Some people are taping their mouths shut to improve sleep, but doctors advise against this practice. Social media claims it reduces snoring and enhances sleep, but there's no scientific backing. Experts warn it could worsen sleep disorders like sleep apnea or even cause suffocation. Dr. Kimberly Hutchison from Oregon Health & Science University highlights the risks. Mouth breathing isn't ideal, she says, but taping isn't a solution. Dr. David Schulman of Emory University suggests alternatives like CPAP machines or prescription mouthpieces. Identifying the cause of mouth breathing, such as sleep apnea, is crucial. A sleep test can provide answers.
