Protect teeth

Teeth are important organs for human survival, the main component of chewing organs, and also closely related to language, appearance and health. Besides brushing your teeth every morning and evening and gargling after meals, there are also some effective self-care measures to protect your teeth.

Second, knock your teeth often.

Since ancient times, people who are good at keeping in good health have emphasized that "teeth should be knocked often." Clearly, the diet is not advanced, and the teeth and gums are not filled. Tapping the teeth gently can promote the smooth blood vessels and protect the teeth. "It's obvious that thirty-six pieces have been smashed, but the old teeth won't fall out." The method is to "slightly close your lips, first knock your teeth 50 times, then knock your teeth 50 times, and then knock your wrong teeth 50 times, once a day in the morning and evening.

Third, chew correctly.

The correct way to chew is to use teeth alternately on both sides or both sides.

Fourth, correct bad habits.

Some infants and young children have the habit of sucking their thumbs, licking their teeth, grinding their teeth, breathing with their mouths open and biting their lips, which leads to malocclusion. Correcting bad habits is beneficial to dental care, and teeth should be corrected as soon as possible.

Nineteen bad habits 1. Get up first and cover the human body itself-this is also a source of pollution.

In a night's sleep, human skin will emit a lot of water vapor, making the quilt moist to varying degrees. There are 145 chemicals excreted by human breath and pores distributed all over the body, and 15 1 chemicals evaporated by sweat.

The quilt absorbs or absorbs moisture and gas. If it is not allowed to be emitted, it will overlap, which will easily make the quilt damp and be polluted by chemicals. People who don't eat breakfast will feel tired and dizzy if they eat irregularly. Over time, it will cause malnutrition, anemia, decreased resistance, pancreas and gallstones.

3. Loosening the belt after meals can reduce the intra-abdominal pressure, increase the activity of digestive organs and the load of ligaments, thus promoting the increase of intestinal peristalsis, prone to intestinal volvulus, abdominal distension, abdominal pain, vomiting, and prone to diseases such as gastroptosis. Sleeping after a meal will make the blood in the brain flow to the stomach. Because blood pressure decreases, the oxygen supply to the brain will also decrease, leading to extreme fatigue after meals, which is easy to cause heartburn, indigestion and obesity.

If the blood supply is insufficient, you will fall asleep after meals. This motionless state can easily lead to a stroke. 5. Eating too much can easily lead to memory loss, slow thinking, inattention and weakened stress ability.

Often over-satiated, especially over-satiated dinner, due to excessive intake of calories, will make the body fat excess, blood lipids increase, leading to cerebral atherosclerosis. It will also cause a substance called "fibroblast growth factor" to grow tens of thousands of times in the brain, which is a protein that promotes arteriosclerosis.

The result of cerebral arteriosclerosis will lead to hypoxia and lack of nutrition in the brain, thus affecting the metabolism of brain cells. Often full, it can also induce gallstones, cholecystitis, diabetes and other diseases, which will make people aging before they get old and shorten their life span.

6. More and more evidences show that the longer the hobby of eating sugar on an empty stomach, the more serious the damage to protein absorption. Because protein is the foundation of life activities, eating sugar on an empty stomach for a long time will affect all kinds of normal functions of the human body, making the human body weak and shortening its life span.

7. Eating salty food sodium stays in the human body, which is easy to form or aggravate high blood pressure and heart disease. 8. Beards have the ability to absorb harmful substances.

When people inhale, harmful substances adsorbed on their beards may be inhaled into the respiratory tract. According to the quantitative analysis of the air composition inhaled by bearded people, it is found that the inhaled air contains dozens of harmful substances, including carcinogens such as phenol, toluene, acetone and isoprene, and the air pollution index inhaled by bearded people is 4.2 times that of ordinary air.

If you have a beard on your chin and a moustache, the pollution index can be as high as 7.2 times. Coupled with smoking and other factors, the pollution index will be as high as 50 times that of ordinary air.

9. Crossing your legs and crossing your legs will make the blood flow in your legs poor and affect your health. If you are a patient with venous tumor, arthritis, neuralgia and venous thrombosis, crossing your legs will make your condition worse.

Especially people with long legs or pregnant women, it is easy to get venous thrombosis. 10. Squinting, rubbing your eyes and squinting, crow's feet are easy to appear in the corner of your eyes.

Habitual squinting can also cause eye muscle fatigue, dizziness and headache. When rubbing your eyes, germs can infect your eyes from your hands, leading to inflammation, broken eyelashes or falling off.

1 1. Forced urination may cause acute cystitis, characterized by frequent urination, dysuria, small abdominal distension and pain. A research report released by American scientists pointed out that people who have the habit of holding their urine are five times more likely to develop bladder cancer than the average person.

When holding urine, the urine stored in the bladder cannot be discharged in time, resulting in artificial urinary retention. If you hold your urine regularly, your sphincter and detrusor will always be in a state of tension; If you hold your urine for too long, the amount of urine in your bladder will continue to increase, and the internal pressure will gradually increase. After a long time, symptoms of bladder neck obstruction will appear, leading to dysuria and obstruction, or urinary leakage and incontinence.

Urinary retention is also easy to cause complicated infection and stones, and will also affect renal function in severe cases. 12. Take a nap at your desk. Most people will have temporary blurred vision after taking a nap at your desk. The reason is that the eyeball is compressed, causing corneal deformation and curvature change.

If you press your eyeball every day, the intraocular pressure will be too high, and if this continues, your vision will be damaged. 13. Lying prone makes the spine bend, which increases the pressure on muscles and ligaments, making people still unable to rest while sleeping.

In addition, it will increase the pressure on the chest, heart, lungs and face, leading to facial edema and bloodshot eyes after waking up. 14. If you don't wash your face before going to bed, the cosmetics left on your face will cause inflammation such as acne and pinholes, and it will also make your eyes inflamed and cause skin allergic reactions.

Sleeping late will inhibit the cerebral cortex for a long time, which will cause a certain degree of artificial brain dysfunction, lead to a decline in understanding and memory, and also reduce immune function, disrupt the biological rhythm of the body, make people lazy and inert, and at the same time, it is not good for muscles, joints and urinary system.

In addition, poor blood circulation and untimely systemic nutrition delivery will also affect metabolism. Because the doors and windows are closed at night to sleep, the indoor air is cloudy in the morning, and falling in love with the bed is easy to cause respiratory diseases such as colds and coughs.

17. The hot water bath time is too long. In tap water, chloroform and trichloroethylene are harmful substances that are easy to volatilize in water. Because there are more opportunities for water droplets to contact the air during bathing, these two harmful substances are released a lot. According to the collected data, only 25% chloroform and 40% trichloroethylene are released into the air if hot water bath is used. Bathing with hot water will release 50% chloroform and 80% trichloroethylene into the air.

18. Gambling is harmful to a person's physical and mental health, because gambling itself is a strong * * *. Long-term gambling will make the central nervous system in a state of high tension for a long time, which will easily lead to increased hormone secretion, vasoconstriction, increased blood pressure, and accelerated heartbeat and breathing.

Knocking teeth method: first concentrate your thoughts, shut your mouth slightly, and then knock each other with your upper and lower teeth dozens of times. All teeth should touch each other, not too hard, to prevent biting the tongue.

Frequent knocking at the door can strengthen the firmness of teeth, make teeth not easy to loose and fall off, strengthen chewing power and promote digestive function.

Drum gargle method: gnash your teeth, your mouth is like a thing, and you can do dozens of actions with your cheeks and tongue. When you rinse your mouth, there will be more saliva in your mouth. When the saliva is full, you swallow a few more slowly. There may not be much body fluid at first, but it will naturally increase after a long time.

Drum washing is mainly to make the mouth produce more body fluids, which can help digest and clean the mouth, exercise the surrounding muscles and make the cheeks full.

Tongue transport method: use your tongue to rotate back and forth in the mouth, outside the teeth, left and right, up and down until it increases, and then wash the remaining one or several mouthfuls and swallow it.

Moving tongue can effectively prevent and treat oral mucosal diseases and atrophy of tongue body in the elderly, and can increase saliva secretion and moisten gastrointestinal tract.

When the bristles are relaxed, the local blood vessels dilate and congestion, which is repeated several times to improve blood circulation and enhance resistance. The other is to use the index finger as the gum. After gargling, put the clean right index finger on the gingival mucosa, rub it up and down along the gingival level from the root to the crown, back and forth, and then up and down the inner and outer gums, for about a few minutes. Through the gums, increase the blood circulation of gingival tissue.

6. Safety knowledge lecture 100 to 200 words.

It's safe with me.

Life is precious, but it is also fragile. Any minor injury may make it incomplete or terminated, just like a little gauze. Youxue. com has compiled a 200-word composition on safety knowledge for everyone: the experience of safety education. I hope the students pay attention to safety.

This Saturday, I watched the safety education TV program. The program is divided into five parts: earthquake, fire, drowning, flood and traffic accident. I am most concerned about the part about traffic accidents.

Traffic accidents are about safety knowledge on the road. For example, don't run around on the motorway, don't ride a bike on the motorway, or stop, and don't climb over the railing in the middle of the driveway.

The main ways to prevent fire are: don't light candles and read books at night, and don't play with open flames. If you find yourself on fire, you can only roll on the ground quickly if you can't run fast.

When the earthquake comes, protect your head and quickly hide under objects that are not easy to collapse. If you are buried under the rubble, don't shout, knock on the door to attract the attention of rescuers. If possible, you can supplement food or water appropriately.

In this project, I learned a lot about safety.

The safety education experience ends here. I hope every reader can understand safety after reading it. Life is precious and fragile. Be sure to pay attention to the safety of yourself and your family!

A: Japanese experts recently found that beta carotene can regulate the balance of histamine in blood, so eating carrots can effectively prevent allergic reactions such as pollen allergy and allergic dermatitis.

Strawberries have anti-cancer effects. Chinese medicine believes that strawberries have the effects of stimulating appetite, calming the liver and benefiting the lungs. In recent years, medical scientists at home and abroad have found that it is beneficial to the heart and brain, and is of great significance to the prevention and treatment of atherosclerosis, coronary heart disease and cerebral hemorrhage.

Adding sugar to dairy products is beneficial to calcium absorption. Japanese scientists have found that calcium carbonate contained in foods such as milk is not easily absorbed by the small intestine, but after eating sugar, bacteria in the small intestine will produce lactic acid, which can promote the absorption of calcium by the human body and increase the absorption of calcium by the small intestine by about ten times.
