Episode: Why are people taping their mouths?
Host: ABC News
Date: February 4, 2025

Overview

This episode delves into the surprising rise in popularity of mouth taping, a trend championed on social media for its supposed health benefits—particularly for sleep and breathing. Hosts (C and B, with Norman as B) respond to listener questions and anecdotes, investigate the scientific basis, and consider who might benefit (or be harmed) by taping their mouths at night.

Key Discussion Points & Insights

1. Public Curiosity & Experiences with Mouth Taping

• Mouth taping has become a widespread buzz on social media and among listeners, with people reporting personal benefits like reduced snoring and improved rest.
• Listener anecdotes:
  • Justin: Heard recommendations, wonders about safety and evidence.
  • Anna: Tried it, claims “snoring's cured, deeper restful sleep, no dry mouth.”
  • Nigel: Experimenting, using a sleep tracker; results “inconclusive so far, but I think I wake up less and feel more rested.”
    ([02:17]–[03:26])

2. Norman’s (Host B) Experience as a Mouth Breather

• Norman shares he’s an “obligate mouth breather” due to a childhood injury causing a deviated septum.
  Quote: “I got bashed up when I was a kid and broke my nose... Never got it set properly. I’ve got a deviated septum...” ([00:52])

• He only learned about mouth taping a few weeks before the episode and reluctantly tried it on-air as a personal experiment.

3. How Mouth Taping is Done

• Norman used basic medical tape, sealing his lips lengthwise for a “pretty good seal,” noting there are commercial alternatives designed for comfort. ([04:32]–[04:36])

4. Theoretical Background

• Mouth taping is connected (loosely) to the Buteyko Method (breathing retraining to promote nasal breathing via back pressure).

• The nose plays critical roles:

  • Filters pathogens/particulates and humidifies/warms incoming air.
  • Nasal breathing can theoretically prevent asthma or lessen symptoms, as unfiltered mouth breaths may irritate airways.
    ([05:45]–[07:21])

• Buteyko Method and mouth taping are not the same, but share foundational ideas. Quote: “The line between the Buteyko method and mouth taping could be seen to be a bit tenuous.” ([07:27])

5. Claimed Health Benefits

• Asthma: Weak evidence for direct benefit from mouth taping; more promising for Buteyko (which is more involved).
• Sleep Apnea & Snoring: Some preliminary studies indicate mouth taping may help—especially for severe cases.
  Quote: “The worse the snoring or apnoea was, the greater the benefit from mouth taping.” ([09:51])
• Sleep Quality & Bad Breath: Subjective improvement reported, but objective evidence is slim.
• Cardiovascular Health: Supposed mechanism is vagal nerve stimulation—but actual impact on heart health is unproven and speculative.
• Cosmetics/Face Shape: No evidence for overnight jawline transformation; long-term mouth breathing can subtly affect children’s facial structure, but not relevant for adults seeking cosmetic gains.
  ([12:51]–[14:09])

6. Scientific Evidence

• The evidence base is thin and mostly anecdotal with a handful of small or preliminary studies.
• More convincing research exists for reducing mild sleep disordered breathing by treating nasal obstruction without tape (e.g., nasal steroids, lavage).
• Safety concerns are minimal for most, but mouth taping is not advised for those with:
  • Sinus/ear infections
  • Difficulty breathing through nose (polyps, severe nasal deviations)
  • Obesity (risk of airway collapse)
  • Severe heart or lung diseases
  • Alcohol or sedative use (suppressed awakening reflex)
  • Sensitive skin (possible irritation from tape)
    ([14:30]–[15:14])

7. Norman’s Verdict (Personal Trial Results)

• Norman’s experience was overwhelmingly negative due to his nasal obstruction. Quote: “Completely bloody shite.” ([15:32])
  • He felt panicky, woke up exhausted—only lasted a couple of hours before pulling the tape off.
• Takeaway: The technique may work for others but is a poor fit for those struggling to breathe through the nose.

Notable Quotes & Memorable Moments

• On discovery of mouth taping:

  • C: “Get with the program. You’re obviously not on TikTok.” ([03:38])

• Norman’s caution:

  • B: “For you to recommend it or doctors to recommend it, you’d really want good evidence that it actually works and doesn’t do any harm. And there are a lot of claims being made for it.” ([03:43])

• C (on cosmetic claims):

  • “The people in them tend to be about 22 years old to start with. But also I just can’t… it just can’t be true.” ([12:51])

• On personal safety:

  • B: “If you’ve got an infection, an ear infection or a sinus infection, you shouldn’t tape your mouth... If you’ve consumed alcohol or sedatives... severe heart or lung problems... And then there’s the effect of the actual tape on your lips.” ([14:30])

• Norman after his test:

  • B: “I started to get panicky because I was having trouble breathing through the nose. But I got through an hour or two... eventually I had to sort of ease it off… woke up completely knackered.” ([15:32])

Summary / Takeaway

• Mouth taping is trending, with plenty of anecdotal support and passionate online testimonials, particularly for snoring and a “better night’s sleep.”
• Scientific evidence is limited and doesn’t robustly support wider claims (especially for asthma, heart health, or cosmetic changes).
• Safe for most, but not recommended for individuals with nasal obstructions, certain health conditions, or those under influence of depressants.
• If it works for you and is safe in your case—keep going! For those like Norman with nasal blockage, it’s uncomfortable and not worth the risk or distress.
• Always consult healthcare professionals before trying health trends when underlying conditions might be present.

Hosts end by inviting further questions and feedback from listeners, reminding all that mouth taping is not for everyone—and Norman won’t be trying it again!
