〔記者羅碧/台北報導〕入秋別以為就不會中暑!早晚雖開始出現涼意,但「秋老虎」白天仍可能帶來高溫,加上日夜溫差變大,身體調節溫度的負擔反而增加。中醫師提醒,秋天中暑有時並非「熱到受不了」,而是身體在不知不覺間累積過多熱氣;若在高溫環境出現頭暈、頭痛、噁心、全身無力或大量出汗,別再硬撐,應盡快休息、降溫及補充水分。
初鳴堂中醫診所院長周大翔表示,許多人把「中暑」和炎熱盛夏畫上等號,其實只要環境溫度偏高、身體散熱不良,再加上水分補充不足或長時間曝曬,即使已進入秋天,仍可能出現熱不適,甚至發展成中暑。因此,入秋後防暑重點應從單純「防高溫」,轉為更留意身體散熱及水分平衡。

秋老虎期間常見的情況是早上出門覺得涼,中午卻突然變熱,有些人已換上較厚的秋季衣物,身體又得隨著溫度變化不斷調節。若再碰上戶外工作、通勤、運動,或長時間待在通風不良環境,熱氣持續累積又未適時補水,就可能增加身體負擔。
周大翔指出,人體遇到高溫時,會透過流汗、增加皮膚血流等方式散熱,但長時間處於高溫又缺乏水分,散熱機制可能逐漸受到影響。這也是為什麼秋季熱傷害不一定讓人第一時間感覺「熱到受不了」,有時反而先出現頭昏、頭重、疲倦、精神不濟或注意力下降。
不過,頭暈、頭痛等症狀並不能全部直接認定為中暑。若是在炎熱環境中發生,可先離開高溫處,到陰涼、通風環境休息並適度降溫、補充水分;平時也不要等口渴才喝水,應依活動量及飲食方面,周大翔提醒,進入秋季並不代表馬上就要「進補」。秋季氣候逐漸從炎熱轉為乾燥,如果身體仍處於燥熱、疲倦或水分不足狀態,並非補得越多越好,反而應避免過度油膩、辛辣或大量燒烤類食物,可選擇較清爽、含水量較多的食物。
此外,若身體持續不舒服,也要檢視近期是否有睡眠不足、喝水太少、長時間曝曬、工作過度或運動量突然增加等情況,而非全部歸咎於天氣。
周大翔提醒,入秋並不代表高溫立即消失,尤其長時間在戶外工作者、運動族群及年長者,更應注意秋老虎帶來的熱傷害。若離開高溫環境、休息及補水後仍未改善,或不適反覆發作、越來越明顯,就不應自行認定只是中暑,應進一步就醫釐清原因。
