科普｜气温突破33℃就应警惕“热中风”！

Core Insights - The article highlights the increased risk of cerebrovascular diseases during both cold and hot seasons, emphasizing that high temperatures can also trigger conditions like ischemic stroke, particularly when temperatures exceed 33°C [1][3] Group 1: Health Risks - A significant rise in the incidence of cerebrovascular diseases is observed when temperatures surpass 33°C, with ischemic stroke being particularly prominent [1] - The risk of cardiovascular diseases is exacerbated by the temperature difference between air-conditioned environments and outdoor heat, especially when the difference exceeds 7°C [3] - High temperatures can lead to dehydration, reducing blood volume and increasing blood viscosity, which heightens the risk of stroke [3] Group 2: Vulnerable Populations - High-risk groups for stroke include individuals with pre-existing cerebrovascular conditions, the elderly with vascular hardening, and younger individuals with unhealthy lifestyles [3][4] - The article stresses the importance of recognizing risk factors for stroke prevention, including maintaining hydration and avoiding extreme temperature fluctuations [4] Group 3: Emergency Response - Immediate action is crucial when a stroke occurs, including moving the individual away from extreme temperatures and ensuring clear breathing [4] - The critical window for treatment is between 4.5 to 6 hours post-stroke onset, where timely interventions can significantly reduce disability rates [4]
