Do blood pressure responses to slow breathing differ between men and women, and what are the autonomic contributors to these changes?

In one paragraph

Slow-Breathing Pacer Device, studied in 10, participants (J Appl Physiol 2019, PMID 31436511) — overall, slow breathing reduced systolic blood pressure by 3.2±0.8 mmHg. Cardiovagal baroreflex sensitivity improved during slow breathing (21.0 vs. 36.0 ms/mmHg), with no effect of sex.

Plain-English summary written and published by Magellan Longevity · medical review by Gabriel Radu, DO (physiatrist, NPI 1376861765). We summarize what the paper reported — we did not run this study.

The takeaway

Device-guided slow breathing effectively reduces blood pressure and sympathetic activity in both young normotensive men and women.

The question

Do blood pressure responses to slow breathing differ between men and women, and what are the autonomic contributors to these changes?

What they tested

An acute bout of slow breathing would induce larger decreases in blood pressure in males than in females, given that males typically have higher resting blood pressure.

How they did it

Normotensive females (n=10, age: 22±2 y) and males (n=12, age: 23±3 y) were tested at baseline and during the last 5 minutes of a 15-minute RESPeRATE-guided slow breathing session. Measurements included blood pressure, muscle sympathetic nerve activity, and spontaneous cardiovagal and vascular sympathetic baroreflex sensitivity.

What they found

Overall, slow breathing reduced systolic blood pressure by 3.2±0.8 mmHg. Females had lower systolic blood pressure, but there was no interaction between sex and slow breathing. Slow breathing also reduced muscle sympathetic nerve activity burst incidence by -5.0±1.4 bursts/100 heartbeats, with no interaction between sex and slow breathing. Cardiovagal baroreflex sensitivity improved during slow breathing (21.0 vs. 36.0 ms/mmHg), with no effect of sex.

Slow breathing reduced systolic blood pressure by 3.2 mmHg and muscle sympathetic nerve activity burst incidence by 5.0 bursts/100 heartbeats. Cardiovagal baroreflex sensitivity improved from 21.0 ms/mmHg at baseline to 36.0 ms/mmHg during slow breathing.

What it means

Slow breathing is equally effective in reducing blood pressure in both males and females, even in young, normotensive individuals, despite females having lower overall blood pressure. The RESPeRATE device is effective for reducing blood pressure in both sexes.

Limitations

The study was conducted on young, normotensive individuals, which may limit generalizability to other populations, such as those with hypertension.
