Healing music and drum circles are gaining recognition as complementary therapies for veterans and first responders suffering from PTS. Research shows that music therapy can significantly reduce PTS symptoms, with studies noting a 39% reduction in anxiety and a 34% reduction in depression among participants, alongside improved mood and emotional regulation. 

Neurobiological effects include increased levels of dopamine and serotonin, which are linked to stress reduction. Drum circles also show promise, with participants experiencing a 20-30% reduction in PTS symptoms such as anxiety and flashbacks, as well as physiological benefits like reduced cortisol levels and increased endorphin production. 

These therapies, while still being studied, offer valuable non-verbal outlets for emotional expression and can foster community and connection, making them effective components of a holistic PTS treatment approach.
