I have the impression that it is the elderly who get asthma, but nowadays it is different, the incidence of children and adolescents is increasing year by year. Recently, the incidence of asthma in children has been on the rise in recent years. In addition to a possible family history of the disease, the rapid urbanization process has led to a large increase in allergens that trigger asthma, such as car exhaust, preservatives and cosmetics. In addition, residents also “harbor” a large number of asthma “killers” – dust mites in their homes. “Many dust mites are hidden in the hair of dogs and cats, carpets, curtains, and even air conditioning filters have become a large number of dust mite hiding places.” Therefore, if there are asthma patients at home, the air conditioning filter should be cleaned 1 time a week. Moreover, 35% – 40% of chronic coughs are actually asthma. In addition, episodes of coughing, especially at night and in the early hours of the morning, are likely to be asthma, but are easily thought of as bronchitis. Increased mental stress is also a major reason for the current increase in asthma patients. To prevent asthma in winter, first of all, avoid contact with allergens as much as possible, and also use desensitization therapy; allergic asthma patients should not be exposed to irritants such as fur, and a few patients are also allergic to certain foods, and common asthma-inducing foods include wheat, eggs, milk, seafood, etc.; diet, eat more fruits and vegetables, as well as deep-sea fish rich in fatty acids, such as salmon, tuna, sardines, etc.; eat more Nuts, such as walnuts and peanuts; in life, pay attention not to be suddenly exposed to cold air, prevent upper respiratory tract infection, pay attention to neck warmth; control weight; do not smoke second-hand smoke. Here, asthma treatment experts remind patients that the treatment of pediatric asthma must go to a regular professional hospital, not to blindly seek medical advice and take drugs, so as not to delay the disease, you have any questions can give me a message, I will promptly reply.
