Nasal Strips for Sports & Fitness

When you breathe through your nose, your body produces nitric oxide — a gas that opens blood vessels and helps oxygen reach your muscles more efficiently. Mouth breathing skips this entirely, meaning every mouth breath delivers less usable oxygen per litre of air. Over a long run or hard set, that difference compounds into real fatigue.

Studies show athletes who maintain nasal breathing during exercise experience lower heart rates, reduced perceived exertion, and better endurance. The challenge is that intense effort pushes most people to mouth-breathe — the airway simply can't keep up with demand, and the body defaults to the path of least resistance.

Cleeneo nasal strips solve this by mechanically widening the nasal valve. The spring-tension bar holds the passage open through your hardest efforts, so you can keep breathing through your nose when it matters most — on the run, in the gym, and on the bike. The wider airway means each nasal breath delivers more air, delaying the switch to mouth breathing.

Beyond performance, nasal breathing also aids recovery. It activates the parasympathetic nervous system, which lowers heart rate and helps your body return to a resting state faster between intervals. Many athletes use Cleeneo during cool-downs and post-workout breathing exercises for exactly this reason.

1. Apply before your warm-up. Clean and dry the bridge of your nose, then peel and press the strip firmly across the bridge. Applying it before you start sweating gives the adhesive the best surface to bond to.

2. Focus on nasal breathing. With the airway open, consciously breathe through your nose during your warm-up and build. You'll find it easier to sustain nasal breathing at higher intensities than you're used to.

3. Remove after your session. Gently peel from one side after you've cooled down. The adhesive releases cleanly even after heavy sweating.
