He calls it the physiological sigh: two quick inhales through your nose, followed by one long, slow exhale through your mouth. This simple pattern is hardwired into the body to release stress.
When you do it, your heart rate slows, carbon dioxide drops, and your brain shifts from “fight or flight” into “rest and repair.”
A 2021 study found that just 1–5 minutes of this breathing each day lowered stress and boosted mood more effectively than meditation.
Another 2023 paper confirmed that controlled breathing activates the parasympathetic nervous system, improving calm and emotional regulation.

The takeaway: when anxiety spikes or stress builds up, a few intentional breaths can rewire your state in minutes.
