Singing consistently lowers cortisol, the primary stress hormone, as proved by multiple studies measuring saliva levels before and after vocalization.
A 2017 Royal College of Music study found a marked decrease in cortisol following a singing session, while research on cancer patients and carers confirmed that singing alters cortisol level alongside other stress related signs.
