Have you ever felt your hands shaking or your heart racing before speaking in front of a crowd? That’s adrenaline at work! Adrenaline, also known as epinephrine, is a hormone that kicks in when we face stressors. These stressors can be anything from a sudden scare to playing sports, performing on stage, or even talking to someone you like.
When your adrenal glands release adrenaline, your body goes into overdrive. Blood circulation, breathing, and metabolism rates increase, preparing your muscles for action. This is why you might feel jittery or hear your heart pounding in your ears when you’re nervous.
Adrenaline can make us do incredible things. It helps convert carbohydrates into glucose, which fuels our body, and even makes our muscles stronger temporarily. This is why some people can perform feats of “hysterical strength,” like lifting heavy objects in emergencies, although this phenomenon isn’t fully understood by science.
The hypothalamus, a part of the brain that maintains body balance, controls the release of adrenaline. It regulates functions like sleep, body temperature, hunger, and stress. When we experience stress, we might feel the urge to run, cry, or yell. Crying can release stress hormones, while yelling can activate the amygdala, the brain’s fear center, releasing feel-good chemicals.
Professionals like police officers and military personnel are trained to manage adrenaline through breathing techniques. Breathing is unique because it can be controlled both automatically and consciously, bridging the gap between the body’s “go” system (sympathetic) and “calm” system (parasympathetic).
Try this simple breathing exercise: inhale for a count of four, hold your breath for four, and exhale for four. Repeat this a few times. This technique activates the Vagus nerve, which helps slow your heartbeat, stimulate digestion, and lower blood pressure. With practice, you can use this method to stay calm and make the most of adrenaline when needed.
Next time you’re feeling nervous, give this breathing technique a try and see how it works for you. It’s a strategy used by many, including members of the U.S. Air Force, to stay calm under pressure.
Imagine you’re a superhero who can control adrenaline. Create a short skit with your classmates where you demonstrate how adrenaline helps you in different scenarios, like saving someone or performing on stage. Focus on how your body reacts and the benefits of adrenaline in each situation.
Create an interactive diagram of the human body highlighting the adrenal glands, hypothalamus, and amygdala. Use labels and arrows to show how adrenaline is released and its effects on different body systems. Present your diagram to the class and explain each part’s role in the adrenaline response.
Practice tactical breathing with your classmates. Pair up and take turns guiding each other through the breathing exercise: inhale for four counts, hold for four, and exhale for four. Discuss how this technique makes you feel and when you might use it in real-life situations.
Research a real-life example of “hysterical strength” where adrenaline played a crucial role. Present your findings to the class, explaining the situation, the role of adrenaline, and any scientific theories behind the phenomenon. Discuss why adrenaline is important in emergency situations.
Write a short story or poem about a character experiencing a surge of adrenaline. Describe their physical sensations, emotions, and how they manage the situation using breathing techniques. Share your work with the class and discuss the impact of adrenaline on emotions and actions.
Sure! Here’s a sanitized version of the transcript:

Right before I do any kind of public speaking, my hands start shaking uncontrollably, and I feel like my heart is racing. Thanks, adrenaline. How do I stop this? Adrenaline is one of the most well-known hormones in the animal kingdom, and it’s our response to a “stressor.” Stressors can be anything: a sudden scare, playing sports, skydiving, performing in a play, or even talking to someone you like.
Once it’s secreted by the adrenal glands, adrenaline kicks your body into high gear, increasing blood circulation, breathing, and metabolism rates, preparing the muscles for action. All this activity can have some unusual side effects on your body, especially if you don’t end up running for your life or fighting for your next meal. Adrenaline is why your hands shake when you’re nervous (your muscles are all a quiver with excess energy), and the blood pumping in your ears? That’s also due to adrenaline.
Adrenaline, also known as epinephrine, can enable us to do remarkable things. For instance, when epinephrine is released into the body, it causes us to convert carbohydrates into glucose, the body’s fuel source, and our skeletal muscles actually become stronger. It’s almost like we’re naturally enhancing our muscles, allowing them to perform at a higher level for a short time. This phenomenon is thought to explain “hysterical strength,” where people can lift heavy objects in emergencies. While not fully recognized by science, we can observe the potential strength in our muscles when subjected to extreme stimuli.
Epinephrine is synthesized and released under the direction of the hypothalamus, a control center in the brain responsible for maintaining balance in the body. It regulates various functions, including circadian rhythms, body temperature, hunger, and the balance between stress and relaxation. When humans experience stressors and are flooded with epinephrine, we instinctively want to run, cry, or yell, all of which are valid responses. Tears contain stress hormones, and crying helps release them from the body. Yelling activates the amygdala, the part of the brain that manages fear responses, ultimately releasing feel-good brain chemicals. Engaging in physical activity can also help work the adrenaline out of our system.
But there is another way! Professionals like police officers and military personnel are trained to manage the effects of adrenaline on the job. They often use a simple technique: breathing. While breathing is usually controlled by the sympathetic nervous system (which governs the fight-or-flight response), it can also be consciously controlled. This creates a bridge between the sympathetic and parasympathetic nervous systems.
Think of your body as an engine: the sympathetic system is the gas—GO GO GO! The parasympathetic system is the brake—Calm. During high-stress situations, the body may shut down digestion, and muscle shaking can interfere with fine motor skills, potentially disrupting a speech or performance. When this happens, you can engage the calming parasympathetic system by focusing on your breath.
Tactical or “combat” breathing (as practiced in the military) involves inhaling for a count of four, holding for four, and exhaling for four. If you do this a few times, the Vagus nerve, which connects your brain to your torso, will activate, slowing your heartbeat, stimulating digestion, and lowering blood pressure. With practice, professionals can use this technique to remain calm and harness the benefits of adrenaline when necessary.
So, next time you’re feeling very nervous, try breathing, and let me know what you think! It might seem unconventional, but it’s a technique used by many, including members of the U.S. Air Force, who we’d like to thank for sponsoring this episode.

Adrenaline – A hormone released into the bloodstream in response to physical or mental stress, increasing heart rate and energy levels. – During a race, the runner’s body released adrenaline, helping her to sprint faster.
Stress – A state of mental or emotional strain resulting from demanding circumstances. – Before the big exam, he felt a lot of stress, which made it hard to concentrate.
Hormone – A chemical substance produced in the body that controls and regulates the activity of certain cells or organs. – The hormone insulin helps regulate blood sugar levels in the body.
Metabolism – The set of life-sustaining chemical reactions in organisms that convert food into energy. – Her fast metabolism allows her to eat a lot without gaining weight.
Hypothalamus – A region of the brain that controls functions such as hunger, thirst, and body temperature. – The hypothalamus plays a crucial role in maintaining the body’s internal balance.
Breathing – The process of taking air into and expelling it from the lungs. – During exercise, your breathing rate increases to supply more oxygen to your muscles.
