Air exposure makes paper cuts hurt
Q: Why do some paper cuts hurt more than deeper cuts?
A: It's not just paper cuts. Any shallow cut-whether made by paper or a sharp plastic edge-hurts more than a deep cut because the shallow one remains open. The body quickly seals, with a blood clot, a deeper cut that bleeds. Indeed, any wound not sealed off, like an ulcer or a burn, hurts and, as soon as the doctor covers the open wound with a gel dressing, the pain lessens. Try it the next time you get a paper cut. Cover your cut with a gel dressing made for ulcers and feel the tenderness lessen.
