Because that's the temperature at which many of the molecules in our bodies operate at their most efficient, and enzymes is the best example of that.

因为在正常体温下,体内许多分子活性最高,酶就是其中最好的例子

耶鲁公开课 - 生物医学工程探索课程节选

Enzymes work best, enzymes are proteins that catalyze chemical reactions and our bodies operate by elaborate networks of chemical reactions, When we're off from that temperature then they don't work properly.

举酶这个例子再好不过,酶是一种具有催化作用的蛋白质,人体依靠精密复杂的化学反应网络来运转,如果我们体温与之相差较大,这些酶就不能正常工作
