Breathing Exercises for Anxiety

The best breathing exercises for anxiety slow your breathing down and make each exhale longer than the inhale. The simplest is to breathe in through your nose for a count of 4 and out slowly for a count of 6 to 8, for two to five minutes. Simple options include belly breathing, box breathing, 4-7-8 breathing, the physiological sigh, and paced breathing at about six breaths per minute. Practiced for a few minutes a day, these breathing techniques for anxiety can slow your heart rate and ease anxious feelings. They are a self-care skill rather than a treatment for an anxiety disorder.

Breathing Exercises for Anxiety at a Glance

Slow, controlled breathing is one of the most accessible ways to calm your body. It is free, portable, and needs no equipment. Patterns built around long exhales and slow pacing shift the nervous system toward its "rest and digest" mode.

This page presents 10 well-established breathing techniques, what each does physiologically, and when to use which. They work for anxiety, panic, stress, anger, and sleep difficulty — but each shines in different situations.

The Physiology in Brief

Breathing is unique among autonomic functions because it can be both unconscious and consciously controlled. That makes it a direct lever on the autonomic nervous system. Three mechanisms matter most:

• Vagal influence on the heart: Heart rate rises a little on each inhale and falls on each exhale (respiratory sinus arrhythmia), a rhythm controlled largely by the vagus nerve. Slow breathing with longer exhales tends to emphasise the slowing phase.
• Heart rate variability (HRV): Breathing at the resonance frequency (~0.1 Hz, or 6 breaths/min) maximizes HRV, a marker of autonomic flexibility
• CO₂ regulation: Anxiety triggers shallow rapid breathing, blowing off CO₂ and producing the dizziness, tingling, and chest tightness often mistaken for a medical emergency

Most effective techniques exploit one or more of these mechanisms.

1. Diaphragmatic (Belly) Breathing

Best for: baseline practice, learning the foundation

1. Lie down or sit comfortably. Place one hand on your chest, one on your belly
2. Breathe in slowly through the nose, letting your belly rise; chest stays still
3. Exhale slowly through pursed lips, belly falling
4. Aim for 6–10 breaths per minute
5. Practice 5–10 minutes daily

Many people under stress shift toward fast, shallow chest breathing. Practising slow belly breathing when calm makes it easier to use the other techniques when anxious.

2. Box Breathing (4-4-4-4)

Best for: stress, focus, before high-pressure performance

1. Inhale through nose for 4 seconds
2. Hold breath for 4 seconds
3. Exhale through mouth for 4 seconds
4. Hold empty for 4 seconds
5. Repeat for 4–6 cycles

Box breathing was popularized by former Navy SEAL Mark Divine and is taught in some military, police, and first-responder training. The steady count gives an anxious mind something simple to focus on, and many people find it calms them while keeping them alert. See our full guide to box breathing.

3. 4-7-8 Breathing

Best for: sleep onset, acute anxiety, falling back asleep

1. Exhale completely through the mouth, making a soft whoosh sound
2. Close mouth and inhale quietly through the nose for 4 seconds
3. Hold breath for 7 seconds
4. Exhale completely through mouth for 8 seconds (whoosh)
5. Repeat for 4 cycles

Popularized by Dr. Andrew Weil. The long exhale is thought to do most of the work, slowing the heart rate. Direct research on the exact 4-7-8 count is limited, so treat it as one version of slow, long-exhale breathing. Build up gradually; the breath hold can feel uncomfortable at first. More detail in our 4-7-8 breathing guide.

4. Physiological Sigh

Best for: rapid acute stress relief (works in under 60 seconds)

1. Inhale deeply through the nose
2. At the top, take a second short inhale through the nose to fully fill the lungs
3. Exhale slowly and completely through the mouth
4. Repeat 1–3 times

People sigh this way naturally, for example when crying winds down. The second inhale is thought to re-inflate air sacs in the lungs so the long exhale can release more carbon dioxide. Many people feel calmer after one to three sighs. Its repeated form, cyclic sighing (technique 10), was tested in a 2023 Stanford study described below.

5. Paced (Resonance) Breathing

Best for: daily practice, building autonomic flexibility, biofeedback

1. Find your resonance frequency — for most adults, 5–6.5 breaths per minute
2. Standard pattern: 5-second inhale, 5-second exhale (6 breaths/min)
3. Or 4-second inhale, 6-second exhale for deeper parasympathetic shift
4. Practice 10–20 minutes daily

Resonance breathing is among the most-studied breathwork patterns in clinical research. Used in HRV biofeedback for anxiety, depression, PTSD, and chronic pain. Apps and metronomes can help maintain pace.

6. Alternate Nostril Breathing (Nadi Shodhana)

Best for: mental clarity, balance, transition between tasks

1. Sit comfortably. Use the right thumb to close the right nostril
2. Inhale through the left nostril for 4 seconds
3. Close left nostril with ring finger; release thumb
4. Exhale through right nostril for 4 seconds
5. Inhale through right for 4 seconds
6. Close right; release left
7. Exhale through left for 4 seconds
8. That's one cycle. Repeat 5–10 times.

A traditional yogic technique. Small studies suggest it may reduce stress and anxiety, but the research is limited and of mixed quality.

7. Extended Exhale Breathing

Best for: general anxiety, when other patterns feel too complex

1. Inhale through the nose for 4 seconds
2. Exhale through the nose or mouth for 6–8 seconds
3. The exhale should be 1.5–2x as long as the inhale
4. Continue for 5–10 minutes

The simplest evidence-based technique. The principle behind every effective breathing pattern is "exhale longer than inhale." If you remember nothing else, remember that.

8. Lion's Breath (Simhasana)

Best for: tension release, anger, embarrassment when alone

1. Inhale deeply through the nose
2. Open mouth wide, stick tongue out toward the chin
3. Exhale forcefully through the mouth with a "ha" sound
4. Repeat 3–5 times

It looks silly, which is part of its appeal. It stretches the face and jaw and gives a quick physical outlet for tension, and the absurdity sometimes triggers laughter. It has little formal research behind it.

9. Humming (Bhramari Breathing)

Best for: acute anxiety, racing thoughts, sleep onset

1. Sit comfortably with eyes closed
2. Inhale through the nose for 4 seconds
3. Exhale through the nose while humming, like a bee
4. Make the exhale as long as comfortable (8–10 seconds)
5. Repeat 5–10 times

Humming naturally lengthens the exhale, and the vibration may help calm the body. Lab studies have shown that humming sharply increases nitric oxide levels in the nasal passages; its effects on anxiety have been studied less than slow breathing in general.

10. Cyclic Sighing

Best for: daily practice (5 minutes a day)

1. Inhale through the nose
2. Take a second short inhale at the top
3. Exhale slowly and completely through the mouth — make this longer than the combined inhales
4. Repeat continuously for 5 minutes

A 2023 randomized study from Stanford (Balban and colleagues, published in Cell Reports Medicine) asked healthy adults to spend 5 minutes a day for a month on cyclic sighing, box breathing, cyclic hyperventilation, or mindfulness meditation. All four practices helped, but the breathing exercises raised positive mood more than mindfulness did, and cyclic sighing showed the largest gains and the biggest drop in resting breathing rate. It was a single study in people without anxiety disorders, so the result is promising rather than settled.

A 10-Minute Breathing Routine for Anxiety

If you want one session that combines the most useful techniques, try this. Set a timer, sit or lie down, and breathe through your nose unless a step says otherwise.

Once a day is enough to start. If 10 minutes feels too long, the 2-minute version is two minutes of extended exhale breathing followed by one physiological sigh. If you feel dizzy or tingly at any point, you are probably breathing too deeply or too fast; return to small, quiet breaths.

What the Research Says

Breathing exercises are among the better-studied self-help techniques for stress and anxiety, though the evidence is more modest than enthusiastic headlines suggest.

• Meta-analysis of breathwork trials. Fincham and colleagues (2023, Scientific Reports) pooled randomized controlled trials of breathwork and found small-to-moderate reductions in self-reported stress, and smaller benefits for anxiety and depressive symptoms, compared with control conditions. Many included studies were small or had a high risk of bias.
• Slow breathing physiology. A systematic review by Zaccaro and colleagues (2018) linked slow breathing at around six breaths a minute with increased heart rate variability and greater self-reported relaxation and alertness.
• Brief daily practice. The 2023 Stanford study of cyclic sighing (see technique 10) found that five minutes a day improved mood over a month in healthy adults.
• Panic and hyperventilation. Breathing retraining has long been part of cognitive behavioral treatment for panic disorder. Studies suggest it is less important on its own than exposure-based elements, and some therapists caution against using it to avoid feared sensations.

The overall picture: breathing exercises are a low-cost, low-risk way to take the edge off stress and anxious arousal, and they pair well with other skills like grounding techniques and progressive muscle relaxation. They are not a substitute for treatment when anxiety is persistent or disabling.

Which to Use When

• Acute panic / hyperventilation: Extended exhale or cyclic sighing
• Pre-performance stress: Box breathing
• Falling asleep: 4-7-8 or humming
• Daily nervous-system care: Paced breathing or cyclic sighing
• Quick reset between meetings: 1–3 physiological sighs
• Anger or jaw tension: Lion's breath
• Mental clarity / transitions: Alternate nostril

Common Mistakes

• Breathing too deeply. "Take a deep breath" advice often backfires by inducing more hyperventilation. Slow and small is better than big and fast.
• Forcing it. Strain creates more anxiety. Start with comfortable durations and build.
• Only practicing in crisis. Untrained skills aren't available when you need them. Build a daily habit.
• Expecting immediate relief. Some techniques work in 60 seconds (physiological sigh); others build over weeks of practice. Both matter.
• Holding breath when uncomfortable. If 4-7-8 holds feel bad, drop to 4-4-6 or just use extended exhale.

Safety and When to Get Help

• Stop if you feel faint or dizzy. Lightheadedness usually means you are over-breathing. Go back to normal breathing.
• Skip the breath holds if they raise your anxiety. Some people with panic disorder find holds frightening. Extended exhale breathing works without any hold.
• Check with a doctor first if you have a heart or lung condition such as COPD or asthma, or are pregnant, before practicing breath holds or forceful techniques.
• Rule out medical causes. Chest pain, shortness of breath, or a racing heart can have physical causes. If symptoms are new, severe, or don't settle, get medical help.
• Breathing is a tool, not a full treatment. For ongoing anxiety, therapies such as cognitive behavioral therapy have the strongest evidence. Breathing exercises can support treatment for generalized anxiety disorder or panic attacks, but they don't replace it. Our guide to finding a therapist can help.

Conclusion

Breathing techniques can sound too simple to matter, but research suggests slow, controlled breathing has real, if modest, effects on stress and anxiety, and some physiological effects appear within minutes. The catch is that they work best when practiced. Five minutes daily of any of these techniques builds a skill you can reach for when you need it. The best technique is the one you will actually use — start with the simplest, build the habit, and add complexity only if you want to.
