Your Breath Sets The Tone of Your Life – Make Sure You’re Breathing in a REAL Way
Most of us don’t really think about how we breathe – it just kinda…happens: inhale, exhale, repeat.
Here’s the wild part, though:
HOW you breathe – particularly whether it’s through your nose or mouth – can dramatically shape not just your health, but also your mind, emotions, and your ability to live a real, meaningful life.
That might sound like a disproportionate amount of power to give to two small holes in the middle of your face but bear with me:
By the end of this article, you’ll see why nose breathing is one of the most underrated keys to nervous system regulation and why that matters more than almost anything else when it comes to being healthy, real, and able to trust yourself and life to get where you need to be.
Let’s dig a little deeper:

The Forgotten Superpower Right Under Your Nose
Let’s start with a basic truth that many of us have never really given much thought to:
Your body is designed to breathe through your nose.
This isn’t just a preference – it’s biology because the nose is a highly sophisticated filtering, warming, and humidifying system (kinda like your body’s natural air conditioner).
In contrast to this, the mouth is more like an emergency entrance: helpful in a sprint or an emergency but not great for day-to-day operations.
Thanks to modern life and things like stress, poor posture, chronic busyness, and childhood habits (things like allergies, dummy use, or even mimicking others) many people unconsciously switch to mouth breathing and make this their default mode.
This is pretty serious over time because – when we make the shift to living out our lives as mouth breathers – our nervous system, health, and even personality start to shift in subtle but serious ways.
In other words, when we’re not breathing through our noses, we start to go deeper and deeper into being unreal over REAL.
What Happens When You Mouth Breathe
Mouth breathing isn’t just less efficient – it literally alters the entire rhythm of your body:
- It dries out your mouth and throat, leading to dental issues, bad breath, and sore throats.
- It reduces oxygen absorption which makes you feel foggy, sluggish, or anxious all the time.
- It encourages shallow chest breathing, which tells your nervous system, “I’m in danger” (even when you’re just watching telly or something).
- In short, it keeps you stuck in sympathetic dominance – which means that you spend most of your time in the fight-or-flight state and so you find it hard to relax, process emotion, or feel safe.
But, wait, there’s more:
Over time, chronic mouth breathing can change the shape of your face, impact sleep quality (hello, snoring and sleep apnoea), mess with your digestion because the parasympathetic nervous system isn’t kicking in (which is bad because it’s responsible for “rest and digest”), screw up your immune system, diminish your ability to focus, and affect your emotional stability.
It’s really no exaggeration to say that it silently chips away at your vitality and your realness which is why if you’re dealing with any of these symptoms it might be time to start regulating your nervous system by training yourself to breathe properly.
The Nervous System Connection: Why Regulation Is Everything
Your nervous system is the command centre for everything you do and the decisions you make as you go through life: how you think, feel, act, and connect with others.
When it’s regulated, you feel grounded, resilient, open; when it’s dysregulated, you feel scattered, reactive, anxious, numb, or on edge.
Luckily, breathing is one of the few bodily functions that is both automatic and under conscious control which makes it your gateway into regulating the nervous system.
This is really important because:
Consistent and sustained nose breathing signals to your body: “You’re safe“.
Why?
Because nose breathing encourages a slower, more rhythmic breath which activates the parasympathetic nervous system – your “rest and digest” state – and triggers the release of nitric oxide, a powerful molecule that improves blood flow, oxygen efficiency, and immune function.
When the parasympathetic system is active, your body isn’t scanning for danger and doesn’t perceive ‘threats’ everywhere.
This means:
- You’re less likely to interpret situations (or people) as threats when they’re not.
- You’re more likely to process emotions instead of suppressing or projecting them (because you can tell the difference between emotional discomfort and physical danger).
- Internal ‘threats’ like shame, guilt, and trauma (the Unholy Trinity) are less overwhelming because your body believes it can handle them (again, because you can tell the difference between emotional discomfort – which you can always handle – and actual physical danger).
In short, when your breath tells your body it’s safe, you have the space to actually tap into your REALNESS and act as who you actually are instead of your ego.
The Life-Changing Benefits of Nose Breathing
Let’s unpack this a little more and break down some of the powerful benefits nose breathing delivers, across physical, mental, and emotional levels:
Physical Benefits
- Improved oxygen uptake: Nasal passages slow air down, giving the lungs more time to extract oxygen and to distribute it throughout your body.
- Nitric oxide production: Enhances circulation by opening up your blood vessels, supports immunity, and acts as a natural antiviral and antibacterial.
- Lower heart rate and blood pressure: Promotes cardiovascular health and calm which allows you to better face life in a real way (instead of having things be distorted because you’re perceiving threats and get lost in ego).
- Better sleep: Reduces snoring, improves oxygen delivery, and supports deeper rest and more R.E.M sleep.
- Supports proper oral and facial development: Especially important in children but relevant for adults too.
Mental Benefits
- Sharper focus and cognitive function: Because more oxygen = clearer thinking.
- Greater mindfulness: Breathing through your nose slows things down and makes you more present in your own life (not your ideas about it).
- Better emotional regulation: You become less reactive and more resilient and responsive to what’s actually happening.
- More flow: You stop putting obstacles in your own way and increase your ability to build flow with life instead of forcing yourself against it.
Emotional Benefits
- Reduced anxiety and panic: Because your body is no longer stuck in fight-or-flight and so you can feel safe instead of seeing ‘threats’ everywhere.
- Increased sense of safety: Internally and externally – making it easier to connect and relate authentically and with realness.
- Deeper emotional processing: A regulated system can actually feel, rather than freeze or freak out and so you can allow your emotions to do what they need to do without identifying with them or getting lost to them (emotions are e-motion, energy in motion).
My book Trust: A Manual in Becoming the Void, Building Flow, and Finding Peace will take you deeper into nervous system regulation and will guide you into levelling yourself up in a real way.
Living in Survival Mode vs Living in Realness
When your nervous system is dysregulated, you can’t trust yourself or life:
This is because, when you’re in sympathetic dominance and seeing ‘threats’ all over the place, everything feels too fast, too much, or too uncertain.
In this state, you become reactive instead of responsive and defensive instead of open; you constantly micromanage, overthink, numb out, or lose touch with yourself.
The ‘good’ news is that when your system is regulated, you can trust life again:
You can meet reality with presence; you can discern what’s real and what’s just old shame, guilt, and/or trauma talking; you can show up from a place of flow, rather than force.
This is the heart of living your real life – a life where your actions match your values, your emotions have space to move, and your energy isn’t hijacked by unconscious stress.
What’s remarkable is that simple nose breathing is one of the simplest, most powerful ways to get there.
Practical Ways to Reclaim Your Breath and Regulate Your System
So how do we actually make nose breathing the default again?
Here’s a simple plan of action to get you started:
1. Start Noticing
Awareness is always the first step:
Start by committing to catching yourself throughout the day by constantly asking yourself if you’re breathing through your nose or mouth?
If it’s the latter, gently switch (stop and pay attention to how you’re breathing right now as you read this article).
Pro tip: Use a recurring habit as a trigger – like being in the car (this is the one I use):
Every time you get in, commit to nasal breathing for the journey – it turns a mundane moment into a kind of ritual or practice (and may even reduce road rage as well).
2. Tape Your Mouth at Night
This may sound a tad extreme but mouth taping at night (using a small piece of gentle medical tape) is safe for most people and can train your body to nose breathe while you sleep.
Start slow and research it properly first but this has been life-changing for many (I used this method when I first started training myself to nose breathe.
3. Diaphragmatic Breathing
Place one hand on your heart and one on your belly:
When you breathe, only the belly hand should move. That’s diaphragmatic breathing and it’s deep, grounding, and restorative.
The more you do this, the more you’ll naturally breathe from your diaphragm during the day and your breath becomes slower, deeper, and more nourishing.
When you combine this with nose breathing you can take yourself into deep regulation.
4. Try the 4-7-8 Technique
This classic breath practice activates the parasympathetic system:
- Inhale through your nose for 4 seconds.
- Hold your breath for 7 seconds.
- Exhale through your nose for 8 seconds.
Do this for as long as you like, 1–2 times throughout the day. It’s especially powerful before bed, after conflict, or during stressful events. You can also do it when you’re meditating.
5. Move and Breathe
Pair nose breathing with light movement like walking or (yin) yoga.
This builds lung capacity and allows you to nose breathe even when you’re exerting yourself.
Over time, try doing light exercise while only breathing through your nose – it might feel hard at first but strengthens your breath control and nervous system resilience.
6. Use Nose Breathing as a Meditation
Forget sitting still and doing classical ‘meditation’ if that’s not your thing:
Set a timer and spend 5–10 minutes each day focusing on your nose breathing.
Feel the air come in and out and every time your mind wanders, come back to the breath. It’s simple, effective, and rewires your system toward calm.
Final Thoughts on Nose Breathing: Trust Life, One Breath at a Time
In a world that constantly asks us to identify with performance, pressure, and panic, it’s easy to forget something as basic and brilliant as nose breathing.
It’s something that can help us return to what’s real, get out of our heads and back into our bodies, and trust that safety isn’t something we chase but something we signal, breath by breath.
The bottom line is that if you want to trust yourself and life, you need a regulated nervous system, and – if you want a regulated nervous system – start with your nose.
This isn’t just biohacking but ancient wisdom, biology, and a return to simplicity.
