The Science Is In. Mouth Tape Works.

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

78.9%

Lower Snoring Struggle

Participants reported 78.9% lower struggle with snoring by Week 3

84.6%

Improved Sleep Quality

84.6% of final study participants reported improved sleep quality with mouth tape

45.4%

Higher Sleep-Depth Ratings

Participants rated sleep depth 45.4% higher with mouth tape vs. no tape

3.7 pts

Epworth Sleepiness Reduction

A 3.7-point reduction in the Epworth Sleepiness Scale — exceeding the clinically meaningful-change benchmark of 2-3 points

How the Study Was Conducted

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

Participants used Hostage Tape for three weeks under a guided protocol. Sleep outcomes were measured using the Epworth Sleepiness Scale and the PROMIS Sleep Disturbance scale — two of the most widely used validated instruments in sleep medicine. The active comparator was breathing exercises, a credible behavioral intervention, not a placebo.

By Week 3, participants showed a 3.7-point Epworth improvement (exceeding the 2–3 point clinically meaningful-change benchmark) and a 6.8-point PROMIS improvement (exceeding the >5 point clinically significant-change benchmark).

What Participants Experienced

Finding 1 — Snoring 78.9% lower struggle with 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 4 — Daytime Sleepiness 3.7-point Epworth improvement — clinically meaningful

The Epworth Sleepiness Scale is a validated clinical instrument. A 2–3 point change is considered clinically meaningful. Participants exceeded that benchmark by Week 3.

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.

In Their Own Words

"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."

What the Published Research Says

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.
