Mouth Taping for Better Sleep: Hack, Hype or Just Not for You?
Episode Overview
- Nasal breathing has clear physiological advantages over mouth breathing, but current evidence for mouth taping as a sleep treatment is limited and uncertain.
- WeShutIt mouth tapes use ultra-thin bamboo fabric, hypoallergenic adhesive and optional hyaluronic acid to create a soft, flexible tape that feels like a second skin.
- Affirmation-stamped tapes and bedtime ritual cards turn mouth taping into a playful self-care routine rather than a purely clinical tool.
- Johanna reports less dry mouth, fewer night-time wake-ups and improved sleep metrics when using the tape, while stressing that individual results will vary.
- Mouth taping is strongly discouraged for anyone who cannot easily breathe through their nose, or who has conditions such as sleep apnoea, asthma, adhesive allergies or significant respiratory issues.
“The real question isn’t simply, does mouth taping work? It’s who might it work for? What can we reasonably expect? And who should avoid it altogether?”
Curious about how others tweak their routines to sleep better without getting sucked into wellness hype? This PureJo: Hack or Hype episode follows holistic health and wellness coach Johanna Langoy as she road-tests a very unusual product: hyaluronic acid-infused affirmation mouth tape from brand WeShutIt. You’ll hear Johanna’s trademark mix of geeky science chat and straight-talking product review.
She walks through why nasal breathing matters, explaining how “your nose actually has a very clever job to do before the air reaches your lungs,” and why mouth breathing has been linked with dry mouth, dental issues and snoring. She also flags the limits of current research, stressing that nasal breathing studies aren’t the same as proof that taping your mouth shut fixes sleep problems.
The heart of the episode is Johanna’s conversation with WeShutIt founder and CEO, breathwork coach and ex-finance professional, Pei Chan. Pei shares how years of chronic stress, snoring and mouth breathing led her to mouth tape, and why she swapped cheap surgical tape for designing bamboo-based, razor-thin strips that “feel like a second skin”. She talks materials, hypoallergenic adhesive, hyaluronic acid, and why she wanted tapes that don’t “rip the top layer” off your lips.
There’s plenty here for sceptics: Johanna openly questions safety, price and who should absolutely avoid mouth taping. She reviews how the tape actually feels, whether it stays on, what happens to her sleep metrics, and why she still calls this a “definite hack when it comes to quality” while warning it’s hype or worse for anyone who can’t safely breathe through their nose.
If you’re tempted by wellness trends but prefer honest testing over glossy promises, this episode gives you a detailed, no-nonsense look at whether bedtime mouth tape might be worth your money – or best left alone. Would you tape your mouth shut for better sleep?
