What does Resonant Breathing do to the body?
Resonant breathing slows the breath to about six cycles a minute, well below the usual resting pace, and during practice it has been measured to raise heart rate variability, the moment-to-moment variation in the spacing of heartbeats, and to sharpen the baroreflex, which automatically adjusts heart rate to keep blood pressure steady (Gross et al., 2016), (Masahito et al., 2020). In the body this tends to feel like the chest and shoulders loosening, the pulse smoothing out, and the whole system settling into a slower, less braced rhythm. These changes are recorded mostly during the breathing itself, in small studies, so a lasting shift in your everyday baseline is not yet established.
Respiratory Rate
direct EVIDENCE
The slower rhythm often feels like the chest and shoulders loosening and the whole body settling into a steadier, less hurried tempo. During resonant breathing the breath drops to roughly six cycles a minute, well below the everyday resting pace, so respiratory rate, the number of breaths you take each minute, falls during practice (Gross et al., 2016), (Masahito et al., 2020).
Parasympathetic Tone
moderate EVIDENCE
The breath slowing and the body settling during resonant breathing lines up with a measured rise in parasympathetic tone, the rest-and-recovery branch of the nervous system, seen as increases in vagally driven heart-rate variability while people breathe at around six breaths a minute (Gross et al., 2016), (Masahito et al., 2020). Many people notice this as the shoulders and jaw loosening, the breath deepening on its own, and a sense of urgency easing.
Interoceptive Accuracy
moderate EVIDENCE
When you practise resonant breathing, your ability to read internal body signals, the timing of the heartbeat, the movement of the breath, has been measured to sharpen (Leganes‐Fonteneau et al., 2021), (Wareing et al., 2024). Many people feel this as being more tuned in to the body, noticing the first signs of tension or stress earlier, before they build.
