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 cold and cold air stimulation induced asthma. 2.Avoid contact with allergens: People who are allergic to pollen and plants should not go to gardens and botanical gardens, and those with severe pollen allergy can consider off-site prevention. Also, during the day, midday and late afternoon are the times when the concentration of pollen in the air is higher, so go out as little as possible. 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. 3.Keep indoor air circulation and place clean: 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, so you should diligently clean and reduce the dust in the air, if in summer, it is not appropriate to open the air conditioner for a long time, you need to replace the fresh air in time. 4, quit smoking: the chemicals in cigarettes and the smoke emitted when smoking will 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, coughing, and gradually cause asthma thereafter. Asthma patients need to be careful to avoid exposure. In summer, the season of asthma is also high, we should pay attention to the “cold” factor attack in the heat, as the weather becomes hot, the use of air conditioning, cold drinks, will inadvertently make asthma patients encounter the cold factor attack. The respiratory system of asthma patients is extremely sensitive, and the sudden attack of cold air will cause the trachea and bronchus, which are already in a high state of reaction, 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, the climate is dry on the one hand, and the cold air intensifies on the other, so asthma patients need to pay more attention to avoid cold-induced asthma. 7.Summarize the causes of the attack: After an asthma attack, you should carefully search for and analyze the triggering factors and avoid them as much as possible. Early, reasonable treatment and efforts to achieve complete control of asthma.
