15. Why Do We Scratch An Itch?
It’s not that hard to figure out why we itch – there are several reasons for it, from dry, flaky skin, bedbugs, mosquito bites to acne. But what causes the urge for us to scratch the itch? If looked at objectively, scratching only offer temporary relief before the itch is back again.
In fact, if we scratch hard enough, it can worsen our skin condition and spread it to unaffected areas. So what is it that compels us to scratch? Scientists do know that itch receptors are similar to the receptors in our skin that perceive pain but still don’t exactly know how scratching can benefit us.
