The science behind sound healing – why frequencies work

Although sound healing is often considered an alternative therapy, there are more and more scientific studies confirming its positive effects. Research shows that sounds and music not only improve mood, but also cause measurable changes in the body.

How sound affects our brain

Sounds influence brain activity by synchronising brain waves. Certain frequencies can promote alpha or theta waves, for example – brain waves associated with relaxation, stress reduction and even meditative states. These states help the nervous system switch to ‘rest and digest’ mode, which supports healing processes in the body.

Studies on stress and sound

One study found that listening to calming music significantly reduces the production of cortisol, a stress hormone. Another study showed that Tibetan singing bowls can lower heart rate and blood pressure, which reduces the risk of stress-related illnesses.

Why our bodies respond to sound

Our bodies are made up of around 70% water – a perfect conductor for sound waves. When sound vibrations pass through the body, they create microscopic vibrations that can have an effect at the cellular level. These vibrations help to release tension, promote blood circulation and induce a feeling of deep relaxation.

The bottom line: more than just sound

Sound healing is not just a “spiritual experience”, but a method based on measurable physiological reactions. The combination of frequencies, vibrations and conscious breathing can reduce stress, improve sleep and activate the body's self-healing powers.
