Nasal Tape. Does It Actually Work?
Everyone's talking about nasal tape. But does the science actually back it up? We looked into the research - and the honest answer is more nuanced than most brands will tell you. Some studies suggest real benefits around oxygen efficiency, sleep quality and nervous system regulation. Others aren't so convinced, particularly when it comes to high intensity performance. Here's what we know so far, and who it's likely to help most.
Nasal tape is having a moment.
Walk into any serious gym and you'll spot at least one person with a small strip of tape across the bridge of their nose. It's showing up in powerlifting meets, CrossFit boxes, running tracks and bedroom workouts alike. But is it actually doing anything - or is it just the latest fitness trend dressed up in performance clothing?
We looked into the research. And the honest answer is more nuanced than most brands will tell you.
What Is Nasal Tape and What Is It Supposed to Do?
Nasal tape is a small adhesive strip worn across the bridge of the nose. The idea is simple - by gently lifting the sides of the nasal passages, it reduces resistance in the airway and encourages nasal breathing over mouth breathing during exercise, sleep and everyday activity.
The broader argument for nasal breathing goes back decades, with researchers and breathing experts pointing to a range of potential benefits over mouth breathing. Nasal tape is essentially a tool designed to make nasal breathing easier and more consistent.
What the Research Says About Nasal Tape and Nasal Breathing
This is where it gets interesting.
The case for nasal tape and nasal breathing
Several studies have found meaningful benefits associated with nasal breathing in general. Research has linked nasal breathing to:
- Improved oxygen efficiency during sub-maximal exercise
- Better regulation of the nervous system and lower cortisol levels
- Increased nitric oxide production, which helps dilate blood vessels and improve circulation
- Lower heart rate during lower intensity training
A number of studies on athletes who trained exclusively through nasal breathing over several months reported improvements in endurance performance and recovery. Sleep is another area where the evidence is stronger - mouth breathing during sleep is associated with poorer sleep quality, increased snoring and higher cortisol levels.
Nasal tape worn at night has shown promise in several small studies as a simple, non-invasive intervention for reducing mouth breathing during sleep.
The case against nasal tape
Other studies paint a less clear picture. Several controlled trials found no statistically significant difference in performance between nasal and mouth breathers during high intensity exercise. The reason is fairly straightforward - at near maximal effort, your body will almost always override nasal breathing instinctively to get air in as fast as possible. Tape or no tape.
Some researchers have also pointed out that many of the studies supporting nasal breathing benefits are small in scale, short in duration or lack proper control groups. The science is promising but not yet conclusive.
What Most Experts Agree On
Despite the conflicting data on performance, there is reasonable consensus around a few key points.
Nasal breathing at rest, during sleep and during lower to moderate intensity exercise appears to be genuinely beneficial for most people. It:
- Filters and humidifies air before it reaches the lungs
- Activates the diaphragm more effectively than mouth breathing
- Helps regulate CO2 tolerance over time
- Keeps the nervous system in a calmer, more controlled state during training
Whether nasal tape is the intervention that gets you there is a separate question — and one that may depend heavily on the individual.
Who Is Nasal Tape Actually For?
Based on the available evidence, nasal tape is likely most beneficial for:
- People who are habitual mouth breathers and want to retrain their breathing patterns
- Athletes working on breathing mechanics during low to moderate intensity training
- Anyone who mouth breathes during sleep and wants a simple, non-invasive solution
- Lifters who want heightened proprioceptive awareness of their breathing during sessions
It is less likely to make a meaningful difference during genuinely maximal efforts - a heavy deadlift single, a sprint finish or a high intensity interval - where your body's demand for air will override any mechanical support.
Our Honest Take
We make Mammal Nasal Tape. So you might expect us to tell you it's a game changer and leave it at that.
We'd rather be straight with you.
The research on nasal breathing is genuinely interesting and increasingly well supported. The research specifically on nasal tape as a performance tool is still developing. What we know is that a significant number of our customers notice a difference - in their training, in their recovery and in their sleep. Many of them stick with it long term.
Whether you'll be one of them is something only you can find out. Your anatomy, your breathing habits and how you respond to the change all play a role.
Our suggestion - try it consistently for two weeks. Use it during your easier sessions and wear it at night. Pay attention to how you feel. Then make your own call.
That's all we'd ask.
