Forensics Daily #9: Dead Wives Tales

Q: are the dead wives tales true at all? Meaning, our nails and hair do grow after we died ?

A: Yes and No. Yes, because it does look like it grows, like illusion. No, because it is NOT REALLY GROWING.. Both hair and nails look like they grow after the heart stopped working because of the skin surrounding them are dehydrated. They shrink, and thus make it appear to be longer. Funeral homes sometimes will moisturize the bodies when they are doing the prep to counteract this.

Other than the hair and nails, the chin also dries out, and pulling towards the back of a skull, thus looks like more prominent. So does the goosebump effect, because of the contraction around the hair muscle (remember we talked about in the last few q&a, after we died, our muscles are not able to relax, not unable to contract!).

These all biological responses give the sense of horror!
