Group 3: Prevention and Recommendations - To prevent heat-related illnesses, individuals are advised to avoid outdoor activities during peak heat hours (10 AM to 4 PM), stay hydrated, and monitor vulnerable populations such as the elderly and children [26][27]. - Specific recommendations include moving to shaded areas, hydrating with electrolyte solutions, and using cooling techniques like wet towels or ice packs [28][29]. - The article emphasizes that heatstroke is a serious condition that requires immediate medical attention if symptoms worsen [30].

全国高温健康风险预警连续发布 央视网消息：眼下，今年以来最强高温过程正影响我国多地。中央气象台7月5日早6点继续发布高温黄色预警：预计5日白天，华北南部、 黄淮、江淮、江汉、江南大部、四川东北部、重庆、华南大部以及新疆南疆盆地和准噶尔盆地等地有35℃以上的高温天气。其中，新疆南疆盆 地、河北南部、山东、河南、安徽、江苏、上海、湖北、湖南东部和北部、江西、浙江中西部、福建西北部、重庆、广东北部、广西北部等地 部分地区最高气温37—39℃，新疆吐鲁番盆地、山东北部、河南中北部、浙江西北部、苏皖南部等地局地可达40℃以上。 那么，在高温环境下，我们应如何快速判断自己或他人是否中暑或已经引发热射病了呢？又该采取哪些急救措施？来看医生的解答。 中国医科大学附属第一医院急诊科主任崇巍称："若在高温高湿环境下暴露30分钟以上，出现头晕、口渴、乏力这些先兆症状，伴随体温 升高38℃以上，有皮肤灼热、意识模糊等表现，这就确定已中暑。一旦发现有人中暑，首先要将患者迅速脱离高温、高湿环境，转移至通风阴 凉处。" 中暑症状进一步发展，还可能引发热射病。热射病的典型表现为体温高于40℃、意识模糊、无汗、抽搐、心率过快等。此时应立即将患 ...

Group 1: Weather Impact - A strong heatwave is affecting multiple provinces in China, with high temperatures expected to persist, particularly in Jiangsu, Zhejiang, Fujian, Jiangxi, Hunan, Guangdong, Guangxi, and others [1] - The Central Meteorological Observatory issued a yellow alert for high temperatures, predicting daytime temperatures above 35°C in various regions including North China, Huanghuai, Jianghuai, Jiangnan, and parts of Xinjiang [1][4] - The maximum electricity load in China reached a historical high of 1.465 billion kilowatts on July 4, 2023, an increase of nearly 150 million kilowatts compared to the same period last year [1] Group 2: Meteorological Analysis - The current high temperature and humidity levels are considered unusual for this time of year, with significant heat observed in northern regions before the traditional "Minor Heat" period [2] - The phenomenon is attributed to the early northward movement of the subtropical high-pressure system, which has led to widespread high temperatures and moisture transport from the ocean [2] Group 3: Health Concerns - There has been an increase in cases of heat-related illnesses such as heat stroke, with reports of patients experiencing severe symptoms due to prolonged exposure to high temperatures [5][7] - Recommendations for preventing heat-related illnesses include avoiding outdoor activities during peak heat hours, wearing light clothing, and staying hydrated with electrolyte-rich fluids [8][10]

Core Points - The article discusses the rising temperatures in various regions, with some areas exceeding 40°C, leading to an increased risk of heatstroke [1] Group 1: Heatstroke Symptoms - The progression of heatstroke typically includes premonitory symptoms, mild heatstroke, and severe heatstroke, with heat stroke being the most critical state where the body loses its ability to regulate temperature, leading to multi-organ failure and a mortality rate as high as 70%-80% [2] - Symptoms indicating premonitory heatstroke include dizziness, headache, fatigue, thirst, excessive sweating, palpitations, and lack of concentration [3] - Heat exhaustion may present with symptoms such as excessive sweating, cool and clammy skin, pale complexion, nausea, dizziness, increased heart rate, low blood pressure, and decreased urine output [3] Group 2: Prevention of Heatstroke - It is advised to avoid prolonged exposure to high-temperature and high-humidity environments, taking breaks every 30 minutes when temperatures exceed 32°C or humidity exceeds 60% [4] - Staying hydrated, especially with salt-containing fluids, is crucial [4] - A light diet is recommended, avoiding greasy and spicy foods, as well as alcohol and smoking, which can increase susceptibility to heatstroke [4] - Consuming cooling beverages and seasonal fruits, such as mung bean soup, green tea, and watermelon, is beneficial [4] Group 3: Handling Heatstroke Symptoms - Patients should be moved to a cool, ventilated area, and their clothing loosened to aid cooling [5] - Environmental temperature should be lowered using fans or air conditioning [5] - If the patient is conscious, encourage them to drink fluids, preferably those containing salt [5] - In cases of severe symptoms like unconsciousness or respiratory failure, immediate medical assistance should be sought [5][8] Group 4: When to Seek Medical Attention - Persistent high body temperature exceeding 40°C warrants medical attention [6] - Continuous headaches and muscle spasms are also indicators for seeking help [6][7] - Symptoms such as confusion, extreme weakness, and loss of consciousness require immediate medical intervention [8] Group 5: Incorrect Handling Methods - Rapidly moving a heatstroke patient to an excessively cold environment is not advisable; a suitable temperature range is 22°C to 25°C [9] - Using very cold water for cooling can cause blood vessel constriction, hindering heat dissipation [10] - Self-medication with antipyretics is not recommended as they are ineffective in cases of heatstroke [11]
