What nerves are doing to your body

Describe the stress response and explain why it feels worse from the inside than it looks.

Ten minutes before his talk to a group of clinic managers, Arjun (an invented example) can feel his heart beating in his neck. His mouth is dry even though he drank water five minutes earlier. When he picks up the clicker to test it, he sees his hand shaking slightly and puts it down so no one notices. He is fairly sure everyone in the room can tell how nervous he is.

Most people feel nervous before speaking to a group, including many who speak often. These feelings have a clear cause in the body. Other people can see much less of them than you think. For most people they also follow a pattern, and you can plan around it.

What happens in your body before a talk

Standing in front of a group, especially one that will judge you, can trigger the stress response. This is the same system that evolved to help people deal with physical danger. Your body releases adrenaline and other stress hormones, and these cause quick physical changes:

Your heart beats faster and harder to send more blood to your muscles. Your breathing becomes quicker and shallower. Digestion slows, which gives you a dry mouth and an odd feeling in your stomach. Your muscles tense, ready to act, which can show up as shaky hands or a trembling voice. You may sweat, flush or feel hot.

None of this means something has gone wrong. Your body is doing what it is built to do when something feels important and uncertain. Arjun's racing heart, dry mouth and shaking hand are all part of this response.

The response evolved for situations where people had to run or fight. A presentation calls for neither, so the energy has nowhere to go. It comes out as shaking, rushing or fidgeting. The same response also sharpens your attention: you notice more, react faster and feel more alert. Many experienced speakers say they would worry if they felt no nerves before a talk, because that edge helps them perform.

Managing nerves instead of trying to remove them

The aim of this module is to help you manage your nerves. Most people cannot get rid of them, and if you could, you would also lose the alertness they bring. Managing nerves means keeping them at a level where they help you and don't overwhelm you. Lesson 6.2, "Breathing and a routine before you speak", covers the practical tools for doing this.

It also helps to be clear about what nerves mean. They are not evidence that you are bad at speaking. They show that the talk matters to you, and that is a reasonable thing to feel.

How little the audience can see

After Arjun's talk, one of the clinic managers tells him it was the clearest update she had heard in months. He admits how nervous he was, and she says she had not noticed at all.

The audience usually notices your nerves far less than you feel them. Psychologists Kenneth Savitsky and Thomas Gilovich named this the illusion of transparency: the tendency to believe your inner state is more visible to others than it really is. In their research on public speaking, speakers believed they looked more nervous than observers rated them. In the same research, some speakers were told about the illusion before they spoke. Those speakers felt less anxious, and observers rated their talks better.

Think about what other people can actually see. A racing heart, a dry mouth and a tight stomach are invisible to them. A slight hand tremor is hard to see from more than a couple of metres away. A small catch in your voice sounds like nothing to someone who has never heard you speak before. Most of what feels obvious to you from the inside stays private.

Finding the moment your nerves peak

For many speakers, nerves follow a pattern. They build in the hours and minutes before the talk and peak just before you start and for the first minute or so. They ease once you are into the material and the audience is responding.

Knowing your own pattern helps in two ways. First, it shows you that the worst part is temporary, because getting through the first minute usually makes the rest easier. Second, it shows you where to focus your preparation. Some people find the night before worse than the talk itself. Others feel fine until the moment they stand up. Your routine needs to work hardest at the point where your own nerves are strongest. If yours peak at the start, knowing your first few sentences by heart can carry you through that point. Lesson 2.2, "Open strong in the first 30 seconds", suggests this.

When anxiety needs more than practice

Ordinary nerves before a talk are normal, and you can manage them with the tools in this module. For some people, anxiety about speaking goes further. It may stop them taking a role, cause panic attacks, keep them awake for nights beforehand, or affect daily life well beyond presentations. If any of these sound like you, talk to a doctor. In Singapore, mindline.sg is a place to start for support with stress and anxiety. This course teaches practical skills for everyday nerves. It does not replace professional help when you need it.

For the activity, write down the three physical signs of nerves you notice most and the moment when they peak for you.

Write down the three physical signs of nerves you notice most in yourself, and when they are at their worst.
