Introduction
The brain is inarguably the most complex and fascinating part of the human body. And its largest part, the amygdala, aka the lizard brain, plays a super important role: it works to protect us from dangers. But, left unsupervised, the amygdala can hijack our minds and make us do things we can regret later.
If you’ve ever lost control and done something regrettable in the heat of the moment, you’ll know what we mean.
In this article, we’ll cover:
- How the amygdala works
- The role of the prefrontal cortex
- How to activate other parts of your brain to cope with amygdala hijack
- Prevention techniques
Dissecting the Human Brain
First, it’s important to understand how different parts of the brain work together.
Amygdala or the Lizard Brain
The amygdala consists of two clusters of almond-shaped cells at the base of your brain. This part regulates your behavioral and emotional responses.
It’s called the “lizard brain” because it is the primary functioning brain structure in reptiles.
Its main job is protection. For example, if you see a bee, the amygdala signals the hypothalamus to release stress hormones like adrenaline and cortisol, activating your fight-or-flight response.
However, it cannot distinguish between real and imagined threats. So even if the bee poses no danger, your body may still react as if it does.
Prefrontal Cortex
The prefrontal cortex, located at the front of the brain, controls reasoning, planning, decision-making, and conscious behavior.
This is your rational brain—the part that helps you evaluate emotions and respond thoughtfully instead of reacting impulsively.
What is an Amygdala Hijack?
The term “amygdala hijack” was coined by Daniel Goleman in his work on emotional intelligence.
It refers to an intense emotional reaction that is disproportionate to the situation—essentially when you “lose control.”
In modern life, emotional triggers like stress, anger, and anxiety can activate this response, even when there’s no real danger.
Fight or Flight Response
The amygdala activates your body’s fight-or-flight response automatically, without conscious thought.
Stress hormones are released when danger is perceived, which today can be triggered by everyday emotions like fear, stress, or aggression.
The Role of the Frontal Lobes
The frontal lobes regulate reasoning, planning, and voluntary actions.
While the amygdala reacts instantly, the frontal lobes take time to process and evaluate whether a threat is real.
In intense situations, the amygdala can override the frontal lobes, leading to impulsive reactions.
Mental Health and Amygdala
Conditions like chronic stress, anxiety, and PTSD (Post-Traumatic Stress Disorder) can increase amygdala activity.
This makes emotional regulation more difficult and increases the likelihood of frequent amygdala hijacks.
Symptoms of Amygdala Hijack
When your brain detects stress, it releases cortisol and adrenaline, preparing your body to fight or flee.
This leads to physical changes such as:
- Increased blood flow
- Expanded airways
- Higher blood sugar
- Pupil dilation
You may also experience:
- Rapid heartbeat
- Sweaty palms
- Clammy skin
- Goosebumps
During an amygdala hijack, irrational or inappropriate behavior is common.
Dealing with Amygdala Hijack
Although it happens automatically, you can regain control by activating your rational brain.
Start by acknowledging your body’s response. Recognize that your reaction is automatic, not always logical.
Once calm, reflect on what triggered the response.
Helpful techniques include:
- Deep, slow breathing to calm the nervous system
- Observing your emotional triggers
- Giving yourself time before reacting
Remember: stress hormones take about six seconds to dissipate. Focus on something positive during that time to regain control.
How to Prevent Amygdala Hijack
Prevention involves strengthening emotional intelligence—the ability to understand and manage emotions effectively.
Mindfulness
Mindfulness helps you stay present and aware without becoming overwhelmed.
It improves:
- Emotional awareness
- Self-control
- Understanding others’ emotions
Stress Management
Managing stress proactively reduces emotional overload.
Effective strategies include:
- Breathing exercises
- Regular physical activity
- Healthy daily habits
Seek Professional Help
If managing emotional responses feels difficult, seeking professional support can help.
A trained expert can guide you in developing emotional intelligence and coping strategies.
Final Thoughts
While the amygdala plays a crucial role in protecting us, it can sometimes overreact.
The good news is that with awareness, mindfulness, and practice, you can regain control and respond more calmly and rationally.
