At a physiological level, low-tempo tracks could help to entrain the electrical activity in the brain stem to slower rhythms, which can bring about a more tranquil mood and regulate other biological processes – such as heart rate and respiration. Repeating musical motifs, producing a buildup and release of tension, are also known to play with the brain’s prediction and reward circuitry. This can trigger the release of neurotransmitters such as dopamine and endogenous opioids, which ease both emotional and physical pain. At its most extreme, we may feel these neurochemical changes as musical frisson or “chills” – an intense aesthetic experience.

I know the idea of music having healing and therapeutic properties isn’t new, but I do wish there was more accessible research done on the topic of music and (especially physical) health.
