The notion that a chill puts you at risk of catching a cold is nearly universal. Yet science has found no evidence for it. One of the first studies on the matter was led by Sir Christopher Andrewes. He took a group of volunteers and inoculated them with a cold virus; previously, half of the group had been kept warm, and the other half had been made to take a bath and then to stand for half an hour without a towel while the wind was blowing on them. The chilled group got no more colds than the warm group.
