What disease can you get if you are in a cold state for a long time? Please, great gods.

Although most colds are caused by viruses, catching cold and catching cold are the main reasons. Experts believe that the decline of lung function caused by cold is an important factor leading to winter colds. Through various room temperature tests, it is proved that lung function will be obviously hindered when the room temperature is low. This will give the cold virus a chance to invade the lungs and cause a cold attack. When the cold wave strikes, patients with emphysema and tracheitis are most likely to get worse. This is because cold air will reduce the local temperature of respiratory tract, make capillaries contract and reduce blood. Coupled with the cold, the ciliary activity of mucosal epithelium slows down, which weakens the function of trachea to expel bacteria into respiratory tract. If viruses or bacteria invade at this time, bronchitis will recur. Cold stimulation can cause dysfunction of cerebral cortex, which has an important relationship with the onset of ulcer disease. Vagal reflex of stomach can make gastric acid secrete too much. At the same time, the excitability of sympathetic nerve is enhanced, the vascular spasm of gastric and duodenal mucosa is greatly weakened, and the gastric and duodenal mucosa is eroded by acidic digestive juice to form ulcers. Due to the decrease of air temperature and the increase of air pressure, the function of sympathetic nerve and parasympathetic nerve can be disordered, causing capillary contraction and capillary resistance to increase. This is extremely unfavorable for circulatory diseases such as coronary heart disease, cerebrovascular disease and hypertension. Cold makes blood vessels contract, blood pressure rises, capillaries may harden, and even arterioles continue to spasm, which is related to cerebral hemorrhage and cerebral embolism. According to research, about 77% patients with myocardial infarction and 54% patients with coronary heart disease are more sensitive to weather changes. Due to the stimulation of cold, human blood vessels contract, the peripheral resistance increases, the average arterial pressure increases, and the myocardial aerobic index also increases accordingly, which leads to the aggravation of myocardial hypoxia. In addition, cold can also change the physical and chemical properties of blood, such as accelerating erythrocyte sedimentation rate, shortening coagulation time and increasing blood viscosity. These are the main causes of arterial thrombosis, so the mortality rate of patients with myocardial infarction and coronary atherosclerosis is higher in winter. Cold hands and feet: Women are more afraid of cold than men in winter, especially their hands and feet. Even if they wear gloves and cotton socks, their teeth will tremble with cold. Traditional Chinese medicine believes that people are afraid of cold because "the human body is weak in yang and lack of qi and blood, and it is impossible to warm muscles to resist the invasion of external cold pathogens." Women have yang deficiency constitution and poor tolerance to cold. Scientific research also found that "sensors" in women's skin are more sensitive than men's. After receiving the "cold" information, the brain will immediately order the metabolic system to speed up its work, so that the blood circulation system will retreat to the second line of defense, that is, from the skin, limbs to the trunk. This is the main reason why many women feel cold hands and feet when the temperature is low. Exercise is the best way to deal with cold hands and feet. Eat more warm and blood-activating foods, and do more warm-up exercises such as stretching your fingers, winding your arms and twisting your toes. Avoid staying still for a long time, especially sitting in front of the computer all day. Pay attention not to smoke at ordinary times, and avoid taking too much caffeine food, such as coffee, strong tea, cola, etc. Dry skin: The skin is a very sensitive organ. In the coming days of winter, the blood vessels of the skin often contract, and the secretion of sweat glands and sebaceous glands is obviously reduced. Some people will have itchy skin, redness and swelling, and even irregular chapping and peeling in severe cases. This phenomenon is most obvious in the lower limbs. Among them, it has something to do with the way you take a shower. Some people are afraid that they are not clean. They are used to washing repeatedly with shower gel and hot water like summer, and the oil on the skin surface is washed repeatedly, and the dry skin is getting more and more serious. So pay attention to the composition and frequency of bathing. Don't take a bath too often, once a day is enough. Moreover, it is best not to bathe with soap (because soap is generally alkaline, which is easy to unbalance the PH value of the skin surface), and the water temperature should not be too high. Try to use a bath lotion containing moisturizing ingredients, and apply a moisturizing cream containing moisturizing ingredients after bathing, such as vaseline. A dull pain in the stomach: Winter is the season of high incidence of stomach diseases. For example, gastritis is inflammation of gastric mucosa, which is divided into acute and chronic. Most acute gastritis has a sudden onset and obvious clinical symptoms. Chronic gastritis is a common chronic disease of digestive system. Most of them are dull pain in the upper abdomen, bloating, belching, acid regurgitation, similar to ulcer disease, and some patients may also be complicated with upper gastrointestinal bleeding. Protecting the stomach starts with eating. Eating is a very important thing in our life. Eat three meals regularly, chew slowly, pay attention to hygiene, be careful and clear, and quit smoking and drinking. Chronic atrophic gastritis should eat some foods that can stimulate gastric acid secretion, such as thick soup, fish soup, soup and so on. Don't eat food that excessively stimulates gastric acid secretion. You should eat some fresh vegetables, milk, eggs and so on. Don't eat fried and irritating foods, such as peppers, leeks and salty foods. Infectious diseases in winter: common infectious diseases in winter include influenza, rubella and measles, followed by rare but more deadly epidemic cerebrospinal meningitis, mumps and hemorrhagic fever, all of which are related to the stimulation of dry and cold air on respiratory tract. Climate change is the first test of human immunity. If you don't pay attention to exercise at ordinary times and the closed indoor air doesn't circulate with the outside world often, then diseases are likely to patronize frequently. Don't put on thick clothes just because you are afraid of cold, and don't stay in an air-conditioned room all day to enjoy the warmth of air conditioning. The best way is to get yourself moving, because exercise can not only promote the blood circulation of the body and enhance the cardiopulmonary function, but also be very beneficial to our respiratory system. If you love sports, you will soon find that you can go out without dressing up as a ball. Of course, in the season of high incidence of influenza, influenza vaccination is also a necessary guarantee for health. Cough and runny nose: When the weather turns cold, it will first test our respiratory system. Chronic bronchitis, chronic obstructive pulmonary disease, emphysema, cor pulmonale and other respiratory diseases will have symptoms such as cough, expectoration and runny nose, so you should take medicine in time under the guidance of a doctor. Severe respiratory diseases are sensitive to the living environment. For example, if the smoke from smoking fills the room for a long time, the cough will get worse. Among many meteorological and environmental factors, air humidity has the greatest influence on respiratory diseases. Because the research results and clinical practice prove that only indoor air humidity reaches 55%-65%, which is more conducive to the treatment and rehabilitation of various respiratory diseases. Patients themselves should absolutely ban smoking and reduce the chance of passive smoking. Live regularly and avoid fatigue, staying up late or being overly nervous. Pay attention to the window ventilation of the room and keep the indoor air circulating. We should also take part in light physical labor or outdoor activities, such as walking, jogging and breathing exercises. Exercise should be gradual, from slow to fast, and gradually increase the amount of exercise. Seasonal melancholy: seasonal changes will affect people's mood. Especially in winter, when the temperature is cold and there is little sunshine, the natural biological clock in the human body will also change, and the natural rhythm of human biology and physiology may be disordered in a short time, which will lead to physical discomfort. Loss of appetite, weight loss, gastrointestinal discomfort and constipation are its early symptoms. In addition, it may be accompanied by depression, inattention, easy drowsiness, poor sleep quality, endocrine disorders, and lack of motivation, resulting in the whole spirit being depressed. The way to deal with it is to take more physical exercise; Indoor windows are often ventilated to keep sunny to increase excitement; Appropriate intake of high-calorie foods, as well as coarse grains rich in fiber such as bread; In the bleak winter, let yourself get more sunshine. Sunlight can not only dry depression, but also help people synthesize vitamin D in the body with the help of sunlight, which is also good for calcium supplementation. Joint pain: Cold can cause joint pain. Osteoarthropathy mainly invades the joints of limbs and trunk spine. A series of symptoms and signs may appear clinically, including joint pain, swelling, deformity and dysfunction. Every attack of the disease often has certain incentives, such as fatigue, increased activity, catching cold and so on. After treatment, the symptoms and signs will be relieved. From a certain point of view, disease is not a disease, but a physical degradation and aging. To prevent joint pain, the first thing is to keep warm. Cold weather will make blood flow to important organs, joints and other parts of the human body too much, and there is not enough blood to keep warm. Therefore, when the weather is cold, we should pay attention to keep indoors dry, keep warm when engaging in outdoor activities, and increase or decrease clothes according to the weather conditions. Pay attention to diet and take enough protein, such as milk, soybeans and other foods. Pay attention to rest and exercise properly. Taking a hot bath or soaking in a hot bath helps to relieve joint muscle stiffness. Gout attack: Gout often attacks on cold nights. This is a long-standing disease, known as the "disease of wealth." With the increasing proportion of various animal foods in the diet structure, the incidence of gout is also increasing. It is easy to induce in middle-aged and elderly people and patients with chronic cardiovascular diseases. At present, gout has become a common "civilized disease" of modern people. The onset age of gout is generally between 30 and 70 years old, and most of them are men (95%), and the ratio of male to female is 20∶ 1. It is a kind of "son preference" disease, which is more common in mental workers, meat eaters, alcoholics and obese people. To deal with gout, we should control our diet and avoid eating a lot of high-purity seafood such as sardines, carp, eels, shrimps, crabs, oysters and scallops, such as fish skin and animal viscera (liver, kidney, intestine, heart, etc.). ) and vegetables such as lentils, dried seaweed, dried mushrooms and spinach. In addition, alcohol, especially beer, must be banned; Drink plenty of water; Maintain a normal standard weight. Nosebleeds: Nosebleeds are most likely to occur in winter, which is also because when the climate is dry and cold, the nasal mucosa becomes dry and fragile, and it is easy to be injured, leading to the rupture of small blood vessels. If you are a person with high blood pressure, nosebleeds are more urgent. In particular, some antihypertensive drugs will dilate peripheral blood vessels, causing considerable bleeding. For minor bleeding, the patient can be placed in a semi-sitting position or lateral position, with his head slightly lowered forward, breathing through his mouth to keep the airway unobstructed, and pressing his nose with his fingers to stop bleeding. After about 10 minutes, the bleeding volume will naturally decrease or stop. Massive or rapid bleeding, especially complicated with hypertension or other diseases, often requires emergency medical assistance. Usually, you need to drink plenty of water to keep the indoor air circulating. If conditions permit, you can use air heating to create a humid environment for yourself and give your body some time to adapt to the dry and cold air when the seasons change.
