Bronchial asthma is a serious global health problem, a chronic airway disease that can affect people of all ages and countries and can be fatal in severe cases. Bronchial asthma is the result of chronic inflammation that leads to airway hyperresponsiveness, which can cause recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing that are especially exacerbated at night and in the early morning. These episodes of symptoms are usually associated with widespread variable airflow obstruction in the lungs, which usually resolves spontaneously or with treatment. It is now the hot summer season and the season of high incidence of bronchial asthma, so what causes summer to be the season of high incidence of asthma? This involves the triggers of bronchial asthma, which commonly include: climatic factors, exercise and hyperventilation, geographic factors, excessive emotional changes and mental factors. The main factor of asthma in summer is “cold air”, which can lead to heat loss in the airways, causing mast cells to release mediators, directly or indirectly inducing inflammation in the airways, causing bronchospasm and acute asthma attacks. In addition, the air in the air-conditioned room can not be renewed in a timely manner, the air conditioner memory accumulation of viruses, dust and mites is also the cause of asthma. So, how should bronchial asthma patients deal with summer asthma? 1, asthma patients should try to avoid too large a temperature difference between hot and cold, especially in the use of air conditioning indoor and outdoor temperature difference should not exceed 5 ℃, if you can not control the temperature difference, then, from the hot outdoors do not immediately enter into the cold indoors, there should be a moderate buffer, so that the environment in the airway as much as possible to adapt; in addition, do not face the air conditioning vent, so that you can avoid air-conditioning accumulation of allergens such as dust A large number of one-time inhalation of airways; 2, to avoid eating too cold food and drink; 3, to improve their physical fitness, you can carry out the appropriate intensity of aerobic exercise, enhance physical fitness; 4, is the standardized drug treatment. Although the incidence of bronchial asthma is high and can lead to death in severe cases, it is still a preventable and treatable disease. Avoiding allergens and regular and standardized treatment can greatly reduce the frequency of acute asthma attacks. Therefore, scientific disease management will bring asthma patients a peaceful summer!
