Does nose breathing get easier with practice?

Nose breathing does get easier for most people with practice. The habit becomes more automatic with repetition, and your nose opens up a little during and after exercise, so breathing through it starts to feel normal rather than effortful. What practice can't do is fix a nose that's narrowed by its structure. If yours feels blocked most of the time, that's a reason to see a doctor, not to try harder.

Does nose breathing get easier?

Nose breathing gets easier for most people because two things improve with practice: the habit itself and your comfort with the slightly higher effort of breathing through a smaller airway. The research here is limited. No study has followed people as they switch from habitual mouth breathing to nose breathing at rest and measured how quickly it gets easier.

What the research does show helps explain the experience. Your nose isn't a fixed tube. A 1977 study that measured nasal resistance for up to 7 hours found cyclic changes in the resistance of each nostril in 13 of 24 experiments, and that total resistance dropped after exercise. That's why one side can feel blocked and later clear, and why breathing through your nose often feels easier after a walk.

There's also good evidence that people can choose to breathe through the nose more than they might expect. A 2022 review of breathing strategies for runners says studies have shown "surprising flexibility in airway choice during exercise". It notes that nose breathing during exercise requires some adaptation, and that the ideal approach still needs more research.

What changes as you practice?

Several things change as you practice nose breathing, and they happen on different timescales. Some are immediate, some take weeks, and some don't change at all.

The habit becomes automatic

Habit is the biggest piece for most people. If you've breathed through your mouth for years, closing it takes conscious effort at first. A 2024 meta-analysis of 20 studies on health habits found that, in the studies reporting timings, the median time to reach automaticity ranged from 59 to 66 days, with individual times from 4 to 335 days. None of those studies looked at breathing, but they give a fair sense of how long a new routine takes to stick.

Exercise opens the nose for a while

Exercise lowers nasal resistance in the short term. The 1977 study found total nasal resistance dropped after cycling, and the size of the drop was directly related to how hard people worked. So nose breathing during and just after a walk or easy run often feels easier than sitting still. Our guide to nasal breathing during exercise covers how to build it into training.

Your baseline nose stays about the same

Regular training doesn't seem to change the nose itself. A 2000 study compared 16 endurance athletes with 15 sedentary people and found their resting nasal resistance was the same, for both the structural and the lining-related parts of resistance. So practice changes how you breathe and how comfortable it feels, more than it changes the shape of your airway.

Congestion comes and goes

Swelling in the nasal lining from colds and allergies changes from week to week. A stuffy month can make nose breathing feel harder even when your habit is strong. Lying down adds to this. A 2021 meta-analysis found that lying down increases nasal resistance and reduces airflow, which is one reason nighttime is often harder than daytime. Our article on why your nose is stuffy at night explains more.

Why does nose breathing feel harder at first?

Nose breathing feels harder at first because the nose is a narrower path than the mouth, so each breath meets more resistance. If you're used to breathing through your mouth, that extra resistance can feel like you aren't getting enough air, even when you are. That feeling usually fades as you get used to it.

The body also has a natural switch point. The 2022 review notes that people generally switch from nose to mouth breathing once their breathing rate passes about 40 liters a minute, which happens as exercise gets harder. The 1999 study found the same pattern during progressive exercise: people breathed through the nose alone until effort climbed, then moved to nose and mouth together. So nose breathing is easiest at rest and at gentle effort, and that's the place to build the habit before you ask more of it.

What's a realistic timeline?

A realistic timeline is weeks to a few months, with a lot of variation between people. Because no study has measured this directly for everyday nose breathing, the table below combines what related research suggests with what you can check for yourself.

Treat these as rough guides, not deadlines. The habit research found some people formed habits in days and others took most of a year. Our article on whether you can train yourself to nose breathe goes further into the habit side.

How can you improve nasal breathing?

You can improve nasal breathing by clearing what's in the way and then practicing in the easiest situations first. A simple plan:

• Start with calm moments. Read, work or watch TV with your lips closed and breathe through your nose.
• Add easy movement. Walks and gentle runs are where nose breathing is most achievable, and exercise lowers nasal resistance as you go.
• Back off when you need to. A small 1999 study showed people naturally switch from nose-only to nose-and-mouth breathing as effort rises. That's normal, not failure.
• Deal with congestion. Treat allergies or a cold rather than pushing through a blocked nose.
• Make nights easier. Lying down increases nasal resistance, so a strip can help at bedtime.

That small 1999 study also found nasal strips lowered nasal resistance and let people keep breathing through the nose about 15% longer during exercise. Cleveland Clinic says breathing strips lift the skin and open the nostrils, and may help you breathe easier and sleep better at night. Our list of nasal breathing tips and the nasal breathing exercises guide have more ideas.

Where mouth tape fits

Some adults use mouth tape at night to help keep their lips together once nose breathing during the day feels comfortable. Only use it if you can breathe easily through your nose with your mouth closed. Cleveland Clinic says never to use mouth tape if you have nasal obstruction, nasal congestion, chronic allergies, a sinus infection or a deviated septum. Practice wearing it while you're awake first, and take it off if you feel anxious or short of air. Our guide on how to start mouth taping walks through a gentle first week. We don't recommend mouth tape for children.

When doesn't nose breathing get easier?

Nose breathing doesn't get easier when something physical is narrowing your airway. Cleveland Clinic says most people who mouth breathe do so because they can't get air in through the nose, and lists causes including a deviated septum, enlarged turbinates, and allergies, infections or irritation that make the turbinates swell. In children, enlarged adenoids or tonsils can block the airway. Cleveland Clinic says treatment means a healthcare provider treating the condition that makes nose breathing hard, with medication or sometimes surgery.

Nasal valve collapse is another structural cause. Cleveland Clinic says trouble breathing from nasal valve collapse may get worse during physical activity or when lying down. Breathing strips can help manage the symptoms, but many people need surgery, especially if they have other structural issues like a deviated septum.

See a doctor if:

• one or both sides of your nose feel blocked most days for weeks
• nose breathing hasn't become any easier after a couple of months of steady practice
• your nostrils visibly collapse inward when you breathe in
• you snore loudly or think you might have sleep apnea
• your child breathes through their mouth most of the time

Our articles on deviated septum symptoms and turbinate hypertrophy explain what an ENT doctor will look for.

Our pick (paid partner): Titan Sleep System

If you want help with nose breathing at night, our pick is the Titan Sleep System. It's our recommendation, not the result of testing or ranking products ourselves.

Titan says the system pairs TitanAir Nasal Strips and Titan Bamboo Silk Mouth Tape as one nightly routine. Titan describes the strips as drug-free external nasal dilators with flexible, spring-loaded bands, placed just above the flare of the nostrils on the soft part of the nose. It describes the tape as a bamboo silk strip worn horizontally across the lips, and suggests 20 to 30 minutes of daytime practice before the first night, which fits the gradual approach above. Titan says both are third-party tested and certified PFAS-free, with a 30-night guarantee.
