许多人可能都会有这样的经历:冬天在外面冻了半天之后,往往会非常尿急。这是为什么呢?今年第二期的三联生活周刊上有一篇文章给出了解释。
文章说,液体杂质越多,其冰点就越低。而血液越浓稠,就越不容易被冻成冰。人在挨冻时,身体会排出血液中过多的水分,使血液更加粘稠,这样才不至于被冻僵。因此,这个时候,绝大多数人都会尿急。
也正因为这个原因,糖尿病人有天生的抗寒能力。
呵呵,这个科普不错

Good info.
Means that when someone is nervous, he or she will generate less heat and thus also need to go toilet.
发冷!
