Several research activities have been conducted to study the efficacy of singing bowls to date. This includes the systematic survey, randomised controlled trial, study of neurophysiological effects and experimental study on animals. The summary of each study is presented below.
- Fresh Systematic Review (2025): A recent systematic review article (PubMedDOAJ) analysed all clinical studies on singing bowl therapy available up to July 2024—covering 19 clinical studies (9 RCTs and various observational designs) across diverse populations (e.g., elderly, post‑surgery, Parkinson’s, depression, anxiety, sleep disorders, autism, and more). Findings include the potential benefits in reducing anxiety, improving sleep quality, alleviating depression, and enhancing cognitive function, as well as measurable physiological changes like EEG alterations.
-
Systematic Review on Tibetan Singing Bowls (TSB): Another systematic review (PubMed) of Singing Bowls interventions, including 14 quantitative studies up to early 2025, also found similar results, such as significant reductions in anxiety and depressive symptoms, improved well-being and quality of life, enhanced heart rate variability, decreased heart rate, and shifts in brainwave patterns (increased delta/theta activity). Findings include interesting things such as non‑invasiveness, low‑risk nature of TSB, and a feasible complement in clinical or community settings—while advocating for rigorously designed future trials.
-
Randomized Controlled Trial on Tibetan Singing Bowls: A 2023 RCT study (MDPIPubMedPMC) compared a single session of Tibetan singing bowl sound (TSB) treatment with progressive muscle relaxation and a waiting-list control in a sample of anxious but nonclinical adults. Findings include the significantly greater increases in heart rate variability, sharper reductions in EEG alpha power, and more pronounced decreases in self-reported anxiety. This concludes that TSB may induce an acute relaxation response, potentially useful in stressful or pre‑intervention contexts.
-
Neurophysiological Effects of Singing Bowl Massage: In a cohort study (PubMedPMC) capturing EEG, ECG, and respiration before, during, and after professional singing bowl massage. Findings include a significant decrease in beta2 and gamma bands, a reduction in heart rate and an increase in respiration rate and resulting in a meditative state.
-
Experimental Study (Animal Model): Vibration Effects: Beyond human trials, a recent animal study (Lippincott Journals) explored how the vibrational component of singing bowls (separately from sound) influenced anxiety, using stressed or sleep-deprived mice. Findings include the reduction of anxiety-like behaviour and led to molecular and neural changes in the brain (e.g., modulation of NMDA receptors, GABAergic interneurons, reduced aberrant gamma oscillations).
The recently published body of research up to mid-2025 paints a cautiously optimistic picture: singing bowls—particularly Tibetan singing bowls—demonstrate measurable psychological and physiological benefits, notably in reducing stress, anxiety, and improving well-being.
