Singing in a group for one hour doesn’t seem to make people with Parkinson’s disease more stressed, at least not based on their stress hormone levels.

Claim Language

Language Strength

association

Uses association language (linked to, correlated with)

The claim uses 'is not associated with' and 'suggesting it does not induce', which are phrased to indicate a lack of link or correlation rather than a definitive cause or effect, placing it in the 'association' category.

medicine

Population

human

Subject

An acute 1-hour session of group therapeutic singing

Action

is not associated with

Target

a significant change in cortisol levels in persons with Parkinson's disease

Intervention Details

Type: group therapeutic singing
Duration: 1 hour

The Effects of Group Therapeutic Singing on Cortisol and Motor Symptoms in Persons With Parkinson's Disease

Randomized Controlled Trial
Human
2021

The study had people with Parkinson’s sing together for an hour and checked their stress hormone levels before and after. The levels didn’t change, which means singing didn’t stress them out — just like the claim says.

Similar Assertions

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.

People with Parkinson’s who sing in a group may feel less stressed, because their body’s stress hormone (cortisol) goes down—especially after singing together 12 times.

After singing together in a group, people with Parkinson’s don’t show any clear link between how much their movement symptoms improve or worsen and how much their stress hormone (cortisol) changes.

Just one hour of singing in a group might help people with Parkinson’s feel a little less sad, even if it doesn’t change their movement or stress hormones.

When people with Parkinson’s sing together in a group for an hour, their heart beats faster—but when they quietly read instead, their heart slows down. This suggests singing gets their body more stirred up than reading does.
