Yes, nasal strips make a real difference for runners, particularly if you have any degree of nasal obstruction. An external nasal dilator works by mechanically widening the nasal valve, the narrowest point of your airway, allowing more air in with each breath. If your nasal passages are restricted at all whether from a deviated septum, mucosal swelling during effort, or just a naturally narrow nasal valve, a nasal strip can meaningfully reduce airflow resistance without any medication.
If your nose is completely clear already, the benefit is smaller. But for a significant number of runners, the nose is the limiting factor in nasal breathing, and strips directly address that.
Why Nasal Breathing Matters for Runners
Breathing through your nose during a run does several things mouth breathing cannot. Your nose warms and humidifies incoming air, filters out particles, and produces nitric oxide, a gas that acts as a vasodilator and helps your lungs absorb oxygen more efficiently. None of that happens when you are breathing through your mouth.
Nasal breathing also naturally slows your respiratory rate. Instead of rapid, shallow mouth breaths, nose breathing encourages deeper, more controlled breaths. A lower respiratory rate at a given workload means lower perceived effort, better CO2 tolerance, and a delay in the feeling of breathlessness. For distance runners, that compounding effect matters on every long run.
The problem is that if your nasal passages are compromised, nasal breathing during exercise feels like trying to pull air through a narrow tube. Your nose becomes the bottleneck rather than the pathway, and most people default to mouth breathing to compensate. That is exactly where nasal strips help.
What a Nasal Strip Actually Does
An external nasal dilator is a spring tensioned adhesive strip applied across the widest part of the nose. As the strip tries to return to its flat shape, it lifts the sides of the nose outward, widening both the internal and external nasal valves. This reduces aerodynamic resistance in the nasal passages without any drug involvement.
For runners, the practical benefits are:
- Reduced airflow resistance at the nasal valve
- Less effort required to maintain nasal breathing during moderate intensity running
- Reduced crossover to mouth breathing at easier training paces
- Less nasal congestion from exercise induced mucosal swelling
There is also a comfort dimension that does not show up in studies. If your nose is partially blocked and you try to force air through it during a run, the sensation is rough and distracting. Opening the nasal valve even slightly changes the entire experience of breathing during effort.
My Experience Running with a Deviated Septum
I played rugby for over a decade, and my nose took a fair number of direct impacts over those years. By the time I finally went to see a specialist, the picture was pretty clear. My septum had deviated enough that one nasal passage was significantly narrower than the other, and running made the problem dramatically worse because of how exercise induced sympathetic stimulation affects nasal tissue.
An ENT referred me to a Consultant Otolaryngologist at a private hospital in Dublin. The recommendation was septorhinoplasty to correct the structural deviation. The procedure is listed under code 5975, it is not a quick recovery, and I was not ready to stop playing rugby for the weeks it would require. So I deferred the operation.
Running with a badly deviated septum is genuinely discouraging. Even easy aerobic runs felt laboured because I was defaulting to mouth breathing almost immediately. My respiratory rate would climb faster than it should, and everything felt harder. I was fit enough but could not access the breathing efficiency I should have had at easy pace.
Developing Ventriq came directly out of that frustration. I tried a lot of products and found most of them either did not open the valve enough or would not stay on through a run. Once I had a strip that actually worked, running became considerably more comfortable. I wear the Ventriq Sport Nasal Strip on every run now. Even short easy ones. The difference in breathing comfort is consistent enough that I would not go without it.
I have written in more detail about this in the post on breathing through your nose during exercise, which covers the physiology side more thoroughly.
What the Research Shows
The evidence on external nasal dilators and exercise is reasonably consistent. Studies have measured reductions in nasal airflow resistance of around 25 to 30 percent in subjects wearing an external nasal dilator compared to baseline. That reduction is measurable through rhinomanometry and repeatable across different populations.
Whether that translates to a performance improvement depends on the individual. In runners without nasal restriction, the performance effect is modest. In runners who have meaningful nasal obstruction, removing that restriction has a more significant impact because you are eliminating a real bottleneck in the system.
Research has also shown that nasal breathing during submaximal exercise results in lower heart rate and respiratory rate at equivalent workloads compared to mouth breathing. Anything that makes it easier to sustain nasal breathing at easy and moderate paces carries those efficiency gains into the session. I covered the broader evidence on this in the post on whether nasal strips improve athletic performance.
When Nasal Strips Help Runners Most
In my experience and from what people who use Ventriq tell me, nasal strips make the biggest difference in these situations:
- Easy and steady state runs where staying in nasal breathing is the goal
- Cold weather running, where cold air causes more mucosal swelling and airway narrowing
- Morning runs, when the nasal cycle often leaves one nostril more congested than usual
- Runners with a deviated septum, enlarged turbinates, or any structural narrowing
- Runners prone to exercise induced nasal congestion or a runny nose during effort
At maximal effort during a sprint or race finish, you are going to be mouth breathing regardless. Nasal strips are not going to change that. But for the bulk of your training volume, which happens well below threshold, they make it substantially easier to stay nasal.
Nasal Strips vs Other Options for Runners
The main alternatives are internal nasal dilators, decongestant sprays, and mouth tape. For running specifically, internal dilators are not comfortable during effort and tend to shift with movement. Mouth tape is obviously not for running. Decongestant sprays work acutely but are not drug free and carry the risk of rebound congestion with regular use, which makes them unsuitable for daily training.
External nasal strips are the most practical option for runners. They are drug free, there is no dependency risk, you can use one every day, and they stay on during a run if you apply them to clean dry skin before you start sweating. I have compared nasal strips to other breathing aids in detail in the post on nasal strips vs mouth tape.
Application is worth getting right. Apply the strip to your nose before you put your kit on, before any sweating starts. Press firmly for about 30 seconds. If an edge starts to lift during a run, pressing it back down briefly usually reseats it.
Which Nasal Strip Works Best for Running?
The Ventriq Sport Nasal Strip was built for this. The adhesive is stronger than standard sleep strips specifically to handle sweat and movement. The spring strength is calibrated for wider dilation, not just a gentle lift. I designed it because none of the products on the market gave me what I needed on a run.
If your main need is sleep rather than exercise, the Ventriq Sleep Nasal Strip is the right version. It is gentler and designed for stationary overnight use. For running and sport, go with the Sport version.
Nasal strips are not a cure for a deviated septum. I will still probably need surgery eventually. But they make training comfortable enough in the meantime that I can keep running and keep playing, and that is exactly why I built them in the first place.
Frequently Asked Questions
Do nasal strips actually help with running?
Yes, particularly if you have any nasal obstruction. They widen the nasal valve mechanically, reducing airflow resistance and making it easier to maintain nasal breathing during moderate training paces. The benefit is most noticeable in runners whose nasal passages are partially restricted.
Can I wear a nasal strip during a race?
Yes. There are no rules against external nasal strips in running events. They are drug free and contain no banned substances. Many recreational runners wear them in competition without issue.
Will a nasal strip stay on when I sweat?
If applied to clean, dry skin before sweating begins, yes. Press the strip firmly for 30 seconds after applying to maximise adhesion. The Ventriq Sport strip uses a stronger adhesive than standard strips specifically to handle exercise conditions.
Does running with a deviated septum get easier with nasal strips?
For most people, yes. A deviated septum narrows one nasal passage, which makes nasal breathing during exercise feel laboured. Widening the external nasal valve compensates partially for the internal structural narrowing. It does not correct the underlying deviation, but it makes training considerably more comfortable. You can read more about managing this in the post on sleeping and breathing with a deviated septum.
Should I use a nasal strip on every run or just hard sessions?
I use one on every run. The benefit is most noticeable on easy runs where staying in nasal breathing is the point, but there is no downside to wearing one on harder sessions either. Over time, consistently maintaining nasal breathing at easy paces builds CO2 tolerance and respiratory efficiency that carries over into faster work.
Are nasal strips better than nasal sprays for runners?
For regular training use, yes. Decongestant sprays cannot be used daily without risking rebound congestion, which makes them unsuitable for frequent running. Nasal strips are drug free, carry no dependency risk, and can be used every day. The only situation where a spray might be preferable is acute congestion from illness, where the obstruction goes beyond what a strip can address alone. I looked at this comparison in more detail in the post on best nasal strips for deviated septum.
