Do sound baths work?

Someone sits up after a sound bath and says it’s the most relaxed they’ve felt in months. Then somebody else asks whether any of that’s real. We book sound baths, so we looked into the research on them. There isn’t much of it yet.

If by “work” you mean feeling calmer and less tense afterwards, a few small studies suggest they can. The best-known one, from 2017, surveyed 62 adults (average age about 50) before and after sound meditations of about an hour, played on singing bowls, gongs and bells. Afterwards, people reported less tension, anger, fatigue and low mood.

The authors called it “a nonrandomized observational study without a control group,” so there was no group of people who skipped the session to compare against. Everyone there had also chosen to come, and lying still for an hour can be relaxing on its own.

In a 2023 trial, 50 adults who were feeling anxious were assigned at random to one session of singing bowls, one session of a standard relaxation exercise (tensing and releasing each muscle group), or a waiting list. Both sessions lowered anxiety compared with waiting, and the singing bowls lowered it a little more. There were about 17 people in each group, though, and everyone had one session and was measured straight afterwards.

They haven’t been proven yet. A 2020 review looked for every published study of singing bowls and health and found four. Its conclusion was “we cannot recommend singing bowl therapies at this stage.” A 2025 review found 19 studies, of mixed quality, and said singing bowls “may have potential” for anxiety, low mood and sleep.

What people feel and what instruments measure can also differ. In a 2020 study, 48 healthy adults lay in a hammock over a large bowl, once with the bowl struck and once with it silent. They said they felt slightly less sleepy after the struck bowl, while a measurement of sleepiness taken from the pupils of their eyes showed no difference. One of the authors owned the foundry that makes the bowls, and the paper says so.

The same pattern shows up with music and sleep. The Cochrane review of music for insomnia, which pulls the trials together, found that people who listen to music at bedtime report sleeping better, while the instruments that measure sleep show very little change.

We didn’t find any study showing that particular frequencies or vibrations do specific things to the body, or that a sound bath treats any condition.

The sound bath we book is Firstwater’s. It’s seventy-five minutes with one facilitator, who brings the sound system, the mats and the blankets. People lie down, the lights go low, and there are live instruments played over music composed for the session. Anyone who can’t lie on a mat can rest in a seat, and nobody is asked to speak or share.

A sound bath is an hour or so of rest, with sound that a lot of people find easy to relax to. For a team, a studio or a retreat, that’s a reasonable thing to want, and it’s a good reason to book one.
