Have you ever experienced a sudden rush of panic when a deadline approaches? Or did you feel your heart pound when receiving an unexpected email?
That intense reaction is your fight-or-flight response, a term first introduced by Harvard psychologist Walter Bradford Cannon in his book The Wisdom of the Body (1932). This term refers to a primal survival system designed to protect you from danger.
Understanding the fight-or-flight response is crucial, especially for Australian professionals navigating the pressures of urban life and a competitive workplace. This knowledge is fundamental to effective improvement of mental health at work and learning how to stop worrying constantly.
This article explains the science behind the response, details its symptoms, provides real-world examples, and shows you how to regain control of your body’s stress system.
What is Fight-or-Flight and the Science Behind It?
The fight-or-flight response is an involuntary, biological survival mechanism. It is your body’s automatic reaction to perceived threats that enables you to either stand and fight or turn and run from a potential problem.
The hypothalamus, the control center in your brain, stimulates this response. When a threat is detected, whether physical or psychological, the hypothalamus signals the adrenal glands to flood the body with potent stress hormones, primarily adrenaline and cortisol.
This sudden chemical cascade dramatically alters your physiology:
- Heart Rate: Increases rapidly to pump blood to major muscles.
- Breathing: Becomes fast and shallow to increase oxygen intake.
- Muscles: Tense up, ready for immediate action.
- Digestion/Immune System: Processes are temporarily shut down or slowed, diverting energy toward survival.
In prehistoric times, this system was essential for escaping a dangerous animal. Today, what is fight-or-flight a response to in modern Australia? Psychological threats like mortgage stress, job insecurity, or high-stakes confrontations typically trigger it.
What Are Fight-or-Flight Response Examples and Their Symptoms?
The fight-or-flight response can occur in our daily lives, not to mention in the high-pressure working life in Australia. Examples of the fight-or-flight response in a professional context often look very different from the physical threats the system was designed to respond to.
For example, your manager schedules an urgent, unexpected meeting with you at 4:30 PM. Even if you know you haven’t done anything wrong, the uncertainty and fear of performance scrutiny trigger the same hormonal response: your palms sweat, and you can’t focus on any work leading up to the meeting. The pressure to “get it right” in a high-pressure Australian corporate environment often activates this stress response repeatedly.
We can divide the fight-or-flight responses into two categories: physical and emotional symptoms.
Physical Symptoms
- Rapid heart rate and increased blood pressure
- Quick, shallow breathing
- Muscle tension and trembling
- Pale or flushed skin
- Dilated pupils: Pupils widen to let in more light, sharpening vision and increasing awareness of surroundings.
- Digestive or appetite changes
- Sweating
Emotional Symptoms
- Heightened alertness/hypervigilance
- Laser focus (tunnel vision)
- Worrying, Anxiety, anger, or agitation
What Are the Impacts of Excessive Fight-or-Flight Mode?
Your body is designed for the fight-or-flight response to last only as long as the immediate threat exists (a few minutes, at most). The critical issue today is that psychological stressors, such as deadlines, financial worries, and team conflict, can keep the system switched ON for hours, days, or weeks.
This raises the question: how long can your body remain in fight-or-flight mode? It can remain chronically activated, constantly bathing your system in cortisol. This chronic activation has severe consequences, leading to:
- Burnout: Sustained emotional and physical exhaustion.
- Physical Illness: Weakened immune function, digestive problems, and chronic headaches.Anxiety
- Disorders: The nervous system remains perpetually on alert, contributing to generalized anxiety.
- Impaired Cognition: High cortisol levels interfere with the brain’s ability to process memory and make rational decisions.
How to Get Your Body Out of Fight-or-Flight
The good news is that you can consciously signal to your nervous system that the danger is over. This is how you get your body out of fight-or-flight mode:
1. Engage Deep Breathing
This is the fastest way to manually activate the parasympathetic (rest-and-digest) system. Slow, controlled breathing techniques (like Box Breathing or 4-7-8 breathing) tell your brain to stand down.
2. Move Your Body
Since the response floods your muscles with adrenaline for running or fighting, gentle physical movement helps burn off those excess chemicals. Step away from your desk, stretch, or walk around the office block.
3. Ground Yourself Cognitively
Acknowledge the feeling (“I am having a stress response”), then actively challenge the perceived threat: Is the threat real and immediate? Is the situation truly catastrophic? Often, naming the feeling and questioning the danger reduces the intensity of the response.
4. Use Water and Sensory Input
Take a drink of cold water or place cool water on your face. This minor shock to the system can immediately interrupt the hormonal surge and help regulate your heart rate.
Ready to Manage Your Stress Response?
Understanding the fight-or-flight response provides the necessary insight to stop stress before it overwhelms you. While self-management techniques are powerful, sometimes the causes of chronic stress are too deeply rooted, or the anxiety is too persistent, to be resolved alone.
If you are struggling with chronic stress, persistent anxiety, or the long-term effects of a nervous system that won’t calm down, professional support can help you address the root causes and develop lasting coping strategies.

Frequently Asked Questions (FAQs) About Fight-or-Flight Responses
1. How do you know if you’re stuck in fight-or-flight?
You know you’re stuck when you experience chronic hypervigilance (constantly feeling on edge), persistent muscle tension, difficulty sleeping, constant anxiety, and a feeling that your body or mind can’t relax even when you are safe.
2. Is a fight-or-flight response dangerous?
The response itself is a healthy survival mechanism. It becomes dangerous when it is chronically activated. Staying in fight-or-flight for too long floods the body with cortisol, which can lead to long-term health problems like a weakened immune system, anxiety disorders, burnout, and cardiovascular issues.
3. What causes a fight-or-flight response?
The response is caused by the hypothalamus (the brain’s alarm center) detecting a perceived threat. This triggers the release of adrenaline and cortisol. In modern life, common causes include psychological stressors such as tight deadlines, financial worries, interpersonal conflict, and job insecurity.
4. How to calm down from a fight-or-flight response?
You can manually calm the system by engaging the parasympathetic nervous system. The fastest methods include slow, deep breathing (breathwork), gentle movement (walking or stretching), and using cool water on your face to interrupt the hormonal surge.
