Researchers at Western University in Canada recently reviewed 10 previously published studies that examined mouth taping as far back as 1999. Their resulting paper published on May 21 in PLOS One lays out what may be a pretty predicable conclusion: Please don’t try mouth taping at home without consulting an actual medical professional. “Mouth taping is a contemporary practice that is often celebrity-endorsed, but is not necessarily scientifically accurate,” the study’s authors explained in a statement. Meanwhile, other studies didn’t determine any evidence to support taping your mouth for reducing sleep-disordered breathing, snoring, or apnea. The reviewers note there appears to be a “very specific use-case scenario” for people with mild obstructive sleep apnea.
