Health knowledge, many people don't talk about health in life. A healthy body is very important to everyone. Without good health, there is no health. Without a healthy body, people will not make money. Let's learn about health knowledge with me.
Health knowledge 1 1. Talking about health and health preservation
In fact, we should pay attention to hygiene everywhere. On the roadside, in the street, in the alley, in the stalls of those vendors, we often make some food such as oil cakes and stinky tofu. You must never buy them. Who knows what they are made of? They are easy to get sick and even cause diarrhea, dizziness and other symptoms. Washing hands before and after meals is also a hygienic behavior.
Speaking of health, some people may say, "If you eat too much, you will be healthy!" In fact, health does not lie in eating more. You should exercise regularly, drink plenty of water, eat on time every day, go to bed on time and so on, so as to be healthy. I read in the newspaper that eating too many fruits and vegetables and eating more vitamins is good for your health. Hygiene and health are closely related. Bad hygiene habits not only make your body easy to get sick, but sometimes even your precious eyes will be attacked. When you come into contact with money, expired books and other items, never rub your eyes, otherwise the bacteria on your hands will enter your eyes, causing trachoma and reducing your vision. In order to have a healthy body, we should develop good hygiene habits in peacetime. Good hygiene habits are not an abstract concept, but are manifested in bit by bit hygiene.
Little things in life. For example, keep yourself clean and tidy, change clothes frequently, take a bath frequently, and cut your nails frequently; Wash your hands before and after meals; Clean the environment frequently; Take part in physical exercise properly to enhance immunity.
Second, food hygiene.
(1), people should pay attention to the hygienic weather when eating hot pot. People like to eat hot pot, but they should pay attention to the following hygienic habits: 1), food should not be overheated, and overheated food can easily burn oral mucosa, esophagus and gastric mucosa, and induce diseases of esophagus or stomach. 2) Don't leave too much food in the hot pot, so as not to cook the food for too long and lose the flavor and nutrition of the dishes. 3), food must be cooked before eating, so as not to infect parasitic eggs or bacteria.
(2) overeating hurts the body. In daily life, some people like to enjoy large pieces of meat and large glasses of wine until they are full of burps and drunk, but they don't know that the hidden trouble is already in it. Overeating exceeds the normal digestion of the spleen and stomach. First of all, it produces a feeling of fullness and is easy to indigestion; Secondly, when a large number of high-protein foods are ingested for a long time, blood ammonia will increase greatly, exceeding the ability of liver and kidney to process ammonia. Produce ammonia poisoning; More seriously, a large amount of ammonia accumulated in the blood will enter the brain tissue with the blood flow, poisoning the central nervous system, ranging from being groggy and unconscious all day, to sudden death after overeating. A scientific diet is to eat well at breakfast, eat well at noon and eat less at dinner to avoid overeating.
(3), beware of food poisoning refrigerator as a kind of household equipment to refrigerate food, the refrigerator has brought a lot of convenience to people's daily life, but the refrigerator is not a safe. Generally speaking, the temperature of the freezer is-15 ~ 18℃, while the normal greenhouse is only 2 ~ 8℃. Low temperature can inhibit most pathogenic bacteria, but it has little effect on psychrophilic bacteria and psychrophilic bacteria. Some bacteria can grow below zero.
Reproduction. So the refrigerator can't inhibit all bacteria, and the food stored in the refrigerator will go bad.
(4) raw and cooked food and knives should be separated. Raw and cooked food refers to the tools for making, holding and storing raw and cooked food. Such as chopping boards, knives and other appliances should be placed separately and marked clearly. Raw and cooked food should not be stored in the same refrigerator or cupboard. Cooked food is easy to be polluted, causing intestinal diseases and parasitic diseases, which is harmful to the body.
(5) What does a balanced diet mean? Food should be varied and light, with coarse grain flour and rice. Eat less fat and sweets and more vegetables and fruits.
(6) Clean the wok in time to keep healthy. Some people don't clean the wok in time after cooking to save trouble, and then fry the next dish, or mistakenly think that the wok is used every day without cleaning. In fact, it is very harmful to health, especially when processing protein and fatty dishes, it will form a' pot scale' containing carcinogens, and eating a small amount of carcinogens often will leave hidden dangers in the body. Therefore, when cooking, you should clean the wok every time you finish cooking a dish. Don't be afraid of trouble and bury the curse. In addition, cooked oil, which is often used many times, will decompose a large number of strong carcinogens such as heterocyclic amines and polycyclic aromatic hydrocarbons when heated at high temperature. Therefore, cooking oil that has been heated at high temperature for many times should be discarded.
(7) Why do you emphasize that eating vegetables and fruits every day can provide a lot of vitamin C for the body, but vitamin C can't be stored in the body?
Health knowledge 2 1. Health knowledge.
First, health knowledge, one of the most important points is to keep a good sleep. You must choose a good sleeping environment when you sleep. The bedroom had better have no sound and no light. And the quilt should be clean and the thickness should be appropriate. Secondly, to maintain a correct sleeping position, it is best to sleep on the right side, so as not to oppress the heart, maintain good blood circulation and help eliminate fatigue.
Secondly, exercise is very effective in promoting health and enhancing physical resistance. When exercising, there are some precautions. It is best not to do strenuous activities half an hour before meals and one hour after meals. After the exercise, you'd better have a rest before drinking water or eating. Moreover, it is necessary to wipe sweat and put on clothes in time after exercise, which helps to prevent colds.
Third, when going out for leisure and entertainment, we should pay attention to preventing some infectious diseases, especially respiratory diseases. In the winter or spring when the flu is frequent, you should go to public places of entertainment less or even not.
Fourth, you must use boiled water when taking medicine, and you can't use other drinks or tea.
Second, little common sense health knowledge
Healthy living habits require us to choose fresh and safe food in our daily life. When we buy food, we should pay attention to the outer packaging of food to see if there is corruption. Small food, in particular, can not only be attracted by its colorful appearance, but also depends on 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. Besides, we should wash the food thoroughly before eating. Especially the raw vegetables and fruits should be cleaned, and the food to be heated should be heated thoroughly. For example, kidney beans and soybean milk contain saponins and other toxins, which will cause poisoning if they are not heated thoroughly.
In addition, we should pay attention to increasing or decreasing clothes according to the temperature change in life, 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. In the choice of food, we should keep a light diet, because a high-fat, high-protein and high-sugar diet will reduce human immunity, while a salty diet will reduce saliva secretion and lysozyme secretion in the oral cavity, and reduce the secretion of disease-resistant factors such as interferon, which will easily make cold viruses enter the respiratory mucosa and induce colds. In addition, we should always change our toothbrushes, because we use them every day. If there is a virus on it, it is easy to be infected repeatedly, and because the toothbrush is often in a wet state, pathogens are easy to breed, which is extremely unfavorable to our health.
Third, how to maintain personal hygiene.
Keep your hands clean. Bacteria on hands can contaminate food and infect wounds. Remember to wash your hands after touching anything that may carry bacteria, after going to the toilet, after taking care of patients, before touching any food, utensils or drinking water. Keep your nails clean and tidy. Don't put your fingers in your mouth.
Keep your hair clean. Your hair may become a habitat for bacteria or fleas, lice or other parasites. Keeping your hair clean, smooth and neatly trimmed can avoid these dangers.
Keep your clothes clean. Try to keep clothes and bedding clean and tidy, reduce the chance of skin infection and reduce the chance of parasite breeding. When the coat is dirty, it should be cleaned in time, and underwear and socks should be changed every day. If there is water shortage, you should wash it with "air" (shake the clothes a few times and then put them in the air and sunshine for two hours). Sleeping bags should be turned over and shaken for ventilation after each use.
Keep your teeth clean. Clean your mouth and teeth thoroughly with toothbrush and toothpaste at least once a day. If you don't have a toothbrush, you can find a twig about 20 cm long and 1 cm wide and make a "chewing stick". Chew one end of it to separate the fibers from the branches. Then, clean your teeth thoroughly with this chewing stick. Another way is to wrap your fingers with a clean cloth and wipe off the food residue on your teeth. You can also brush your teeth with a little sand, baking soda, salt or soap. You can also floss with thread or fiber to clean your teeth and maintain oral hygiene.
If you have a hole in your tooth, you can temporarily fill it with candles, tobacco, pepper, toothpaste or tooth powder and ginger. Before filling a tooth, rinse your mouth or remove the residue to ensure that the cavity is clean.
Take care of your feet. In order to prevent foot problems, try on shoes before going out. Massage your feet every day and cut your nails flat. Shoes should be padded with insoles, and socks should fit and be dry. Rub foot powder every day to check whether there are blisters on your feet.
Fourth, pay attention to personal hygiene etiquette knowledge.
Pay attention to personal hygiene, get a haircut at the right time, comb your hair regularly, shave, manicure, cut your nose hair short and wash away excessive dandruff. Underwear and outerwear should always be kept clean, especially the collar and cuffs. Leather shoes should be polished with oil and cloth shoes should be scrubbed clean. You should dress up before taking part in foreign activities. In short, keep your appearance clean and beautiful.
Don't blow your nose, pick your nose, pinch dirt, dig your eyes, yawn, manicure, pick your teeth, dig your ears, etc. in front of others. When coughing or sneezing, cover your nose and mouth with a handkerchief and face to one side to avoid making a loud noise.
Don't eat spicy food such as onion, garlic and leek before taking part in the activity. If necessary, you can add a little tea to remove the odor.
Sick comrades should not take part in foreign affairs activities. For example, catching a cold is not a serious illness in our country, but people in western Europe, North America and other regions hate catching a cold. Patients with exposed skin diseases such as face, hands and arms should also avoid external contact, so as not to cause resentment to others. People with bad breath should pay attention to oral hygiene.
The furnishings should be kept clean and tidy, and the living room and room should be ventilated without peculiar smell. Keep it clean. Sofa cover and padding should be washed and changed frequently, and lamps, clothes hangers and glass should be cleaned, especially all kinds of lampshades and their decorations. The floor and carpet should be cleaned and vacuumed regularly, and the floor should be waxed.
Keep the environment clean, do not spit or litter. Be sure to keep carpets and floors clean. When smoking, put the ash into the ashtray. When eating food, put bones, thorns, toothpicks, oral paper and other things on the plate or table, and don't throw them on the ground. Personal unclean items should be thrown into trash cans or put into handkerchiefs or pockets. Spitting should be put in mouth paper, handkerchief and pocket. Keep tables, chairs and sofas clean, and don't pedal. When entering the ground clean room, you should rub the soles of your shoes at the door before entering. Rain gear should be placed outside the door or in the front hall on rainy and snowy days. Do not bring rain, snow and mud indoors. Care should also be taken not to dirty the owner's utensils, furniture, doors and windows, glass, curtains, walls, etc.
