The speech is mainly to express opinions and opinions, and it is prepared in advance for the speech. In daily life and work, there are more and more occasions where speeches can be used. Do you know the format of the speech? The following is a sample of health knowledge lectures I collected for you, which is for reference only and I hope it will help you.

Health is the first wealth of life, and health and longevity are the life goals pursued by human beings. It is worth noting that at present, there are 654.38+600 million patients with hypertension, 40 million patients with diabetes, 654.38+600 million patients with dyslipidemia and more than 200 million overweight and obese people in China, which are the main reasons for the high incidence of cardiovascular and cerebrovascular diseases. Whether a person can live a long and healthy life depends on uncontrollable factors, such as heredity, social environment and medical conditions, accounting for about 25%, 65,438+05%, and controllable factors, such as unhealthy lifestyle, accounting for 60%. So many people died not of diseases, but of unhealthy lifestyles. The key to health lies in everyone's own hands, which requires us to eat reasonably, exercise properly, quit smoking and limit alcohol, have a psychological balance and keep in good health scientifically. So as to improve people's quality of life and achieve the purpose of prolonging life, health and longevity.

First, conform to nature and eat reasonably.

Everyone's eating habits are different, so let nature take its course, eat all kinds of meat and vegetables, and advocate diversified daily diet and comprehensive and balanced nutrition. Limit salt intake and increase vegetables, fruits, dairy products and bean products. People who eat more fruits and vegetables every day have a lower relative risk of cardiovascular and cerebrovascular diseases, while excessive intake of fat and cholesterol will accelerate arteriosclerosis and easily lead to cardiovascular and cerebrovascular diseases. Excessive salt will raise blood pressure and promote the formation of arteriosclerosis. Huangdi Neijing said: "Five grains are for nourishment, five fruits are for help, five livestock are for benefit, and five vegetables are for supplement." Whole grains are very important, five fruits help digestion, five livestock benefit meat, and five vegetables are the supplements of various vegetables. This is the experience of diet structure summarized by our ancestors. Everyone can adjust according to their different physique. With the growth of age, we should pay more attention to the diet structure after middle age, which is delicious and full.

Second, proper exercise, combination of static and dynamic, and weight control.

Proper physical activity can improve heart function, increase cerebral blood flow, improve microcirculation, reduce elevated blood pressure, control blood sugar level, blood lipid and lose weight, thus playing a role in preventing and treating cardiovascular and cerebrovascular diseases. It is recommended to do aerobic exercise at least 3-4 times a week, and the duration of each activity is not less than 30 minutes. Aerobic exercises such as brisk walking, jogging, Tai Ji Chuan, swimming and aerobics should be selected according to the specific situation of each person, and the exercise time is best after the sun comes out in the morning or in the afternoon, because the early morning period is a period of high incidence of cardiovascular diseases, and middle-aged and elderly people, especially those with cardiovascular diseases, should be cautious in doing morning exercises. Exercise is important, but once the following situations occur, such as severe dyspnea, chest tightness, obvious palpitation, dizziness, pale face, etc., you should stop exercising immediately and seek medical attention as soon as possible if necessary. The ideal weight is about height (cm) minus 105, and the weight fluctuation range is within plus or minus 10% of the ideal weight.

Life lies in exercise, longevity lies in tranquility, and tranquility refers to peace of mind, inner peace, and maintaining a harmonious balance in the internal environment. Through quietness, the energy consumption of human life activities can be reduced, so that life can enter the best running state, and the combination of static and dynamic can achieve the purpose of prolonging life, health and longevity.

Third, quit smoking and limit alcohol, pay attention to drinking and drug reaction.

Smoking is a risk factor for cardiovascular and cerebrovascular diseases. Smoking can damage vascular endothelial cells, cause vasospasm, accelerate arteriosclerosis, promote platelet aggregation, and promote thrombosis and arrhythmia. Therefore, it is necessary to encourage smokers to quit smoking. Long-term heavy drinking leads to an increase in the incidence of cardiovascular and cerebrovascular diseases, including hypertension, hypercoagulability, arrhythmia and decreased cerebral blood flow. Therefore, it is suggested that drinking must be moderate. Drink no more than 50 ml of white wine (that is, one or two, the ethanol content is less than 30 g), no more than 640 ml of beer, no more than 200 ml of wine, and half of women.

What needs to be reminded here is that drinking alcohol should be prohibited during injection or oral administration of cephalosporins, antihypertensive drugs, hypoglycemic drugs, and nitrate drugs for cardiovascular treatment (such as nitroglycerin, isosorbide dinitrate, Xinkang, etc.). ), metronidazole, chloramphenicol, furazolidone and other drugs. Avoid alcohol affecting the metabolism of drugs in the liver, so as to avoid life-threatening adverse reactions such as nausea and vomiting, increased heart rate, facial flushing and even anaphylactic shock.

Fourth, keep a psychological balance and maintain a good attitude.

It is a healthy science and an art of life to consciously keep a happy mind forever. Who's advice on mental health is: "know yourself and accept yourself;" Accept others and be kind to others; Face up to reality and accept it; Love life, enjoy life. "Everyone has emotions, worries, sadness and fears, but we must remember not to overdo it, which will hurt our health. Once people's mentality is out of balance, it will inevitably lead to the dysfunction of neurohumoral system and the decline of immune function, which will bring opportunities for the occurrence of diseases and even cause sudden death. Maintaining a good psychological balance and a good attitude is the most important thing for health and longevity.

Introduce several kinds of health massage for your reference.

(1) Burn your eyes and rub your face: Rub your eyes with both hands for three or five times, then gently push the roots of your two thumbs from the corner of your eyes to the back of your ear through the hair in your temple and rub your ears for three or five times.

Knead knuckles: Knead knuckles of left hand with thumb and middle finger of right hand, press knuckles 18-36 times from front, back and inside in the order of thumb, index finger, middle finger, ring finger and little finger, and then change hands. Clap your hands: stand or sit, put your hands together on your chest, then clap your palms in front of your abdomen several times, and then put your hands together.

(3) Abdominal massage: scientifically rub the abdomen, enhance the function of gastrointestinal tract, rejuvenate the body and strengthen the body. Rubbing the abdomen should be done before going to bed and when getting up in the morning. First, you can empty your urine and stand or lie on your back. You must concentrate and stay in the abdomen (four horizontal fingers below the navel). Put your left hand on the back of your right hand and rub the whole abdomen clockwise 100 times and counterclockwise 100 times from the inside out. Then massage with your fingers at Qihai point (2 fingers below navel) and Guanyuan point (4 fingers below navel) for 99 times.

(4) Leg and sole massage: Focus on Zusanli point and Yongquan point. Massage Zusanli point and Yongquan point can regulate the spleen and stomach, replenish the middle energizer, dredge the meridians, eliminate evil spirits and strengthen the body. Zusanli point, also known as Healthy Longevity Point, is located on the anterolateral side of the calf and four fingers below the knee. Yongquan point has been said since ancient times that rubbing the soles of your feet one hundred times before going to bed can prolong your life. This point is located at the bottom of the foot, the depression in the front of the foot when curled up.

There are many ways to keep in good health, but they vary from person to person and cannot be copied in life. Finally, I need to remind everyone that if you are sick, you should go to a regular hospital in time to avoid unnecessary harm.

About health knowledge lecture model essay 2 students:

In order to improve your awareness of health care and ensure your health, we hereby publicize your health care knowledge:

First, 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 quality problem, it cannot be investigated.

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.

Second, pay attention to anti-influenza measures:

Winter is the season of 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:

1, strengthen morning check-up and seek medical attention 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.

2. 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.

Step 3 wash your hands often

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.

Step 4 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.

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. 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.

7, 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.

8, disinfection and terminal disinfection at any time

Disinfect the classes and dormitories of sick students at any time/at the end, and disinfect the classrooms and dormitories 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 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. 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.
