What the research supports

Research supports that rhythmic sound can influence measurable brain activity and that delta, theta, alpha, beta, and gamma bands are associated with different states of sleep, relaxation, focus, and attention. Evidence for specific Solfeggio healing claims is more limited and remains emerging or traditional.

Use sound responsibly

Use a comfortable, low volume and stop if listening causes discomfort. Consult a qualified healthcare professional before use if you have a medical condition, seizure disorder, implanted cardiac device, or concerns about pregnancy or mental health.

Read the HealHz research blog for more context on the evidence and limitations behind sound-based wellness tools.
