Core Viewpoint - The article highlights the increasing health risks associated with high temperatures, particularly focusing on heat stroke and cold-induced heat illness, and emphasizes the importance of preventive measures and timely medical intervention [1][2][5]. Group 1: Heat Stroke - Heat stroke is characterized by a core body temperature exceeding 42°C, leading to significant organ dysfunction and potential death [2]. - The condition arises when the body's temperature regulation fails, causing cellular energy metabolism disruption, particularly affecting vital organs like the heart, liver, and kidneys [2][3]. - Preventive measures include regular hydration of 200-300 milliliters per hour, balanced nutrition, and avoiding outdoor activities during peak heat hours [3][4]. Group 2: Cold-Induced Heat Illness - Cold-induced heat illness occurs when individuals transition from a cold environment to a hot one, causing symptoms like dizziness and nausea due to rapid temperature changes [5][6]. - To prevent this condition, it is advised to gradually adjust to temperature changes, maintain a maximum temperature difference of 5°C between indoor and outdoor environments, and ensure adequate hydration [7][8]. - Symptoms of cold-induced heat illness can be alleviated by loosening clothing, ensuring ventilation, and consuming small amounts of warm water [7][8].
