The claim
Mouth taping went viral in 2023. The pitch is simple. Tape your lips closed, force yourself to breathe through your nose, and enjoy deeper sleep, less snoring, and better health. Some creators even promise sharper thinking and younger-looking skin. The tape costs almost nothing. The promises cost nothing to make.
What the review found
In May 2025, researchers published a systematic review in PLOS One. They screened 120 records and kept 10 studies with 213 patients total. That is a small evidence base for a global trend.
The result: only small, inconsistent improvements, limited to a mild sleep-apnea subgroup. No miracle. No transformation. Just weak signals in a narrow group. Read the review: Rhee et al., PLOS One, 2025.
The safety problem
Four of the studies raised asphyxiation risk when nasal airflow is impaired. Congestion, a deviated septum, or allergies can turn a strip of tape into a breathing hazard. Many of the trials excluded people with nasal obstruction entirely. The influencers never mention that exception.
The American Lung Association issued a formal warning in early 2026. That is not a vibe. That is a medical authority telling you to stop.
What actually helps
If you snore, treat the congestion first. Try side sleeping. If you snore loudly, gasp, or wake up exhausted, talk to a doctor about sleep apnea. Real apnea has real treatments. Tape is not one of them.

Questions, answered
Does mouth taping stop snoring?
The evidence is weak and inconsistent. The 2025 review found only small effects, limited to people with mild sleep apnea.
Is mouth taping dangerous?
It can be when your nose is blocked. Four studies flagged asphyxiation risk with impaired nasal airflow, and the American Lung Association warned against it in 2026.
What should I do about snoring instead?
Treat nasal congestion and try side sleeping. If snoring is loud or you gasp at night, talk to a doctor about sleep apnea.
