Have you ever felt your chest tighten and your breath quicken the moment you have to speak in front of an audience? You’re not alone. Most of us don’t realize how much our breathing impacts the way we feel, especially when it comes to public speaking. Shallow, rushed breaths only make the nerves worse, creating that shaky voice and racing heart we all dread. But here’s the good news: mastering your breathing can be a complete game changer for public speaking anxiety.
In this post, I’m sharing the incredible benefits of correct breathing, practical techniques you can use, and how to turn correct breathing into a skill that becomes your biggest asset.

How Stress Affects Your Breath and Confidence
Breathing and anxiety are deeply connected. When we’re stressed – whether from a looming deadline, an intense conversation, or a high-stakes presentation – our body slips into “fight or flight” mode: heart rate spikes, the chest tightens, and breathing becomes shallow and rapid. What’s alarming is that many of us operate like this almost constantly.
Thanks to endless to-do lists and long hours hunched over devices, shallow breathing has now become the norm for many of us. There’s even a term for it – “email apnea” – when we unconsciously hold our breath while checking messages or working on a screen. I’ll admit, I catch myself doing it more often than I’d like. Have you?
This constant state of stress-breathing doesn’t just affect your health – it also has a big affect on public speaking. Shallow chest breathing limits oxygen, ramps up anxiety, and undermines vocal control. You might feel your voice quiver, your heart race, or find yourself rushing through sentences without pause.
But here’s the good news: breathing is a skill you can retrain. With the right techniques, you can calm your nerves, ground your energy, and speak with clarity and confidence.
That’s why breathing was featured in my Top 10 Techniques to Manage Public Speaking Anxiety – and in this post, I’ll share three powerful methods that can help you break the cycle and perform at your best.

Best Breathing Techniques for Public Speaking Anxiety
Now that you understand the importance of correct breathing, let’s dive into three of the most effective and practical breathing techniques that you can start using today.
1. Diaphragmatic Breathing for Calm and Control
Diaphragmatic breathing or “belly breathing” is one of the most effective ways to calm your nervous system. It involves breathing deeply into your diaphragm rather than your chest, allowing you to take in more oxygen, reduce anxiety, and project your voice more effectively.
How to practice
- Sit or stand comfortably with your shoulders relaxed.
- Place one hand on your chest and the other on your belly.
- Inhale deeply through your nose, allowing your belly to rise while keeping your chest still.
- Exhale slowly through your mouth, feeling your belly fall.
- Repeat for several breaths, focusing on keeping your breathing deep and steady.
2. Box Breathing to Manage Stress and Focus
Box breathing is a simple yet powerful technique to manage stress and improve focus. It involves taking deep breaths in a controlled, rhythmic pattern, which helps regulate your heart rate and calm your nervous system.
How to practice
- Inhale through your nose for a count of four.
- Hold your breath for four counts.
- Exhale through your mouth for four counts.
- Hold your breath again for four counts.
- Repeat the cycle for several minutes.

3. Pacing Your Breath for a More Impactful Delivery
We spoke about how when we’re nervous, we tend to speak quickly, which adds to the stress. Pacing your breath with your words is an excellent way to stay in control while speaking. This technique helps you slow down, stay calm, and speak with more impact.
How to practice
- As you practice your speech, mark places where you can pause and take a breath.
- This can be after a key point, between slides, or at the end of a paragraph.
- Use these pauses to take a deep breath and reset before continuing.
This simple practice not only calms your nerves but also makes your speech more impactful. Pausing gives your audience time to absorb what you’re saying, and it gives you time to gather your thoughts.
Breathing as a Long-Term Tool for Confidence and Calm
Learning to control your breath is a skill and like any skill, it takes time and practice to master. But once you do, you’ll have more control over your emotions, your energy, and the way you present yourself.
These breathing exercises aren’t just for public speaking, they are invaluable tools that are available to you in your daily life.
Whether you’re preparing for a big presentation or simply want to feel more grounded in your daily life, correct breathing is a powerful tool that’s always available to you.
So next time you step up to speak – or find yourself in any stressful situation – take a deep breath, relax, and let your words flow. You’ve got this!
