'''Irritation''' or exacerbation, in [[biology]] and physiology, is a [[state]] of inflammation or [[painful]] [[reaction]] to allergy or cell-lining damage. A stimulus or [[agent]] which induces the state of irritation is an irritant. Irritants are typically [[thought]] of as [[chemical]] agents (for example [http://en.wikipedia.org/wiki/Phenol phenol] and [http://en.wikipedia.org/wiki/Capsaicin capsaicin]) but [[mechanical]], thermal ([[heat]]) and radiative stimuli (for example ultraviolet [[light]] or ionising radiations) can also cause it. Irritation also has non-clinical usages referring to bothersome [[physical]] or [[psychological]] [[pain]] or discomfort.
