Food cleanses the lungs? In traditional medicine, \”clearing the lungs\” generally refers to relieving symptoms related to the respiratory tract, such as cough, excessive phlegm, etc. Some medications and foods can help relieve these symptoms and are therefore known as \”lung-clearing foods.\” But it is nonsense to say that this kind of \”lung-cleansing\” food can clean \”air-polluted lungs.\”
Cramps and calcium deficiency? Although calcium deficiency does cause cramps, this happens more often in middle-aged and elderly people with osteoporosis and pregnant women. If other people have cramps, don\’t rush to supplement calcium. First understand what type of osteoporosis you have. Only people who suffer from cramps can get rid of the torture of cramps.
Drink to keep warm? \”Here, take a sip of wine to warm yourself up.\” Several people shivered in the cold wind, handed the bottle to one person, and then exhaled with satisfaction. This behavior of drinking liquor to keep out the cold is common in life. But in fact, under the stimulation of alcohol, blood vessels cannot contract in time, which will also hinder the blood from transporting heat outward. After a large amount of body heat is lost, a person will feel colder.
Becoming stupid after pregnancy? After pregnancy, a woman\’s body will undergo tremendous endocrine changes. Estrogen, thyroxine, progesterone, etc. filter cells throughout the body from the head to the organs. After this process, women will not become stupid, but will become smarter, more beautiful, wiser and more charming.

Eating fungus regularly can clear the lungs
The lingering smog has also given rise to a number of folk remedies for clearing the lungs. The most striking thing is that eating fungus regularly can clear the lungs. The evidence seems conclusive: Because fungus is rich in cellulose and plant pectin, it has the effect of moistening the lungs and cleansing the stomach. However, experts say this argument does not have sufficient theoretical basis.
There are black and white fungus. We often eat black fungus. Yang Baolin, chief physician of the emergency department of Dongzhimen Hospital of Beijing University of Chinese Medicine, reminded that traditional Chinese medicine teaches that white enters the lungs and black enters the kidneys. Therefore, black fungus has nothing to do with clearing the lungs. Maybe eating white fungus is better for the lungs.
More importantly, so-called \”lung-clearing foods\” such as pears, rock sugar, white fungus, and radish also have a \”lung-clearing\” effect in traditional medicine. In traditional medicine, \”clearing the lungs\” generally refers to relieving symptoms related to the respiratory tract, such as cough, excessive phlegm, etc.
The main damage caused by haze to the lungs is that pollutants in the air enter the alveolar terminals in the form of small particles, damaging the lungs and causing inflammation. The ancients probably were not aware of air pollution when they prescribed \”Qingfei Prescription\” or \”Qingfei Prescription\”. Therefore, it is nonsense to say that \”lung-cleansing\” foods can clean \”air-polluted lungs\”.
Director Yang Baolin said that improving one\’s own immunity, trying not to go out in hazy days, and not opening windows for ventilation are the basic methods to prevent and control haze.
Drink white wine when it\’s cold
\”Here, take a sip of wine to warm yourself up.\” Several people shivered in the cold wind, handed the bottle to one person, and then exhaled with satisfaction. This is a scene that often appears in movies, but in real life, drinking liquor to keep out the cold is common.
\”It is not advisable to drink white wine alone to keep out the cold, as there is a certain risk.\” Wang Yan, a nutritionist at the Nutrition Department of Jiangsu Provincial Hospital of Traditional Chinese Medicine, said that drinking white wine can make the body feel warm because the alcohol in white wine can dilate blood vessels. Accelerate blood circulation, allowing blood stored in the liver and other parts of the body to flow to the surface of the body, so that only the epidermis of the skin feels warm. Moreover, due to the accelerated heat dissipation of the body, the heat lost is more than the heat supplied by alcohol, and people will feel colder. This is what the folks call \”drunk cold\”.
After drinking, the body surface becomes hot and the pores open, making you vulnerable to cold air. The alcohol in liquor can also paralyze nerves and reduce people\’s sensitivity to cold. If it is cold outside, accidental injuries such as frostbite may easily occur.
Wang Yan suggested that you should exercise moderately in winter to enhance your physical fitness and eat a balanced diet. You can eat more warm foods, such as mutton, red dates, longan, etc., which is a more suitable way to warm up.
Cramps are caused by calcium deficiency
The TV commercial says: \”Back pain and leg cramps are your body\’s reminder of calcium deficiency!\” Is that true?
Li Jianmin, chief physician of the Department of Orthopedics of Traditional Chinese Medicine at Beijing Jishuitan Hospital, told reporters that the statement that \”leg cramps are caused by calcium deficiency\” is too general. Although calcium deficiency does cause cramps, this happens more often in middle-aged and older people with osteoporosis. For people and pregnant women, if others have symptoms of cramps, do not rush to supplement calcium. It is more accurate to know what type you have.
In addition to calcium deficiency, common causes of frequent cramps include:
Muscle tension caused by prolonged walking and standing forces the muscles to engage in compensatory behavior, with rapid contractions leading to a twitching response. Cramps in this condition can be relieved by stretching and adding salt water.
In a cold state, muscles will contract due to lack of heat, and we will shiver when we are cold. This is a natural reaction of muscles to twitch to keep the limbs warm. Therefore, when it is cold outdoors or at night, those prone to cramps should keep warm to reduce irritation.
Muscle injuries such as thighs and calves are more sensitive and willCramps easily afterwards. During the muscle recovery period, the injured person should immobilize the injured area, properly massage the painful area, promote blood circulation, and exercise step by step until recovery.
There are also many young people who do not exercise and suffer from cramps. Director Li Jianmin suggested that young people exercise more, increase muscle elasticity, improve physical fitness, and pay special attention to improving cold resistance and endurance. However, do not engage in strenuous exercise when you are not in good physical condition, especially when you are tired and hungry.
Don\’t stress when cramps appear suddenly. Usually, you only need to stretch the spasmed muscles in the opposite direction, and the pain all over the body can be relieved. If the cramp lasts for a long time, you can use hot or cold compresses to relieve the pain, or spray or apply some muscle-relaxing, pain-relieving lotion or ointment on the local area, which is also very effective.
> Pregnancy makes you stupid for three years
She is careless, forgetful, and slow to react. When pregnant women have these problems, people always joke and say, \”Sure enough, she is stupid for three years.\” ! \”It is true that many women suffer from problems such as inattention, forgetfulness, and postpartum depression during pregnancy, but this phenomenon of appearing stupid does not mean a decline in intelligence,\” said Tsinghua University School of Medicine, Vice Dean, Aviation Cao Zeyi, honorary president of the General Hospital, analyzed. Many scientific studies have also confirmed this. For example, in 2010, Helen Christensen et al. published an article in Br J Psychiatry entitled Cognition in pregnancy and motherhood: prospective cohort study (Prospective cohort study on cognitive function during pregnancy and motherhood) ) article stated: No matter during pregnancy or after pregnancy, short-term or long-term, there is no significant change in women’s cognitive function.
Pregnancy and childbirth are not an easy task. Many pregnant women will inevitably be a little more nervous than usual during pregnancy, such as worrying that the child will be unhealthy and not having helpers to take care of the child. After the child is born, especially in the first two months In the new year, mothers have to become more versatile, feeding, changing diapers, putting them to sleep, etc., so that the pregnant woman\’s attention is completely transferred to the child, and other trivial matters become no longer important, so it is natural to forget easily. This may This is the origin of \”one pregnancy makes you stupid for three years\”.
After pregnancy, a woman’s body will undergo huge endocrine changes. Estrogen, thyroxine, progesterone, etc. will filter all the cells in the body from head to organ. After experiencing this process, a woman will be considered mature. Only then can a woman truly behave. “It can be said that after a woman gives birth to a child, not only will she not become stupid, but she will become smarter, more beautiful, more intelligent, and more attractive. Women who do not have children often enter menopause early and are prone to aging and disease,\” Cao Zeyi explained. \”So the consensus in our medical community is that a woman must have a child, and it is best to do it before the age of 30.\”
Looking at green can protect your eyes
We have been warned by teachers since childhood to look at green plants in the distance after reading and writing for a period of time to prevent myopia. Now we are reminded by colleagues around us that changing the computer wallpaper to green is the best way to protect our eyes. Regarding this statement, Yang Yingxin, director of the Ophthalmology Department of Beijing Hospital of Traditional Chinese Medicine, explained that cyan and green have moderate absorption and reflection of light, and have less stimulation to the human nervous system, cerebral cortex and retinal tissues, so they can bring A cool and calm feeling, but this does not mean that it can combat visual fatigue and prevent myopia.
When looking at the computer for a long time, contrast is one of the important factors that determine whether your eyes will easily feel tired. From experience, the contrast between black text on a white background is the most obvious, and it is easy to feel tired after a long time, while light green is softer. Changing the computer wallpaper to a soft green only makes the screen brightness less dazzling, but it can also cause dry eyes caused by too few blinks and rapid evaporation of tears, visual fatigue, and neck and shoulder pain caused by problems such as sitting posture and distance from the screen. , has no effect.
Looking at green plants in the distance to relax your nervous eyes is a reliable way to prevent myopia and relieve eye fatigue, but it should be noted that this does not mean that green itself is good for the eyes. , but it means that the action of \”looking into the distance\” to focus far away can make the ciliary muscles relax and give the eyes a rest.
Looking at things within 30 centimeters, such as green plants next to the computer, is not good for your eyes. Therefore, Director Yang Yingxin reminded that if you believe that green can protect your eyesight, it is better to look out the window more.
Strong tea can relieve hangovers
Rumors about strong tea’s ability to relieve hangovers have always been heard, and rumors have been repeatedly refuted.
\”Theophylline in strong tea has a strong diuretic effect. Drinking too much will increase the number of trips to the toilet, so many people think that drinking wine can be excreted in time.\” Wu Tao, a nutritionist in charge of the nutrition department of Beijing Tongren Hospital, said that this is actually an illusion. In fact, strong tea cannot relieve hangover in time, and drinking a lot of strong tea after drinking can damage the heart and kidneys.
The main component of wine is alcohol, which is ethanol. Ethanol can speed up blood flow and heartbeat. The caffeine in strong tea can also have an exciting effect on the heart. Drinking both before and after will enhance the stimulation of the heart. . In addition, ethanol enters the blood and is first converted into acetaldehyde in the liver, which is then converted into acetic acid, and finally decomposed into carbon dioxide and water and excreted from the body. The main sour substance in vinegar is acetic acid. Acetic acid itself is harmless to the human body; but acetaldehyde is very harmful to the human body. Symptoms such as blushing, dizziness, nausea, and body aches after drinking alcohol are all caused by the accumulation of acetaldehyde in the body. . If you drink strong tea after drinking, the diuretic effect of theophylline will cause the unconverted acetaldehyde to enter the kidneys prematurely, thus affecting kidney function. Therefore, drinking strong tea after drinking often can easily damage the kidneys. As early as 2007, a report by the International Agency for Research on Cancer also clearly stated that acetaldehyde produced in drinking alcohol can cause esophageal cancer.
“Eat some staple food and vegetables before drinking.Food, drink more water during drinking, and drink some honey water in moderation after drinking can dilute the alcohol concentration and alleviate the irritation of alcohol to the stomach, but alcohol’s damage to the liver is still inevitable.” Therefore, Wu Tao said, The best way to reduce the damage caused by alcohol to the human body is not to drink or to drink less.
Flat shoes are best for the feet
When the cold snap hits, flat snow boots seem to have suddenly become the norm. A beautiful sight on the street. The reason why it is favored by men, women and children is not only because it is warm, but also because of the deep-rooted idea in people\’s minds that wearing flat shoes is the best for their feet. But is this really the case? /p>
Dr. Sun Yang from the Department of Sports Rehabilitation of Beijing Sport University said that compared with high heels, flat shoes can indeed enable the foot to enjoy more optimal stress and are more comfortable and convenient to wear, but they are not suitable for everyone. People. For example, flip-flops and sandals that are common in summer and snow boots worn in winter are all flat shoes, but they are not suitable for people who are born with abnormal stress on their feet (such as ankle valgus and flat feet). Wearing flat shoes with soles that are too thin, too soft, and with too low heel support
For some special groups, such as those with existing foot deformities, diabetics, the elderly, and flat feet, it is best to consult a professional. For a foot orthotist, a pair of orthopedic insoles may be more suitable to balance the force on the sole of the foot and thereby reduce pain caused by force.
There are many homemade facial masks that can beautify the skin.
Fashionable women like to use fruits on their faces, saying that fruits contain fruit acids, which are helpful for beauty and skin care, such as removing freckles, whitening, and anti-wrinkle, etc. But in fact, the nutritional value of vegetables and fruits mainly comes from the blood vessels after being digested by gastric acid. Deliver nutrients to the body, and our skin has a barrier function that makes it difficult for such water-soluble things to be absorbed when applied to the face, let alone have any nutritional value. Deputy Chief Physician of the Department of Dermatology, Peking Union Medical College Hospital He Zhixin analyzed that.
The reason why many skin care products containing fruit acids can improve some skin indicators, such as exfoliation, is generally believed to be related to the small molecules of fruit acids. It penetrates the skin and seizes the calcium between keratinocytes, which will break the connections between cells and accelerate the shedding of keratinocytes, thus achieving the purpose of \”exfoliation\”. \”The ingredients of homemade facial masks are very natural and have not been processed by some science and technology. The molecules are too big to achieve such an effect,\” said He Zhixin.
If you have to look for \”small molecular fruit acids\” to make facial masks in your life, it is not impossible, such as sugar cane and yogurt. The glycolic acid and lactic acid contained in it are much smaller than the fruit acid molecules in fruits.
But the content of these \”natural sources\” of fruit acid is not that high – just apply yogurt directly on your face to get lactic acid. The content is only about 5%. Even if it is \”effective\” for ladies to apply it on their face, it has a limited effect. It is basically a placebo, and it is only good for improving mood and entertainment.
