高温席卷多地 专家提示做好健康防护

Core Viewpoint - The article highlights the ongoing high-temperature weather affecting various regions in China, with experts advising on health protection measures during this period [1][2]. Group 1: Weather Forecast and Impact - From July 14 to 22, regions including central and southern North China, Huanghuai, Jianghan, and central Shaanxi are expected to experience sustained high temperatures, with local maximum temperatures potentially reaching or exceeding historical records [1]. - Data indicates that since July, areas such as Huanghuai, Jianghuai, Jianghan, and Jiangnan have recorded high temperatures ranging from 37°C to 39°C, with some locations reaching 40°C to 41°C, and continuous high-temperature days lasting from 5 to 8 days [1]. - The main weather systems causing this heat wave are the stable subtropical high and continental high, leading to significant adiabatic warming and enhanced solar radiation, resulting in persistent high temperatures [1]. Group 2: Health Risks and Recommendations - High temperatures can disrupt the human body's temperature regulation system, potentially leading to heatstroke, especially in conditions of low wind speed and high humidity [2]. - When temperatures exceed 32°C with humidity over 70%, the body's perceived temperature can rise by 10°C, increasing the risk of heat-related illnesses [2]. - Public health recommendations include avoiding prolonged outdoor activities during high-temperature periods, implementing effective sun protection measures for outdoor workers, and ensuring adequate hydration [2].
