Breathing through your nose while running might seem like a minor detail, but it can make a world of difference to your performance, recovery, and overall running experience. Many runners automatically breathe through their mouth, especially during intense exertion. However, increasing research and experience show that nose breathing during running offers clear benefits. In this blog, you'll discover why, how it works, and how to put it into practice.
What is nose breathing and why is it important?
Nose breathing simply means inhaling (and preferably exhaling) through your nose instead of your mouth. During running, this is more challenging than it sounds, as your body needs oxygen faster. Nevertheless, breathing through the nose has surprisingly many benefits that contribute to better performance through breathing.
With nose breathing:
- The air is filtered, warmed, and humidified
- You activate your diaphragm better
- You lower your heart rate and stress response
- You promote a healthy breathing pattern
Research even shows that well-trained runners with nose breathing can achieve up to 85% of their maximum exertion without immediate performance loss (Thomas et al., 2020) Nose breathing is therefore not only suitable for easy runs but can also be used for more intensive training.
7 benefits of nose breathing during running
1. Better oxygen uptake during exercise
With nose breathing, air stays in the lungs longer, which improves oxygen uptake and endurance. Research shows that runners using nose breathing achieve the same performance as with mouth breathing, but with less respiratory effort and more efficient oxygen use (McClaran et al., 2017)
2. Lower risk of hyperventilation
Mouth breathing can lead to shallow and rapid breathing. By breathing through your nose, you slow down your breathing and prevent unnecessary stress on your lungs.
3. More focus and calm in your body
Nose breathing activates the parasympathetic nervous system: the part that promotes relaxation. You remain mentally calmer, even when your pace increases.
4. Better control over pace and effort
Because you control your breathing better, you can consciously manage your training pace. It prevents you from starting too fast and giving up prematurely.
5. Lower risk of dehydration
With mouth breathing, you lose fluids faster. Nose breathing maintains better humidity in your airways, which is an advantage especially during long runs or hot weather.
6. Stronger respiratory muscles
Running with a closed mouth demands more from your respiratory muscles. This unconsciously trains your lung capacity and muscle strength.
7. Protection against air pollution and allergens
When running in urban or polluted areas, you can inhale harmful substances. The nose acts as a natural filter and limits the uptake of fine dust particles, allergens, and pollutants. Research shows that nose breathing can reduce the impact of air pollution on the airways (AydΔ±n et al., 2014).
Nose breathing vs. mouth breathing: the differences
| Feature | Nose breathing | Mouth breathing |
|---|---|---|
| Oxygen uptake | More efficient | Less efficient |
| Breathing rhythm | Calmer, deeper | Faster, shallower |
| Muscle tension | Lower | Higher |
| Risk of dehydration | Lower | Higher |
| Air filtration | Yes | No |
The conclusion: running with a closed mouth is healthier and more effective in the long run.

How do you learn to run with a closed mouth?
For many people, it takes getting used to not breathing through their mouth while running. Here are some tips to learn it:
Start slowly
Begin with a gentle jog or walk and breathe entirely through your nose. Only increase intensity as your body gets used to it.
Practice breathing rhythms
For example, try:
-
3 steps inhaling, 3 steps exhaling
-
Later: 4-4 or even 5-5 (as your lung capacity increases)
Combine with breathing exercises
Practice deep belly breathing and breathing exercises such as box breathing or the Buteyko method daily.
Tip: Pay attention to nasal congestion
A stuffy nose makes nose breathing difficult. Ensure open airways; more on that below.
Support with nasal strips: PurelyGoods as a tool
Many runners initially experience difficulty with nose breathing due to restricted airflow. Especially with colds, allergies, or narrow nasal passages, this can be frustrating.
The solution: nasal strips for sports
Nasal strips mechanically open your nostrils, allowing you to breathe more freely. This reduces the urge to breathe through your mouth and makes it easier to maintain your rhythm.
PurelyGoods nasal strips are specially designed for athletes:
- Hypoallergenic & skin-friendly
- Extra strong adhesive power (even when sweating)
- Discreet and comfortable during movement
- Ideal for daily use or intensive training

Frequently Asked Questions
Is nose breathing always better during running?
For low to moderate exertion: yes. During very intense sprints, your body might demand extra oxygen through your mouth. But training for nose breathing will ultimately increase your intensity tolerance as well.
What if my nose is always blocked?
Use a saline solution or consider an allergy check. Nasal strips can provide temporary relief.
How long does it take to get used to it?
On average, 2 to 4 weeks. Start with gentle runs and gradually build up.
Conclusion: natural breathing, better performance
Nose breathing during running might seem like a small adjustment, but its impact on your performance, recovery, and breathing is significant. You:
- Get more out of your oxygen uptake
- Run more calmly and controlled
- Reduce symptoms such as hyperventilation or fatigue
By consciously choosing to run with a closed mouth, you give yourself an advantage, without expensive gadgets or supplements. And with simple aids like nasal strips for sports, you make it even easier for yourself.
