Sighs are especially audible, single exhalations of air out of the mouth or nose, that humans use to communicate emotion. It often arises from a negative emotion, such as dismay, dissatisfaction, boredom, or futility. A sigh can also arise from positive emotions such as relief, particularly in response to some negative situation ending or being avoided.
