Imagine standing in front of a room full of people. Your stomach clenches, your heart races, your palms sweat. You might think this is unique to you, a sign of your personal weakness. But it’s not. Your brain simply interprets the situation as a threat – much like our ancestors’ brains perceived the growl of a predator in the bushes. It’s not your fault; it’s the work of a complex and ancient system.

When you step onto a stage, your brain, bypassing rational assessment, instantly switches into “fight or flight” mode. This lightning-fast reaction is primarily managed by a small but powerful region deep within your brain – the amygdala. Like a smoke detector, it reacts to any hint of danger, even if that danger is just a potential disapproving glance.

This ancient structure, the amygdala, sends signals to the hypothalamus, which then conducts a full symphony of stress. The result is a release of cortisol and adrenaline. These hormones immediately prepare your body for survival: your pulse quickens, blood rushes to your muscles, and breathing becomes shallow. “Just a little longer,” your brain seems to think, trying to protect you from the perceived threat.

We know perfectly well that we are not in physical danger. The audience isn’t about to attack. But the amygdala “doesn’t know the difference.” For it, social disapproval, a potential mistake, or even just the intense focus of many eyes can be as dangerous as a physical threat. It’s like an alarm system that goes off not for a burglar, but for a cat running past the window.

Here’s the interesting part: nervousness itself is just bodily sensations. But we don’t just feel them. We actively interpret them, working ourselves up: “They’ll notice I’m nervous,” “I’m going to make a fool of myself,” “I’m not good enough.” This internal monologue, like a conductor, leads to an even more powerful release of stress hormones.

Your frontal cortex, which should help you logically assess the situation, starts working against you. Instead of saying, “It’s okay, you’re ready,” it begins generating catastrophic scenarios. This process is called cognitive appraisal – and it’s what turns moderate nervousness into a full-blown panic attack. Why? Because the brain perceives these thoughts not as fantasies, but as reality, making the amygdala scream even louder.

For example, thoughts of failure, of “they won’t understand me,” “I’m worse than others,” actually deplete your cognitive resources. This isn’t their nature, but a protective reaction. And it’s this mental rumination, this internal dialogue, that triggers new waves of cortisol, completing the vicious cycle of fear. You essentially “convince” yourself of danger, intensifying physical symptoms. Hence the feeling of “I did so much for them” → “Why don’t they understand me?” → “Why bother trying at all?”

If we’re talking about getting rid of it “once and for all,” the answer is no, and there’s no need to. We cannot “turn off” the amygdala. Moreover, a little nervousness, or as it’s also called, “constructive excitement,” can even be beneficial. It keeps you alert, helps you concentrate, and adds energy to your presentation. Note that even experienced artists and speakers often talk about a slight anticipation and excitement before stepping onto the stage.

The goal is not to suppress all sensations, but to learn to interpret them differently and manage them. You cannot control your reflexes, but you can work with how you react to them and what you do with them. It’s like learning to ride a bicycle: at first it’s scary, uncomfortable, but over time you don’t get rid of the sensation of speed, you start to enjoy it.
