世界各地常常會出現(xiàn)高溫天氣。別以為高溫僅僅讓人們感覺炎熱，實際上它還會引發(fā)疾 病——甚至死亡。每年數(shù)芐萬人死于洪水、風暴、火山噴發(fā)和其他自然災害。極熱天氣也是如此。 專家指出，高溫可能是大自然最致命的殺手。近來，印度有一百多人死于高溫天氣。據(jù)報道，一 天或七天里遭受持續(xù)高溫的襲擊將影響健康。持續(xù)幾天的高溫被稱為熱浪。專家?K，白天的熱浪， 如果到夜晚沒有降溫，:會給身體帶來巨大壓力，這是很危險的。
醫(yī)生說，人們有很多方法保護自己免受高溫的侵害。如果可能的話，盡量避免陽光直射，多 喝涼水。要穿天然材料制作的淺色服裝，不穿合成面料服裝。衣服一定要寬松，以便活動自如。 了解高溫引發(fā)疾病的危險信號，比如頭疼、嘔吐。大多數(shù)人遭受高溫僅會感到肌肉疼痛。疼痛是 一個警告，說明你的身體過熱。醫(yī)生提出，一旦感覺頭疼和肌肉疼痛就應該停止一切活動，在陰 涼地方休息，喝清涼飲料。幾小時內(nèi)都不要進行體力活動，否則還會導致更嚴重的狀況。
醫(yī)生還指出，一些特殊群體在熱浪期間特別危險。他們心臟衰弱、有高血壓或其他心血管病。 炎熱天氣對于那些必須服藥以控制血壓、血流不暢、精神緊張、抑郁的人也是特別危險的。
