Core Viewpoint - The article highlights the rising risk of "heat stroke" during extreme high temperatures, particularly when temperatures exceed 32 degrees Celsius, and distinguishes it from regular heat exhaustion [1][3]. Group 1: Mechanism and Symptoms - Extreme high temperatures can increase the risk of cerebrovascular diseases, with most "heat strokes" classified as ischemic strokes [3]. - High temperatures lead to changes in blood pressure and blood volume, which can result in blood clot formation due to dehydration and blood concentration [4][6]. - Symptoms of "heat stroke" include dizziness, headache, nausea, and vomiting, which can be confused with heat exhaustion [11][15]. Group 2: Differentiation from Heat Exhaustion - Heat exhaustion is characterized by a disruption in temperature regulation, with symptoms like flushed skin, dizziness, and high fever, but lacks specific neurological deficits [13]. - In contrast, "heat stroke" involves sudden neurological deficits such as paralysis, numbness, speech difficulties, and unsteady gait [15]. Group 3: Prevention and Management - Experts recommend managing emotions and maintaining a calm mindset to avoid blood pressure fluctuations during high temperatures [20]. - It is advised to avoid outdoor activities during peak heat hours and to keep indoor temperatures between 25-28 degrees Celsius while ensuring proper hydration [23].
