Make Me Smarter #12: Human corpses can continue to move for more than a year after death.
The thought of a body moving after a person has died sounds like something out of a horror movie, but it may just be a natural phenomenon. According to a 2019 study published in the journal Forensic Science International: Synergy and led by Australian researcher Alyson Wilson, corpses can continue to move for more than a year after death.
“What we found was that the arms were significantly moving, so that arms that started off down beside the body ended up out to the side of the body,” she told ABC News. “One arm went out and then came back in to nearly touching the side of the body again.” The movement is believed to be the result of the decomposition process which causes the corpses’ ligaments to dry out and contract, pulling the limbs as they do.
