TAP reading note: Brief structured respiration practices enhance mood and reduce physiological arousal
Brief daily breathing practice, particularly cyclic sighing, showed relative benefits for positive affect and respiratory rate. Between-group differences in negative affect and state anxiety were not significant, and HRV, resting heart rate and sleep did not change significantly. Mood benefits should be read alongside these null physiological findings.

What the study found
Brief daily breathing practice, particularly cyclic sighing, showed relative benefits for positive affect and respiratory rate. Between-group differences in negative affect and state anxiety were not significant, and HRV, resting heart rate and sleep did not change significantly. Mood benefits should be read alongside these null physiological findings.
Scope & limitations
Remote exploratory trial of 108 people: mindfulness 24, cyclic sighing 30, box breathing 21 and cyclic hyperventilation with retention 33. Figure 4 physiological analyses included 100.
Small groups, remotely estimated adherence, retrospective registration and no long-term follow-up constrain interpretation. Eight households received the same condition; consequences for statistical independence remain to be checked. Within-group improvement does not replace a between-group comparison.
Population & sample
Remote exploratory trial of 108 people: mindfulness 24, cyclic sighing 30, box breathing 21 and cyclic hyperventilation with retention 33. Figure 4 physiological analyses included 100.
Exposure or intervention
Approximately five minutes daily of three structured breathing practices versus mindfulness meditation.
Outcomes
Positive/negative affect, state anxiety, respiratory rate, HRV, resting heart rate and sleep.
Time frame
28 days, without a test of long-term maintenance.
Research funding
Victor and Winnie Koo, Tianren Culture and Stanford support; WHOOP donated wrist devices.
Research conflicts of interest
The paper reports no WHOOP role in design or analysis. A. D. Huberman became a WHOOP adviser in June 2022.
Reading scope
Full-text participant flow, affect/physiology/sleep results, statistics and limitations. Household allocation, adherence and all supplementary figures remain to be examined.
