Effects of Singing Bowls

What Happens in a Sound Bath?

People often ask me what, exactly, is happening during a sound bath. They arrive a little cautious — maybe curious, maybe sceptical — and they leave looking different. Something has shifted. The shoulders have dropped. The breath has slowed. Whatever they were carrying when they walked in feels, somehow, lighter.

I’ve been leading sound baths for years, and I still find that quiet transformation remarkable. I’m also someone who appreciates a good question — and “why does this work?” is one worth exploring. Fortunately, researchers have started asking it too.

What the Science Tells Us

The most widely cited study in this field was published in 2017 by Goldsby and colleagues in the Journal of Alternative and Complementary Medicine. They looked at the effects of singing bowl sound meditation on mood, anxiety, and spiritual well-being across 62 participants. The results were notable: after a single session, participants reported significantly less tension, anger, fatigue, and depressed mood. Spiritual well-being increased meaningfully across the group. And for those who had never experienced singing bowl meditation before, the reduction in tension was even more pronounced than for those who already had a practice.

That last finding stays with me. There’s something about arriving without expectation — open, receptive — that seems to allow the experience to land more fully.

The Goldsby study used Tibetan metal singing bowls. The instruments I work with are different — frosted quartz crystal bowls — and a 2023 pilot study published in the Journal of Psychiatry and Behavioral Sciences looked at exactly those. Researchers at Waikato Hospital in New Zealand had eleven adolescent males lie on mats and listen to relaxation music played on crystal singing bowls for 25 minutes. Immediately afterward, depression scores fell significantly, and tension scores trended meaningfully in the same direction. The researchers concluded that even a single session may improve mood, and called for larger studies to explore this further.

The field is still young. But the patterns that emerge from these early studies consistently point in the same direction.

Why Sound Works on the Body

The science of why this happens is still developing, but a few threads are worth following.

Sound is vibration. When a crystal singing bowl is played, it doesn’t just produce a tone that travels to your ears — it creates vibration that moves through the room, through the floor, through you. The body resonates with what surrounds it. That’s not metaphor; it’s physics.

Research using EEG has also shown that singing bowl listening can shift brainwave activity toward lower-frequency states — the delta and theta waves associated with deep relaxation and meditative awareness. What I appreciate about this is that it happens passively. You don’t need to know how to meditate. You don’t need to quiet your mind by force. You simply need to be present and let the sound do its work.

There’s also the nervous system to consider. When we’re stressed or anxious, the body holds tension — in the muscles, in the breath, in the way we hold ourselves. The slow, sustained tones of a sound bath give the nervous system permission to release that hold. Heart rate settles. Breathing deepens on its own. The body finds its way back to a state of ease, often without the person even noticing it’s happening.

What I Notice in the Room

Science can name what’s happening at a neurological and physiological level. I experience it differently — as a practitioner, watching something unfold in people I’ve just met.

What I notice most is the quality of stillness that settles in a room about ten minutes into a session. It’s almost tangible. Faces relax. Fidgeting stops. People who arrived distracted or preoccupied seem to come back to themselves. Some experience vivid imagery, or a quiet wave of emotion. Some simply fall into a deep, nourishing rest.

All of it is welcome. None of it needs to be explained or achieved. That’s one of the things I love most about this work — there’s no right way to receive a sound bath.

If You’re Curious

The research is growing, and what it consistently points toward is this: singing bowl meditation is accessible, gentle, and capable of producing real shifts in how we feel — in tension, in mood, in our sense of well-being. You don’t need any prior experience, and you don’t need to do anything except arrive and lie down.

If you’d like to experience that for yourself, we’d love to have you join us for a session.
