The science of stage fright (and how to overcome it) - Mikael Cho

Palms sweaty, heart racing, stomach in knots. You can't cry for help. Not only is your throat too tight to breathe, but it'd be so embarrassing. No, you aren't being stalked by a monster, you're speaking in public, a fate some deem worse than death. See, when you're dead, you feel nothing; at a podium, you feel stage fright.

But at some point we've all had to communicate in front of people, so you have to try and overcome it. To start, understand what stage fright is. Humans, social animals that we are, are wired to worry about reputation. Public speaking can threaten it. Before a speech, you fret, "What if people think I'm awful and I'm an idiot?"

That fear of being seen as an awful idiot is a threat reaction from a primitive part of your brain that's very hard to control. It's the fight or flight response, a self-protective process seen in a range of animals, most of which don't give speeches. But we have a wise partner in the study of freaking out.

Charles Darwin tested fight or flight at the London Zoo snake exhibit. He wrote in his diary, "My will and reason were powerless against the imagination of a danger which had never been experienced." He concluded that his response was an ancient reaction unaffected by the nuances of modern civilization. So, to your conscious modern mind,

it's a speech. To the rest of your brain, built up to code with the law of the jungle, when you perceive the possible consequences of blowing a speech, it's time to run for your life or fight to the death.

Your hypothalamus, common to all vertebrates, triggers your pituitary gland to secrete the hormone ACTH, making your adrenal gland shoot adrenaline into your blood. Your neck and back tense up, you slouch. Your legs and hand shake as your muscles prepare for attack. You sweat. Your blood pressure jumps. Your digestion shuts down to maximize the delivery of nutrients
