Core Viewpoint - The article emphasizes the health risks associated with thunderstorms, highlighting the need for scientific protection and tailored strategies for different populations to mitigate these risks [1][2][3]. Health Risks of Thunderstorm Weather - Thunderstorm weather poses multi-layered health risks, including direct dangers such as lightning strikes, with global statistics indicating 24,000 to 30,000 deaths and 240,000 to 300,000 injuries annually due to lightning [2]. - Thunderstorm asthma has gained attention, where increased humidity before storms causes pollen and mold spores to swell, leading to allergic reactions and asthma exacerbations when struck by lightning [2]. - Sudden changes in atmospheric pressure during thunderstorms can trigger acute cardiovascular events, particularly in the elderly [2]. - Mental health issues may arise, as the sounds and lights of thunderstorms can provoke anxiety in sensitive individuals, and the risk of accidents increases due to slippery conditions [2]. Scientific Protection and Tailored Strategies - Individuals are advised to monitor weather forecasts closely and avoid outdoor activities during thunderstorm warnings, seeking shelter in buildings with lightning protection [3]. - Those with asthma or allergies should close windows and use air purifiers, keeping emergency medications on hand [3]. - Patients reliant on medical devices should ensure power supply and prepare emergency kits for potential device failures [3][4]. Community and Systemic Measures - Establishing a refined management mechanism at the community level is crucial, with health service centers collaborating with property management to monitor high-risk individuals [5]. - Public spaces should enhance standardized protective measures, including lightning warning systems and clear evacuation signage [6]. - Upgrading meteorological services is essential for effective disaster prevention, utilizing AI and big data for precise warning dissemination [6]. - Medical institutions must strengthen emergency response systems, ensuring adequate supplies for treating lightning-related injuries and training staff in basic emergency skills [6]. Conclusion - While thunderstorms are uncontrollable, effective preparation and scientific responses can significantly reduce health risks, necessitating personalized protection plans for individuals [6].
