Sound healing, or sound therapy, is the practice of using different sound vibrations to improve mental and physical health. While it has long been related to ancient rituals, experts are consistently looking into its effects, and there is now scientific evidence that it works. But how does it work, exactly?

We already know that music plays an important role in our daily lives. The kind of music we listen to affects our mental state, which is why we create different playlists for every mood. And as we already know, mental well-being is closely linked to physical health.

How does sound healing work?

Sound healing works around the principle that when the body is sick, it is "out of tune" and so the vibrations will restore the body's resonance. This follows the idea that everything around us with movement provides sound vibrations, even if we do not hear all of them. 

Our cells are constantly moving, which means they are also constantly producing vibrations at a certain resonance frequency. If an external factor with its own frequency - in this case, that which is brought by sound therapy - comes in contact with those vibrating cells, the cells would adjust to match that frequency and perform at optimum levels.

In a study conducted in 2016, exposure to sound therapy in the form of Tibetan singing bowl meditation resulted in less tension, anger, fatigue and depressed mood in 62 participants. 

A more recent study also showed that listening to music at particular frequencies had different effects. At 432 Hz, participants were found to have improved blood pressure, heart rate and respiratory rate compared to the same parameters when they listened to music at 440 Hz.

There may still be a lot of questions about sound therapy, but the foundation of how it works has already proven it to be instrumental in improving mental and physical health.
