{{Redirect|Sigh}}
A '''sigh''' is a kind of paralinguistic respiration in the form of a deep and especially audible, single [[exhalation]] of air out of the mouth or nose, that humans use to communicate emotion. It is a voiced [[pharyngeal fricative]], sometimes associated with a guttural glottal breath exuded in a low tone.  It often arises from a [[negative affectivity|negative emotion]], such as dismay, dissatisfaction, boredom, or futility.<ref name="Broncher"/> A sigh can also arise from positive emotions such as [[Relief (emotion)|relief]],<ref>Paul Ekman, ''Emotions revealed: recognizing faces and feelings to improve communication'' (2007), p. 193.</ref> particularly in response to some negative situation ending or being avoided. Like a gasp, a [[yawn]], or a [[moan]], a sigh is often an automatic and unintentional act.<ref name="Broncher"/> 

Scientific studies show that babies sigh after 50 to 100 breaths. This serves to improve the mechanical properties of lung tissue, and it also helps babies to develop a regular breathing rhythm. Behaviors equivalent to sighing have also been observed in animals such as [[dog]]s, [[monkey]]s, and [[horse]]s.

In text messages and internet chat rooms, or in comic books, a sigh is usually represented with the word itself, 'sigh', possibly within [[asterisk]]s, *sigh*.

Sighing is also a reflex, governed by a few [[neuron]]s.<ref>{{Cite web|url=http://newsroom.ucla.edu/releases/ucla-and-stanford-researchers-pinpoint-origin-of-sighing-reflex-in-the-brain|title=UCLA and Stanford researchers pinpoint origin of sighing reflex in the brain|last=Schmidt|first=Elaine|website=UCLA Newsroom|language=en|access-date=2019-02-01}}</ref>
