Core Viewpoint - The article highlights the increasing incidence of thunderstorm asthma, particularly after heavy rain, and emphasizes the need for public awareness and preventive measures against this health risk [1]. Group 1: High-Risk Groups - Individuals with a history of thunderstorm asthma are at higher risk [4]. - Those diagnosed with asthma and have known allergies to pollen or mold are also vulnerable [4]. - People with pollen allergies or a family history of allergic diseases should be cautious [5]. - Even individuals without a prior asthma diagnosis may experience thunderstorm asthma, indicating a broader risk [5]. Group 2: Warning Signals - Meteorological warnings indicate that the 6-24 hours before a thunderstorm is a high-risk period due to rising pollen levels [7]. - Physical warning signs include nasal congestion, runny nose, and itchy eyes, which can escalate to wheezing and chest tightness [8]. - Environmental cues such as a musty smell after rain may signal a spike in mold spores [8]. - A collective outbreak can be suspected if multiple individuals in the same area exhibit respiratory symptoms [8]. - Air quality monitoring showing a spike in PM2.5 and allergen levels serves as an additional warning [8]. Group 3: Preventive Measures - It is crucial for high-risk individuals to check weather forecasts, especially regarding air quality and pollen levels during the autumn thunderstorm season [10]. - During thunderstorms, it is advisable to stay indoors and wear N95 masks or pollen-blocking masks when going outside [10]. - Regular cleaning to reduce indoor allergens like dust mites and mold, along with using air purifiers, is recommended [10]. Group 4: Emergency Response - Recognizing symptoms such as wheezing, chest tightness, and dry cough is essential for quick response during an asthma attack [11]. - Adjusting body position to a sitting or slightly forward-leaning posture can aid breathing [11]. - Asthma patients should follow medical advice regarding medication and keep emergency inhalers readily available [11]. - Maintaining calmness and seeking immediate medical attention if symptoms worsen or if there is confusion or severe breathing difficulty is critical [13].
