Physiological Sigh

The physiological sigh is the pattern your body already uses on its own when you cry or before sleep: two inhales back to back, then a long, slow exhale. A 2023 Stanford study found that just five minutes a day of cyclic sighing improved mood and lowered breathing rate more than mindfulness meditation alone.
