Why Health Pros Point To Nasal Breathing — And Where Nose Strips & Mouth Tape Fit In
Breathing through your nose is one of the most consistently recommended habits in respiratory and sleep health. Here's the science behind it, what nose strips and mouth tape each actually do — and how to use them safely (nose first).
You'll rarely find a doctor, dentist, physio or sleep clinician who tells you to breathe through your mouth. Nasal breathing filters, warms and humidifies air, adds airway-opening nitric oxide from your sinuses, and is simply more efficient — which is why it's the near-universal recommendation for better sleep, calmer breathing and healthier airways. Nose strips and mouth tape are two simple, drug-free tools that help you do it: a strip mechanically opens a narrow or stuffy nose, and mouth tape gently keeps your lips together so you don't slip back to mouth-breathing overnight. The golden rule is nose first — only tape the mouth once you can breathe comfortably through your nose.
Why nasal breathing is the one everyone recommends
Your nose isn't just a second-choice airway — it's a piece of biological air-conditioning your mouth can't replicate. Breathe in through it and the air is filtered by fine hairs and mucus, warmed and humidified before it reaches your lungs, and dosed with nitric oxide, a gas produced in your sinuses. That last part matters more than most people realise: nitric oxide helps widen the blood vessels in the lungs so you absorb oxygen more efficiently, and it has natural antimicrobial properties. Your mouth does none of this.
The knock-on effects are why the advice is so consistent across GPs, dentists, ENT specialists, sleep physicians and breathing coaches:
- Better oxygen uptake. Some research suggests nasal breathing improves oxygen exchange by roughly 10–20% compared with mouth breathing, partly thanks to nitric oxide and the slight back-pressure the nose creates.
- Cleaner, safer air. The nose traps dust, allergens and pathogens that an open mouth lets straight through.
- Calmer, more efficient breathing. Nasal breathing encourages slower, deeper breaths and builds tolerance to carbon dioxide — which is what makes breathing feel unhurried rather than air-hungry.
- Deeper, quieter sleep. Breathing through the nose is strongly linked to stopping snoring, no dry mouth and steadier, less disrupted sleep.
What mouth-breathing costs you
If nasal breathing is the recommendation, chronic mouth-breathing is the habit health professionals are trying to reverse. Sleeping with your mouth open dries out the mouth and throat, is a leading driver of snoring, and is associated with poorer sleep quality, more night-time waking, worse morning breath, and — over years — dental and gum problems from a dry oral environment. In children it's taken seriously enough that dentists and orthodontists actively screen for it. The daytime version isn't harmless either: habitual mouth-breathing tends to be shallower and faster, which can leave you feeling wired and less recovered.
The frustrating part is that many people mouth-breathe simply because their nose feels blocked or narrow — from allergies, a deviated septum, or a collapsing nasal valve — so the mouth becomes the path of least resistance. Fix the nose, and mouth-breathing often takes care of itself. That's exactly the gap these two products are designed to close.
Where nose strips fit: open the airway first
A nasal strip is a spring-like band that sits across the bridge of your nose and gently lifts the flexible walls of the nasal valve outward — the narrowest part of your airway. That mechanically widens the opening and drops the resistance you breathe against, so more air moves through the nose with less effort. Force Tape's Airflow+ black nose strips are built to open the airway up to 50% wider, using a sweat-proof ForceLock™ adhesive on breathable, plastic- and latex-free satin so they hold all night — and through a workout — without peeling.
Crucially, a strip is drug-free. Unlike a decongestant spray, there's no rebound congestion and nothing to build tolerance to, which is why it's an easy, low-risk first step: it makes nasal breathing physically easier so the healthy habit is actually achievable.
Where mouth tape fits — and what the evidence actually says
Mouth tape is the second half of the equation. A strip opens the nose; a small piece of tape (or a lip-centred patch) simply discourages your mouth from falling open while you sleep, nudging you to keep breathing through your nose all night. Many people use it alongside a nasal strip specifically to lock in the nasal-breathing habit.
Here's the honest picture on the research, because it matters. Mouth taping became a social-media trend well ahead of the evidence. A 2025 systematic review concluded the benefits are "modest and mostly limited to people with mild sleep-disordered breathing"(though in our own testing and thousands of customer results, we've found this can be false — used correctly, with the nose clear first, mouth tape helps far more people than that suggests). That said, it's still not a cure for snoring or sleep apnoea. More importantly, the same review flagged a genuine safety concern: taping the mouth shut when the nose is blocked, or when someone has undiagnosed obstructive sleep apnoea, can be risky. The takeaway isn't "don't" — it's "do it sensibly": make sure you can breathe freely through your nose first, start gently, and never tape over a congested nose.
Standard vs. collagen mouth tape
Force Tape makes two versions so you can match the tape to the job. The Recovery+ Mouth Tape is the straightforward, skin-safe option for encouraging nasal breathing and recovery overnight. The Collagen+ Mouth Tape adds a collagen-infused strip designed for people who want a little lip care while they build the habit. Both are gentle on skin and easy to remove — pick whichever you'll actually wear every night.
Two tools, one goal
Nose strips and mouth tape aren't competitors — they're a pair. The strip removes the mechanical reason you mouth-breathe (a narrow or stuffy nose); the tape removes the habit reason (your mouth drifting open in your sleep). Used together, they make nasal breathing the path of least resistance all night.
The order that matters: nose first, then mouth
- Clear and open the nose. Apply a nasal strip so your airway is genuinely open. If you're badly congested from a cold or allergies, deal with that first — a strip can help move heavier mucus once it's on, but you need to be able to breathe through your nose.
- Check you can breathe with your mouth closed. Sit for a minute breathing only through your nose, lips together. Comfortable? Good. Struggling? Stop here and stick with the strip alone.
- Add mouth tape gently. Once nasal breathing is easy, a small piece of mouth tape keeps your lips together so you don't revert overnight. Start with a night or two to get used to it.
- Build the habit. Over a few weeks, nasal breathing becomes your default — the tools become a top-up rather than a nightly necessity.

Why they're turning up on pharmacy shelves
For a long time nasal strips and mouth tape lived in the "wellness trend" bucket. That's changing. As the science on nasal breathing has become better understood, these drug-free aids are increasingly being stocked by pharmacies and chemists alongside the usual sleep and respiratory range — and Force Tape's nasal strips and mouth tape (standard and collagen) are now among them. It's a simple vote of confidence: pharmacists tend to stock what's safe, drug-free and genuinely useful to their customers, and a well-made strip or a gentle mouth tape ticks all three boxes.
It also reflects how people actually want to solve these problems: not with another medication, but with a low-risk, mechanical nudge toward the way the body is built to breathe.

Do doctors recommend nasal breathing?
Nasal breathing is very widely endorsed across GPs, dentists, ENT specialists, sleep physicians and breathing coaches, because the nose filters, warms and humidifies air and adds nitric oxide that helps you absorb oxygen more efficiently. Mouth-breathing, by contrast, is linked to snoring, dry mouth and poorer sleep. Nose strips and mouth tape are simple, drug-free tools that help you breathe through your nose — though mouth tape should only be used once your nose is clear.
Should I use a nose strip or mouth tape first?
Always the nose strip first. Its job is to open a narrow or stuffy nasal airway so nasal breathing is actually easy. Only once you can breathe comfortably through your nose with your lips together should you add mouth tape to keep the habit going overnight. Taping a blocked nose shut is exactly what you want to avoid.
Is mouth taping safe?
For most healthy people who can already breathe well through the nose, gentle mouth taping is low-risk. But a 2025 systematic review found the benefits are modest and mostly limited to mild cases, and it flagged a real risk of taping the mouth shut when the nose is blocked or when someone has undiagnosed sleep apnoea. Don't use mouth tape if you have (or suspect) sleep apnoea, heavy snoring, a blocked nose, or after alcohol or sedatives — see your GP first.
Can nose strips and mouth tape be used together?
Yes — that's the ideal combination for many people. The nasal strip mechanically opens the nose, and the mouth tape keeps your lips together so you don't drift back to mouth-breathing while asleep. The strip removes the mechanical reason you mouth-breathe; the tape removes the habit reason.
What's the difference between standard and collagen mouth tape?
Force Tape's Recovery+ Mouth Tape is the straightforward, skin-safe option for encouraging nasal breathing overnight. The Collagen+ Mouth Tape adds a collagen-infused strip for people who'd like a little lip care while they build the habit. Both are gentle and easy to remove — the best one is whichever you'll wear consistently.
Will these cure my snoring or sleep apnoea?
No — and it's important to be clear about that. Nose strips can reduce snoring that's driven by nasal blockage, and mouth tape can help mild mouth-breathing, but neither is a treatment for obstructive sleep apnoea. If you snore heavily, gasp or stop breathing in your sleep, or wake unrefreshed, see your GP or a sleep specialist for proper assessment.
