and animals, let alone go to the poultry market.

6. Don't travel to epidemic areas. Experts advise tourists to avoid areas where bird flu has broken out. At present, the virus source of avian influenza outbreak has not been clearly defined, and the transmission route of the virus has not been clearly defined, whether it is "bird-human" or "bird-human-human". If you have to go to an epidemic area, please try to stay away from places with poultry, such as chicken coops.

7. Don't touch live birds. If you work and live in an epidemic area, please remember that a, feces and secretions are one of the transmission routes of avian influenza; B, remember to wash your hands immediately after contact with poultry, and wash your hands and forearms thoroughly with clear water; C, try to avoid contact with live birds.

8. Don't despise pets. Pet lovers, especially friends who keep birds, should be on high alert. Birds are susceptible to avian influenza virus. Even if you are not in the bird flu epidemic area, for safety reasons, please pay attention to disinfection when removing bird droppings, ensure ventilation and hygiene in the cage, wash your hands and pay attention to personal hygiene in time after contacting birds, and contact the veterinarian in time after birds get sick.

Students, the most precious thing in life is life, and the greatest happiness is health. Let's start from every little thing around us, form a good habit of paying attention to safety and hygiene, and let the danger leave us! May happiness be with us forever!

Health knowledge lecture 2 Spring and summer are the seasons when all kinds of viruses and bacteria are easy to breed, multiply and infect.

1, how to pay attention to food poisoning

2. Pay attention to flu prevention measures.

How to pay attention to food poisoning

Food poisoning refers to an acute subacute disease that occurs after eating food containing biological and chemical toxic and harmful substances by mistake or taking toxic and harmful substances as food. This is a frequent disease, which will cause serious damage to human health and life. Teenagers are in the stage of physical growth and development, so it is very important to prevent food poisoning and ensure healthy growth.

First, understand the types of food poisoning. Food poisoning is mainly divided into bacterial food poisoning, mycotoxin food poisoning, chemical food poisoning, plant food poisoning and animal food poisoning. The common food poisoning in daily life is mainly bacterial food poisoning. In addition, bean poisoning, soybean milk poisoning, and poisoning by eating toxic and harmful substances also occur from time to time.

So how to prevent food poisoning?

According to the characteristics of children and adolescents, we should mainly do the following:

1, develop good hygiene habits. Wash your hands before and after meals. Bad personal hygiene habits will bring pathogenic bacteria into food. For example, if the hands are stained with pathogenic bacteria and then food is taken, the contaminated food will enter the digestive tract, leading to bacterial food poisoning.

2. Choose fresh and safe food. When buying food, we should pay attention to check its sensory attributes to see if there is corruption. Small food, in particular, should not only look at its colorful appearance, but also look at its production date, shelf life and whether there are signs such as factory name and address. Can't buy expired food and products without factory name and address. Otherwise, once there is a problem, it cannot be pursued.

Food should be thoroughly washed before eating. Especially raw vegetables and fruits should be cleaned; The food to be heated should be thoroughly heated. For example, kidney beans and soybean milk contain saponins and other toxins, and incomplete heating will cause poisoning.

4. Try not to eat leftovers. Heat it thoroughly if you want to eat it. Leftover meals, desserts, milk, etc. They are all good media for bacteria, and incomplete heating will cause bacterial food poisoning.

5, do not eat moldy food, sugar cane, peanuts, these mycotoxins can cause poisoning.

6. Be wary of eating toxic and harmful substances by mistake. Containers containing disinfectants, pesticides or rodenticides must be properly disposed of after use to prevent poisoning due to drinking water or misuse.

7. Don't buy food from vendors without hygiene license.

8. Drinking drinking water that meets the hygiene requirements. Don't drink raw or unclean water.

9, advocate physical exercise, enhance the body's immunity, resist the invasion of bacteria.

As long as we start from the above aspects, seriously study food hygiene knowledge, master some preventive methods and improve self-hygiene awareness, we can minimize the risk of food poisoning, prevent food poisoning and protect children's health.

Pay attention to the measures of influenza

Summer and autumn are the seasons with frequent infectious diseases in schools. Schools are crowded places, and students are prone to infectious diseases. In order to ensure the physical and mental health of students and the normal teaching order of the school, combined with the actual situation of our school, the following decisions are made, and students are requested to follow them:

First, strengthen the morning check-up and seek medical advice in time.

Strengthen morning check-up to ensure "early detection, early isolation and early treatment". If students are found to have flu-like symptoms such as fever, the class teacher and the Health and Health Commission should do a good job of registration and reporting, and mobilize students to see a doctor in time, suspend classes, and isolate the severely ill until they are fully recovered.

Second, open the window for ventilation.

Pay attention to the ventilation of classrooms, dormitories and other public places, and ventilate for at least 2 hours every day to keep the air fresh and clean; After class, students should go outdoors to breathe fresh air.

Third, wash your hands frequently.

Students must develop good hygiene habits and pay attention to washing their hands frequently. The research results show that cold virus can survive for 70 hours in hands. People with colds will stick the virus to their hands when they blow their noses and pick their nostrils. If healthy people shake hands with patients in public places or touch things touched by patients, they will carry cold virus on their hands. So it's important to wash your hands frequently.

Fourth, combine work and rest.

Pay attention to the combination of work and rest, ensure at least 8 hours of sleep every day, and increase the disease resistance. Studies have shown that people will produce a substance that can improve immunity during sleep. Therefore, it is very important for cold patients to ensure adequate sleep.

Five, less to public places, during the influenza epidemic, should be less to public places. Minimize going to crowded places and reduce the chance of infection. Wear a mask when in contact with flu patients.

Sixth, pay attention to the details of life

Increase or decrease clothes according to temperature changes, and improve human immunity through a reasonable and balanced diet. Pay attention to cold and warmth in summer and autumn, and try to reduce the inducement of flu. Although you sweat less in winter, you should drink more water and eat more fruits and vegetables. High-fat, high-protein and high-sugar diet will reduce human immunity. If the diet is too salty, it will reduce saliva secretion and lysozyme secretion in the oral cavity, and reduce the secretion of disease-resistant factors such as interferon, making it easy for cold viruses to enter the respiratory mucosa and induce colds. Therefore, we advocate a light diet. Change your toothbrush frequently. People use it every day. If they have a virus, they are easily infected again and again. In addition, the toothbrush is often in a wet state, and germs are easy to breed, which is extremely unfavorable to health. Keep your feet warm, because your feet are sensitive to temperature. If your feet catch cold, it will reflexively cause vasoconstriction of nasal mucosa, making people vulnerable to cold virus. At the same time, advocate cold water to wash your face.

Seven, strengthen physical exercise, enhance disease resistance.

Students who have been sitting in the classroom for a long time should increase outdoor exercise, improve their study tension, strengthen their physique and enhance their disease resistance.

Eight, disinfection and terminal disinfection at any time

Disinfect the sick students' classes at any time/at the end of the period, and disinfect the classrooms during the epidemic (peracetic acid, lactic acid, ultraviolet rays, vinegar, etc.). Vinegar fumigation has a good effect on preventing influenza. The dosage of vinegar is 5- 10 ml/m3, diluted twice with water, and heated on the stove until the vinegar evaporates, once a day, for 3 days. The classroom is cleaned by wet method every day, and the ground is disinfected during the epidemic.

IX. Drug Prevention

At present, it is recognized that amantadine drugs can prevent influenza A, and its mechanism is to inhibit the virus from entering upper respiratory epithelial cells. However, these antiviral drugs have certain side effects, so it is difficult to popularize and apply them. It can also be decocted with 9g of Rhizoma Osmundae, Radix Isatidis, Herba Agastaches and Radix Glycyrrhizae, one dose per day for three days.

Health knowledge lecture 3 students:

In order to improve your awareness of health care and ensure your health, we will give you a health care knowledge propaganda:

Second, pay attention to anti-influenza measures:

Winter is the season when infectious diseases occur frequently in schools. Schools are crowded places, and students are prone to infectious diseases. In order to ensure the physical and mental health of students and the normal teaching order of the school, combined with the actual situation of our school, the following decisions are made, and students are requested to follow them:

5. Go to public places less.

During the flu epidemic, try to go to public places as little as possible. Minimize going to crowded places and reduce the chance of infection. You'd better wear a mask when you come into contact with flu patients.

Step 6 pay attention to the details of life

Increase or decrease clothes according to temperature changes, and improve human immunity through a reasonable and balanced diet. Pay attention to cold and warmth in summer and autumn, and try to reduce the inducement of flu. Although you sweat less in winter, you should drink more water and eat more fruits and vegetables.

Vinegar fumigation has a good effect on preventing influenza. The dosage of vinegar is 5- 10 ml/m3, diluted twice with water, and heated on the stove until the vinegar evaporates, once a day 1 time, for continuous use. The floors of classrooms and dormitories are cleaned by wet method every day, and the floors are disinfected during the epidemic.

9. Drug prevention

At present, it is recognized that amantadine drugs can prevent influenza A, and its mechanism is to inhibit the virus from entering upper respiratory epithelial cells.
