Asthma attacks are often seasonal, with more attacks in spring and autumn. It is important to prevent asthma attacks and daily prevention. 1. Pay attention to keep warm Avoid cold and flu as well as cold air stimulation to trigger asthma. 2.Avoid contact with allergens For those who are allergic to pollen and plants, please do not go to gardens and botanical gardens; for those who are severely allergic to pollen, consider off-site prevention. Also, during the day, the concentration of pollen in the air is higher in the midday and late afternoon, so go out as little as possible at this time. In areas with high sand and wind, when traveling, pay attention to the weather conditions and go out less when it is windy to avoid the stimulation of dust and cold air. Asthma patients should pay special attention to indoor cleanliness and air circulation, because dust and bacteria in the air are the main allergens that cause asthma attacks. 4, quit smoking The chemicals in cigarettes and the smoke emitted when smoking can have a direct impact on asthma patients because they can stimulate the respiratory ducts, so patients should quit smoking and, do not stay in smoking groups for a long time to prevent the inhalation of second-hand smoke. 5, moderate exercise Some asthma patients have concerns about exercise, they stop all exercise, in fact, as long as they can choose the right exercise according to their own situation can not only effectively enhance cardiorespiratory function, but also greatly help to control the disease. 6, year-round prevention of asthma attacks winter to spring, the weather becomes warmer, a lot of pollen particles or bacteria suspended in the air, people with allergies inhale these will begin to sneeze, runny nose, nasal itching, cough, and then gradually cause asthma. Therefore, asthma patients are especially reminded to prevent relapses early. Summer is also the season of asthma, we should pay attention to the “cold” factor attack in the heat, as the weather becomes hot, the use of air conditioners, cold drinks, will inadvertently make asthma patients encounter the cold factor attack. It has been found that once asthma patients encounter cold air, cold wind or consume cold drinks or frozen food, they will be prompted to have an asthma attack. The respiratory system of asthma patients is extremely sensitive, and the sudden attack of cold air will cause the trachea and bronchial tubes, which are already in a highly reactive state, to spasm reflexively, causing coughing and shortness of breath. In addition, the air in the air-conditioned room cannot be updated in time, and the virus and dust accumulated in the air conditioner can also trigger asthma. In autumn and winter, with the dry climate on the one hand and the intensification of cold air on the other, asthma patients need to pay more attention to avoid catching cold and causing asthma attacks. 7.Summarize the causes of the attack After an asthma attack, you should carefully search and analyze the triggering factors and avoid them as much as possible.
