Why Do Paper Cuts Hurt So Much
Some of the most infuriating and stabbing pain is caused by nothing but a thin sheet of paper. WE explain why the page of a book can sometimes cause more anguish than a blade.
Paper cut are usually small and shallow injuries so why do they hurt so much a close look at the anatomy of our skin and the structure of paper reveals a few explanations we usually get paper cuts on our hands and fingers where skin is packed with neurons some of these neurons called
nociceptors detect potential harm these cells respond to high temperatures harsh chemicals than any pressure that threatens to break the skin nociceptors trigger a cascade of electrical and chemical signals that eventually reach the brain informing it about injury in turn our brain makes us aware of injury with the experience of pain also paper cut is not quite as clean as it looks a paper edge may seem perfectly smooth but on a microscopic level it's actually pretty jagged a thin piece of paper cuts through skins more like a saw than a knife ripping apart our cells and paper leaves behind chemical coated particles irritating the wound another thing since paper cuts are generally shallow they don't bleed or clot very much that means damaged tissues and neurons remain exposed every time we use our hands the wound flex is open disturbing these neurons finally we should also consider the psychology of a paper cut we probably pay more attention to a paper cut because it's on a body part we use so often it's also surprising and kind of upsetting to be injured by something as seemingly benign as paper.
