注意！多地高温出现重症病例，这些因素会加剧“热射病”→

Core Viewpoint - The article highlights the increasing incidence of heat-related illnesses, particularly heat stroke, due to extreme temperatures across various regions in China, emphasizing the severity and potential fatality of heat stroke cases [1][2]. Group 1: Heat Stroke Overview - Heat stroke is classified as a severe heat-related emergency, characterized by a core body temperature exceeding 40°C and central nervous system dysfunction, with a mortality rate ranging from 20% to 50% [1]. - The progression of heat-related illnesses typically starts with premonitory symptoms, followed by mild heat illness, heat exhaustion, and can ultimately lead to heat stroke [1]. Group 2: Types and Risk Factors - Heat stroke can be categorized into "classic heat stroke" (CHS) and "exertional heat stroke" (EHS), with CHS occurring due to passive exposure to high temperatures, often affecting vulnerable populations such as the elderly, children, and those with pre-existing health conditions [2]. - EHS is primarily caused by high-intensity physical activity, commonly seen in healthy young individuals engaged in strenuous activities during summer [2]. - Environmental factors contributing to heat stroke include intense solar radiation, prolonged high temperatures, sudden temperature increases of 5-10°C, and poor ventilation [2]. Group 3: Individual Risk Factors - Individual factors that may exacerbate the risk of heat stroke include underlying health conditions (e.g., hyperthyroidism, schizophrenia), mismatched physical fitness levels, inadequate hydration, and poor sleep quality [2][3]. Group 4: Emergency Response - Immediate response to symptoms such as dizziness, fatigue, and confusion is crucial, with key actions including moving to a cooler environment, removing clothing, and applying cold water to the body while fanning to promote heat dissipation [4].
