Calm Authority: Regulate Your Nervous System for Poised Public Speaking
The vast majority of people fear public speaking. But nerves aren’t the problem; it’s your response to them. Learn to regulate your nervous system, and transform anxiety into calm authority.
Jerry Seinfeld famously joked that public speaking is more feared than death. The bold statement was grounded in research that showed that approximately 75% of people fear public speaking. Yet, as you progress in your career, public speaking is likely to become an expectation of your role. And it can come in many forms - from taking to the stage to winning an interview room.
It’s easier to avoid public speaking like the masses. But as one of my favourite takeaways from The Slight Edge by Jess Olson highlights, success comes from being willing to do the things that other people aren’t willing to do. When you master public speaking, you give your personal brand a professional edge.
A Slight Edge mindset helped me go from avoiding public speaking as much as possible to actively seeking it out. This included taking on the role of President of my MBA alumni network to starting a YouTube channel and podcast. While it’s one thing to have a goal of improving your public speaking, it’s another to execute it. In this blog, I’m sharing the advice that helped me master my mind and body to embrace public speaking.
You don’t need more confidence to present well or overcome a fear of public speaking - you need to know how to regulate your nervous system. Speaking with impact isn’t all about the exercises you practise beforehand, but how you overcome your nerves in the moments that matter. Control your nerves, express your value with poise and presence, and you win the room.
A powerful presentation or your personal pitch in an interview isn’t simply about psychology; it’s about physiology. The steadier you can appear under pressure, the more powerful, credible and competent you present yourself as.
1. Remind Your Body You're Safe
While many point to the cultural phenomenon of a fear of public speaking, fewer discuss why. However, Robert Kiyosaki in Rich Dad Poor Dad reminds readers that psychologists believe that the fear of public speaking is caused by the fear of ostracism. A fear of standing out, of criticism, of ridicule and of being an outcast. It’s why our body can have such a dramatic stress response to public speaking.
For our ancestors, standing out or being ostracised from the tribe could get you killed. So your brain is hardwired to struggle to know the difference between you being chased by a sabre-tooth tiger and simply speaking to a few people. It’s trying to keep you safe. So remind yourself that you are safe. That in most situations it’s very unlikely that your presentation on, say, last month’s social media numbers, is a life or death situation.
2. The 30-second Reset
Athletes are often coached by sports psychologists to take the time to reset when under pressure. This is why you see them pause before a penalty shot or before serving. Those few moments of mindfulness and regulating their nervous system can make a big difference to their performance in high-pressure situations.
Rapid, uncontrolled breathing can trigger anxiety, panic and stress responses. Techniques like slow-paced breathing have been linked to improved physical and psychological performance outcomes.
Before you take to the stage, make your way to the head of the boardroom or enter an interview, practise a 30-second reset routine. Consider 4 seconds to inhale and 6 seconds to exhale. A longer exhale is key for a calming response on your nervous system:
Fast breathing leads to rushed speech and a shaky voice.
Slow breath supports grounded, controlled delivery.
3. Speak On the Out Breath
Don’t speak on empty lungs. Speak on the out breath.
Speech is physiologically designed to happen on the exhale. Shallow chest breathing tenses and rushes your voice. It’s why you might sound like you’re running out of air. Learning this tip was a game-changer for my entire presenting experience. Because it set the pace for everything else to naturally fall into place.
4. Slow and Steady
Controlling your breath isn’t just about your oxygen supply; it’s about your pacing system.
Fast speech triggers a sympathetic (stress) response, like an increased heart rate and faster breathing. Slower speech restores breathing rhythm and cognitive clarity.
Slow down your speech by 20-30% compared to what feels natural. Your focus on your breath will help to dictate your tempo.
Fast-talkers are often perceived as nervous, while studies in leadership communication found that slower speech increases perceptions of confidence and competence.
Remember:
Speed signals stress to your body and your audience.
Slowness signals safety and authority.
Calm and confident speakers know their voice adds weight and value, so they don’t need to rush through their words. The most talented speakers know it’s not all about the words, but holding the space in between them.
5. The Purposeful Pause
Pauses are the hidden power move for your public speaking, pitches and psychology. They benefit both your body and the audience. By pausing after key points or even mid-sentence, you give your listeners time to process your words, while also giving yourself a moment to catch your breath.
When you pause when you’re asked a question, you also show you are presenting a considered and not rushed response. It shows your diligence and thoughtfulness.
6. One Point Per Person
It’s easier to feel overwhelmed when addressing a room full of people. But you don’t need to see it this way. Take your presentation one at a time, speaking to one person at a time.
This technique changed the way I presented dramatically. The practice means you hold eye contact for a full phrase or sentence per person. It makes the individuals in your audience or around the boardroom feel seen. Meanwhile, it supports your body in feeling less like you're performing to a room and more like you’re connecting with one person at a time.
7. Dress for the Occasion
Your clothes change how you think, feel and perform. As I shared in my recent blog, Dress for the Life You Want: Creating a Visual Identity for Your Personal Brand that Matches Your Dream Life, neuroscience tells us clothes aren’t simply about impressing others - it influences you.
In a psychology study on ’Enclothed Cognition’, participants were asked to wear identical white coats. These were described as either a doctor’s coat or a painter’s coat. Those who were told it was a doctor’s coat performed significantly better on attention-related tasks than those who were told they were wearing a painter’s coat. The research concluded that the symbolic meaning of clothes activates associated mental processes.
Make conscious clothing choices when you’re presenting. Consider your desired perceptions, personal mental processes and your body. What do you feel most confident in? If your body temperature tends to rise when you’re presenting, what is most comfortable and breathable? Choose your outfit as deliberately as your words — it primes your body for poise and authority.
Master your Body, Master your Message
You don’t need more confidence to speak well — you need control over your body, and confidence flows from there. When you regulate your nervous system, your breath steadies, your pace slows, and your presence strengthens. Adding impact to your message, that’s the connection people respond to.
