The Benefits of Working Out With Nasal Strips On

You train hard. You eat right. You track your macros. You take your pre-workout. But have you ever thought about how air gets into your body while you're lifting?

Most people default to mouth breathing during exercise — especially once intensity climbs. It feels natural. More air, faster. But research suggests that nasal breathing during training may offer performance advantages that mouth breathing doesn't — and a nasal strip is the simplest tool to make it happen.

Here's what happens when you open your nasal passages during a workout and why athletes across every discipline are adding nasal strips to their gym bag.

What a Nasal Strip Does During Exercise

A nasal strip is an external adhesive strip with flexible spring-loaded bands. When applied across the bridge of the nose, the bands gently lift the nostrils outward and upward — physically widening the nasal passages and reducing airflow resistance.

The effect is immediate: more air flows through the nose with less effort. During exercise, when respiratory demand spikes and every breath matters, reducing nasal resistance can be the difference between smooth, controlled breathing and gasping through your mouth.

No drugs. No stimulants. No medication. Purely mechanical — the nasal equivalent of opening a window wider.

The Benefits of Nasal Breathing During Exercise

1. Nitric oxide production

Your paranasal sinuses produce nitric oxide exclusively during nasal breathing. Research published in the American Journal of Respiratory and Critical Care Medicine found that nitric oxide may dilate blood vessels in the lungs, potentially improving oxygen transfer from air to blood.

For anyone who's ever taken a pre-workout with L-arginine or L-citrulline — those supplements work by boosting nitric oxide production to increase vasodilation and blood flow to working muscles. Nasal breathing produces the same molecule naturally, with every breath, without supplementation. A nasal strip makes it easier to maintain nasal breathing at higher intensities where you'd normally switch to mouth breathing.

2. Improved oxygen efficiency

Nasal breathing is slower than mouth breathing. The resistance created by the nasal passages naturally slows airflow, which means each breath spends more time in the lungs — allowing more complete gas exchange in the alveoli.

Research suggests this slower, more efficient breathing pattern also retains more CO2 in the blood. Through the Bohr effect, adequate blood CO2 levels help hemoglobin release oxygen to muscles more effectively. The paradox of mouth breathing during exercise: you're moving more air, but your muscles may be receiving oxygen less efficiently.

A nasal strip reduces the resistance enough to make nasal breathing comfortable at moderate intensities — keeping you in the efficient breathing pattern longer before you're forced to switch to mouth breathing at peak effort.

3. Better CO2 tolerance

CO2 tolerance is the body's ability to function comfortably with elevated carbon dioxide levels — and it's one of the most trainable aspects of endurance fitness. Athletes with high CO2 tolerance breathe less frequently, stay calmer under exertion, and delay the gasping-for-air response that signals fatigue.

Training with nasal breathing — assisted by a nasal strip to keep the passages open — builds CO2 tolerance over time. The nasal passages create natural resistance that slows the rate of CO2 exhalation. Your body adapts to operating with slightly higher CO2 levels, and the threshold at which you feel "air hungry" rises.

This is why fighters like Sean O'Malley train nasal breathing — the ability to stay composed and breathe efficiently in round 5, when opponents are gasping, is a competitive advantage built during training.

4. Heart rate regulation

Research suggests nasal breathing is associated with parasympathetic nervous system activation — the calm, controlled state. Mouth breathing is associated with sympathetic activation — the panic response.

During exercise, this translates to better heart rate control. Nasal breathers tend to maintain lower heart rates at the same work output compared to mouth breathers. Lower heart rate at equal output means more cardiovascular headroom — you can push harder before hitting your ceiling.

A nasal strip makes nasal breathing accessible at intensities where you'd normally abandon it. By keeping the nasal passages open, it extends the intensity range where controlled nasal breathing is physically possible.

5. Reduced exercise-induced asthma symptoms

Exercise-induced bronchoconstriction (EIB) is triggered partly by cold, dry air hitting the bronchial tubes directly. Mouth breathing delivers air at ambient temperature and humidity. Nasal breathing warms and humidifies air before it reaches the lungs — potentially reducing the trigger for airway constriction during exercise.

Research published in the journal Respirology found that nasal breathing during exercise was associated with reduced bronchoconstriction compared to mouth breathing. For anyone who experiences tightness, wheezing, or coughing during or after workouts, a nasal strip that makes nasal breathing easier during exercise may be worth trying — in addition to any prescribed medications.

6. Better focus and composure

The parasympathetic activation associated with nasal breathing doesn't just affect heart rate — it affects mental state. Athletes who breathe through their nose during training describe feeling more composed, more present, and less reactive to discomfort.

This is especially relevant for sports requiring precision under fatigue: golf, martial arts, archery, shooting, and any strength sport where technique degrades as fatigue accumulates. Bodybuilders and strength athletes who maintain nasal breathing during working sets report better mind-muscle connection and more controlled reps.

Which Exercises Benefit Most From Nasal Strips

Strength training. During moderate-intensity sets (60-80% of max), nasal breathing is typically sustainable — and a nasal strip makes it comfortable. The controlled breathing pattern may improve bracing, intra-abdominal pressure, and mind-muscle connection. At maximal effort (heavy singles, AMRAPs), you'll likely switch to mouth breathing — and that's fine. The nasal strip still helps during warmup sets, accessory work, and rest periods.

Cardio (zone 2 and zone 3). Nasal breathing is ideal for steady-state cardio — running, cycling, rowing, swimming — at moderate intensities. A nasal strip keeps the passages open so you can maintain nasal breathing at higher heart rates before needing to mouth breathe. This is where CO2 tolerance training happens. Over weeks, you'll find you can maintain nasal breathing at progressively higher intensities.

Yoga and mobility work. Nasal breathing is foundational to yoga — pranayama (breath control) is entirely nasal. A nasal strip can help practitioners with mild nasal restriction maintain comfortable nasal breathing throughout a session without the distraction of restricted airflow.

HIIT and high-intensity intervals. At true high intensity, nasal breathing may not provide enough airflow to meet demand. This is normal and expected — your body needs the higher volume airflow that mouth breathing provides at maximal effort. The nasal strip still helps during recovery intervals between sets, when returning to nasal breathing quickly helps activate the parasympathetic response and accelerate heart rate recovery.

Walking and hiking. The lowest-intensity application — but possibly the most impactful for people new to nasal breathing. Training nasal breathing during walks builds the habit and CO2 tolerance that transfers to higher-intensity exercise over time.

How to Use Nasal Strips During Workouts

Application: Clean and dry the bridge of your nose. Center the strip over your nostrils. Press gently to secure. You should feel an immediate widening of the nasal passages.

Timing: Apply before your warmup. The strip should be on before you start — not mid-workout when your nose is sweaty and the adhesive won't stick as well.

During the workout: Breathe through your nose as long as you comfortably can. When intensity demands it, let yourself mouth breathe — don't fight it at maximal effort. During rest periods, return to nasal breathing immediately. The strip keeps the passages open so the transition back to nasal breathing is seamless.

After the workout: Keep the strip on during your cooldown. The post-workout period is when parasympathetic activation matters most for recovery initiation. Nasal breathing during cooldown may help lower heart rate faster and begin the recovery process sooner.

Nasal Strips for Training + Mouth Tape for Sleeping

The athletes getting the most from nasal breathing are using two tools for two different contexts:

Nasal strips during training — open the nasal passages to make nasal breathing accessible at higher intensities. Build CO2 tolerance. Improve oxygen efficiency. Maintain composure under exertion.

Mouth tape during sleep — close the mouth to ensure nasal breathing for 7-8 hours of recovery. Maximize deep sleep. Support growth hormone release. Eliminate snoring.

Together they create a 24-hour nasal breathing system — optimized breathing during training AND during recovery. The training builds the capacity. The sleep builds the adaptation. Both compound over time.

Erling Haaland tapes his mouth during sleep. Anton Ratushnyi uses nasal strips. Sean O'Malley does both. The trend across elite sport is clear: control how air enters the body — during training and during sleep — and the performance follows.

What to Look for in a Nasal Strip for Exercise

Strong adhesion. Sweat weakens adhesive bonds. The strip needs to hold through an hour of sweating without lifting at the edges. Apply to clean, dry skin before you start sweating — not after.

Flexible spring-loaded bands. The bands should maintain consistent outward pressure throughout the session. Cheap strips with weak bands lose their lift as the adhesive warms — providing less opening exactly when you need more.

Drug-free. Medicated nasal sprays cause rebound congestion with repeated use. Nasal strips work mechanically — no medication, no rebound, safe for daily use indefinitely.

Comfortable enough to forget. If the strip is distracting, it's counterproductive. You should feel the airflow improvement and forget the strip is there.
