How to Calm Anxiety: 10 Ways to Calm Your Nervous System With Breathwork

Anxiety can feel like your mind is racing, your body is tense and your thoughts are impossible to switch off. Sometimes there is an obvious reason for it. Other times, you can feel anxious even when, logically, you know that everything is okay.

You might notice a tight chest, shallow breathing, a racing heart, restless thoughts, difficulty sleeping or a constant sense that something isn't quite right.

If you've ever wondered, “Why can't I just calm down?”, you're certainly not alone.

The good news is that calming anxiety isn't always about trying to think your way out of it. Because anxiety affects both the mind and the body, it can be helpful to work with the body too. One simple way of doing this is through the breath.

Breathwork involves deliberately changing or becoming more aware of your breathing pattern. Different techniques can be used for different purposes, including relaxation, grounding and developing greater awareness of the connection between your breathing, thoughts and emotions.

Research into breathing practices is encouraging. A systematic review of 58 clinical studies found that many regulated breathing interventions were associated with reductions in stress and anxiety, although the researchers also emphasized that the type of breathing technique and how it is practiced matter.

So, how can breathwork actually help when anxiety takes hold?

What happens to your body when you feel anxious?

Anxiety isn't simply something that happens in your head.

When you perceive a threat, uncertainty or danger, your body's stress response can become activated. Your breathing may become faster or shallower, your muscles can tense, your heart rate may increase and your attention can become focused on whatever feels threatening.

This response is useful when you genuinely need to respond to danger. The difficulty comes when the body's alarm system stays switched on long after the immediate threat has passed.

You might then find yourself caught in a cycle:

An anxious thought → physical sensations → noticing those sensations → becoming more worried → more physical arousal → more anxious thoughts.

This is one reason learning to work with your breathing can be so useful.

Your breath is something you can consciously influence. By slowing and softening your breathing, you can give yourself a practical way to pause, become aware of what's happening in your body and create a little more space around the anxiety.

The NHS also recommends calming breathing exercises as something people can try to help with anxiety, fear and panic.

Can breathwork really help calm anxiety?

Yes, for many people, breathwork can be a useful tool for reducing stress and anxiety — but it isn't a magic cure, and not every breathing technique will suit everyone.

Research is increasingly exploring the relationship between breathing and anxiety. A 2025 systematic review of 19 studies found that 12 reported significant improvements in anxiety and 9 reported improvements in stress following breathing-exercise interventions. The researchers also noted that larger, high-quality trials are still needed.

Another systematic review found that effective stress-reduction breathing practices tended to involve practices lasting at least five minutes, guidance from a person or structured instruction, and repeated or longer-term practice. Interestingly, the review found that fast-only breathing was not a feature of the more consistently effective approaches.

This is important because breathwork isn't simply about “taking a big breath”.

It's about learning how to relate to your breathing differently.

For someone experiencing anxiety, that might mean slowing the breath, reducing unnecessary effort, extending the exhale, developing awareness of bodily sensations or simply learning to notice the breath without trying to control everything.

What is a simple breathing exercise you can use when you're anxious?

One of the simplest approaches is gentle, slow breathing.

You don't need to force a huge breath into your lungs. In fact, forcing your breathing can sometimes make you feel more uncomfortable.

Instead, find a comfortable position and allow your breath to become gentle and easy.

Try this:

1. Sit somewhere comfortable and let your shoulders soften.

2. Breathe in gently through your nose.

3. Allow the breath to move down towards your abdomen without forcing it.

4. Exhale slowly and comfortably.

5. If it feels natural, make your exhale slightly longer than your inhale.

6. Continue gently for around five minutes.

The NHS recommends a similar calming breathing approach for stress, anxiety and panic, including gentle breathing and allowing the breath to flow comfortably rather than forcing it.

The goal isn't to achieve the “perfect” breath.

The goal is to give yourself an opportunity to slow down.

If focusing on your breathing makes you feel more anxious, stop and return to your normal breathing. You can instead focus on your feet against the floor, the sensations around you or another grounding activity.

How can breathwork become more than something you do when you're anxious?

One of the biggest benefits of breathwork can come from making it part of your regular self-care rather than only reaching for it when you're already overwhelmed.

Think of it like building a relationship with your nervous system.

When you practice regularly, you begin to recognize your own patterns. You may notice when you're holding your breath, when your breathing becomes shallow, when your shoulders tighten or when your mind starts racing.

That awareness can be valuable in itself.

Rather than only noticing that you're anxious when you've reached your limit, you may begin to recognize the earlier signals that your body is becoming stressed.

This is where guided breathwork can offer something different from simply watching a breathing exercise online.

A guided session can give you time and space to slow down, become more aware of your body and explore your breathing with support. Depending on the approach used, breathwork may form part of a wider process of relaxation, self-awareness, emotional exploration and personal development.

What if my anxiety feels bigger than breathing exercises can help with?

Breathwork can be a valuable complementary practice, but it isn't a replacement for appropriate mental-health care.

If anxiety is persistent, overwhelming, affecting your everyday life, causing panic attacks or making it difficult to function, it's important to seek appropriate professional support. Talking therapies and other evidence-based treatments can be very helpful for anxiety, and the NHS recommends seeking professional help when anxiety is difficult to manage.

Breathwork can sit alongside that support rather than having to compete with it.

For some people, it becomes a practical way of reconnecting with the body, creating moments of calm and developing greater awareness of their internal experience.

And sometimes that's where meaningful change begins — not by forcing yourself to stop feeling anxious, but by learning to meet what you're experiencing with a little more awareness and compassion.

A final thought

If you're constantly asking yourself, “How do I calm my anxiety?”, you may be looking for a way to feel more in control of your experience.

Your breath can be one place to start.

You don't have to change everything at once. You don't need to master complicated techniques. Sometimes, simply stopping for a few minutes, feeling your feet on the ground and allowing your breathing to become slower and softer can create enough space to take the next step.

Breathwork isn't about escaping your emotions.

It's about learning to be present with yourself.

And with regular practice, that can become a powerful part of learning how to respond to stress differently.
