They are, after all, slow-moving beasts.
Symphony of Sloths producer Marika Pratley admits she is not medically trained, but feedback from people who have seen the show provides anecdotal evidence of healing of the most holistic nature.
One person had reported their soul was healed - another their physical pain.
These are things art can do.
''We're inspired by the essence of the sloth animal,'' Pratley said.
''So it's one of those things that has inspired me as I've grown up. I feel like there are less spaces as an adult to be creative.
''Creativity gets policed out of children as they grow up.''
Symphony of Sloths is a musical piece with input from all the performers.
''It's humans behaving like sloths playing music,'' Pratley says.
''It's not like a play, it's a musical experience that's quite meditative.
''People need to commit time to themselves generally to be able to relax and enjoy simple things.''
