Why Mouth-Taping at Night Might Be Riskier Than You Think: What Women 30+ Need to Know
The Viral Sleep Hack That’s Raising Eyebrows—and Health Concerns
If you’ve spent even a few minutes scrolling through TikTok or Instagram lately, chances are you’ve seen influencers recommending mouth-taping before bed. The idea? That by sealing your mouth shut with a strip of tape, you’ll train your body to breathe through your nose, sleep deeper, and wake up more refreshed.
It sounds simple—and even kind of genius. But a new systematic review published in PLOS ONE is urging caution. According to the research, there’s no solid evidence that this trend is safe or effective—and in fact, it may even cause harm. For women navigating sleep challenges, stress, and hormonal shifts in their 30s to 50s, it’s more important than ever to make informed decisions. Let’s take a closer look.
What the Study Says: Mouth-Taping Isn’t the Miracle It Claims to Be
The PLOS ONE review analyzed 86 research papers on mouth-taping and chin straps. Here’s what they found:
- Only 10 studies met quality standards to be included in the final analysis.
- Of those, just one was a randomized controlled trial—the gold standard of scientific research.
- Across all studies, only 233 people were involved in total.
- The research was too varied and small-scale to draw meaningful conclusions or perform a meta-analysis.
Bottom line? There’s insufficient evidence that mouth-taping improves sleep or reduces snoring. Even more troubling: the potential for side effects.
The Health Risks: Why Experts Are Sounding the Alarm
Mouth-taping might sound harmless, but the potential risks are serious—especially for women who may already be dealing with nasal congestion from allergies, hormonal shifts, or sinus issues. According to the study and expert commentary, these are the top dangers:
1. Asphyxiation Risk
If your nose becomes blocked during the night (think congestion or deviated septum), you have no backup route for breathing. That’s a medical emergency waiting to happen.
2. Worsening Undiagnosed Sleep Apnea
Sleep apnea is often underdiagnosed in women, especially during perimenopause and menopause. Mouth-taping can exacerbate oxygen deprivation and lead to:
- Increased heart rate
- Elevated stress hormones
- Higher blood pressure
3. Skin and Lip Irritation
Facial skin is sensitive, and repeated taping can cause:
- Redness and chafing
- Allergic reactions to adhesives
- Dry, cracked lips
4. Choking Hazard
There’s a small but real risk that the tape could come loose and be inhaled or swallowed while you sleep.
The Science Behind the Study: What Makes the Evidence Weak
This wasn’t a one-off opinion piece. The authors of the PLOS ONE study performed a systematic review, which means they:
- Searched five major medical databases for studies on mouth-taping and chin straps.
- Applied strict quality filters to rule out biased or low-quality research.
- Found that most studies lacked control groups or used non-standardized measurements.
- Concluded that the research landscape was too “heterogeneous” to draw strong conclusions.
In other words, while the trend may feel trendy, the science simply doesn’t back it up yet.
A Safer, Smarter Approach: Acupressure Points to Support Nasal Breathing and Sleep
Instead of taping your mouth shut, consider this holistic, low-risk method from Traditional Chinese Medicine: acupressure. These specific points help promote nasal airflow and support deep relaxation, without interfering with your body’s natural sleep rhythms.
LI 20 (Welcome Fragrance) – Open the Nasal Passages
How to Locate LI 20: Place your fingertips on the outer edges of your nostrils, in the slight depressions where your nose meets your cheeks.
How to Use: Apply gentle pressure with both index fingers for 1–2 minutes while breathing deeply through the nose.
Benefits: This point helps clear nasal congestion and supports unobstructed airflow—especially helpful if you wake up stuffy.
GV 23 (Upper Star) – Calm the Mind and Support Sinus Function
How to Locate GV 23: This point is located on the midline of the forehead, approximately one inch behind the hairline.
How to Use: Use your middle finger to gently press and massage this point in a circular motion for 1–2 minutes before bed.
Benefits: GV 23 helps calm mental chatter and can ease sinus-related discomfort, making it easier to breathe and relax.
GB 14 (Yang White) – Relieve Tension and Clear the Head
How to Locate GB 14: Located above the center of each eyebrow, about one finger-width above the brow line.
How to Use: Use both index fingers to apply light pressure or massage the area in small circles for 1 minute.
Benefits: This point is used to release tension from the forehead and clear sinus congestion—ideal for women who experience facial tightness or seasonal allergies at night.
