在華人地區成長的我們,從小就被教育要「喝溫熱開水 不要喝冰的」,那麼運動的情況下也是這樣嗎?
分享運動營養知識的粉專「運動營養團隊」指出,過去曾經有許多馬拉松中暑的案例,嚴重甚至有人被活活熱死。
我們平時正常的體溫大約為 37 度,當上升至 38 度時就視為發燒了,可見體溫的恆定是多麼的重要。
運動無可避免會使我們的核心溫度上升,若在過程中飲用冰水(4℃)相較於溫水(22℃),可以延緩核心溫度的上升,也能減少皮膚表面出汗的速率。
所以當你下次運動時,要記得裝冰開水哦,溫水就留給平常的時候喝吧。
運動營養團隊補充,還是要針對每個人的運動時間及強度,在寒冷天氣從事強度很高或像馬拉松這種長時間運動,喝冰水還是有幫助的,若只是慢跑或強度較低的運動當然溫開水也是可以的,還是要依照個人的感受為主。
