Stillness · Breathing Space

A breath pacer with a light wind and a warm drone: a rising tone marks the in-breath and a fading tone the out-breath. The first two minutes use a shorter, easier pace (7.5 breaths a minute), then six a minute, and 5.5 in the last part: the space between breaths slowly widens. In the last minute the tones stop and you breathe at your own pace. Follow without forcing and don't hold your breath; if the pace doesn't feel comfortable, return to your own rhythm.

10 minNo headphones neededreviewed 7 October 2026

The same recipe with another seed: the raindrops, the order of the birds or the path of the chords change; the rules and evidence level stay the same.

Breathe slowly in time with the sound without forcing it, and don't hold your breath. If you feel dizzy or uneasy, return to normal breathing. If you have epilepsy, are pregnant, or have a heart or breathing condition, talk to your doctor first.

Do not listen while driving or operating machinery.

  • Reverb: room, 18% mix

In the room you can listen to each layer on its own, change its settings and save it as your own recipe.

Sound is generated on this device in real time; no files are downloaded from a server. There is a 4 s fade-in at the start and a 0 min fade-out at the end.

Compare with another sound

Hear both at the same loudness; drag the slider to the middle and they blend.

In the middle the two sounds truly blend; loudness is matched.

8 trials, half of them the same sound; get at least 7 right and the difference is audible. The result stays on this device.

B · Moderate evidenceLast reviewed 7 October 2026

A few controlled studies or meta-analyses; reasonable but limited generalisability.

Slow breathing and heart rate variability

Guides your breathing down to about six breaths a minute; slow breathing can support a body response linked to relaxation.

What do we know?

  • SupportIn a meta-analysis of 223 studies, voluntary slow breathing increased vagally mediated heart rate variability during breathing, immediately after a session and after multi-session programmes.Laborde et al. 2022
  • SupportBiofeedback training that teaches pacing to heart rhythm was also linked to a large reduction in self-reported stress and anxiety.Goessl et al. 2017

What don't we know?

  • Evidence gapThe effect comes from slower breathing; no effect of the sound itself has been shown.
  • Evidence gapSome studies used device-based biofeedback; whether pacing with sound alone gives the same result has not been tested separately.Goessl et al. 2017
  • Any advantage of searching for a personal breathing rate is outside this claim.

Breathwork and stress

A slow breathing break can accompany your stress-management routine.

What do we know?

  • SupportIn a meta-analysis of 12 randomised trials, breathwork was linked to a small-to-medium reduction in self-reported stress compared with non-breathwork controls (g = −0.35).Fincham et al. 2023
  • SupportBiofeedback-based breathing training also showed a large reduction in stress and anxiety.Goessl et al. 2017

What don't we know?

  • LimitMost studies carry moderate risk of bias and the techniques vary widely; which technique works is unclear.Fincham et al. 2023
  • Techniques with fast breathing or breath holding are outside this product's scope.
  • LimitIn a meta-analysis of 31 studies, slow-paced breathing raised heart rate variability, but its effect on perceived stress was only borderline (p = 0.06).Shao et al. 2024

Sources and review note

A session's level is the weakest of its linked claims; it is never raised by a strong but unrelated claim.
