Have you ever felt nervous before an exam, a big presentation, or a race? You’re not alone! Nervousness is something everyone experiences, but have you ever wondered why it happens? Let’s explore the science behind it and see how professional athletes manage their nerves.
When you feel nervous, your brain sends a signal from the pituitary gland to your kidneys, where the adrenal glands are located. These glands release a hormone called adrenaline. You might recognize the feeling: your heart beats faster, your pupils get bigger, and your muscles get more blood. This is known as the “fight-or-flight” response, which evolved to help our ancestors survive dangerous situations.
This response isn’t just on or off; it varies depending on how threatening or important a situation seems to you. For instance, an interview might trigger a similar reaction to a life-threatening event, but on a smaller scale.
Ever felt those butterflies in your stomach when you’re nervous? That’s because adrenaline redirects blood and energy to vital areas like your heart and muscles, taking it away from your digestive system. This causes the blood vessels around your stomach to tighten, leading to that fluttery feeling.
Professional athletes often use mental imagery to handle stress and nerves. This technique involves imagining themselves performing a skill or technique before actually doing it. It might sound strange, but it activates the same neurons in the brain and can improve performance.
There are different types of mental imagery. Cognitive-specific imagery helps athletes practice skills in their minds. Motivational-specific imagery involves recalling the feeling of winning to boost motivation. Lastly, motivational general mastery helps athletes feel confident by imagining themselves as focused and strong.
Confidence is a key factor that sets successful athletes apart. Coaches often focus on building confidence to help athletes perform better and manage nerves. So, the next time you feel nervous, try preparing like an athlete by using mental imagery and boosting your confidence.

Imagine you’re an explorer on a quest to discover how adrenaline affects your body. Create a comic strip that illustrates the journey of adrenaline from the brain to the adrenal glands and its effects on the body. Use your creativity to show the “fight-or-flight” response in action!
Conduct a simple experiment to understand the “butterflies in your stomach” phenomenon. Try a short, timed activity like a quiz or a race, and note how your body feels before and after. Discuss with your classmates why these physical changes occur and how they relate to adrenaline.
Practice mental imagery techniques used by athletes. Choose a skill or activity you want to improve, and spend a few minutes each day visualizing yourself performing it successfully. Share your experiences with the class and discuss any improvements you notice.
Create a collage that represents confidence. Use images, words, and symbols that inspire you to feel strong and capable. Display your collage in a place where you can see it daily to remind yourself of the power of confidence in overcoming nervousness.
In groups, role-play different scenarios where you might feel nervous, such as giving a presentation or participating in a sports event. Practice using techniques like deep breathing and positive self-talk to manage nerves. Reflect on how these strategies can help in real-life situations.

[Music] Whether you’re waiting for an exam, about to start an important presentation, or at the start of a race, we’ve all experienced nervousness. But why do we get nervous, and could looking at professional athletes help us understand how to effectively cope with it in stressful situations?
Your brain sends a signal from the pituitary gland all the way to the kidneys, where the adrenal gland resides, and this is where adrenaline is released. You may have felt it before: the rapid heart rate, dilating pupils, and increased circulation in your muscles. It’s all part of the fight-or-flight response, which developed in our evolutionary history to help us survive. However, this response isn’t all or nothing; there are degrees of reaction according to the perceived threat or importance you attach to the outcome. For example, something like an interview, which presents a challenge, stimulates the same biological reaction that a threat to your life does, just to a smaller degree.
Feeling those nervous butterflies in your stomach? This is because adrenaline helps redirect blood and energy to the most important parts of your body during stress, like the heart and muscles, and away from your digestive system, causing the blood vessels to close around your stomach and leading to that tingling sensation.
So how do professional athletes handle stress and nerves? The concept of mental imagery is a widely used method in sports. With cognitive-specific imagery, an athlete imagines themselves practicing a technique or skill before competing or training. While it may sound unusual, this actually stimulates the relevant neurons in the brain and has been shown to enhance the specific skill.
Motivational-specific imagery encourages athletes to recall the feeling of winning an event or beating a competitor as a motivational tool. Finally, motivational general mastery is commonly used by athletes to feel more confident. By simply imagining themselves as focused, tough, and having positive thoughts prior to competition, athletes are able to improve performance and overcome nerves.
Confidence, in particular, is a consistent factor that distinguishes successful athletes from others and is a major focus for professional coaches. So next time you feel those nerves kick in, try preparing like an Olympian would.
