Myth 4: Fingernails and hair continue to grow after death
误解四:指甲和头发在人死后还会继续生长
Our bodies do lots of creepy things after we die, but they don't keep growing our fingernails and hair. To do that, our bodies need to produce new cells - something that simply isn't possible after death.
我们的身体在我们死后还会做很多让人毛骨悚然的事情,但我们的指甲和头发在死后并不会继续生长。如果要继续生长,人体需要制造新细胞,而这在人死后是根本不可能发生的。
This morbid misconception dates back until at least 1929 when writer Erich Remarque immortalised it in his novel All Quiet on the Western Front. In fact, his misunderstanding is due to an optical illusion.
这种病态的误解要追溯到至少1929年,当时作家埃里希•雷马克在他的小说《西线无战事》中让这种观念深入人心。事实上,雷马克的误解源于光学错觉。
While our nails and hair don't continue to grow after we breathe our final breath, our skin does "shrink" as it becomes dehydrated. As the skin retracts, our nails and hair become more exposed, and, thus, they may appear to grow.
在我们断气后,我们的指甲和头发并不会继续生长,但我们的皮肤会因为脱水而收缩。皮肤收缩后,我们的指甲和头发会更多地暴露在外,因此它们看上去就好像继续生长了。
