Little known medical knowledge 1. What are the unknown medical secrets
You are all Where did you get your health knowledge? Some healthy lifestyles known within medicine may not necessarily be made public. Take a look at the 20 medical secrets summarized for you below.
1. The medical secret of fruit acid. Fruit acid can help digestion. If you have indigestion, I encourage you to eat a piece of fruit after a meal. But if you have good digestion, eating fruit after a meal may not be helpful.
Because after food enters the stomach, it takes two hours or even longer to digest, and fruits, especially hard fruits, such as apples, pears, etc., will stay in the stomach for a long time, not only It increases the burden on digestion and produces gas, causing abdominal distension. Therefore, it is recommended that you eat fruit 1 to 2 hours after a meal.
2. Medical secrets of fasting physical examination: The physical examination requires a fasting, but it does not require you not to eat from the night before. The results of the physical examination will be inaccurate. My suggestion is to eat a light diet the night before the physical examination, and of course not drink alcohol, including coffee and strong tea. On the morning of the physical examination, do not eat breakfast, drink less water, and do not do physical exercise.
3. Medical secrets of myopia surgery Not everyone is suitable for myopia correction surgery unless you have been wearing myopia glasses or contact lenses continuously and stably for more than a year before surgery. If you take off and wear glasses, be sure to tell your ophthalmologist, and it is best not to undergo corrective surgery for myopia in the near future, otherwise it will affect the doctor's judgment of your corrected vision.
4. Medical secrets of sunglasses. Wearing sunglasses is very important to protect your eyes from cataracts and other eye diseases, especially between 10 am and 4 pm when the sun is the strongest. when. When it comes to specific choices, it doesn’t mean that the more expensive the lens is or the darker the lens, the better. It should be considered whether the lens is labeled to block 100% of ultraviolet rays.
Don’t just choose good-looking frames. And ignore the quality of the lenses.
5. Medical secrets of natural childbirth. Don’t worry that natural childbirth will cause the vagina to become loose. There is no basis for being out of shape.
*** It is almost the most elastic muscle in your body. It can recover quickly even if it bleeds slightly due to childbirth. As for worries about your body shape, as long as you do not over-supplement your nutrition during pregnancy, not only will your body shape not be lost, but you will be able to reshape your body after delivery.
More importantly, natural childbirth can prevent the onset of many gynecological diseases in women. Doctors encourage natural childbirth, and cesarean section is only an auxiliary means. 6. The medical secrets of cesarean section. As an obstetrician, I understand the disadvantages of anatomical cesarean section better than anyone else.
Compared with the painful contractions of natural childbirth, the wound after cesarean section is more painful, and you can’t get out of bed for 24 hours after cesarean section, and you can’t have milk until 3 days later, which will be very difficult for both mother and baby. Suffer. Every woman’s experience of uterine contraction pain is different, and some may even feel it is not very painful. What is shown in movies and TV dramas is an artistic exaggeration.
Confidence is the most important thing about natural childbirth. The moment the child is born, all pain and discomfort will be replaced by a huge sense of happiness. 7. Medical secrets of viral infection: A large number of patients infected by the virus are actually contaminated by "second-hand houses".
It is understood that less than 10% of homeowners disinfect their houses when renting them out, and mites, cold viruses, hepatitis B viruses, measles viruses, molds, etc. can all be exposed at room temperature for a long time. Survival inside the house. If you are moving in the winter, you need to be even more careful because these viruses and bacteria will survive longer at low temperatures.
Therefore, before moving into a newly rented house, it is very important to pre-disinfect the house. Walls, under the bed, sinks, and toilets should not be missed. In particular, professionals should be hired to clean and disinfect the air conditioner. 8. Medical secrets of hair dyeing. Although there is a direct correlation between hair dyeing and blood diseases, there is no medical statistical data to confirm it. However, according to my experience, if you dye your hair more than 4 times a year, you may experience dizziness, migraine, and lower platelets. It is much larger than that of people who do not dye their hair, and the number of white blood cells in some people will be significantly reduced, which means that their immunity is reduced.
9. The medical secret of drinking water. Drinking more water is not the better. Theoretically, drinking more water can help the kidneys detoxify and reduce the burden on the kidneys, but you must know that the human body is a strict balance. System, adult kidneys can only drain 800 to 1000 ml of water per hour. If you drink more than 1000 ml of water in an hour, it will lead to hyponatremia and affect kidney health. Therefore, do not drink more than 100 ml of water each time and do not drink more than 1000 ml of water per hour.
10. Digital syndrome. Long-term computer use, frequent texting, and years of driving. Such living habits will cause nerves in your wrist to be compressed and damaged. If you experience joint pain in your wrist, elbow, or shoulder, it's possible that your nerves have been damaged.
If this situation is left unchecked, the pain will become more and more severe as the age increases. Therefore, don’t be careless and go to the hospital for microsurgery diagnosis and treatment in time.
11. The medical secrets of acupuncture Acupuncture for weight loss is not effective for everyone. Because the principle of acupuncture for weight loss is to target relevant acupoints to reduce appetite, thereby achieving the purpose of weight loss.
Therefore, if you usually eat a lot and are simply overweight, then choosing acupuncture to lose weight will have good results. But if you don't eat much at ordinary times and it's due to endocrine disorders that cause obesity, it's best to go to an endocrinologist for a check-up.
12. The secret of physical therapy Physical therapy is becoming more and more popular now, and many muscle injuries caused by sports choose this non-drug method to treat. In China, many undergraduate and graduate students are engaged in this work.
But if I go to see a doctor, I will still choose the old head nurse who is the foreman in the clinic. Although they are not highly educated, they have rich experience, and physical therapy is an empirical discipline. Some people Some people need this kind of treatment, but they cannot use this method to **. It makes no sense, and knowledge cannot explain it at all. Although the postgraduate degree is high, the clinical time is not long enough, and sometimes it is difficult to judge, but the experienced nurse can quickly judge and make the correct treatment based on experience.
13. Medical secrets of B-ultrasound In foreign countries, B-ultrasound doctors are given special allowances because rays can cause more or less damage to the body. The "hidden rule" for pregnant mothers in China is usually to have a B-ultrasound examination every month after 3 months.
However, during the baby's neurological development period, any small impact may cause harm to his future. So my suggestion is that pregnant women should not have more than 3 B-ultrasound examinations, and.

4. Common medical knowledge
Nasal rubbing and nasal washing are good for health. Chinese medicine believes that the lungs open to the nose.
This means that the ventilation and olfactory functions of the nose mainly rely on the function of lung qi. When lung qi is harmonious and breathing is facilitated, the nose's sense of smell can be sensitive. When the cold wind blows in winter, many people sneeze constantly, have runny noses, and develop cold symptoms such as sore throat and cough.
Nose rubbing To prevent sneezing, nasal itching and other symptoms of colds, you can rub your nose regularly. The method of rubbing the nose is: rub the outer sides of the thumbs of both hands against each other. When there is a feeling of heat, rub the outer sides of the thumbs up and down along the bridge of the nose and both sides of the nose about 30 times.
Next, massage the Yingxiang points on both sides of the nose 15 to 20 times (Yingxiang point is 0.5 cm beside the outer edge of the nose). Techniques range from light to heavy, being careful not to damage the skin.
It can be done once before getting up in the morning, once before going to bed in the evening, and can also be done at other free times. This method can clear the meridians, enhance local qi and blood circulation, and greatly enhance the cold resistance of the nose. It can effectively prevent colds and nasal diseases, and can also treat colds and nasal congestion.
Nasal Wash We breathe through our nose every day and inhale a large amount of dust, bacteria, sulfur dioxide and other waste gases and viruses in the air. As the first point of contact between the human body and air, the nose is always invaded by dirty air.
Although the nasal mucosa has a certain filtering and cleaning function, if you wash your nose frequently, you can remove dry scab in the nasal cavity in time, which will make the nasal cavity better perform its filtering and cleaning functions. The method of nasal washing is: fill the palm with warm water or warm salt water, lower your head and gently inhale it through the nose, then blow it out through the nose, repeat several times.
You can also hang the warm saline bottle high, connect it to the infusion tube, extend the mouth of the tube into the nasal cavity 2 to 3 cm, and blow it out while rinsing. Cold water nasal washing should be encouraged all year round, especially when washing your face in the morning. Washing the nose with cold water several times can improve the blood circulation of the nasal mucosa, enhance the nose's ability to adapt to weather changes, and prevent respiratory diseases.
In addition, bad habits such as picking your nose, plucking or cutting nose hair should also be corrected, because damaging the nose hair and nasal mucosa will not only affect the filtration function of the nose, cause bacterial infection in the nasal cavity, but also may cause brain damage. Diseases of the inner and ear.
Foods that children should not eat: Bubble gum: The plasticizer in bubble gum contains trace amounts of toxins. Regular consumption of bubble gum can have an impact on children's physical development and health.
Popcorn: Children are very interested in popcorn, especially children in rural areas. However, popcorn contains a lot of lead. When lead enters a child's body, it will damage the child's nervous system and hematopoietic function, causing mental retardation and anemia.
Jelly: Jelly is made from flavors, thickeners, colorants and sweeteners. Eating more and more jelly affects not only children's growth and development, but also their IQ.
What is even more dangerous is that if children inhale too quickly and accidentally enter the trachea, foreign bodies in the bronchus may cause choking or coughing, or they may block the bronchus and cause suffocation or death. Cold drinks: Cold drinks are also processed from the above substances. In addition to affecting IQ, children who often eat cold drinks will reduce their local resistance and disease resistance. Children often catch colds. In addition, frequent cold drinks will affect their digestive juices. secretion, causing the child to have loss of appetite and indigestion.
Chocolate: This is because chocolate contains substances similar to caffeine that excite the nerves. It can make children extremely excited, accelerate their heart rate, make it difficult to fall asleep, and even cry and be hyperactive. Mutton kebabs: After mutton kebabs are grilled and smoked, a strong carcinogen, benzopyrene, will be produced, which can cause stunted growth and low immune function in children. Regular consumption may also induce cancer.
Pickles: Various pickles, such as pickled meat, pickled eggs, pickled fish, pickled vegetables, etc., contain dimethyl nitrate. When these substances enter the human body, they will be converted into dimethyl nitrite. Carcinogens such as amines and propionaldehyde, which children eat more and often, not only affect their digestive function, but may also induce cancer. Instant noodles: Instant noodles are delicious and very popular among children. However, they contain preservatives and food colorings, which hinder children's growth and development, and can affect memory and attention.
Salt: Children’s diet should be light and not too salty. Excessive salt consumption in children can weaken the body's resistance and make them prone to colds.
This is because salt (sodium chloride) can inhibit the activity of respiratory bacteria and hinder the disease resistance of bacteria. At the same time, saliva secretion is reduced, and lysozyme in the mouth is correspondingly reduced, allowing cold viruses to take advantage of the weakness. Make trouble and cause colds. What is good medicine? People often say, "You can't get good medicine when you go to the hospital."
There are also people who ask doctors to prescribe "good medicine" regardless of the specific conditions of their diseases, always thinking that cheap medicines will not cure the disease. So what kind of medicine is considered a good medicine? In fact, good medicine does not lie in being new, expensive, or imported. As long as it is safe, efficient, low-priced, and convenient to take, it is a good medicine.
■It’s not about using too many medicines, but about being accurate. It is necessary to make a clear diagnosis and prescribe the right medicine; the medicine should not be used indiscriminately and indiscriminately, but should be targeted.
■Some new drugs sold on the market are actually the ingredients of some old drugs, but they have been given new names, packaging, dosage forms, and "foreign names". ■The effectiveness of treating a disease mainly depends on whether the medication is symptomatic and whether the treatment plan and medication use are reasonable.
Effectiveness does not depend on whether expensive, new or imported drugs are used. Whether it is a domestically produced drug or an imported drug, as long as it is a qualified product that meets drug quality standards, it is effective.
■More and more people are taking over-the-counter medicines nowadays, and over-the-counter medicines are not absolutely harmless. When people buy and use medicines on their own, they must be aware of safety, strengthen the study of medical science knowledge, read the drug instructions carefully, take medicines according to the symptoms, follow the contraindications, and try to avoid blind combination of medicines.

9. Hygiene common sense for middle school students
1. Wash your hands before eating and after going to the toilet: Hands are the "diplomatic organs" of the human body, and they take the lead in all people's "foreign affairs activities". It has to be done by hand. Scientists have conducted a survey and found that an unwashed hand contains at least 40,000 to 400,000 bacteria.
The cracks between fingernails are a good place for bacteria to hide. There can be as many as 3.8 billion bacteria hidden in a crack between nails. Influenza viruses can survive on moist, warm hands for 7 days.
Therefore, hands are very dirty. Moreover, when traveling, visiting and studying, or performing tasks, if your hands often come into contact with some items, your hands will get dirty.
Especially patients with infectious diseases and some seemingly healthy people who actually carry viruses in their bodies often spread pathogenic microorganisms to various supplies and utensils. When healthy people’s hands come into contact, pathogenic microorganisms are released. On your hands. Washing your hands can remove bacteria and insect eggs adhering to your hands. Washing your hands with running water can remove 80% of the bacteria on your hands. If you wash your hands with soap and then rinse them with running water, your hands can be washed away. Up to 99% of bacteria. 2. Don’t spit anywhere or shake your nose: Everyone can spit, but not everyone has a good way of spitting.
Some so-called "hygienic" people spit phlegm on the ground and wipe it with their shoes, thinking that it is clean if they can't see the phlegm. Little do we know that sputum contains millions of bacteria, viruses, fungi, etc.
People suffering from respiratory diseases, such as tuberculosis, influenza, meningitis, etc., have more bacteria and viruses in their sputum, as was the case with SARS. Millions of Mycobacterium tuberculosis can be found in a mouthful of sputum from a tuberculosis patient.
If you spit the phlegm on the ground, when the phlegm dries, the bacteria will fly into the air with the dust. Healthy people may get respiratory diseases if they inhale such dust. Therefore, everyone should develop a good habit of not spitting everywhere.
If there is phlegm, spit it into the spittoon, and the spittoon should be cleaned regularly every day. In places where there is no spittoon, the spit should be wrapped in waste paper and then thrown into a wastebasket or trash can to prevent spitting and maintain hygiene in public places.
3. Do not cough or sneeze in front of others: Without paying attention to the occasion, sneezing in front of others or food is an unhygienic and bad behavior. According to research, a cough can eject 20,000 very small droplets, and a sneeze can eject nearly 1 million droplets.
Moreover, the droplets are ejected very quickly. They can fly 4.6 meters in less than 1 second, and can reach 9 meters with a favorable wind. The nasal cavity and throat are one of the places where bacteria and viruses live most densely, and the sprayed droplets contain a large number of bacteria and viruses.
A sneeze can exhale up to 85 million germs. These tiny droplets can float and swim in the air for a long time. They can float for 30-60 minutes in a windless room and have a long floating time. can last up to 30 hours. Among the notifiable infectious diseases in my country, 15 are airborne (such as chickenpox, mumps, mycoplasma pneumonia, etc.).
Therefore, for everyone’s health, you should pay attention to courtesy and hygiene when coughing and sneezing. 4. Don’t smoke: Smoking is harmful and has no benefits, which has been recognized by the scientific community around the world.
Tobacco smoke contains more than 3,000 harmful substances. Among them, there are mainly nicotine (nicotine), tobacco tar, fluoric acid, acrylic acid and carbon monoxide.
Nicotine is a toxic substance. Cigarette tar contains nitrosamines, phenols, arsenic and radioactive isotopes. These are carcinogens or carcinogens, especially benzopyrene, which is recognized as a strong Carcinogens. According to statistics, people who smoke 40 cigarettes a day have a 70 times higher incidence of lung cancer than non-smokers.
In addition, smoking is also closely related to laryngeal cancer, esophageal cancer, gastric cancer, etc. Smoking can promote the development of systemic arteriosclerosis and hypertension, so smokers have higher morbidity and mortality from cardiovascular and cerebrovascular diseases than non-smokers.
In addition, smokers are prone to tracheitis, bronchitis, emphysema, etc. Some people say that smoking can refresh you and improve work efficiency. This is a misunderstanding.
Modern medical research believes that for people who smoke heavily for a long time, the excitation and inhibition processes in the cerebral cortex are out of balance, and instead they suffer from memory loss, distraction, and reduced work efficiency. Many smoking-related diseases have a long incubation period and are not as rapid as the reactions to highly toxic substances.
Therefore, in a short period of time, people often cannot see his harm. Sometimes it can take decades from the onset of smoking to death.
This is also the main reason why ordinary people have insufficient awareness of the dangers of smoking.
There are about 200-300 million smokers in our country, accounting for more than 1/5 of the country's population and 1/4 of the 10-1200 million smokers in the world. Not only does it consume a lot of money every year, but it also consumes a lot of money for the country and individuals many years later. An unimaginable amount of money is invested in treating the various diseases caused by smoking.
At present, European and American countries have seen the huge harm of smoking and have used various legal, economic and political means to significantly reduce the smoking rate among the masses. For example, U.S. law clearly stipulates that those who sell cigarettes to teenagers under the age of 18 will be subject to severe fines and even be prosecuted in court.
(Newspapers are also publishing complaints from local people in Europe and the United States that tobacco companies and advertising companies that advertise tobacco have harmed themselves and their families). As our country is still in the process of reform and opening up, some laws are not yet complete, and some departments regard cigarettes as a magic weapon to create huge profits. Young people regard holding a cigarette in their hands or in their mouths as a sign of maturity. Even some women are now joining the ranks of smokers.
A well-known foreign scholar predicts that about 50 million young people under the age of 20 in China will die from smoking in the future. Therefore, many people currently believe that smoking is a public hazard, the plague of the 21st century, and the opium of the new century, which is endangering the Chinese nation.
5. Do not drink excessively: Modern medical research shows that when the alcohol concentration reaches 0.6%, it often leads to death. The damage of drunkenness is systemic, and its consequences are quite serious. A Chinese scholar dissected 47 corpses that died due to drunkenness and found that all the deceased's internal organs were extensively congested, especially the mucosal congestion, edema and bleeding of the stomach and duodenum were more serious, and some gastrointestinal mucosa could undergo necrosis.
Many scholars have pointed out that drinking a large amount of alcohol at one time can cause the cerebral cortex to be in a highly inhibited state and inhibit the respiratory and circulatory centers, leading to respiratory arrest. This is a common cause of death for drunk people. 6. Do not drink unclean water, wash or peel raw fruits and vegetables, do not urinate or litter, etc.
