Is Mouth Taping Safe? What the Research Actually Says

Mouth taping went from niche biohacker habit to millions of TikTok views in about a year. The pitch is simple: tape your lips at night, breathe through your nose, wake up better. We sell a gentle mouth tape ourselves, so we think you deserve a straight answer on what the evidence actually shows.

What the research found

In 2025, a team of Canadian researchers published a systematic review in PLOS One that pulled together the published studies on mouth taping during sleep. They found 10 studies with a little over 200 people in total, mostly people with snoring or mild sleep apnea.

• Benefit was rare. Only two of the studies found a meaningful improvement on sleep-apnea measures. Most found no clear difference.
• The studies were small and uneven in quality. The authors said better research is needed before anyone can recommend it.
• Safety concerns came up. Several studies flagged risks, especially for people who can't breathe freely through their nose.

The authors' biggest worry was not the tape itself. It was people using tape to quiet snoring and never finding out they have sleep apnea, a common condition that deserves a doctor's attention.

Who should not tape their mouth

• Anyone with sleep apnea, or who suspects it: loud snoring, gasping or choking at night, or feeling exhausted after a full night in bed.
• Anyone with a blocked or stuffy nose, a cold, allergies flaring, or trouble breathing through the nose for any reason.
• Anyone who feels nauseous, or who has had alcohol or sleep medication that night.
• Children.

If you snore loudly or wake up gasping, skip the tape and talk to a doctor. The NHLBI has a clear overview of the signs.

If you still want to try it

Some healthy adults simply like the feeling of a closed mouth at night and a less dry mouth in the morning. If that's you, a few rules make it gentler:

• Do a nose check first. Close your mouth and breathe only through your nose for a few minutes while awake. If that feels hard, tape is not for you.
• Never seal your mouth fully. Choose a strip with an opening, not regular tape across the whole mouth.
• Use skin-friendly tape that peels off easily. Never use household, duct or surgical tape.
• Stop if anything feels off: anxiety, air hunger, waking up with the strip already pulled off, or skin irritation.

And keep expectations honest. Tape is a comfort habit, not a treatment for snoring or any breathing condition.

From the Celliden shelf

Our Night Strips are soft cotton strips with a center vent, so you are never sealed shut, and they peel off in one motion. Please read the safety notes on the product page before using them. Prefer no tape at all? The Soft Chin Strap is the tape-free option. Both are comfort accessories, not medical devices.
