When adults with Parkinson’s sing in a group, their stress hormone levels sometimes drop, and when that happens, they seem to feel less pain—but only during the first two singing sessions, not the third. So the connection might just be temporary or unpredictable.

Evidence from Studies
Supporting (1)
The study found that singing in a group made people with Parkinson’s feel less pain, and this was linked to lower stress hormone levels — but only sometimes, not every time, which matches the claim.
