Does the picture above make your skin crawl? You're not alone. A recent study conducted by the University of Manchester
found that visual cues
-- such as being shown an image of an ant or a bug bite -- can provoke an itch response in people
, even if they haven't felt a thing. In fact, you may not even need to see the itch inducing stimulus, as the same study found that just seeing another person scratch can make viewers feel that they also have an itch to scratch
, suggesting that itching, like yawning, may be a socially contagious response.
