The Science Behind Better Breathing
Mouth breathing dries your mouth, disrupts oxygen balance, and activates stress responses that ruin deep sleep.
Hostage Tape retrains your body to breathe the way it was designed to, through your nose.
💨 More Oxygen
Nasal breathing increases nitric oxide, improving oxygen delivery to your brain and muscles.
🦷 Healthier Mouth
Keeping your mouth closed prevents dryness, cavities, and bad breath caused by overnight airflow.
😴 Deeper Rest
A calm, sealed mouth reduces vibration in the airway, less snoring, more restorative sleep.
From the Founder
“I was that guy, snoring loud, exhausted every morning, and sleeping in a different room from my wife.”
I tried everything gadgets and pillows but nothing worked because nothing was fixing the real problem: how we breathe.
So I built Hostage Tape. A simple, effective way to retrain your body to breathe naturally, quietly, and calmly through your nose.
Today, over 150,000 people use it every night, from athletes to tired parents, and it’s saving more than just sleep.
Top 10 Questions About Mouth Tape
What is Mouth Taping?
Mouth taping is a simple way to help your body do what it was designed to do, breathe through your nose while you sleep.
When your mouth stays closed, your tongue sits against the roof of your mouth, which helps keep your airway open and stable.
This position improves oxygen exchange in your lungs and reduces airway collapse, leading to deeper, quieter sleep and more consistent oxygen levels through the night.
Science behind it:
- Nasal breathing increases nitric oxide, which improves oxygen absorption in the bloodstream.
- Mouth breathing causes excess carbon dioxide loss, disrupting the body’s balance and sleep stability.
Is Mouth Taping Safe?
Yes, if you can breathe through your nose when lying down, it's safe to mouth tape.
If you can't breathe through your nose, don't.
You also want to use proper tape made for sleep.
Hostage Tape is medical-grade, breathable, and skin-safe. It’s designed to seal gently and be breathable, allowing your body’s natural reflexes to stay intact.
Science behind it:
- Human breathing reflexes are automatic; if nasal airflow drops, the brain triggers mouth opening or awakening.
What If My Nose Gets Stuffy or I Have Allergies?
If you can breathe through your nose during the day, you can usually tape safely at night.
Allergies or congestion can make nasal breathing harder, but nasal breathing itself improves sinus health by increasing airflow and nitric oxide production.
Use a saline rinse or nasal dilator if needed.
Science behind it:
- Nitric oxide has antimicrobial and anti-inflammatory effects that reduce swelling in nasal tissue.
- Consistent nasal airflow trains the nasal turbinates to stay open longer, improving long-term breathing capacity.
Could I Suffocate in My Sleep?
No. Your body has powerful safety reflexes that prevent that.
If your nasal passage becomes blocked, you will automatically open your mouth or wake up.
Hostage Tape is breathable and designed to peel off if needed.
Science behind it:
- The brain’s medulla oblongata monitors blood CO₂ levels and triggers arousal or mouth opening if oxygen levels fall.
- Research shows these protective reflexes activate long before oxygen levels reach danger zones.
Why Can't I Just Use Regular Tape?
Because regular tape isn’t made for skin or the dynamic movement of your lips.
Medical or athletic tape can irritate skin, pull hair, or trap heat and moisture especially for men with facial hair.
Those random Amazon brands often use industrial adhesives, non-sterile factories, and zero quality control.
No refund policy. No guarantee. No traceability.

“The cheap Amazon ones burned my skin. Hostage Tape just works.”
Why Does Nasal Breathing Matter so Much?
Your nose is a built-in air filter and oxygen optimizer.
When air passes through it, it’s cleaned, humidified, and warmed to protect the lungs.
Even more important, your sinuses release nitric oxide, which boosts oxygen transfer in your blood, supports cardiovascular health, and even helps fight bacteria and viruses.
Science behind it:
- Nitric oxide acts as a vasodilator, improving oxygen delivery to cells and tissues.
- Nasal breathing activates the parasympathetic nervous system, lowering stress hormones and heart rate.

Frequently Asked Questions
What Is Mouth Tape ?
Mouth tape is a simple sleep aid designed to gently keep your lips closed at night so you can breathe through your nose instead of your mouth. Nose breathing supports deeper rest, reduces snoring, improves oxygen intake, and helps prevent dry mouth. Unlike generic tape, Hostage Tape is specially made to be safe for skin, beard-friendly, and CPAP-compatible. Millions of people use mouth tape to stop snoring, sleep better, and wake up feeling more refreshed.
Is Selora Tape safe?
Yes. It's made with a skin-safe, medical-grade adhesive designed to stay on all night and remove comfortably in the morning.
Our bodies also have instincts that wake us up if breathing becomes uncomfortable due to congestion. It’s a lot smarter than we give it credit for! Mouth breathing causes the blood vessels in the nose to trigger mucus production and swelling; nasal breathing helps to combat that.
Selora Tape is also porous, so air can pass through if needed. If you’re hesitant, practice with the tape + nose strips during the day to get used to nasal breathing, then wear it all night when you can (nasally) breathe comfortably!
Will it work with my beard?
Yes. That’s what makes Selora Tape different. Our adhesive and flexible fabric holds through facial hair without failed seals.
Can I Mouth Tape With a CPAP? Yep!
Absolutely. Selora Tape is CPAP-friendly and stays out of the way of your mask while still preventing mouth leaks
What if I sleep with my mouth open?
That’s exactly what it’s for. SeloraTape stops mouth breathing so you wake up refreshed, not groggy or dried out.
By sealing your lips, you are forced to breathe through your nose. This promotes better, more peaceful sleep for both you and your partner
How is Selora Tape Better? You obviously haven’t tried it!
Selora Tape is the best mouth tape on the planet - full stop. Why? Because it’s a completely unique fabric, shape, adhesive, and experience. We’re stronger than other tapes, yet so comfortable most forget they’re wearing it. We’re made with medical grade, hypo-allergenic material and acrylic adhesive without latex. We’re porous, safe on skin, and strong enough for facial hair and strong jaws!
