Key result

Volitional slow-deep breathing improves working memory accuracy ~8% during negative emotional distraction versus involuntary breathing.

MD 0.06
95% CI 0.01, 0.11

Why the study?

Breathing-based interventions are widely used to regulate emotional distress, but the biobehavioral nature of this effect has not been fully clarified.

Do different breathing strategies improve working memory performance and autonomic regulation under emotional distraction in healthy females?

Population

Implication

Slow-deep breathing may protect working memory under emotional stress; hypothesis-generating in healthy females and requires clinical validation.

Key Points

To examine how distinct volitional breathing patterns immediately modulate autonomic activity and preserve working memory during acute emotional distraction.
Healthy female participants (n = 54) completed a delayed match-to-sample working memory task under emotional distraction across three breathing conditions: involuntary breathing, volitional slow–deep breathing, and volitional fast–shallow breathing.
Working memory performance was quantified by accuracy, reaction speed, and rate correct score, and decomposed into latent decision components using a hierarchical diffusion decision model.
Cardiorespiratory and autonomic activity were continuously tracked by measuring breathing rate and depth, heart rate variability, respiratory sinus arrhythmia, heart rate recovery, and sudomotor orienting responses.
Volitional slow–deep breathing significantly improved working memory accuracy (estimated mean difference = 0.06, 95% CI [0.01, 0.11], t(156) = 3.34, p < 0.01) and reaction speed (estimated mean difference = 0.09, 95% CI [0.03, 0.15], t(156) = 3.69, p < 0.01) relative to involuntary breathing with negative distractors.
Slow–deep breathing enhanced cardiovagal indicators, including respiratory sinus arrhythmia (estimated mean difference = 0.86, 95% CI [0.46, 1.26], t(156) = 5.63, p < 0.001) and heart rate recovery (estimated mean difference = 0.66, 95% CI [0.06, 1.26], t(156) = 2.86, p < 0.05), while boosting decision drift rate (estimated mean difference = 0.24, 95% CI [0.17, 0.32], t(156) = 8.56, p < 0.001).
Volitional fast–shallow breathing accelerated reaction speed (estimated mean difference = 0.11, 95% CI [0.05, 0.17], t(156) = 4.63, p < 0.001) but did not improve accuracy (estimated mean difference = −0.02, 95% CI [−0.07, 0.02], t(156) = −1.35, p = 0.53), while reducing decision drift rate (estimated mean difference = −0.17, 95% CI [−0.24, −0.10], t(156) = −6.02, p < 0.001) and increasing sympathetic arousal.

Structured PICO

Do different breathing strategies improve working memory performance and autonomic regulation under emotional distraction in healthy females?

Population

54 healthy young women aged 18-29 years performed working memory tasks under emotional distraction to evaluate the immediate effects of different breathing strategies.

Intervention

Volitional slow-deep breathing and volitional fast-shallow breathing during working memory tasks with negative-emotion distractors

Comparator

Involuntary breathing during working memory tasks with neutral emotional stimuli (control distractors) or negative-emotion distractors

Outcome

Working memory performance (accuracy, reaction speed, rate correct score) and physiological functioning (heart rate recovery, respiratory sinus arrhythmia, heart rate variability, sudomotor activity)surrogate

Main Result

Mean Difference: 0.06 (95% CI 0.01–0.11)

Absolute Event Rate: 0.83% vs 0.77%

p-value: p=<0.01

Volitional slow-deep breathing preserves working memory performance under emotional distraction by enhancing parasympathetic dominance.

Limitations

Sample was restricted to healthy women aged 18-29 years, limiting generalizability to other sexes and age groups.
The stage division for early-later analysis was identified post hoc.
The design did not directly distinguish delayed behavioral responses from practice or general time-on-task effects.
20-trial task was not sufficiently long to evaluate later-emerging effects reliably
