冚被次序保暖｜氣溫下降天氣變得寒冷，相信大家都紛紛出動厚被。原來蓋被次序都有學問！即使有厚重的被亦未必能保證溫暖，事關蓋被的先後次序相當重要。早前就有日本節目指出，蓋被先後次序錯誤的話，溫度可相差足足攝氏4度。
保暖蓋被正確法丨蓋被次序測試
日本節目《教えてもらう前と後》列出了三種蓋被方法，分別是(A)先羽絨被後毛毯、(B)先毛毯後羽絨被及(C)先將毛毯鋪在床上，毛毯墊在身下再蓋羽絨被。經過測試後，節目組發現(C)比(B)高4度。
專家就解釋，毛毯鋪在床上能減少體溫流失。而羽絨被由羽毛組成，羽毛需靠體溫膨脹而達到保暖作用，故越貼近身體越保溫。
如果想更加暖，就可以在(C)的基礎上，在被子上方再疊加一張毛毯，因為毛毯能夠鎖住被子帶來的熱能。
結果發現，第3種方法更暖，被內的溫度高4℃！記得先將毛毯墊在床上，然後整個人睡在毛毯上，再會更保暖。若想再加暖，在第3種方式的基礎上，於被的上方疊一張薄毛毯，能有效阻止熱力流失。不能疊厚毛毯，因為太重反而會讓被子內空間下墜，壓散熱空氣。
睡床>蓋毛毯>瞓上去>蓋被>蓋薄毛毯
