Your heart is racing, your chest feels tight and your thoughts won’t slow down. Whether it’s before a presentation, in a crowded room or lying awake at 3 am, anxiety often shows up in the body first, and one of the first things it changes is your breathing. It becomes fast, shallow and high in the chest.

The good news is that breathing is one part of the stress response you can consciously control. Slowing it down is a simple, free tool you can use anywhere. It won’t make anxiety vanish instantly, and it isn’t a substitute for treatment when anxiety is severe, but it can help you feel steadier, and research suggests regular practice brings modest benefits. Here are five techniques to try, how to do them properly, and when to seek more help.

At a glance

• Breathing exercises can help: a meta-analysis of randomised trials found breathwork was linked to small-to-medium reductions in stress and anxiety.
• Five minutes a day is enough to start: in a Stanford trial, 5 minutes of daily breathing practice for a month improved mood and reduced anxiety.
• Slow, long out-breaths are the common thread in most calming techniques.
• Practise when calm, so the skill is there when you need it.
• It’s a tool, not a cure: if anxiety is persistent or disrupts daily life, talk to a doctor. In India, Tele-MANAS (14416) offers free support around the clock.

How breathing affects anxiety

When you feel threatened, your body’s stress response speeds up your heart and breathing to prepare you for action. Anxiety can switch on this response even when there’s no real danger, and fast, shallow breathing can then make you feel dizzy, tingly or short of breath, which feeds the worry.

Slow breathing, especially with a long, unhurried out-breath, is thought to calm this response by engaging the body’s “rest and digest” system. It also gives your mind a simple, steady thing to focus on.

What the research says:

• A 2023 meta-analysis in Scientific Reports, covering randomised trials with 785 adults, found that breathwork was linked to lower stress, anxiety and depression than control groups. The effects were small to medium, and many studies had limitations.
• In a Stanford study of 111 healthy adults, 5 minutes a day of controlled breathing for a month improved mood and reduced anxiety a little more than mindfulness meditation. A technique called cyclic sighing worked best.
• In a larger 2023 trial of 400 adults, slow “coherent” breathing helped no more than a placebo breathing exercise. Both groups improved, which suggests that taking regular, calm time to breathe and focus may matter more than the exact counting pattern.

In short, breathing exercises are a safe, useful self-help tool for everyday stress and anxiety. They work best when practised regularly, and they don’t promise instant results.

5 breathing exercises to try

Sit or lie comfortably, loosen tight clothing and, if you like, close your eyes. Breathe gently; the aim is slow and comfortable, never forced. If you feel dizzy or light-headed at any point, stop and breathe normally.

1. Belly (diaphragmatic) breathing

The foundation for every other technique, and the one the NHS recommends for stress.

1. Place one hand on your chest and one on your belly.
2. Breathe in gently through your nose, letting your belly rise while your chest stays fairly still. Counting from 1 to 5 can help.
3. Breathe out gently through your mouth, again counting to 5 if it helps.
4. Repeat for at least 5 minutes.

Best for: everyday practice, and as a warm-up for the others.

2. Cyclic sighing (the double-inhale sigh)

The technique that performed best in the Stanford study.

1. Breathe in through your nose until your lungs feel comfortably full.
2. Take a second, short sip of air through your nose to top them up.
3. Breathe out slowly and fully through your mouth, longer than the in-breath.
4. Repeat for about 5 minutes.

Best for: a quick reset when you feel tense; a couple of rounds can take the edge off.

3. Box breathing (4-4-4-4)

Used by athletes and in high-pressure jobs to stay steady. Imagine tracing the four sides of a square.

1. Breathe in through your nose for a count of 4.
2. Hold gently for 4.
3. Breathe out through your mouth for 4.
4. Hold for 4, then repeat for 3–5 minutes.

If the holds feel uncomfortable, shorten them or leave them out. Best for: focus before a stressful task, such as an exam, interview or presentation.

4. Longer out-breath (4-6 breathing)

A simple way to slow your breathing to around six breaths a minute.

1. Breathe in gently through your nose for a count of 4.
2. Breathe out slowly through your mouth or nose for a count of 6, as if blowing gently through a straw.
3. Continue for 5 minutes. As it gets easier, you can try in for 5 and out for 7.

Best for: winding down in the evening or settling before sleep.

5. Alternate nostril breathing (nadi shodhana)

A traditional yoga pranayama practice that many people find calming and centring.

1. Sit upright. Rest your left hand on your lap.
2. Close your right nostril with your right thumb and breathe in slowly through the left.
3. Close the left nostril with your ring finger, release the thumb and breathe out through the right.
4. Breathe in through the right, close it, and breathe out through the left. That’s one round.
5. Continue for 5–10 rounds, breathing slowly and without straining.

Skip it if your nose is blocked. Best for: a calm start to the day, or as part of a yoga or meditation routine.

Who should take care

• Holding the breath (as in box breathing) isn’t advised in pregnancy, or if you have a heart condition, uncontrolled high blood pressure, or a lung condition such as COPD, unless your doctor says it’s fine. Simply leave the holds out.
• Fast or forceful breathwork, such as rapid hyperventilation practices, can cause dizziness or fainting and isn’t recommended for anxiety without guidance.
• If breathing exercises make you more anxious, which can happen when you focus on your breath, try counting, gentle movement or grounding (naming things you can see and hear) instead.

Making it a habit

Breathing exercises work best as a skill you’ve practised, not just an emergency button. Learning a technique when you’re already panicking is hard; using one you’ve practised daily is much easier.

• Pick one technique and practise it for 5 minutes a day for a few weeks. In the Stanford study, the benefits of cyclic sighing grew with each day of practice.
• Attach it to something you already do, such as after brushing your teeth, before checking your phone in the morning, or during your commute (with eyes open!).
• Use it in the moment: a few rounds before a meeting, after a difficult call, or when you can’t sleep.
• Combine it with other habits that ease anxiety: regular exercise, enough sleep, less caffeine and alcohol, and time with people you trust. Physical activity in particular can lift mood; read more on how exercise impacts mental health.

When breathing exercises aren’t enough

Everyday worry and nerves are part of life. But for some people, anxiety becomes constant and hard to control. The NHS describes generalised anxiety disorder as anxiety that affects daily life, often with poor sleep, restlessness, trouble concentrating and physical symptoms such as a racing heart.

Speak to a doctor if:

• anxiety is affecting your work, studies, relationships or sleep
• you’re having panic attacks, or avoiding places and situations because of anxiety
• you’re relying on alcohol or other substances to cope
• you’ve been feeling low or hopeless as well

Anxiety is common and treatable. Talking therapies such as cognitive behavioural therapy (CBT), and sometimes medicines, help most people. Breathing techniques can work well alongside treatment.

• UK: your GP, or self-refer to NHS Talking Therapies; call 111 for urgent advice
• US: call or text 988 for the Suicide & Crisis Lifeline

Get emergency help if you have chest pain, severe breathlessness or fainting. These can feel like panic but need checking, especially if you’ve never had them before. And if you’re thinking about harming yourself, contact emergency services or a crisis line straight away.

Worry can also get in the way of other health goals; read our guide on how worry affects weight loss and what helps.

The bottom line

Your breath is always with you, which makes it one of the simplest tools you have for managing anxiety. Slow belly breathing, cyclic sighing, box breathing, a longer out-breath and alternate nostril breathing can all help you feel calmer. They won’t switch anxiety off instantly, but practised for a few minutes each day, they can make tense moments easier to ride out. If anxiety is persistent or overwhelming, you don’t have to manage it alone: reach out for professional support.

Frequently asked questions

Do breathing exercises really help anxiety?

They can. Research suggests breathwork leads to small-to-medium reductions in stress and anxiety, especially with regular practice. They’re a helpful self-help tool, but not a replacement for treatment if anxiety is severe or persistent.

What is the best breathing exercise for anxiety?

There’s no single best one. Techniques with a slow, long out-breath, such as belly breathing, cyclic sighing and 4-6 breathing, are good places to start. In one Stanford study, cyclic sighing improved mood the most.

How quickly do breathing exercises work?

Some people feel calmer within a few minutes, but effects vary. The biggest benefits come from practising for about 5 minutes a day over several weeks.

What is cyclic sighing?

It’s a breathing technique where you breathe in through your nose, take a second short breath in to fill your lungs, then breathe out slowly through your mouth. Repeat it for about 5 minutes.

What is box breathing?

Box breathing means breathing in for 4 counts, holding for 4, breathing out for 4 and holding for 4, then repeating. Leave out the holds if they feel uncomfortable, or if you’re pregnant or have a heart or lung condition.

Can breathing exercises stop a panic attack?

Slow breathing can help you ride out a panic attack and feel more in control, but it may not stop one completely. If you have frequent panic attacks, speak to a doctor, as effective treatments are available.

When should I see a doctor about anxiety?

See a doctor if anxiety is constant, hard to control, or affects your sleep, work or relationships, or if you have panic attacks. In India, you can call Tele-MANAS on 14416 for free, confidential support at any time.
