發問:
我們的體溫是３７度例如３０度在我們的體溫比外界溫度高時理應熱能只會由我們的身體散失到空氣中但為何我們會感到熱？ 好像是我們的身體吸收了熱能
最佳解答:
因為我們身體是發熱體，如果外界溫度越高時，我們身體散失的熱量的速度便越慢。因此體內積蓄的熱便慢慢令身體溫度上升。所以你會覺得越來越熱。 另外身體機制會使身體排多一點汗去散熱，但外界溫度和濕度會影響汗液的揮發，因此也會引致熱能不積蓄和體溫上升。所以濕度高時，我們會覺得比較悶熱。
其他解答:
人的體溫是在身體與外界熱量交換的動態平衡中的結果.人不是一塊37度的死物,不是在外界溫度等於體溫時感到舒服,人在不斷地把來自食物的熱量散出體外,只有保持一定的散熱速度人才感到舒服,在37度或低一點(例如30度)散熱不暢,食物轉化來的熱量散不出去就會感到熱,就要出汗,靠汗的汽化吸去熱量,這時你扇一下幫汗汽化快一點,你就感到涼爽舒服.|||||Our body core temperature is 37degree C, but temperature of our skin is about 25 degree C. The feeling of hot is the sensor cells on our skin. The temperature we sense is the heat flow (gain or loss). When it is a windy day, even it is hot, you won't feel so hot. It is because our heat loss is larger when wind blow on our body. On the other hand, in winter, if there is no wind, heat loss is not great, we will not feel so cold. You will not feel hot or cold if you don't have the heat senser cells. Our eye will never feel cold (but feel pain) even in cold day or windy day since there are no feat senser cells. Summary: We feel hot or cold by the rate of heat loss.
