As the saying goes: “Cold dew feet do not show.” Before and after the cold dew season to focus on foot warmth, sandals can basically put away, to prevent “cold from the foot”. As the two feet are farthest from the heart, the blood supply is less, and because the fat layer of the feet is thin, especially vulnerable to the stimulation of cold. The feet are cold, easy to cause the upper whistle mucous membrane capillary constriction, resulting in a decrease in body resistance. The inhalation tract is extremely sensitive to cold air stimulation, sudden cooling makes the inhalation organs resistance drop, the disease will take advantage of the evil. Light is caused by external cough, heavy can make bronchitis, asthma and other whistling system disease attacks. If conditions allow, it is best to use hot water to soak your feet before traveling in the cold dew season. Soak feet with hot water can prevent respiratory infections, but also make the blood vessels expand, blood flow accelerated, improve the skin of the feet and tissue nutrition, reduce the occurrence of lower limb pain, so that people are energetic. The cold air of the cold dew period can lead to many diseases. One of the most common is the whistling tract diseases. The inhalation tract is most sensitive to cold air stimulation, sudden cooling of the resistance of the inhalation organs to decline, the disease evil to take advantage of the vain. The lighter the cough, the heavier the bronchitis or bronchial asthma and asthmatic bronchitis attacks. In addition, people with a history of stomach problems often have attacks at this time, causing gastric perforation or gastric bleeding. As for rheumatism and arthritis patients, they are more vulnerable to climate change. 1, acute gastroenteritis. After autumn, the body’s digestive function gradually declines, the intestinal tract resistance to disease is also relatively weakened. If you continue to eat a lot of raw melon fruit, or directly consume drinks and food taken from the refrigerator, diarrhea, dysentery and other acute and chronic gastrointestinal diseases may occur. Eat as little food as possible that is easily inflammable, with a light diet structure; when eating seafood and barbecue, be sure to pay attention to freshness. When cooking, be sure to add ginger and wine to dispel the cold and detoxify; autumn should be careful to eat melon fruits, the spleen and stomach cold should be especially contraindicated. 2, cardiovascular disease. Autumn is the transition season from summer to winter, cold and warm changeable, often not easy to immediately perceive. Autumn’s cold and warm are often repeated, cold and warm, warm and cold again, people can’t guard against. At this time of year, the incidence of myocardial infarction is significantly higher, and hypertensive patients in the autumn and winter, blood pressure is often 20 mm Hg higher than the summer blood pressure, easily causing cardiovascular and cerebrovascular blood circulation disorders. Therefore, the prevention of autumn colds and cold is quite important for patients with cardiovascular and cerebrovascular disease. 3, gout. The weather turns cold in late autumn, the human food center is stimulated by the cold, causing an increase in appetite, meal volume, if more fat, sweet and thick taste, the body produces too much blood uric acid, prone to gout. In the current season, you should drink more water to promote the discharge of uric acid and prevent the formation of stones. To prevent the concentration of urine at night, you can increase the amount of water you drink in the middle of the night before going to bed. The first thing you need to do is to take care of your health by eating more yams, radishes and other “root” vegetables. Yam is not only a Chinese medicine, but also a delicacy, a familiar tonic. Research has proven that the content of B vitamins in yam is several times that of rice, and the minerals are extremely rich in potassium. In addition, yam has a complementary effect on diabetes. In addition to the ease of satiety, which is good for controlling food intake, mannoprotein has the effect of improving glucose metabolism and insulin sensitivity. Because of the high starch content of yams, it is best to replace some of the staple foods with yams when consuming them, that is, to reduce the amount of staple foods, especially for diabetics, to avoid the problem of excess energy. In addition to “root” vegetables, persimmons are also good for eating in autumn. Persimmons are rich in sucrose, glucose, fructose, protein, carotene, vitamin C and other nutrients, and have the functions of clearing heat and dryness, moistening the lungs and resolving phlegm, softening the hardness, generating fluid and quenching thirst, strengthening the spleen, treating dysentery and stopping bleeding. Persimmon is rich in pectin, which is a water-soluble dietary fiber with laxative effect, and is good for correcting constipation and maintaining the growth of normal intestinal flora. It can also relieve dry cough, sore throat and high blood pressure. Therefore, persimmon is a natural health food for patients with chronic bronchitis, hypertension, arteriosclerosis, and internal and external hemorrhoids. Fresh persimmons are also high in iodine. However, because persimmons contain more tannic acid and pectin, they form hard lumps of different sizes under the action of gastric acid in fasting conditions, and if these lumps cannot reach the small intestine through the pylorus, they will remain in the stomach and form persimmon stones. If persimmon stones cannot be expelled naturally, they can cause obstruction in the digestive tract, resulting in severe pain in the upper abdomen, vomiting, and even vomiting blood. Therefore, although persimmons are good, they should not be eaten in excess.
