Two inhales through the nose — a full one, then a short top-up — followed by a long exhale through the mouth. The second inhale reinflates collapsed air sacs so the exhale can offload more carbon dioxide.
This is the one to reach for in the moment rather than as a daily practice. Controlled trial evidence supports cyclic sighing for acute mood and arousal, performing at least as well as an equal dose of mindfulness meditation. It works within a handful of breaths and is discreet enough to use in a corridor.
