Why is cold weather easy to induce various diseases?

Winter has become a hotbed of many diseases. The main reasons are cold and dry. In addition, many people have the habit of "cat winter". In winter, indoor ventilation is poor, and air humidity is difficult to control, which leads to poor metabolism and blood circulation and is easy to induce various diseases. First, the high-risk groups of cardiovascular diseases represented by angina pectoris and myocardial infarction: the elderly, hypertension, hyperlipidemia, diabetes, obesity, lack of exercise and people with family history of cardiovascular diseases. Precautionary suggestions: the temperature difference in winter is large, blood vessels are easy to contract and spasm, and dryness is also easy to cause blood viscosity and induce coronary heart disease. Pay attention to keep warm and avoid excessive contraction of blood vessels; Replenish water, not less than 2000 ml per day, to reduce blood viscosity; Avoid eating cold food; Reduce morning exercises; Maintain emotional stability. Second, the high-risk groups of cerebrovascular disease represented by stroke: the elderly, hypertension, hyperlipidemia and people with family history of cerebrovascular disease. Precautionary suggestion: In winter, the contraction of human capillaries and the increase of peripheral resistance of blood circulation will lead to the increase of blood pressure and promote thrombosis, and the elderly are more likely to induce stroke. Pay attention to keep warm, and people with a medical history must pay attention to taking medicine on time; Diet should be light and eat more fresh fruits; Maintain emotional stability. Third: the high-risk groups of respiratory diseases represented by colds, chronic bronchitis and asthma: all people, especially sub-health people. Precautionary suggestion: You can prepare some acupoint stickers and stick them on the corresponding acupoints when you feel the initial symptoms of a cold such as dry throat and itchy throat. Acupoints that are more effective in preventing respiratory diseases are Dazhui, Fengchi, Zhongshan, Tiantu and Shu Fei. Adult acupoint application lasts for 6-8 hours. During the application period, avoid eating cold, greasy, spicy and other irritating foods. Asthma patients should pay attention to avoid cold air. Fourth, the high-risk group of skin diseases represented by itching: people with dry skin. Precautionary suggestion: In winter, due to the lack of oil on the skin surface, the skin resistance decreases, which is very prone to skin itching. Don't bathe too often, don't use alkaline shower gel, and be sure to use skin cream after bathing; For people with dry skin, you can put some cooked oats or starch in the bathtub when taking a bath at home, which can nourish the skin. Don't pinch people blindly in the first aid of cardiovascular and cerebrovascular diseases. If the family members suddenly have symptoms of cardiovascular disease, they should immediately call the emergency number, at the same time, let the patient lie flat, immediately give the patient nitroglycerin, and try to give the patient oxygen with simple oxygen inhalation devices such as "Oxygen Lide". Family members should try to stay calm, don't cry, and keep quiet indoors, so as not to stimulate patients to aggravate their illness. The sudden attack of cerebrovascular disease is easy to cause coma, and the symptoms are aggravated headache, drooling and sometimes half a face is numb. If the patient is in a coma, the family members must first call the emergency number, and then let the patient stay in the lateral position, clean up the patient's vomit in time, and keep the respiratory tract unblocked. Don't shout or shake the unconscious person violently in order to wake up the patient, which will only worsen the condition quickly. Don't pinch the patient blindly, which may hinder the patient's breathing and lead to dyspnea.
