2. Health tips

Cut the dried tangerine peel into shreds, add a little rock sugar, and then simmer with low fire to make a thick orange juice, which can treat cough! It is best to eat after three meals. Scrubbing wooden and bamboo tables and chairs with residual tea leaves can make them smoother.

Dry the remaining tea leaves and spread them in a damp place to remove water; After the tea leaves are dried, they can also be put into pillowcases as pillow cores, which are very soft. Water is an indispensable and important substance for human survival. People can eat nothing for a day, but they can't drink water for a day. However, not all water can be drunk. The following five kinds of water will form toxic and harmful substances such as nitrite to a certain extent, which will cause certain harm to human body, so people should pay attention to it.

You can't drink seven kinds of water. First, aged water: commonly known as "stagnant water", that is, water that cannot be stored for a long time. Drinking this kind of water often will obviously slow down cell metabolism for minors and affect the growth and development of the body; Middle-aged and elderly people will accelerate aging; The incidence of esophageal cancer and gastric cancer is increasing in many places. According to the research of medical scientists, this may be related to drinking aged water for a long time.

Relevant data show that the toxic substances in aging water also increase with the increase of water storage time. 2. Thousands of boiling water: Thousands of boiling water refers to the water that has been boiled on the stove for a night or a long time, and the water that has been repeatedly boiled in the electric water heater.

Because this kind of water takes a long time to boil, the content of heavy metals such as calcium and magnesium and nonvolatile substances such as nitrite in the water is high. Drinking this water for a long time will interfere with people's gastrointestinal function and cause temporary diarrhea and bloating; Toxic nitrite can also cause hypoxia in the body, which can lead to coma, convulsion and even death in severe cases.

Third, boiler water: boiler water is leftover boiler water such as buns, especially boiler water that has been reused many times, and the nitrite concentration is very high. Drinking this water often, or cooking porridge with this water, will cause nitrite poisoning; Scale often enters the human body with water, and it can also cause digestive, neurological, urinary and hematopoietic diseases, and even cause premature aging.

Fourth, the water that can't be boiled: the tap water that people drink is chlorinated and sterilized. 13 A variety of harmful substances can be separated from chlorine-treated water, among which halogenated hydrocarbons and chloroform also have carcinogenic and teratogenic effects.

When the water temperature reaches 90℃, the content of halogenated hydrocarbons increases from 53 micrograms per kilogram to 177 micrograms, which is twice as high as the national sanitary standard for drinking water. Experts point out that drinking raw water increases the possibility of bladder cancer and rectal cancer by 2 1%-38%.

When the water temperature reaches 100℃, these two harmful substances will be greatly reduced with the evaporation of steam. If boiling lasts for 3 minutes, it is safe to drink. 5. Boil water again: Some people are used to boiling the remaining warm water in thermos bottles before drinking, in order to save water, coal (gas) and time.

But this "saving" is not enough. Because water burns and evaporates, nitrite will rise. If you drink this water regularly, nitrite will accumulate in the body and cause poisoning.

How to prevent carsickness 1 The carsick person takes Shangshi Zhitong Ointment 1 tablet one hour before taking the bus and sticks it on the liver and navel (called Shenque point). If you ride for more than one day, change to another post the next day.

Can effectively prevent carsickness. 2. Fasten your seat belt before getting on the bus to prevent internal organs from swimming excessively in the body, which helps to prevent carsickness.

3. There is a piece of ginger in your mouth. People who love carsickness should take a piece of fresh ginger with them and eat 2 pieces of fresh ginger before getting on the bus, which can greatly reduce carsickness.

Don't eat acute gastritis when you are sick: fried food, wine, pepper and glutinous rice. Cold: banana, orange, Lu Xun juice, ice, mutton, ginger duck, alcohol and tobacco. Chronic gastritis: cold food, sour fermented food and sweets. Cough: ice cream, orange, fried, roasted, spicy, peanut, wine and dessert: peanut, sweet potato and egg fermented. Heart disease: overeating, high cholesterol, salty food, rheumatoid arthritis: beer, bananas, meat, shelter from cold and rain, diabetes: sweet, wine, greasy, fried, high-calorie food, traumatic injury: pig's head, flesh and blood, vinegar, peanuts, sweets, bananas, beer, hypertension: salty food, egg yolk, animal viscera, cheese. Guava pregnancy: wine, tobacco, coffee traumatic periostitis: banana, bamboo shoots, wine, sauerkraut, pepper hypotension: celery, should go to bed early and exercise more, hemorrhoids and bloody stool: tobacco, wine, pepper, fried food, kidney disease: beer, soda, salted fish, dried bamboo shoots, pickles allergic constitution: (measles, eczema, asthma, allergic rhinitis) seafood. The content of physical education class in primary schools must be conducive to promoting the all-round development of students' bodies and effectively exercising and strengthening their physique.

First, choose the right venue. At present, the general school sports venues are mostly cement, such as basketball courts and volleyball courts. In fact, the playground paved with cement asphalt is hard and elastic. Jumping in this site run for a long time is not only easy to cause trauma, but also causes chronic damage to the human body.

Therefore, qualified schools should try to set up plastic venues. This kind of venue can protect students from injury, and schools without conditions try to keep soil venues and battlefields.

Second, it is very important to ensure the safety of equipment. The choice of equipment is very important for the safety of students. Schools should strive to gradually complete the equipment according to the requirements of the new curriculum. If the temporary conditions are limited, teachers and students can be mobilized to make their own equipment, but health and safety factors must be considered. It is necessary to ensure that unqualified equipment is not used, and bad equipment cannot be used.

Third, class notes 1. Reasonable selection of exercise load. The characteristics of physical education itself determine that physical exercise is the main feature, outdoor is the main place, and it is dynamic, which increases the difficulty of organizing teaching.

If students use instruments improperly or have too much physiological load, they are prone to injury accidents. 2. Strengthen physical education class's safety awareness.

Physical education class requires students' bodies to participate in activities directly. There are indeed unsafe factors and potential dangers in the activities. However, as long as we attach importance to protection education, organize classes well, teach correctly and scientifically, and strengthen protection measures.

3. Composition: 600 words for impressions of health lectures.

Impression of health lecture

In order to advocate scientific ideas, improve the quality of life, pay attention to employees' health and advocate reasonable nutrition, Tieneng Company invited Professor Yang Jun from China Medical University to give a wonderful lecture on healthy diet for Tieneng Company employees-"Balanced diet and reasonable nutrition".

I am honored to attend the lecture in person. In this lecture, we learned a lot of health knowledge beneficial to our health, such as: millet and wheat are cool and can be eaten with hot and dry food. Vegetarian dishes are not good with millet. Mung beans are cold, detoxifying and relieving summer heat, and hurting the kidney. Cold is laxative, and warm is tonic. All kinds of beans, red beans, black beans and other soy products are difficult to digest, diuretic, so that qi and blood can descend, and people with head and face ischemia can not eat red beans and black beans. As long as you feel bloated after eating, it means you have a cold. Tips for bloating: eat two slices of ginger to neutralize the wind and cold. Fungi, which grow in wet areas, have the heaviest cold and humidity. Eat less fungi, and put more peppers, onions, ginger and garlic when eating. Fruit, people who eat fruit every day are in poor health and can only eat fresh fruit. Apples stored for four months have no nutrition at all. Only eat fresh fruits in the season, not fruits in the wrong season. Diet misunderstanding: you can't drink milk on an empty stomach. The milk is cold, don't drink it. She told us that all drinks are not as good as drinking boiled water. Fish: There are too many opportunities for river fish to be polluted. Now it is said that there is a lot of melamine in fish feed, so try to eat marine fish. Eating fish should be combined with meat, and people with many problems eat less fish, which is harmful to obesity and so on, which has benefited me a lot. Anyway, Professor Yang Jun's point of view still makes us feel refreshed. After listening to the summary, I have the urge to try.

Primary school students' basic hygiene knowledge 1, wash their hands before and after meals; 2, do three diligence: diligent bathing, diligent haircut, and diligent dressing; 3, diligently cut nails; 4, pay attention to reading and writing hygiene: the eyes are one foot away from the book, the body is one punch away from the table, and the hand is one inch away from the nib; 5. Wash your hands frequently anytime and anywhere; 6. Pay attention to eye hygiene: don't read in strong light, don't read in a walking car, don't read while lying down, and don't rub your eyes with dirty hands; 7. Do not eat unsanitary food, do not eat unwashed food, and do not drink raw water; 8.

Brush your teeth in the morning and evening and rinse your mouth after meals; 10, insist on proper physical exercise every day, in order to enhance physical fitness and maintain good and abundant energy.

Pupils should pay attention to eye hygiene. Two things should be done (1). There are two things to do: ① The posture of reading and writing should be correct, and "one foot, one punch and one inch" should be maintained, that is, the eyes should be one foot away from the book, the body should punch from the edge of the table, and the fingers should be one inch away from the pen tip; (2) Take a rest after reading and writing for an hour or so, or look far away for a while. (2) Don't: ① Don't read or write in dim light or direct sunlight; ② Don't read while lying down, walking or riding a bike.

How to pay attention to hygiene when watching TV? ① Watch TV for no more than 2 hours at a time. After watching TV 1 hour continuously, get up and exercise for 5- 10 minutes. ② The viewer should be more than 2 meters away from the TV screen; ③ The height of the TV set should be consistent with the eye height of the viewer when sitting; ④ It is best to turn on 3-8 watts of small lights indoors to reduce the sharp contrast between the screen and the surrounding darkness, which is conducive to avoiding eye fatigue.

How to protect teeth? 1. The most important thing to protect your teeth is to brush your teeth and rinse your mouth correctly. Brush at least twice a day, preferably after each meal.

Brushing teeth can remove dental plaque attached to teeth, because bacteria in dental plaque come into contact with food, which will produce acidic substances and lead to tooth decay. Brush your teeth unconditionally. At least rinse your mouth immediately after eating or eating acidic substances.

2. Pay attention to your diet. Food should be diversified, but eat less foods rich in sugar (especially monosaccharides).

Because these foods will produce acid in your mouth, the acid will stay in your mouth for a long time and will damage your teeth. Hard lollipops are especially harmful to children.

Eating sugary snacks can also cause tooth decay, because most people don't brush their teeth after eating snacks. Starch snacks, such as potato chips, stick to your teeth.

It is best to floss your teeth once a day. Flossing can remove food and dental plaque left between teeth. If dental plaque remains between teeth, it will form tartar and must be removed by the dentist.

See a dentist every six months. It is very important to have regular checkups and professional tooth cleaning.

If your teeth or mouth are sore or your gums are swollen and bleeding, you should also see a dentist. Usually, we should pay more attention to strengthening exercise, getting rid of bad living habits, eating a balanced and reasonable diet, and combining work and rest.

In addition, if there is a problem, you should go to the hospital to see a doctor. Common brushing methods ① Vertical brushing method: This brushing method has a good effect on gums and can effectively clean the gaps between teeth. It is a recommended brushing method.

During the operation, the bristles were placed on the gums at an angle of 45 degrees, and then rotated to the crown, and each part was repeated 8- 10 times. When brushing the occlusal surface of teeth, put the brush flat on the surface of teeth and pull it back and forth to remove the residue in the pit and fissure.

② Bass brushing method: When brushing the lip and tongue surface of teeth, the bristle head and the tooth surface point to the gum direction at 45 degrees, and the bristles enter the gap between teeth and vibrate back and forth for a short distance. When brushing the occlusal surface, put the bristles flat on the tooth surface and vibrate back and forth for a short distance to clean the pit and fissure. This brushing method has strong cleaning power and can effectively remove the plaque in the neck and gingival sulcus. Bass brush is a short-distance horizontal brush method. Although it is a horizontal brush method, it is almost a kind of vibration because of the short distance, and it is not a great pull and damage to the tooth neck by the common horizontal brush method.

If the vertical brush method is combined with the bass brush method, the effect will be better. ③ Physiological brushing method: the tip of toothbrush hair touches the tooth surface, and then brush slightly in the direction of gum. This method can promote blood circulation and improve the health of periodontal tissue, and is suitable for children with normal periodontal tissue.

It is generally recommended to brush your teeth once in the morning and evening and rinse your mouth after each meal. Brushing time is generally not less than 2-3 minutes. Twelve principles of primary school students' diet 1, pay attention to nutritional balance.

Eat all kinds of food, such as fruits, vegetables, fish, eggs, milk, etc. In the daily diet. Don't be partial to food. 2. Eat more soy products. Beans are rich in high-quality protein, with high nutritional value, low price and easy digestion.

3. Pay attention to the processing method of food. When processing food, master the temperature and methods to minimize the loss of vitamins.

4. Change the variety of food and increase children's appetite. 5. Have fun.

Concentrate and be happy when eating. Eating happily can improve the digestibility of food. 6. chew slowly. Don't eat too fast, especially young children, chew slowly, because chewing more will help improve the digestibility of food and protect the stomach.

7. Don't eat too much. Eating too much will hurt the stomach and reduce the digestibility.

8. Don't eat medicinal food indiscriminately. For example, fortified foods, health foods and other medicated foods should be seriously considered whether they are really needed.

Otherwise, it is equal to taking medicine without illness, which is not only useless but also harmful to the body. 9, do not eat supplements.

Although traditional tonic is beneficial to the elderly and people with weak constitution, it does more harm than good to students, so it is better not to eat it. 10, eat less sugar.

Because there are a lot of carbohydrates in daily diet that can be converted into sugar, it is necessary to properly control soda, chocolate, dessert and milk candy in children's snacks, and not too much.

1 1. Have a good breakfast. Because the nutrients absorbed by breakfast should account for about 30% of the nutrients absorbed throughout the day.

Only in this way can we ensure good health and digest our needs. Therefore, breakfast should have enough nutrition, and you can make some choices among foods with high nutritional value, such as eggs, milk, pork floss, salted eggs, sesame sauce, honey and so on. 12, timing and quantification.

This can make the food center in the cerebral cortex form skill stereotypes, make the digestion and absorption system become regular activities, and promote the improvement of digestion and absorption rate.

6. What does the lecture on mental health knowledge include?

Healthy lifestyle and behavior 1 Wash your hands frequently, take a bath frequently, and do not use towels and toiletries.

Washing hands in the right way can effectively prevent infection and spread diseases. Everyone should get into the habit of washing their hands frequently, especially before preparing food, after eating and defecating, and after going home.

Wash your hands with clean tap water and soap. Wash your hair frequently, have a haircut, take a bath and change clothes, which can remove metabolites such as sebum and dandruff, dust and bacteria in hair, skin surface and pores in time; At the same time, it can also maintain skin and regulate body temperature, and prevent skin inflammation and tinea.

Towels for washing hair, bathing and wiping hands must be clean, and each person should have a basin of towels. Do not share towels and toiletries with others to prevent the spread of contact infectious diseases such as trachoma and acute epidemic conjunctivitis (commonly known as pink eye). Don't bathe with bath towels with others to prevent skin diseases and sexually transmitted diseases. Brush your teeth every day and rinse your mouth after meals.

Advocate brushing your teeth every morning and evening. If you only brush it once a day, you should choose it before going to bed.

Brush your teeth in the right way, not with a toothbrush. To keep the toothbrush clean, it is best to change the toothbrush every three months.

Rinse your mouth after eating to remove food residues in your mouth and maintain oral hygiene. Cover your nose and mouth when coughing or sneezing, and don't spit everywhere.

Pathogens of common respiratory infectious diseases, such as tuberculosis, influenza, epidemic cerebrospinal meningitis and measles, can enter the air with droplets generated when patients cough, sneeze, speak loudly and spit everywhere and spread to others. So don't spit everywhere, and cover your mouth and nose when coughing or sneezing.

This is also the expression of today's social civilization accomplishment. Do not smoke in public places, and respect the right of non-smokers to avoid passive smoking.

The World Health Organization Framework Convention on Tobacco Control points out that exposure to second-hand smoke (passive smoking) can lead to disease, loss of function or death. Passive smoking has no so-called "safe exposure" level.

In the same building, dividing smoking areas and non-smoking areas to separate smokers from non-smokers, purifying the air or installing ventilation equipment can not eliminate the harm of second-hand smoke to non-smokers. If the smoking area is located in the same building, second-hand smoke will spread to every corner of the whole building through heating, ventilation and air conditioning systems.

Even if the number of smokers is small and the room area is large, the harm of second-hand smoke cannot be eliminated by ventilation technology. Only a completely smoke-free environment can really protect the health of non-smokers.

A total ban on smoking in indoor public places and workplaces is the most effective measure to protect people from the harm of passive smoking, and it is also a respect for the rights of non-smokers. Every smoker, please don't smoke in front of family, friends and colleagues when you are a heavy smoker.

Please smoke outside. Drink less and don't drink too much.

Liquor is basically a pure energy food and contains no other nutrients. Excessive drinking will reduce appetite and food intake, leading to nutritional deficiency, acute and chronic alcoholism, alcoholic fatty liver and so on. In severe cases, alcoholic cirrhosis even occurs.

Excessive drinking will also increase the risk of diseases such as hypertension and stroke, and lead to an increase in traffic accidents and violent incidents, which is harmful to personal health and social stability. Alcoholism should be strictly prohibited.

Try to drink low alcohol. It is recommended that adult men drink no more than 25 grams per day and adult women drink no more than 15 grams per day. Pregnant women, children and teenagers should not drink alcohol.

6 Don't abuse addictive drugs such as sedatives, hypnotics and analgesics. Long-term or improper use of sedative, hypnotic and analgesic drugs will lead to addiction.

Drug addiction will damage health, and in severe cases, it will change people's mood, mood, consciousness and behavior, cause personality changes and various mental disorders, and even lead to acute poisoning and even death. Addictive drugs such as sedatives, hypnotics and analgesics must be taken under the guidance of a doctor and cannot be abused.

7. Refuse drugs. Drugs mentioned in the Criminal Law of People's Republic of China (PRC) include opium, heroin, methamphetamine (ice), morphine, marijuana, cocaine, other * * * drugs and * * * drugs that can make people addicted.

It is easy to take drugs, and some people will become addicted as long as they smoke a cigarette containing drugs. Addicts should give up drugs as soon as possible.

Drugs seriously endanger health, drug abuse harms oneself, family and society. In order to prevent the harm of drugs, we should be strict with ourselves and never try drugs.

8 Use sanitary toilets to manage human and animal feces. A sanitary toilet refers to a toilet with a wall, a roof, a toilet pit, a cesspool, no leakage, sanitation, no maggots, basically no odor, and the feces are treated harmlessly and cleaned in time.

Using sanitary toilets and managing human and animal feces can prevent mosquitoes and flies from breeding and reduce the spread of intestinal infectious diseases and some parasitic diseases. Promote the use of sanitary toilets.

Poultry and livestock should be kept in captivity, and livestock manure should be properly handled. Pay attention to the hygiene and safety of drinking water.

Contaminated drinking water will spread diseases such as intestinal infectious diseases and may also cause poisoning. To protect health, we should pay attention to the safety of drinking water.

To ensure the safety and hygiene of drinking water, we must first protect the drinking water source. Advocate the use of tap water.

The polluted water source must be purified or disinfected before it can be used as drinking water. 10. Open the window frequently for ventilation.

Sunshine and fresh air are indispensable for keeping healthy. Ultraviolet rays in sunlight can kill a variety of pathogenic microorganisms.

Let the sun shine into the room often, which can keep the room dry and reduce the chances of bacteria and mold breeding. Receiving sunlight can improve the body's ability to absorb calcium.

A poorly ventilated house will increase the chances of bacteria and viruses spreading indoors. Open the window frequently, keep the indoor air circulating, avoid breathing dirty and toxic air, prevent respiratory infectious diseases and keep healthy.

1 1. The diet should be mainly cereals, eat more vegetables, fruits and potatoes, and pay attention to the collocation of meat and vegetables. Cereal is the main part of China residents' traditional diet, the best basic food for human beings and the most economical energy.

A cereal-based diet can not only provide enough energy, but also avoid excessive fat intake, which is conducive to preventing cardiovascular and cerebrovascular diseases, diabetes and cancer. The Dietary Guide for China Residents points out that adults should consume 250 ~ 400g of cereal every day.

Vegetables and fruits are important sources of vitamins, minerals, dietary fiber and phytochemicals.
