Stretching can delay aging, have you got it?

  Why do people stretch?

  The so-called stretching is an action of raising the upper limbs over the chest or head. Some people think that stretching one’s waist is a kind of laziness. In fact, this understanding is incorrect. Stretching is sometimes an unconscious behavior. When tired, it is unconsciously stretched. This is because the oxygen content of the limbs and tissues is reduced due to long periods of non-exercise, and the brain actively sends out this signal. Basically, spinal animals can stretch their waists when they breathe with their lungs. This is an instinctive reaction, just as yawning is an instinctive reaction. Even when you are not tired, you will feel comfortable if you consciously stretch your waist a few times. Stretching the neck and raising the arms to stretch the waist in public places, although it seems to be out of grace, it is really good for the body.

   So what is the advantage of stretching?

   When stretching the waist, raise the arms, recline the body, contract muscles, expand the chest cavity, improve heart and lung functions, and improve blood circulation. Not only is the nutrient supply sufficient, but metabolites can also be eliminated in time; at the same time, chest expansion can also be used Breathing in more oxygen will increase the metabolism of the body, improve the work efficiency of the brain and other organs, and reduce fatigue. In addition, the activities of the upper limbs and upper body can make more oxygenated blood supply to the brain, making people feel awake and comfortable immediately. The sense of comfort comes from the cells being provided with a large amount of oxygen in a short time, so stretching one’s waist when sleepy will make people feel awake and comfortable immediately. There is another proverb spread among the folks: “Stretching often is an ancient teaching, to relieve fatigue and nourish the heart.” Frequent stretching and movement of limbs are good for relieving fatigue, and it is also one of the “magic weapons” for office white-collar workers to maintain vigorous energy.

   Summary: Stretching, simple and easy, suitable for all ages, without a teacher. After heavy work or sitting or lying for a long time, stretch out a few lazy waists comfortably between long office hours, which not only eliminates fatigue, but also shapes your body. The effect is good, and you can gain health easily. When stretching, stretch your body as much as possible, straighten your limbs, and exert all your muscles. When stretching, inhale as much as possible; when relaxing, the muscles of the whole body should relax and exhale as much as possible, so that the effect of exercise will be better. For the elderly, doing this exercise regularly can also increase the elasticity of muscles and ligaments and delay aging. Everyone, get up and stretch frequently.

“Head down family” do more of these three actions

   Coming to and from work and squeezing the subway, have you noticed that everyone is busy, looking down at the phone, playing games, reading certain treasures, reading e-books… Pan Cuihuan, chief physician of the Rehabilitation Department of the Second Affiliated Hospital of Guangzhou Medical University, said, bowed his head Clan playing with mobile phones with chest and hunchback for a long time, the cervical spine always maintains forward flexion, and the neck, shoulder and chest muscles are in a state of tension for a long time.

Disorders, cervical muscle strain, cervical spondylosis and other diseases.

   She suggested that daily stretching of the neck muscles can effectively relieve muscle fatigue and soreness caused by long-term bowing, and activate the deep stable muscles of the neck. Stretching the chest muscles can help improve posture and avoid the health caused by poor posture. problem.

   So, don’t use your phone to be a “head-down clan” on the subway. You can seize the time to secretly do these three actions.

Bitter mouth in the morning, soothing the liver and regulating emotions

   Hubei reader Mr. Wang asked: I always feel bitter when I wake up in the morning. My friend said that the moisture in my body is too heavy. How to deal with this situation?

   Quan Yihong, director of the Department of Traditional Chinese Medicine of Wuhan Central Hospital, answered: The bitterness of the mouth in the morning is not necessarily caused by heavy humidity. Mouth pain is a common clinical disease in Chinese medicine, with liver heat, gall bladder heat, and heart heat as the main causes, and it is also closely related to emotions, emotions and other aspects.

   Chinese medicine believes that pain in the mouth is closely related to the “liver” of the viscera. The liver controls drainage, has the functions of dredging the qi machine, reaching all parts of the body, promoting the circulation of essence, blood and body fluid, the lifting and lowering of the spleen and stomach, the secretion and excretion of bile, and the effect of relaxing emotions and emotions. If the liver is hot and the liver is hot, it will affect this series of functions, and then induce the symptoms of bitterness in the mouth. At the same time, bitterness is also related to emotions. As the pace of life accelerates, people’s mental stress continues to increase, and personal emotions are getting more and more easily out of control. People who suffer from pain in the mouth gradually show the characteristics of emotional illness. Liver qi is upset and depressed, emotional dissatisfaction, liver qi stagnation, it will lead to violent attacks on the stomach, causing the stomach to lose harmony, and the bile overflows and the mouth is bitter. Therefore, people with painful mouth symptoms must pay attention to regulating their emotions, face the trivial matters in life with a normal heart, and keep their moods comfortable. For the conditioning of mouth pain symptoms, I would like to recommend some small methods for everyone:

   People with mild symptoms can drink tea. Corn silk tea: take 30 grams of corn silk and 10 grams of green tea and soak in water, which can clear dampness and heat, and promote liver and gallbladder. Cassia rose chrysanthemum tea: take 10 grams of roses, 15 grams of cassia seeds, and 10 grams of hangbai chrysanthemum soak in water to soothe the liver, regulate qi, and relieve depression. Banlangen chrysanthemum drink: Take 30 grams of Banlangen and 10 grams of chrysanthemum soak in water to clear the heat of liver and gallbladder.

   Those with severe symptoms can take diet therapy. Chrysanthemum, barley and winter melon syrup: 15 grams of chrysanthemum, 30 grams of barley, 100 grams of winter melon, 15 grams of sugar, add water to boil the chrysanthemum and barley for 30 minutes, remove the two medicines and leave the juice, add winter melon to the soup, add sugar to the soup. Winter bamboo shoots and mushroom soup: 250 grams of winter bamboo shoots, 50 grams of shiitake mushrooms, wash and shred the winter bamboo shoots, slice the shiitake mushrooms, put them in the pot and stir-fry for about 20 minutes, then add water and seasonings to a boil. Yellow flower porridge: 30 grams of day lily, 15 grams of lean minced meat, appropriate amount of glutinous rice, add water to the above ingredients and cook into a porridge.

   If none of the above methods can be relieved, you can take proprietary Chinese medicines under the guidance of a doctor. Xiao Chaihu Tang Pills can be used for bitter mouth syndrome of gallbladder-heat syndrome, and Longdan Xiegan pills for liver-gallbladder stagnation-heat syndrome. People with liver and gallbladder stagnation and heat syndrome can also use the middle finger to rub the acupoints of Yanglingquan and Ququan, 50 strokes each time, 2 times a day. It is better to have soreness and swelling. . You can also tap the gall bladder meridian when you wake up in the morning. The gall bladder meridian is located on the outer side of the thigh. Every 4 beats counts once, and the left and right thighs are beaten 50 times a day, which is 200 on the left and right. When beating, the intensity should be moderate. It is normal to feel soreness after beating. In addition, those with a bitter mouth should avoid spicy, fried, barbecued and other hot products in their diet. They can eat more soups and light meals.

Seeing Qi and Blood and Viscera from the Gum

  Gum is the soil for tooth life, gum health determines tooth health, and the importance of teeth to life is self-evident. The old saying goes: “Hundreds of things keep in good health, don’t fix your teeth first.” The role of the gums is to take care of the teeth and assist in chewing. Therefore, to maintain the normal physiological function of the gums is to protect our health. How can I judge the health of my gums and understand the health code hidden in my gums? In fact, you can know a thing or two from the color of your gums.

   Common gum colors are pink, dark red, dark purple, light white and bright red. Pink is the natural color of gums and the healthiest color. The abnormal color of the gums caused by the disease is different according to the syndrome differentiation of TCM.

   Gum is bright red: the stomach is burning. Excessive heat evil in the stomach, stomach qi disorder, hyperfunction, inflammation of the stomach, and excessive heat injure the body fluid will cause the gums to appear bright red, and in severe cases, gum bleeding may occur. At the same time, it is accompanied by periodontal or gum pain, yellow and thick tongue coating, dry mouth, short temper and so on. For this situation, periodontal curettage is usually used, that is, the use of traditional Chinese medicine to eliminate local inflammation of the gums. At the same time, use traditional Chinese medicine for clearing away heat and detoxification and purging stomach fire to make a decoction (10 grams of skullcap, 10 grams of clove leaves, 15 grams of forsythia, 15 grams of honeysuckle) morning and evening, gargle or take it orally.

   pale white gums: Qi deficiency. Chinese medicine believes that one can know Qi and blood by looking at the gums. The gums are very easy to observe the qi and blood. If the qi and blood are insufficient and the body is weak, the color of the gums is mostly pale white. It is often manifested as early morning phlegm, dark red saliva in the mouth, and the appearance of the tongue is fat, tooth marks, and white fur. At the same time, it is accompanied by Qi deficiency symptoms such as lack of energy, insomnia, and soreness in the waist and knees. To regulate qi deficiency, drugs with qi tonifying effects can be used, such as ginseng, American ginseng, Codonopsis pilosula, Taizi ginseng, Poria, Chinese yam, Atractylodes, Astragalus, Ganoderma lucidum, Jujube and other Chinese herbal medicines. People with qi deficiency should usually take part in more exercises to strengthen their physical fitness. Traditional fitness methods are most suitable, such as Tai Chi and Tai Chi swords. In the diet, eat more qi foods, such as millet, glutinous rice, lentils, carrots, tofu, sweet potatoes, chicken, pork belly, potatoes, mushrooms, etc.

  Dark red gums: Yin deficiency. The color of the gums of people with yin deficiency physique is dark red, often accompanied by symptoms such as irritability, more night dreams, hot hands and feet, less saliva in the mouth, and always feel dry mouth. Zhu Danxi, the leader of the “Four Great Masters of the Jin and Yuan Dynasty” and the founder of the yin nourishing school, pointed out: “Human, yin is always insufficient, but yang is always surplus; yin deficiency is difficult to treat, and yang deficiency is easy to make up.” Winter, white fungus, duck pear, duck meat, mulberry and other medicines and foods of the same origin can nourish yin and nourish body fluid. People with yin deficiency physique are more impatient and easy to get upset and anger. This is due to yin deficiency and fire, which disturbs the gods. Therefore, they should follow the method of “tranquil emptiness” and “spiritual guarding”. At work, I should avoid arguing with others for non-principle issues to reduce irritation. During the holidays, you can go to the countryside and stay away from the hustle and bustle of the city.

   dark purple gums: blood stasis. In people who have suffered from periodontal disease for many years and are older at the same time, the color of the gums can be dark purple, clots or blood stasis can be seen on the gums, and the tongue coating is yellow or white coating. This condition appears to be of blood stasis type in Chinese medicine. These people will also show some symptoms of blood stasis, such as dizziness, dark complexion, dark lips, etc. Older people have coronary heart disease, often precordial tingling and other symptoms, accompanied by toothache and other symptoms. People with blood stasis can often eat hawthorn slices and drink wine in moderation to invigorate blood and remove blood stasis and improve blood circulation. Appropriate exercise is also important, it helps to regulate blood stasis. It is recommended to dance, practice Tai Chi, practice Ba Duan Jin, etc. People with blood stasis physique need to cultivate optimism in mental health care. A happy spirit leads to a smooth flow of qi and blood, circulation of camp and health, which is beneficial to the improvement of blood stasis physique.

   I need to be reminded that abnormal gum color does not necessarily indicate physical illness, and certain objective factors can also cause it. For example, people in some areas, due to special water quality (high fluorine, high calcium, heavy metal pollution), the color of the gums will have some pigmentation, which can be dark purple, brown, dark red, light white or light yellow. There are also people with thinner gingival mucosa, the gums and bone walls are close together, and the gums are pale white. These conditions are still normal gums, don’t worry too much.

Why is the mouth dry in winter? These methods can alleviate

   In winter, as the climate becomes dry, people will feel more or less dry mouth and tongue, and even worse, it will be accompanied by bitter mouth, worsening bad breath, oral ulcers, and constipation. And many other symptoms occur.

  Why is it so easy to feel dry mouth in winter? Chief physician Weng Zhiqiang of the Second Affiliated Hospital of Guangzhou Medical University explained that on the one hand, the climate becomes dry and the moisture evaporates too quickly, which aggravates the original dry mouth and makes the symptoms more obvious; on the other hand, the dryness evil in winter consumes yin, which can also cause dry mouth. Various symptoms of discomfort appear.

  Dry mouth is divided into physiological and pathological characteristics

   Dry mouth is not an independent disease, it is a group of symptoms including physiological and pathological causes. Weng Zhiqiang said that dry mouth is divided into two types: physiological and pathological——

   Physiological dry mouth: People who drink less water daily, and eat salty food or a lot of dry food; the elderly, various functions are degraded, fluid secreting glands are atrophy, saliva is reduced, and different degrees of dry mouth appear; Dry mouth will also occur if you do not replenish water in time after exercise.

  The cause of dry mouth is complicated, drinking water alone is not effective

   There are many reasons for dry mouth. Some are caused by poor diet, psychological and physical habits, and some are caused by diseases. In order to alleviate dry mouth, increasing the amount of drinking water can only relieve people who drink too little or too much water, but it is often difficult to effect dry mouth caused by various diseases.

   Weng Zhiqiang reminded that dry mouth cannot be relieved in a short time, especially if the symptoms are more than three months, you should go to the hospital for a comprehensive examination.

   There are the following methods to prevent dry mouth every day:

   (1) Keep your mouth clean and rinse your mouth frequently to reduce the possibility of dental caries and secondary oral infections.

   (2) Prevent colds, maintain optimism, relieve stress and pressure at work, and avoid anger, anger and irritability.

   (3) In the dry winter, pay attention to dietary conditioning and eat more lung and yin foods and fruits, such as honey water, ginseng fruit, Sydney, grapes, etc., which can not only relieve dry mouth and tongue, but also prevent constipation.

   (4) Keep going to bed early and getting up early, take part in outdoor physical exercise, eat regularly, quit smoking, and avoid alcoholism.

Eating dinner too late will cause indigestion, easy to get fat and stone

  Many people can’t eat dinner on time due to work or other reasons, and often have to delay it until late in the night. Experts remind that eating too late for dinner will increase the burden on the stomach and intestines, making the food unable to be digested and absorbed, leading to indigestion, and it is easy to gain weight.

   Also, because the body’s peak calcium excretion period is between 4 and 5 hours after a meal, if you fall asleep after eating dinner too late, the body’s urine cannot be excreted in time, and the body’s calcium cannot be excreted in time with the urine. The precipitation over the years will increase the possibility of getting stones.

Great cold regimen: refreshing and restraining your breath, don’t overdo it

   Beijing, January 20 (Reporter Guo Jun) “Great Cold” is the sixth solar term in winter and the last of the 24 solar terms. It is not only the end, but also means that the new year is coming. Dahan meets Lichun, so it is slightly different from Xiaohan in terms of diet and health.

  Spirit: Feel comfortable

  During the severe cold season, we should rest assured that we should be calm and refreshed, especially the elderly, because this year’s severe cold coincides with the Spring Festival and the children and grandchildren are full. At this time, we should also pay attention to avoiding joy or sadness and reducing heart and brain diseases. occur. Attention should be paid to maintain a comfortable mood and a peaceful state of mind, so that the qi and blood in the body are harmonious, and the yang qi hidden in the body is not disturbed, so that “righteous qi is stored in the body, and evil is not allowed.”

   Daily life: go to bed early and get up late

  ”Big Cold” is the last solar term in winter. In terms of daily life, it must still conform to the characteristics of winter closure, so that it can go to bed early and wake up late. Going to bed early is to nourish the body’s yang, and getting up late is to nourish yin. On the other hand, there is an old saying: “Big cold and big cold, protect against wind and cold.” In the cold season, in addition to paying attention to the cold, you must also protect yourself from the wind. Clothing should increase or decrease with temperature changes. Your hands and feet are easy to freeze, and you should pay special attention to keeping warm.

  Life: Washing feet before going to bed can dilate blood vessels

   As the saying goes, “The cold starts from the feet, and the cold comes from the legs.” When a person’s legs and feet are cold, the whole body is cold. “Three hundred steps after a meal, a pot of soup before going to bed”, soak your feet with hot water before going to bed, can dilate blood vessels, speed up blood flow, improve the nutrition of the skin and tissues of the feet, reduce muscle tension, improve sleep quality, and prevent Both feet freezing and disease prevention and health care are beneficial, especially those who love to read and write at night and sit for a long time until late at night. They should soak their feet in hot water before going to bed.

  Exercise: exercise after sunrise, can’t overdo it

   As the saying goes, “If you move in winter, you don’t have a disease; if you are lazy in winter, drink a bowl of medicine.” Winter activities and exercise have special significance for health preservation. Sports in the cold season can be divided into indoor and outdoor sports. Jogging, Tai Chi, Baduan Jin, basketball and other physical exercises can be performed. Outdoor activities should not be up too early. It is better to wait after sunrise.

   Do not over-exercise, sweat too much, and avoid damage caused by yang qi coming out with sweat. Exercise intensity is determined according to your physical condition. Slight sweating is best, haze and snowy days, and it is best to stop exercising.

   Food tonic: Consolidate the spleen and kidneys, regulate the liver and blood. It is not suitable to eat hot and dry things

   Keeping in good health should follow the laws of nature, focusing on conserving yin and protecting yang. It is recommended to eat hot, not to eat cold, sticky, hard and difficult to digest foods to prevent damage to the yang qi of the spleen and stomach, and do not eat too much hot things.

   Diet should reduce saltiness and increase bitterness in order to nourish the heart qi and strengthen the kidney qi. Avoid hard and cold foods. Eat hot food to prevent damage to the yang qi of the spleen and stomach, but do not overeat hot and dry foods. The taste of the food should be moderately strong. , There must be a certain amount of lipids and maintain a certain amount of calories. In addition, you should also eat more yellow and green vegetables, such as carrots, rape, spinach and so on. In addition, because the cold falls in the Spring Festival, most families will prepare abundant food for the New Year. At this time, they should pay attention to avoid hunger and satiety. At the same time, they can eat more foods with the effect of invigorating the spleen, such as yam, hawthorn, grapefruit, etc. You can drink more, such as millet porridge, spleen-tonifying dampness porridge, etc. for conditioning.

   does not damage Yin Jin

   Another important point of health preservation during the severe cold is to nourish yin. Generally, the precipitation in the Yangtze River Basin begins to decrease from the winter solstice. After a month, the severe cold solar term is the driest period. The average air humidity during the day is generally lower than 50%, and sometimes the indoor humidity is only about 30%.

   As the water vapor between the heaven and the earth decreases, the yin fluid in the human body will easily become insufficient. Many people with chronic respiratory diseases often have a feeling of coughing or thick sputum and unclean sputum. Patients with cardiovascular disease are more likely to increase blood viscosity. If blood vessel elasticity decreases due to high blood pressure, old age, etc., it is more likely to induce dangerous conditions such as myocardial infarction, cerebral infarction, and cerebral hemorrhage.

   In terms of living, if the indoor heating or air conditioning is often turned on, in addition to frequent ventilation, it is best to use some air humidifiers to increase the humidity in the air. If you use electric blankets to sleep at night, try not to turn on Overnight or open too hot. Increase the amount of water you drink as much as possible, and do not wait until your mouth is dry. Drink a glass of warm water every day before going to bed and after getting up. It is best to drink a little water before and after bathing to replenish the lost water.

  What kind of fruit is good for the cold solar term

  1, pear

  In winter, it is most prone to dry lips and thirsty and dry skin. Chinese medicine believes that pears are slightly cold in nature and sweet in taste, which can produce body fluids to quench thirst, moisturize dryness and relieve phlegm, moisten the intestines and lax. It is now the season to eat pears. Pears, known as the “sect of all kinds of fruits”, have pear juice that has a unique effect on dryness in autumn and winter. Especially suitable for people who are hot in winter.

  2, persimmon

   The vitamins and minerals in persimmon are good for beauty. The content of vitamin C in red persimmon is 10 times that of apples, which can prevent colds. At the same time, it is rich in vitamin A, which can prevent a variety of eye diseases. Secondly, red persimmons are rich in carotene. Each 100 grams of red persimmons contains 139 mg of carotene, which is 13 times that of peaches and 2 times that of melons. Carotene can prevent aging and fight cancer.

  3, grapefruit

   grapefruit is the best fruit in winter. It has the functions of invigorating the stomach and eliminating food, resolving phlegm and relieving cough, etc. It is often consumed and has auxiliary treatment effects on hypertension and diabetes. The high vitamin C content of grapefruit can prevent colds and beautify the skin. There are fewer types of fruits and vegetables in winter than in other seasons, and grapefruit can provide us with sufficient vitamin C in winter. The VC content of grapefruit is as high as 23mg. Vitamin C can not only enhance immunity, but also promote collagen synthesis and beautify the skin.

Keep drinking tea to reduce the risk of cardiovascular and cerebrovascular diseases

   Recently, the team of academician Gu Dongfeng from Fuwai Hospital of the Chinese Academy of Medical Sciences published a research paper in the European Journal of Preventive Cardiology, showing that regular tea drinking can reduce cardiovascular and cerebrovascular events and all-cause deaths Occurrence risks, especially for people who insist on long-term tea drinking habits, male tea drinkers, and green tea drinkers, the health benefits are more significant.

   The research team tracked the health outcomes of the study subjects for up to 17 years, and found that compared with those without the habit of drinking tea, the risk of onset of cardiovascular and cerebrovascular disease, death from cardiovascular and cerebrovascular disease, and total death were decreased in regular tea users, respectively. About 20%, 22% and 15%. In other words, for the 50-year-old people, the time of cardio-cerebrovascular disease is delayed by 1.41 years and life expectancy is prolonged by 1.26 years. The study further used the information of the two tea-drinking habits surveys of 14081 subjects after 8.2 years. The analysis found that compared with those who never drink tea, those who persisted in drinking tea for a long time had the onset of cardiovascular and cerebrovascular disease, the death of cardiovascular and cerebrovascular disease and the whole The reduction in the risk of death was even more significant, with the reduction rates being 39%, 56% and 29%.

   Among the subtypes of cardiovascular and cerebrovascular diseases, the study found that the habit of drinking tea has a better protective effect on stroke and coronary heart disease and stroke death. The analysis based on the type of tea drinking showed that the risk of cardiovascular and cerebrovascular disease deaths and all-cause deaths in people accustomed to drinking green tea was significantly reduced, and it was not found that regular black tea has a significant protective effect. In addition, the study also found that the protective effect of tea drinking is more significant in men. This may be due to the high proportion of men drinking tea and the significantly higher incidence of cardiovascular disease than women, making it easier to observe the health effects of tea drinking in men. .

   Researchers believe that the mechanism by which tea drinking is beneficial to health may be related to the rich tea polyphenols. Tea polyphenols are the main biologically active substances in tea. They have anti-inflammatory, antioxidant, blood pressure and blood lipid effects. Among all types of tea, green tea has the highest content of tea polyphenols; during the fermentation process, tea polyphenols will be oxidized and lose activity, resulting in a decrease in the content of tea polyphenols in black tea. In addition, tea polyphenols are metabolized quickly in the body and cannot be stored for a long time. Therefore, it is necessary to maintain the habit of drinking tea for a long time to benefit from it. (Reporter Wang Xiaoyu and Wang Dan)
