Core Viewpoint - The article highlights the severe heatwave affecting multiple regions in China, particularly Guangdong, with unprecedented high temperatures and associated health risks due to heat-related illnesses [1][2][4]. Group 1: Weather Conditions - The Central Meteorological Observatory issued a yellow heat warning on July 8, predicting daytime temperatures in northern and eastern Guangdong to reach 37-39°C [2]. - As of July 8, 142 heat warnings were in effect in Guangdong, including 108 orange and 34 yellow warnings [2]. - The weather forecast indicates that high temperatures will persist with thunderstorms on July 8-9, but rainfall is expected to alleviate the heat by July 10 [4]. Group 2: Health Risks and Incidents - From June 7 to July 6, Shenzhen reported 122 cases of heatstroke requiring emergency assistance, with 78 individuals hospitalized, including 9 in serious condition [9]. - A case study from Guangzhou highlighted a 34-year-old man suffering from heat cramps due to prolonged exposure to high temperatures, requiring urgent medical intervention [11][14]. - Symptoms of heat-related illnesses range from mild (dizziness, headache) to severe (heat cramps, heat exhaustion, heat stroke), with the latter being life-threatening [20][26]. 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].

Core Viewpoint - The article highlights the ongoing extreme heat wave affecting multiple regions in China, with temperatures exceeding 35°C and reaching as high as 40°C in certain areas, prompting health risk warnings and advisories for the public [1][2][4]. Group 1: Heat Wave Impact - The Central Meteorological Observatory issued a yellow warning for high temperatures, predicting daytime highs above 35°C in regions including southern North China, Huanghuai, Jianghuai, Jianghan, and much of Jiangnan [1]. - Specific areas such as the Turpan Basin in Xinjiang, northern Shandong, and central-northern Henan may experience temperatures exceeding 40°C [1]. Group 2: Health Risk Warnings - The National Disease Control and Prevention Bureau, in collaboration with the China Meteorological Administration, has issued continuous high-temperature health risk warnings, advising the public to avoid outdoor activities during peak heat hours and ensure adequate hydration [2]. - The high-temperature health risk warning differs from regular high-temperature warnings by focusing on the potential health impacts of elevated temperatures, categorizing risks into five levels: low, moderate, high, and extremely high [2][4]. Group 3: Symptoms and Emergency Measures - Symptoms of heat-related illnesses include dizziness, thirst, fatigue, and elevated body temperature above 38°C, indicating potential heat stroke [5]. - In cases of severe symptoms such as a body temperature exceeding 40°C, confusion, and rapid heart rate, immediate medical attention is required [7][9].

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]
