Physiological Sigh (Cyclic Sighing)

What is Physiological Sigh (Cyclic Sighing)?

A breathing pattern consisting of two quick inhales through the nose followed by one long exhale through the mouth. Discovered by Stanford researchers as the fastest known way to reduce real-time stress. Just 1-3 cycles can shift you from sympathetic (fight-or-flight) to parasympathetic (calm) in under 30 seconds. Reddit users on r/selfimprovement call it 'the anxiety kill switch.'

Is there evidence for it?
