Breathwork for Anxiety: How Breathing Can Help You Feel Calmer

Anxiety isn't only something that happens in our thoughts.

It can be physical too.

A racing heart. Tightness in the chest. Butterflies or discomfort in the stomach. Restlessness. Shallow breathing. A feeling that you can't quite take a satisfying breath.

This relationship between anxiety and breathing is one reason researchers have become increasingly interested in whether consciously changing the breath might help.

And the evidence is encouraging.

Research suggests that certain breathing practices can reduce anxiety symptoms and influence physiological processes associated with stress and arousal. But not every breathing technique works in the same way, and breathwork shouldn't be presented as a cure for anxiety.

So what actually happens to our breathing when we're anxious? Why might slowing or changing the breath help? And which breathing practices are worth exploring?

Let's take a closer look.

Can breathwork help with anxiety?

Yes, breathwork may help reduce anxiety for some people.

A 2021 meta-analysis examined 40 randomised controlled trials of breathing-focused interventions and found significantly greater improvements in anxiety symptoms compared with control groups. The effects varied considerably between studies, however, depending on factors including the intervention and comparison group.  PubMed

A separate 2023 meta-analysis of randomised controlled trials found that breathwork was associated with a significant reduction in self-reported anxiety, with a small-to-medium overall effect. The researchers nevertheless urged caution because much of the available research had a moderate risk of bias and breathing interventions varied substantially.  Nature

More recently, a systematic review of 19 studies examining breathing exercises for anxiety and stress in adults found that 12 reported significant improvements in anxiety. Its authors also noted the continued need for larger randomised controlled trials.  PubMed

So the emerging picture isn't that breathing is a miraculous treatment for anxiety.

It's more interesting than that.

The breath appears to be one accessible way of working with some of the physiological and psychological processes involved in anxiety.

Why does anxiety affect your breathing?

Our breathing changes all the time.

Walk quickly up a hill and it changes.

Fall asleep and it changes.

Laugh, cry, concentrate, feel frightened or receive unexpected news and it may change again.

Anxiety is no exception.

When we're anxious or perceive a threat, our bodies can prepare us to respond. Heart rate may increase, muscles may tense and breathing can become faster or shallower.

That's useful when the body genuinely needs to mobilise.

But changes in breathing can also contribute to some of the sensations we associate with anxiety.

If breathing becomes excessively rapid or deep relative to what the body requires, we can overbreathe, sometimes called hyperventilation. This changes the balance of carbon dioxide in the blood and can contribute to sensations such as dizziness, tingling, light-headedness or breathlessness.

Those sensations can themselves feel frightening.

For someone prone to anxiety or panic, that can sometimes create a feedback loop:

I feel anxious → my breathing changes → I notice uncomfortable sensations → those sensations worry me → I feel more anxious.

Breathing isn't the cause of every anxious feeling, of course.

But because breathing is connected with our physiological state, it gives us an interesting point of access.

How does breathing help anxiety?

There probably isn't one single mechanism.

Breathing affects several interconnected systems, including respiratory, cardiovascular and autonomic processes.

One particularly well-studied area is slow breathing.

A large systematic review and meta-analysis involving 223 studies found that voluntary slow breathing increased measures of vagally mediated heart-rate variability both during breathing and following practice. Heart-rate variability, or HRV, describes variation in the timing between heartbeats and is one way researchers investigate autonomic regulation.  PubMed

Another systematic review found that slow breathing was associated with changes in autonomic and central nervous system activity as well as increases in measures such as HRV and respiratory sinus arrhythmia. Psychological findings included reduced arousal and anxiety alongside increased relaxation and comfort.  PubMed

This is sometimes simplified online to:

"Take a deep breath and activate your parasympathetic nervous system."

The real physiology is more complicated.

Breathing interacts with heart rate, blood pressure regulation, respiratory sinus arrhythmia, baroreflexes and brain activity. Researchers are still investigating exactly how these processes combine to influence emotional experience.  PubMed

So at Breathe Into, we'd rather say:

Changing the way you breathe may influence physiological processes associated with arousal and regulation.

That's less dramatic than claiming that one breathing exercise "resets your nervous system".

But it's considerably more accurate.

What does the nervous system have to do with anxiety?

The autonomic nervous system helps regulate many processes that happen without us consciously directing them, including heart rate, digestion and aspects of breathing.

You'll often hear its sympathetic and parasympathetic branches described as:

Sympathetic = fight or flight

Parasympathetic = rest and digest

That's useful shorthand, but the reality is more nuanced.

Neither system is "bad".

We need mobilisation. We need energy. We need our bodies to respond when something requires action.

And the aim of breathwork isn't to spend your life permanently relaxed.

A more helpful way of thinking about regulation is our capacity to respond and adapt.

Can we become activated when something demands it?

And can we settle again afterwards?

Breathwork gives us one way to become more aware of our state and, potentially, gently influence it.

Is a longer exhale good for anxiety?

You may have heard advice to make your exhale longer than your inhale.

There's a physiological reason this idea is interesting.

Heart rate naturally tends to increase slightly as we inhale and decrease as we exhale. This relationship is called respiratory sinus arrhythmia.

Slowing the breath changes these cardiorespiratory interactions, and research has found that slow breathing can increase measures associated with vagal activity and heart-rate variability.  PubMed

That doesn't mean everyone needs to follow a precise breathing ratio.

But a comfortable longer exhale can be a simple place to begin if you're looking for a gentle breathing exercise for anxiety.

Later in this article, we'll try a 4-in, 6-out breath.

Is deep breathing always good for anxiety?

Not necessarily.

This is an important distinction.

When people feel anxious, they're often told:

"Take a big, deep breath."

But bigger isn't always better.

Taking repeated, very large breaths can increase ventilation beyond what the body needs. For someone already overbreathing, that may contribute to light-headedness, tingling or other uncomfortable sensations.

Instead of thinking:

deep breath

try thinking:

slow, soft, comfortable breath.

You don't need to fill your lungs as much as possible.

There is no prize for taking the biggest inhale.

What is the best breathing exercise for anxiety?

There isn't currently enough evidence to declare one breathing technique "the best" for everyone.

In fact, a 2024 systematic review looking at brief interventions for state anxiety found inconsistent results from breathing-only techniques. The researchers concluded that the specific technique and the individual using it matter.  PubMed

Another systematic review examining breathing practices for anxiety and stress found that effective programmes tended to avoid exclusively fast breathing and practices lasting under five minutes, while repeated practice and human-guided training were associated with better outcomes.  PubMed

For everyday anxiety, therefore, we'd start gently.

Slow.

Comfortable.

Without forcing the breath.

And with curiosity about how you respond.

A simple breathing exercise for anxiety: 4 in, 6 out

This is a simple practice you can use when you notice yourself feeling unsettled, tense or anxious.

You don't need any equipment.

And you don't have to wait until you're very anxious to practise it.

1. Find a comfortable position

Sit, stand or lie somewhere you feel supported.

There is no perfect breathwork posture.

Allow your shoulders and jaw to soften if that feels comfortable.

2. Notice your breath first

Before changing anything, take a moment to notice how you're breathing.

Is it quick?

Slow?

Shallow?

Easy?

Restricted?

Don't judge it.

Just listen.

3. Begin to slow the breath

When you're ready:

Breathe in gently through your nose for 4.

Breathe out slowly for 6.

Then repeat.

There's no need to take an enormous inhale. Keep the breath soft and comfortable.

4. Continue for a few minutes

Try this for around five minutes if it feels comfortable.

If counting makes you more anxious, forget the numbers.

Simply allow the exhale to become a little longer and slower.

5. Let go of the technique

Return to your natural breathing.

Then notice.

Not:

"Did I do it properly?"

Instead ask:

"What do I notice now?"

Maybe something shifted.

Maybe it didn't.

Both are useful information.

How quickly can breathing exercises reduce anxiety?

Some people notice a change within a few breaths.

Others don't.

And that doesn't mean they're doing it incorrectly.

Brief breathing exercises have produced mixed results in research, while reviews suggest that repeated practice may matter. One systematic review found that interventions involving multiple sessions and longer-term practice were more consistently associated with reductions in anxiety and stress than very short interventions.  PubMed

This is why we don't particularly like presenting breathwork as an emergency button that you're supposed to press when you're already overwhelmed.

It can be useful then.

But it can also become a practice.

A few minutes before work.

After closing your laptop.

Before an important conversation.

When you get into bed.

While sitting in the car before walking into the house.

The breath doesn't only have to be something you notice when things feel difficult.

Can breathwork help a panic attack?

Breathing can form part of strategies used to manage panic.

The NHS advises people experiencing a panic attack to breathe slowly and deeply, remind themselves that the attack will pass and, where possible, remain where they are. It also recommends learning breathing exercises as part of managing panic disorder.  nhs.uk

However, panic attacks can involve intense sensitivity to physical sensations.

This means that intensive or rapid breathwork is not something we'd suggest experimenting with for the first time in the middle of a panic attack.

Gentle, slow breathing may be more appropriate.

If focusing on your breathing makes you more anxious, another grounding technique may feel more supportive, such as feeling your feet against the floor, noticing objects around you or listening to sounds in your environment.

And recurrent panic attacks deserve appropriate professional support rather than relying solely on breathing techniques.

Can breathwork make anxiety worse?

For some people, yes.

That may sound surprising in an article about breathwork for anxiety, but it's important.

Different breathwork practices create very different experiences.

Rapid, deep or prolonged breathing can produce sensations such as:

• tingling
• light-headedness
• temperature changes
• muscle sensations
• altered bodily awareness
• emotional intensity.

Someone who finds unfamiliar bodily sensations frightening may initially find some of these experiences uncomfortable.

Even slow breathing can feel difficult for someone who becomes very focused on whether they're "doing it right".

That's why our approach isn't:

Force your breathing until you feel calm.

It's:

Notice. Listen. Explore.

You are allowed to stop.

You are allowed to change the practice.

And sometimes breathwork isn't the right tool for that particular moment.

What about Conscious Connected Breathing for anxiety?

This is where the research is becoming particularly interesting.

Conscious Connected Breathing (CCB) involves breathing continuously, without deliberate pauses between the inhale and exhale.

It is different from the gentle slow-breathing exercise described above and can create a much more noticeable physical and emotional experience.

Importantly, we now have some specific research examining CCB and anxiety.

A randomised controlled trial published in the Journal of Affective Disorders in 2026 studied 107 adults who were randomly allocated either to a six-week online Conscious Connected Breathwork programme or a waitlist control group.

Participants in the breathwork group completed six weekly 90-minute group sessions.

Their average anxiety score fell by 10.56 points, compared with a reduction of 1.89 points in the waitlist group. The researchers reported a large within-group effect size.  ScienceDirect

That's genuinely promising.

But there are important limitations.

The comparison was with a waitlist, rather than another active intervention. Participants knew whether they were receiving breathwork. Outcomes were self-reported. And we need replication, longer-term follow-up and comparison with established treatments before drawing strong conclusions.  ScienceDirect

So we shouldn't turn one positive study into:

"Conscious Connected Breathing cures anxiety."

It doesn't establish that.

What it does give us is encouraging preliminary evidence that CCB deserves further investigation.

Is Conscious Connected Breathing the same as calming breathing?

No, and this distinction is particularly important for anxiety.

A slow 4-in, 6-out breathing practice is generally intended to slow respiratory rhythm and may feel settling.

Conscious Connected Breathing uses a continuous connected breath and may be considerably more activating.

A CCB session isn't necessarily designed to make you feel immediately calm.

It can involve noticing physical sensations, emotions and changes in awareness.

At Breathe Into, we don't approach that with the expectation that you must experience a dramatic "release".

There is nothing that has to happen.

Instead, the invitation is to stay curious about what you notice.

Does anxiety live in the body?

You'll hear this phrase frequently in wellness conversations.

There is something useful behind it: anxiety unquestionably has physical components.

People may experience changes in breathing, heart rate, muscle tension, gastrointestinal sensations, sweating, dizziness and other bodily experiences.

There is also growing interest in interoception, our perception of signals originating within the body, and its relationship with anxiety.

But we'd be cautious about turning this into the claim that anxiety is simply "stored in the body" and needs to be physically "released".

That goes beyond what current evidence allows us to say.

You don't have to believe that your body is storing an unresolved emotion in order to find body-based practices useful.

Sometimes noticing what you're experiencing is enough.

Does breathwork release stored trauma or emotions?

This is another area where breathwork language can move ahead of breathwork science.

People certainly report emotional experiences during breathwork.

Some cry.

Some feel angry.

Some feel joyful.

Some remember things.

Some feel deeply relaxed.

Some experience very little emotionally.

Those experiences can be meaningful.

But it's different to claim scientifically that breathwork literally releases trauma or stored emotions from particular parts of the body.

At present, we don't have sufficient evidence to make that claim.

At Breathe Into, we don't need to tell you what an experience means.

We can make room for it.

Is breathwork a treatment for anxiety?

Breathing interventions are being investigated as both standalone and complementary approaches to anxiety.

A review of 40 randomised controlled trials found respiratory interventions produced significantly greater improvements in anxiety than controls. A separate review specifically examining people with clinically diagnosed anxiety disorders identified 16 studies and reported improvements across a range of breathwork interventions.  PubMed

But anxiety exists on a spectrum.

Feeling nervous before a presentation is very different from living with a diagnosed anxiety disorder, recurrent panic attacks, severe health anxiety or anxiety that significantly interferes with everyday life.

Breathwork can be one tool.

It doesn't have to be the only one.

Psychological therapies, medication, lifestyle changes, social support, physical activity and appropriate healthcare may all have roles depending on the person and circumstances.

If anxiety is persistent, severe or affecting your ability to live your life, speak to a GP or appropriately qualified mental-health professional.

When is the best time to practise breathwork for anxiety?

You don't need to wait until you're anxious.

In fact, it can be helpful to become familiar with a breathing practice when you're already relatively settled.

You might try it:

• before starting your working day
• between meetings
• before a presentation or difficult conversation
• after work as a transition into home life
• before bed
• when you first notice tension building
• as part of a regular morning or evening practice.

The purpose isn't to become dependent on a breathing exercise every time you experience an uncomfortable feeling.

It's to develop another option.

Something you can reach for when it feels supportive.

Breathwork isn't about getting rid of every anxious feeling

Anxiety is part of being human.

There will be moments when our bodies become activated because something matters.

An important conversation.

A new experience.

Uncertainty.

Change.

Standing up in front of a room.

Waiting for news.

We don't need to label every feeling of activation as something that needs fixing.

Sometimes the question isn't:

"How do I make this feeling disappear?"

It might be:

"Can I stay with myself while this feeling is here?"

That's a subtly different relationship with breathwork.

And it's central to the way we approach it at Breathe Into.

Breathe → Listen → Explore → Intend

Our approach begins with four stages.

Breathe

We begin with the breath.

Not because the breath needs fixing, but because it's something we can return our attention to.

Listen

What's actually happening?

Is the breath fast?

Is your jaw tight?

Can you feel your feet?

Are your thoughts racing?

We're noticing rather than judging.

Explore

What happens if the exhale becomes a little longer?

What happens if you soften somewhere?

What happens if you simply stay curious?

Intend

Only then do we ask what might feel supportive.

Perhaps you'd like to invite a little more steadiness.

Space.

Clarity.

Courage.

Rest.

Not an instruction to feel differently.

An invitation.

A final thought about breathwork and anxiety

The appeal of breathwork is partly its simplicity.

Your breath is already here.

You don't need specialist equipment.

You don't necessarily need an hour.

And there is now meaningful scientific evidence suggesting that particular breathing interventions may help reduce anxiety.

But perhaps the most useful thing about the breath isn't that it can make every difficult feeling disappear.

Perhaps it's that it gives us somewhere to begin.

A way to pause.

To listen.

To notice what is happening before immediately trying to change it.

And sometimes, gently changing the breath may change something else too.

One breath. Then another.

And see what you notice.

Frequently Asked Questions About Breathwork for Anxiety

Can breathing exercises really help anxiety?

Research suggests they can help some people. Meta-analyses and systematic reviews have found reductions in anxiety associated with respiratory interventions, although results vary between breathing techniques, populations and studies. Breathwork is best viewed as a potentially useful tool rather than a guaranteed treatment.  PubMed

What breathing exercise is best for anxiety?

There is no single technique proven to be best for everyone. Gentle slow breathing is well researched and may be a good starting point. A simple option is inhaling comfortably for four counts and exhaling for six, without forcing or taking unusually large breaths.

How long should I do breathing exercises for anxiety?

Research uses many different protocols, so there is no universally established duration. A systematic review found that effective stress/anxiety interventions tended not to use sessions shorter than five minutes and that repeated practice was associated with better outcomes. Five minutes can therefore be a reasonable starting point if it feels comfortable.  PubMed

Why does slow breathing help anxiety?

Slow breathing can influence interactions between respiration, heart rate and the autonomic nervous system. Research shows increases in measures of vagally mediated heart-rate variability during and after voluntary slow breathing, although the relationship between these physiological changes and anxiety is complex.  PubMed

Should I breathe deeply when I'm anxious?

Not necessarily. Aim for breathing that feels slow, soft and comfortable rather than repeatedly taking the largest breath possible. Excessive ventilation can create physical sensations such as light-headedness or tingling that some people find uncomfortable.

Can breathwork stop a panic attack?

Slow breathing is one strategy recommended by the NHS during panic attacks, but there is no guarantee that a breathing exercise will stop one. If focusing on your breath increases your anxiety, another grounding technique may be more helpful. Recurrent panic attacks should be discussed with an appropriate healthcare professional.  nhs.uk

Can breathwork make anxiety worse?

It can for some people. Intensive breathing can create strong physical sensations, and even gentle breath awareness can feel uncomfortable for people who are highly sensitive to bodily sensations. Stop if a practice makes you feel distressed or unwell.

Is Conscious Connected Breathing good for anxiety?

Early evidence is promising. A 2026 randomised controlled trial involving 107 adults found substantial reductions in self-reported anxiety after six weekly online CCB sessions compared with a waitlist group. However, this is an emerging research area and further controlled research is needed.  ScienceDirect

Is breathwork better than meditation for anxiety?

Current evidence doesn't establish that breathwork is universally better than meditation. Different people respond differently, and some practices combine breath awareness, mindfulness and other techniques. The most useful approach is one that is appropriate for you and that you can practise comfortably and consistently.

Is breathwork a substitute for therapy or medication?

No. Breathwork can be explored as a complementary wellbeing practice, but it shouldn't be used as a reason to stop prescribed medication or replace appropriate psychological or medical treatment.
