Nasal Breathing and Breathing Mechanics
Quick check before you read on. Is your mouth open right now? Is your breath high in your chest, or low in your belly? Fast, or slow?
Most of us never think about it. Yet we breathe thousands of times a day, and the way we do it can quietly shape how we feel.
What is it?
01This isn’t a breathing exercise you set aside time for. It’s about how you breathe the rest of the time: at your desk, on a walk, in the car, while you sleep.
It usually involves breathing through your nose, breathing low and slow rather than high in the chest, and noticing habits such as mouth breathing, frequent sighing or quick, shallow breaths when you’re concentrating.
Many contemplative traditions, including yoga, have long emphasised breathing through the nose. Modern research is starting to look at why.
What may it help with?
02People often explore their breathing habits when they notice their breath is shallow or fast, when they feel anxious or on edge for no clear reason, or when they have concerns about sleep, snoring or waking up tired.
Sometimes a breathing habit is one small piece of a bigger picture. Noticing it can be a gentle place to start.
How does it work?
03Think of your nose as your built-in air conditioner. It filters, warms and moistens the air before it reaches your lungs. Your mouth doesn’t do much of that.
Breathing through your nose also tends to slow the breath down naturally, because there’s a little more resistance. Slower breathing may support a calmer nervous system.
Researchers are also exploring how nasal breathing affects the brain. In a 2016 study, breathing through the nose was linked with rhythmic activity in brain areas involved in emotion and memory, and this faded when people breathed through their mouth [2].
What does the evidence say?
04The physical reasons for breathing through your nose are well understood, and research on the mind is growing.
A 2026 review brought together research on nasal breathing across development, the body, the immune system and emotions. It linked nasal breathing to stronger immune defence and to better emotion regulation [1].
It’s a free, gentle habit with good reasons behind it, and one you can start noticing today.
How to practise
05There’s nothing to schedule. Just check in with your breathing at a few points in your day:
- When you wake up: was your mouth dry? Did you breathe through your mouth overnight?
- At your desk: is your breath quiet and low, or high and quick? Are you holding it while you concentrate?
- On a walk: can you keep your mouth gently closed and breathe through your nose at an easy pace?
- When you exercise: notice when you switch to mouth breathing. There’s no need to force it.
- Before sleep: let your breath settle, slow and low into your belly.
Over time, these small check-ins can help nasal breathing become your default.
If you have ongoing breathing concerns, a physiotherapist with experience in breathing pattern disorders may be able to help.
Considerations
06A blocked nose has a reason. If you find it hard to breathe through your nose, it may be allergies, congestion or a structural issue, and it’s worth getting it checked.
Listen to your sleep. Loud snoring, pauses in your breathing during sleep, or waking up tired can be signs of sleep apnoea, which needs medical attention.
Questions to ask a practitioner
07- Is there a reason I find it hard to breathe through my nose?
- Would a sleep study help me?
- Could breathing retraining help me, and who could guide me?
