Researchers studied 117 volunteers attending two concerts of music by composer Eric Whitacre - one at Gloucester
Cathedral, the other at the Union Chapel in London.
The volunteers provided saliva samples before the performances, and then again during the interval an hour later. Testing the samples for levels of cortisol and cortisone, researchers recorded across-the-board reductions in the second samples.
Cortisol is produced by the body under physical or psychological stress. It can have a positive effect in small doses, improving alertness and well-being.
However, chronically elevated cortisol levels can worsen medical conditions such as heart disease, diabetes, hypertension and
impotency.
