Three Breathing Techniques for Stress (And How to Use Each)

Of all the wellness tools you can pick up, breathwork is the one you literally already own. You can do it at your desk, in the car park before a meeting, in bed at 3am, or mid-workout when your form starts wobbling. You don’t need an app. You don’t need a teacher. You don’t need to spend anything.

And unlike most wellbeing advice — which tends to ask you for six weeks of practice before paying out — the right breathing technique works in minutes. Not because it’s magic, but because it’s the only conscious lever you have on your own nervous system.

Why your breath is such a powerful lever

Your nervous system has two main settings. The sympathetic branch — fight, flight, do the thing now — revs you up. The parasympathetic branch — rest, digest, recover — calms you down. Most of modern life keeps the first one mildly switched on all day, which is why “a bit stressed but functional” has become so many people’s baseline.

Breathing is the only process your body does both automatically and consciously. Your heart rate, your digestion, your blood pressure — you can’t change them on purpose. But you can absolutely change your breath. And because the breath is wired into the same nervous system that governs all the rest of it, changing the breath changes everything else downstream.

Slow, deep breaths nudge you towards parasympathetic — calmer, steadier, more present. Quick, sharp breaths nudge you the other way. Knowing which to use, and when, is the whole skill.

Technique 1: Box Breathing (for calm and focus)

Box breathing is used by everyone from Navy SEALs to overworked parents because it’s genuinely simple and it works reliably. It’s the all-purpose tool of the breathwork world.

How to do it

• Breathe in through your nose for a count of 4
• Hold the breath for a count of 4
• Breathe out through your nose (or pursed lips) for a count of 4
• Hold empty for a count of 4
• Repeat for a minute or two. Five rounds is plenty if you’re short on time.

The four phases form a “box” — equal sides — which is where the name comes from. You can scale the count up or down depending on lung capacity. Some people find 5 or 6 feels more natural. The exact number matters less than keeping the four phases even.

When to use it

• Before a difficult conversation or meeting
• Before walking on stage or into an interview
• The first ten minutes after sitting down at your desk in the morning
• Right before sleep, lying in bed
• Whenever you notice your jaw is clenched or your shoulders are at your ears

The first time you do it, you’ll feel your heart rate visibly settle. By the third or fourth round, your head usually feels clearer. By round five, you wonder why you don’t do this all the time.

Technique 2: Extended Exhale (for stress in the moment)

When you’re actually stressed — not low-grade buzzing, but genuinely heart-thumping, palms-sweating stressed — box breathing can feel like too much patience to summon. The extended exhale is the panic-button version.

The principle: when you breathe out for longer than you breathe in, you stimulate the vagus nerve. That’s the long nerve that runs from your brainstem down into your gut, and it’s the main physical channel between your conscious choices and your unconscious calm. A long exhale tells the vagus nerve, in effect, “we’re safe. Stand down.”

How to do it

• Breathe in through your nose for 4 seconds
• Breathe out, slowly, through your nose or pursed lips for 6–8 seconds
• Don’t hold — just keep cycling
• Continue for 1–2 minutes

The classic “4-7-8 breathing” you may have heard about is a version of this, with a hold thrown in. The hold is optional. The long exhale is the part that actually does the work.

When to use it

• When you can feel adrenaline before you can name the trigger
• After a near-miss in traffic
• When you’ve just opened an email you didn’t want to see
• 3am wakeups where your mind has switched on uninvited
• Before any test, performance or moment that’s making your hands shake

Two minutes is usually enough to bring you down meaningfully. Five is enough to feel functionally yourself again.

Technique 3: Nasal-Only Breathing (the daily upgrade)

The first two techniques are tools for specific moments. This one is a lifestyle adjustment that quietly improves everything — sleep, exercise tolerance, focus, even immune function.

The simple ask: breathe through your nose more often. Including during easier exercise. Including, ideally, while you sleep.

Why this matters more than it sounds:

• Nasal breathing filters and warms the air before it hits your lungs. Mouth breathing skips that step entirely, which is one reason chronic mouth breathers tend to catch more colds.
• Your nose produces nitric oxide as you breathe through it — a gas that helps open your airways and improves how your body uses oxygen. Mouth breathing skips this too.
• Nasal breathing naturally slows your pace because the airway is smaller. This regulates your breathing rate without you thinking about it.
• It builds CO2 tolerance over time, which sounds technical but translates to feeling less out of breath during exercise.

How to practice it

Start small. While walking, try keeping your mouth closed and breathing only through your nose. If you have to slow down to maintain it, slow down — that’s the practice. Do the same on the bike or cross trainer on easy days.

For sleep, some people use mouth tape (gentle medical tape across the lips) as a training tool to encourage nasal breathing overnight. Sounds dramatic. Works remarkably well for people who wake up with a dry mouth or sore throat.

Common breathwork mistakes

A few things people get wrong when they start:

• Over-breathing. Forcing big dramatic inhales doesn’t calm you down — it usually does the opposite. The breath should feel relaxed, not effortful.
• Counting too aggressively. If a 4-second inhale is uncomfortable, drop to 3. The point isn’t the count; it’s the rhythm.
• Tensing the shoulders. Watch yourself in a mirror once. If your shoulders rise on every inhale, the breath is staying in your chest. Better breathing happens in the belly — your stomach should move out gently on the inhale.
• Doing it once and expecting magic. Each session works in the moment, but the bigger benefits (lower baseline stress, better sleep) come from repetition. A few minutes a day for a few weeks beats one heroic 30-minute session.
• Treating it like medicine. Breathwork helps with normal stress. It is not a replacement for professional help if you’re in genuine crisis or dealing with serious anxiety. Use it alongside, not instead of.

When to use which: a quick reference

• Background stress, focus, sleep: Box breathing
• Acute stress, panic, adrenaline: Extended exhale
• Daily life, exercise, energy: Nasal-only

If you only learn one: extended exhale. It’s the most reliably powerful in the moments you most need it.

Using breath inside your training

The same principles apply at the gym — arguably more so, because exercise is when most people’s breathing falls apart.

• Lifting: Breathe in on the lowering phase, breathe out on the effort phase. Never hold your breath on a heavy rep unless you’ve been specifically coached to (it raises blood pressure quickly).
• Cardio: Try nasal-only breathing on easy cardio days — treadmill walks, bike, cross trainer at moderate pace. It’ll feel harder at first, then your tolerance builds and your effort feels lighter.
• Stretching: Long, slow exhales deepen the stretch because the muscle releases more on the out-breath than the in-breath. The Stretch Mobility & Core, Yoga and Pilates classes at Atlantis all build this skill naturally.
• Cool-down: Finish a session with two or three minutes of box breathing, ideally in the sauna or by the pool. The nervous system shift you build in those few minutes is what carries the calm into the rest of your day.

Breath for sleep specifically

If you’re reading this at 1am with your phone too close to your face, this section is for you.

The two breathwork tools for sleep:

• Before bed: Five minutes of box breathing while lying down, eyes closed. Often this alone is enough to take you under.
• If you wake in the night: Extended exhale — 4 in, 8 out, through the nose, quietly. The long exhale will gently bring you back towards sleep without the wakefulness spiral.

The aim isn’t to “force” sleep (forcing sleep is a great way to stay awake). It’s to take the pressure off the wakefulness — let your nervous system settle — and then let sleep arrive on its own.

And when you want to go deeper than self-practice

Sometimes you want guidance rather than going it alone. The slightly awkward truth about self-led breathwork is that you can’t fully relax while simultaneously being the person guiding the relaxation. Part of your attention has to stay “in charge.”

Reiki therapy with Sean at Atlantis is a calm, private hour where breath, stillness and deep relaxation come together in a way that’s hard to replicate on your own. Sean has thirty-plus years of practice, including time studying in China under Master Yu Tian Jian. People often describe their first session as the first time in years they’ve actually switched off — not just relaxed, but properly off.

And if you’d rather build breath awareness in a more familiar movement-based setting, the gentler classes on our timetable — particularly Yoga, Fitness Yoga and Stretch Mobility & Core — teach the same principles through movement.

A final small ask

If you read this far and didn’t practise even one technique, do this now: breathe in for 4, out for 6 or 7. Just once. Repeat three more times.

Notice anything different? Most people do. That’s the whole proof. Tools that work in 30 seconds are worth keeping in your pocket for the rest of your life.
