Breathing exercises for anxiety
When you're anxious, breathing tends to get fast and high in the chest. Slow breathing with a long exhale is one of the quickest ways to tell your body it can settle. The timer above is set to the physiological sigh: two short inhales, then a long, slow exhale.
Start 5 minutes of cyclic sighingIf you feel anxious right now
- Breathe out first, slowly, through your mouth, as if blowing through a straw.
- Do one to three physiological sighs: breathe in through your nose, take a second small sip of air on top, then let a long breath out.
- Then breathe gently with the orb, making each exhale longer than the inhale. Keep the breaths soft rather than big.
- Notice one thing that's changed, like your shoulders dropping or your hands warming, before you carry on.
Breathing exercises that can help
Physiological sigh
2 in · 1 top-up · 6 out · 6.7 breaths/min
Calming down fast, in the moment
Evidence: Promising, early
4-6 breathing
4 in · 6 out · 6 breaths/min
An easy everyday calm-down
Evidence: Good, via slow-breathing research
7-11 breathing
7 in · 11 out · 3.3 breaths/min
Slowing right down when anxious
Evidence: Indirect, via long-exhale research
Coherent breathing
5.5 in · 5.5 out · 5.5 breaths/min
A daily practice for heart-rate variability
Evidence: Strongest
In the moment, the physiological sigh and the long-exhale patterns (4-6, 7-11) are the quickest to settle you. As a daily practice, coherent breathing for 10 minutes builds a calm habit. Box breathing works for some people, but holding your breath with empty lungs can feel uncomfortable when you're already anxious, so it's not our first suggestion here.
What happens in your body
The exhale is the calming half. Heart rate naturally rises a little as you breathe in and falls as you breathe out. In an experiment with 30 people, making the out-breath longer than the in-breath made them feel more relaxed than slow breathing alone.
Gentle beats deep. Anxious breathing often blows off too much carbon dioxide, which can cause tingling, light-headedness and a racing heart that feed the fear. A clinical therapy for panic disorder teaches people to breathe slower and shallower, not bigger, and in a small trial it reduced panic symptoms. So if a deep breath makes you dizzy, make it smaller.
What the research says
- A 2023 meta-analysis of randomised trials found that breathwork reduced self-reported stress by a small-to-moderate amount compared with control groups, with similar effects on anxiety.
- A 2017 meta-analysis of heart-rate-variability biofeedback, which trains slow breathing at about six breaths a minute, found a large reduction in self-reported stress and anxiety, though many of the studies were small.
- In a month-long Stanford study, five minutes a day of cyclic sighing improved mood and reduced anxiety. Its effect on positive mood was larger than mindfulness meditation's.

When breathing isn't enough
Breathing exercises can help you feel calmer in the moment. They are not a treatment for an anxiety disorder or panic disorder. If anxiety is getting in the way of daily life, talk to your doctor or a mental-health professional: talking therapies such as CBT have strong evidence. If you're in crisis or think you might harm yourself, contact your local emergency number now.
For some people, paying close attention to the breath makes anxiety worse at first. If that happens, stop, breathe normally and ground yourself another way, for example by naming five things you can see.
Breathing safely
The slow patterns here are gentle, but holds and deep inhales can make you light-headed. Stop and breathe normally if you feel dizzy. Never practise breath holds in or near water, or while driving. If you are pregnant, or have a heart, lung or seizure condition or panic disorder, check with a clinician first. Breathing exercises can complement medical care but don't replace it.
Questions
What is the best breathing exercise for anxiety?
For calming down in the moment, the physiological sigh or any pattern with a longer exhale, like 4 seconds in and 6 out. For a daily practice, slow coherent breathing at about six breaths a minute has the most research behind it.
Can breathing exercises stop a panic attack?
Slow, gentle breathing can make the physical symptoms easier to ride out, but it does not reliably stop a panic attack. Keep breaths small and slow rather than deep. If you have panic attacks, talk to a doctor or therapist about treatment.
Why does breathing out slowly help anxiety?
Your heart slows slightly on every out-breath. Making the exhale longer tips each breath towards slowing, and experiments show long-exhale breathing feels more relaxing than slow breathing alone.
How often should I do breathing exercises for anxiety?
Use one to three sighs whenever you notice stress building, and try five to ten minutes of slow breathing once a day. Regular practice matters more than any single session.
