why do humans feel the urge to lick cuts/minor wounds.
In: Biology
Because licking a wound cleans dirt out, if it’s a burn then saliva cools the area, saliva also contains a clotting enzyme which helps stop bleeding.
It’s also diverting sensation. It’s the same as if you knock your shin, you rub it to help with the pain;your brain doesn’t want to focus on pain, pain is debilitating, so it focusses on other sensation. By licking your cut (or rubbing your leg) you’re stimulating other sensory neurones. Which help distract from the pan.
