The act of scratching an itch can evoke a mix of pleasure and misery. A scientific study of rat itching, reported in the January 31 issue of Science, has highlighted this paradox and may provide guidance on how to reduce the effects of insidious itching in humans.
Dermatologists and immunologists at the University of Pittsburgh conducted a study that combined studies of skin and fungi to reveal a link between itching and inflammation. Get Science news headlines delivered straight to your inbox.
According to the researchers, the mice that reacted to the small cones of shame had lower levels of inflammation than those that did not. Kaplan suggests the findings are similar to mosquito bites, saying the initial itchiness in most people lasts five to 10 minutes, while those who start scratching later have a significant amount of swelling and the lesion may persist for several days.
Despite the fact that scratching may help reduce the number of harmful bacteria on the mice’s skin, it also boosts their immune system.
According to Kaplan, scientists have recently discovered new information about itching and developed new ways to deal with its persistent and painful symptoms. This new study may provide new information about treatment options.
Kaplan suggests that a person should tolerate itching or be wary of it based on both factors.
