Ran across this pilot study from April and the design stuck with me.

Most breathing research I have seen either happens in a lab or asks people to practice daily for a month before measuring anything. This one waited for real life. 47 university students got a prompt on their phones, and whenever a stressful situation actually showed up, they logged how anxious they felt. Then they were assigned a one-minute box breathing exercise, a one-minute cyclic sighing exercise, or no exercise at all. They rated it again five minutes after that.

Both breathing groups reported bigger drops than the control group. One minute, done in the situation, with no prior training.

The part I keep turning over is this. Students who score high on trait anxiety produced fewer impulse-control slips on a follow-up attention task after box breathing, and the effect was stronger for them than for the rest of the sample. Also worth noting, reaction times were longer in both breathing conditions than in the control. The authors flagged that as unexpected.

Small sample and a pilot design, so I would not oversell it. But it pushes back on the idea that you have to build the habit in advance for breathing to help you when things get tight.

Has anyone here used a one-minute technique in the moment rather than as a morning practice? Wondering whether it holds up outside a study.

Small 2026 study tested one minute of breathing during real anxious moments instead of as a daily practice
