There is a natural and predictable reaction that most people have to stressful situations, scientists have dubbed this response as the fight or flight response. Meaning that if you’re presented with a stressful situation, or a dangerous situation, your body’s automatic response is to fight that danger or to take flight, to run away from it. For most people, public speaking is not just a stressful situation; it is the most stressful situation that they can think of. In fact, glossophobia, or speech anxiety, is consistently rated as people’s biggest fear. People even rate their fear of public speaking as being greater than their fear of dying. This “fight or flight” response to public speaking situations goes by a particular name in communication studies: communication apprehension. Since communication apprehension is often the most difficult barrier to becoming a great public speaker, it is important that we understand what it is. So, in this lesson we are going to explore the affect that communication apprehension has on the body, and then suggest ways to better manage communication apprehension.

Anybody that has participated in public speaking is likely aware of when they are experiencing communication apprehension, but it is important to realize that this phenomenon is not just happening in one’s head, it affects the entire body. We can now measure, very accurately, the hormones that are released when you are presented with a potentially dangerous or a stressful situation. There are two primary stress hormones: adrenaline and cortisol. It is worth it to think for a second about this as it relates to what we were just talking about with fight or flight. When you’re really excited, or even a little scared, that excitement is your body getting itself ready for something. Adrenaline increases your blood pressure and your heart rate to make you more alert, and is literally preparing your body for a physical event that you might need to do. When you’re in a fight or flight response, the hormone cortisol is also released into your body. Cortisol affects on the critical thinking parts of your brain in a few specific ways. First, Cortisol lowers electrical activity in your brain. Secondly there’s lower neural regeneration, so less total brain cells are being remade over and over again. And third there’s a decrease in efficiency, which means the learning and the critical thinking parts of your brain are less engaged.
The analytical parts of your brain are inhibited by cortisol and adrenaline because your body, from an evolutionary standpoint, wants you to prepare yourself for some physical action; the fight or flight from your threat. This makes sense because if someone thinks too long about an imminent threat, they stay in harms way for a longer period of time and increase the chances of being the target of bodily injury. In fact, it is pretty likely that anyone living amongst our ancestors, that did not possess this particular evolutionary ability, didn’t live long enough to pass on that particular trait to any offspring. In short, communication apprehension is not only a normal bodily reaction, it is a common trait that is widely found among all people across the globe, and throughout history. You should consider yourself in good company if you experience any level of speech anxiety.
The release of cortisol and adrenaline is beneficial from an evolutionary standpoint, but there’s a tradeoff in stressful situations between getting your body ready for a physical altercation and your ability to critically think. It makes sense that our bodies react to things that present an immediate threat to our person, but what is interesting is that when people are in public speaking situations, they tend to react with the same sort of fight or flight response as if they were in dangerous life or death situations. This is a little bizarre considering that they are not under that same threat as if they were confronted with a vicious animal, but it is the same fight or flight response, and the same hormones. As far as your body/brain are concerned: public speaking is a threatening situation.
There are many great suggestions for coping with communication apprehension, but it is worth taking a moment to recognize that this section is not called “eliminating communication apprehension.” That is because even the best public speakers function while they are experiencing speech anxiety. For beginning speakers, the goal should never be to completely eliminate apprehension, because that is setting oneself up for failure. Instead, the goal of individuals that want to improve their public speaking abilities is to function despite the feeling of communication apprehension. The following five suggestions are a helpful starting point to give you ideas for approaching the problem of speech anxiety.
Communication apprehension is not just your mind playing tricks on you, there are significant physiological factors at work when anyone experiences speech anxiety. Your body is releasing hormones, whether you like it or not, and those hormones have a measurable effect on your mood and cognitive abilities. Fortunately there are methods that deal with, and even overcome those barriers to performing in front of an audience. Physically manipulating your body into power poses, preparing well, and reframing the public speaking event have shown to be effective ways to manage communication apprehension. Consider utilizing these strategies the next time cortisol and adrenaline start coursing through your body.
