Does mouth tape actually work for snoring?

Yes. In a clinical study conducted by SleepSpace, participants using Hostage Tape reported 78.9% lower snoring by Week 3. The study used a single-blind, active-control design with breathing exercises as the comparator.

Is there clinical evidence that mouth tape improves sleep quality?

Yes. 84.6% of participants in the SleepSpace clinical study reported improved sleep quality with mouth tape. Participants also rated sleep depth 45.4% higher compared to no tape.

Who conducted the Hostage Tape clinical study?

The study was conducted by SleepSpace, led by Dr. Dan Gartenberg, a sleep scientist specializing in sleep technology and clinical research. The study used validated clinical measurement scales used in published sleep research.

The Science Behind Mouth Tape: Clinically Studied to Reduce Snoring & Improve Sleep

In a SleepSpace-run clinical study led by Dr. Dan Gartenberg, Hostage Tape users reported clinically meaningful improvements in sleepiness, sleep quality, and snoring in just 3 weeks.

How the Mouth Tape Sleep Study Was Conducted

This wasn't a survey. It was a structured, single-blind active-control clinical study run by SleepSpace and Dr. Dan Gartenberg, using validated clinical measurement scales—the same tools used in published sleep research.

Participants used Hostage Tape for three weeks under a guided protocol. The active comparator was breathing exercises, a credible behavioral intervention, not a placebo.

Both results were statistically significant (p < .001). Two independent clinical instruments agreed which makes the finding more credible than a single measure alone.

Key Findings: How Mouth Tape Improved Sleep

Finding 1 Snoring 78.9% lower snoring by Week 3

The most mechanism-specific result in the study. Participants who used Hostage Tape reported dramatically less struggle with snoring directly tied to the product's core function of keeping the mouth closed during sleep.

Finding 2 Sleep Quality 84.6% reported improved sleep quality

The clearest consumer-friendly signal in the study. Nearly 9 in 10 participants said their sleep quality improved with mouth tape.

Finding 3 Sleep Depth 45.4% higher sleep-depth ratings

Participants rated how deeply they slept significantly higher with mouth tape compared to no tape and no breathing exercises a strong signal for the high-performer and executive audience.

Finding 5 Dry Mouth & Mouth Breathing 69.7% lower dry-mouth frequency. 70.5% lower mouth-breathing frequency.

The mechanism is working. Participants reported dramatically less dry mouth and less mouth breathing at night the two most direct indicators that the tape is doing its job.

Real Mouth Tape Reviews From Study Participants

"Best mouth tape I have ever used, stayed on, helped with sleep."

"If I had to choose which improved my sleep quality more, the Hostage Tape was the clear winner."

"The tape helped minimize snoring and when I did snore, it was less loud."

"Mouth tape helped me to not wake as much during the night and my partner hardly ever noticed snoring."

"My experience with mouth tape has been very positive. I honestly feel like I cannot sleep without it now."

"I loved the mouth tape. I was definitely hesitant at first because I did not understand it nor had ever used it before but it worked. I will be using it nightly from now on."

Published Research on Mouth Taping for Sleep

A brief, plain-English summary of the existing peer-reviewed literature that supports the mechanism.

A 2025 scoping review (Fangmeyer et al.) screened 177 studies and identified 9 directly evaluating nocturnal mouth taping the evidence base is early but growing.
A 2022 study (Lee et al.) found that mouth taping in mouth-breathing adults with mild OSA reduced median AHI from 8.3 to 4.7 events per hour.
A 2025 RCT (Zaliene et al.) found that the mouth-taping group uniquely improved high-frequency HRV and breath-hold performance compared to breathing exercises alone.
The mechanism is well-established: nasal breathing supports nitric oxide production, humidification, and oxygen delivery. Mouth breathing bypasses all three.

These published studies were conducted independently and do not constitute an endorsement of Hostage Tape. Hostage Tape is not a medical device and is not intended to treat, cure, or diagnose any medical condition.

Not suitable for use with severe nasal obstruction, congestion, or respiratory conditions. Individual results may vary.
