Being straight with you
What the research actually says
A 2025 systematic review in Healthcare gathered fourteen quantitative studies of Tibetan singing bowl interventions from the previous sixteen years. It concluded they demonstrate potential for stress reduction and psychological well-being as a non-invasive complementary method, with most studies reporting less anxiety, improved heart rate variability and lower heart rate.
The same review is candid about the weaknesses, and so are we: the certainty of the evidence ranged only from low to moderate, sample sizes were mostly small, the studies varied too much to pool, and few followed anyone up over the longer term.
So there is real published signal, and it points in a consistent direction. That is not the same as proof. Anyone telling you sound healing cures disease is going beyond what the evidence supports. We offer these sessions for rest, for relief from tension, and for a nervous system that has forgotten how to switch off. That is what they are good at.
