It is well known that asthma patients are prone to recurrence or exacerbation of their condition when the seasons change, when they are emotional or when the weather changes. In a six-year scientific study conducted by researchers at the Ottawa Health Research Institute in Canada, it was found that there was a 15% increase in hospital visits for asthma during thunderstorms compared to non-thunderstorm days. What are the causes of asthma attacks during thunderstorms? What are the causes of asthma attacks in thunderstorms? 1. Increased concentration of bacterial spores that can trigger asthma attacks Inhalation of allergens is the most common cause of asthma attacks. When a thunderstorm occurs, the concentration of a kind of bacterial spores floating in the air that can make people allergic will increase, which will greatly increase the chance of asthma attacks. 2, thunderstorm fungus, mold reproduction fast Some studies show that the temperature and humidity of thunderstorms are ideal for the reproduction of fungi, mold and other allergens, coupled with the lower air pressure in thunderstorms, the concentration of allergens floating in the air is significantly higher, thus making it easier to more easily trigger asthma. 3, rainy days are suitable for dust mite breeding We all know that, as a very common allergen that induces asthma, dust mites like to hide in some damp corners of the home, such as sofas, curtains, carpets, thunderstorms increase humidity, creating favorable conditions for the reproduction of dust mites, increased dust mites in the air, naturally, also increases the chances of asthma attacks. 4, thunderstorms in the air in the proportion of positive and negative ions change, and more fine particles wind and rain change the strength of the electric field and ion conductivity, so that the proportion of positive and negative ions in the air change. More cations, especially after its combination with dust, more harmful to the human body, such as can cause bronchial smooth muscle contraction, the result triggered by leading to asthma attacks. There are also experts pointed out that lightning can make the air particles differentiation, producing more fine particles more, easy to induce asthma. 5, thunderstorm day patients resistance becomes weak Thunderstorm day weather changes quickly, easy to make people’s resistance becomes weak, easy to trigger asthma due to respiratory tract infection. How to avoid asthma attack in thunderstorm? Asthma patients should try to reduce outdoor activities on thunderstorm days, and should keep windows and doors ventilated when it rains, because the wind and rain at this time can drive allergens away from home. Indoor should be kept clean, pay attention to hygiene corners, home curtains, fabric sofas, quilts, carpets, etc. should be cleaned regularly to prevent dust mites from breeding. The sun should be dried and exposed to the sun in time, if it appears after a thunderstorm. Wear a mask when you go out to prevent allergens.
