Amygdala Hijack Explained

Barbara Heffernan • February 19, 2025

Have you ever experienced an emotional reaction so intense that it completely overtakes your thoughts and feelings?

Understanding the Amygdala Hijack

These overwhelming moments—when you say or do things you later regret, or fail to speak or act when you should—are examples of what psychologists call an "amygdala hijack." This term describes when the fear center of your brain, responsible for your fight-flight-freeze response, commandeers your entire thought process, emotions, and behaviors.

This universal experience affects everyone at some point. Understanding the process can significantly help reduce your emotional reactivity.

In this article, I'll explain what an amygdala hijack is, why it happens, and how recognizing it can benefit you. Check in next week for a blog that will cover specific management techniques to help calm the amygdala hijack.

The Evolutionary Origins of Amygdala Response

From an evolutionary perspective, the amygdala is among the most ancient structures in our brain—one we share with most living creatures. Its primary function is triggering rapid responses to potential physical dangers, often before our conscious mind even processes the threat.

Consider this relatable scenario: you're walking along a path when something catches your peripheral vision that resembles a snake. Before you consciously identify the object, you've already jumped away—your autonomic nervous system responding instantaneously. Even after realizing it was merely a stick, residual activation keeps you on edge for several minutes. This quick response mechanism evolved to keep us safe from genuine threats where split-second reactions determined survival.

The sequence illustrates a fundamental aspect of our neurobiology: when we detect potential danger, our body reacts before the information reaches our frontal lobe for higher-level processing. In situations involving actual threats (like venomous snakes), this rapid response system is invaluable. The problem arises when this same system activates in modern contexts where immediate physical danger isn't present.

Here's where things get complicated for us modern humans: our amygdala cannot distinguish between physical threats (like predators) and psychological or social threats like criticism, rejection, or public speaking. Your brain processes a harsh comment from your boss, an argument with your spouse, or a challenging presentation with almost the same urgency as a tiger attack.

This evolutionary mismatch means our amygdala activates our emergency response system for situations that, while uncomfortable, don't actually endanger our physical survival. The amygdala's is designed to have this impact:

- Narrowing your focus to the perceived threat

- Flooding your system with adrenaline and stress hormones

- Directing blood flow toward large muscle groups

- Preparing you to fight, flee, or freeze

These responses, while lifesaving in true emergencies, can be counterproductive in everyday social interactions where thoughtful, measured responses would serve us better.

Recognizing Amygdala Hijack in Daily Life

Consider a workplace scenario: during a team meeting, a colleague criticizes your project. Although this situation requires careful listening and constructive engagement, your amygdala might interpret it as a threat. Suddenly, you find yourself flooded with stress hormones, your heart is racing and your thoughts are scattered. Instead of responding thoughtfully, you might:

> Lash out defensively (fight)

> Withdraw and avoid engaging (flight)

> Become paralyzed, unable to formulate a response (freeze)

Similarly, in a fight with a loved one, defensive or angry reactions can escalate the situation. The amygdala can hijack the prefrontal cortex, which is responsible for planning, risk assessment, and logical decision-making. In this state, even if you sound rational, your words may be cutting and unproductive. The amygdala can also shut down the part of the brain responsible for compassion and connection, leading to a lack of empathy. Once hijacked, rational communication becomes nearly impossible. If you're prone to freezing, you might become silent and unresponsive. If fighting is your default, you might make hurtful statements you'll regret later. If fleeing is your pattern, you might leave the discussion entirely, potentially worsening the situation if your partner is sensitive to abandonment.

The Neural Mechanics: How Hijack Affects Your Brain

During an amygdala hijack, your prefrontal cortex—responsible for planning, risk assessment, future thinking, and logical decision-making—becomes subordinated to your threat response system. Your cognitive abilities often remain active but serve only the amygdala's protective agenda rather than your long-term interests.

This explains why highly articulate individuals can sound remarkably rational during emotional arguments while actually making relationship-damaging statements. The prefrontal cortex provides the linguistic capabilities and logical structure, but the content and emotional tone derive from the amygdala's defensive positioning.

Importantly, amygdala hijack also suppresses brain regions associated with empathy and interpersonal connection. This explains why we lose our sense of relationship during heated conflicts—the neural circuitry for compassion becomes temporarily inaccessible. I often compare this state to reptilian responses: focused entirely on survival without the mammalian capacity for connection and nurturing. This loss of compassoin explains why amygdala hijacks can so severely damage our closest relationships.

Beyond "Fight": Hijacks Can include Freeze and Flight Responses

While discussions of amygdala hijacks often focus on aggressive outbursts (the fight response), it's crucial to recognize that freeze and flight responses also occur. Whether you become verbally aggressive, mentally check out of a conversation, or physically leave a difficult situation, the underlying mechanism is identical: your amygdala has taken control.

Understanding your typical pattern—fight, flight or freeze—provides valuable self-knowledge for managing emotional reactivity. Each pattern creates different relational challenges and requires specific interventions to address effectively.

The Role of Personal History in Amygdala Triggers

Through my twenty years as a psychotherapist and my personal journey, I've observed that most people develop very specific triggers based on their life experiences, particularly early childhood events. These triggers create emotional templates that get activated in seemingly unrelated situations.

For example, if you grew up with unpredictable or harsh authority figures, you might experience disproportionate anxiety or defensiveness with bosses, teachers, or other authority figures. Your emotional brain recognizes a pattern similarity

"authority figure = danger"

without accounting for the vast differences between your childhood circumstances and your current reality.

What makes these triggers so powerful is that emotional memory doesn't incorporate a sense of time or context. The emotional brain operates on pattern recognition, not logical analysis. It essentially says, "I've seen this pattern before, and it ended badly. I need to protect myself NOW!"

Relationships and Survival Response

Humans are fundamentally social creatures, wired to prioritize connection. Throughout our evolutionary history, belonging to a group significantly improved survival chances. Consequently, our brains process threats to important relationships as survival threats, even though they don't threaten immediate physical harm.

This explains why relationship conflicts can trigger such extreme reactions. When we perceive our connection with a loved one as threatened, our brain categorizes this as a survival emergency. The resulting amygdala hijack can make reasonable communication nearly impossible, creating a destructive cycle where both partners experience heightened threat responses.

This dynamic often intensifies with commitment level. Many couples notice that conflicts become more emotionally charged after marriage or similar commitment milestones. What previously might have been a manageable disagreement now feels catastrophic because the relationship itself represents security and survival.

Understanding and Managing Amygdala Hijacks

The term "amygdala hijack" was coined by Daniel Goleman in his influential book "Emotional Intelligence" to describe this universal human experience. The concept helps explain why smart, well-intentioned people sometimes behave in ways that undermine their relationships and objectives.

Learning to manage these responses—by recognizing triggers, calming physiological reactions, and developing self-regulation skills—forms a cornerstone of emotional intelligence. Understanding that our brains evolved with a negativity bias and automatic survival responses helps reduce self-judgment while motivating us to develop more adaptive patterns.

Our individual neurological wiring significantly reflects early conditioning experiences, but thanks to neuroplasticity, we can reshape these patterns. Through consistent practice with evidence-based techniques, we can actually rewire our emotional responses and reduce the frequency and intensity of amygdala hijacks. This capacity for neurological change underlies all effective emotional regulation approaches.

My free webinar, Rewire Your Brain for Joy and Confidence , explains how our behaviors, thoughts, and emotions are wired together through repetition and provides hope and practical tools for how to re-wire our brains through altering our thoughts and behaviors.

Moving Forward: Increasing Awareness and Control

Recognizing when an amygdala hijack occurs marks an essential first step toward managing this response. In my next article, I'll explore specific techniques for:

1. Identifying personal triggers before they activate

2. Reducing physiological arousal during emotional reactions

3. Reconnecting with the rational brain during stressful situations

4. Rewiring emotional responses through consistent practice

5. Building resilience to prevent future hijacks

The goal isn't eliminating emotional responses—they provide valuable information and motivation. Rather, the objective is developing sufficient awareness and self-regulation skills to prevent automatic reactions from overtaking rational choices and damaging important relationships.

Conclusion: The Path to Emotional Regulation

The amygdala hijack represents a normal neural process that evolved to protect us from physical dangers. In contemporary life, however, this same response often creates more problems than it solves. By understanding the neurobiological basis of emotional reactivity, we can approach our triggered moments with greater compassion and implement effective strategies for regaining control.

Remember that emotional regulation is a skill developed through practice. With consistent effort and appropriate techniques, you can significantly reduce the frequency and intensity of amygdala hijacks, leading to improved relationships, better decision-making, and greater overall well-being.

Emotional Regulation and Relationships: 5 Critical Skills to Improve Relationships

By Barbara Heffernan • April 3, 2026

You can probably recall a time when you were with someone who was intensely anxious—and within minutes, you began to feel anxious yourself. Perhaps your heart rate increased. Your breathing became shallow. The knot in your stomach tightened. Or maybe you remember the opposite: a time when you were with someone who was truly grounded and calm, and their presence actually calmed you down. Your shoulders dropped. Your breathing deepened. The tension you had been carrying began to dissipate. This is not your imagination. This is emotional contagion, and it is scientifically proven. Understanding how your own emotional regulation—or lack thereof—impacts other people, and how other people's emotional states impact you, is essential for healthy relationships. Learning emotional regulation tools can improve your relationships significantly. Learning how to lower your susceptibility to emotional contagion can help as well. In this article, I will explain what emotional contagion is, how it impacts relationships, and provide five specific strategies for improving regulation in your own relationships. What Is Emotional Contagion? Emotions are contagious. Extensive research—both behavioral research and neuroscience—shows that we pick up the emotions of the people around us. The closer our relationship with them and the more invested we are in that relationship, the more this phenomenon occurs. This may not always feel accurate because we also tend to balance each other out. If someone is very upset, we might suppress our own emotions in response. But as I will explain, that suppression is actually part of the same dynamic. Three Pathways to Emotional Contagion There are three pathways that lead to emotional contagion: Pathway 1: Automatic Mimicry Unconsciously, when we see facial expressions in another person, we mimic them. If someone smiles, we tend to smile immediately. If someone frowns, we might make the same expression. This happens not just with facial expressions but also with voice, tone and body posture. Pathway 2: Autonomic Mimicry This involves our autonomic physiological system which works in synchrony with other people. Our heart rate, our breathing rhythm, and even our pupil dilation tend to mimic each other. Our nervous systems influence each other constantly. Pathway 3: Affective Convergence This is the convergence of feelings. When our facial expressions and body posture mimic another person's, and our physiological system aligns with theirs, we develop the same affective feelings. We end up experiencing a version of that emotion ourselves. The Suppression Trap: Why "Staying Calm" Can Make Things Worse If someone is extremely upset, you might calm way down. If this happens almost automatically, you are probably suppressing your emotions rather than regulating them. Extensive research shows that when one person suppresses their emotions, it actually makes the other person more anxious. And the person who is suppressing—while they might appear calm externally - is experiencing all the physiological signs and symptoms of anxiety or a heightened emotional state. Even when we are trying to be the balance in the room, we might actually be escalating the emotions present. This is particularly true for those who grew up parentified. Adults who were parentified as children often feel their emotional regulation is better than anyone else's in their families. While that might be true to some extent, without substantial self-awareness and genuine emotional regulation tools, you are likely using emotional suppression, not regulation. Where Emotional Regulation Patterns Come From The means by which you emotionally regulate—and whether you are highly regulated or highly dysregulated—is largely due to how you were raised. I am not saying this to assign blame, nor do I want you to spiral into worry about what you may have done to your own children. These are intergenerational patterns, and all we can do is work with the present. However, it can help to recognize that if you feel your own emotional regulation is lacking, you probably learned from dysregulated caregivers. If you have a partner who is very dysregulated, the same is likely true for them. This understanding allows us to remove blame and accusation from the discussion. We can approach this with compassion, recognizing that these are skills that should perhaps be taught in school or more seriously in our society—but they are not. The good news is that you can learn them now. Five Practical Tools to Improve Emotional Regulation in Your Relationships It truly is possible to improve your own emotional regulation and have a postiive impact on your relationships. These tools are helpful even for the partner that feels they are the one who is more emotionally regulated. And as a heads up, Tools 1 and 5 require substantial work - but gradual improvement is helpful! Tools 2, 3, and 4 are easier to implement immediately. Tool 1: Develop Your Emotional Boundaries Because emotional contagion is so strong—particularly if you grew up in a caretaker role in your family—it is important to begin recognizing when the emotions you are feeling are the ones you are absorbing from someone else. Begin to visualize a see-through bubble around you which represents you and your emotional boundary. Begin to think of your emotions as existing within that bubble. And picture another bubble around the other person - give it a light, see-through color. Picture that all their emotions are within their bubble. Differentiate between what you are feeling and what they are feeling. Bring in your observer brain to look at what you are feeling. For example... "Wait a second. I am feeling anxious because my partner is anxious about their interview tomorrow. What is my anxiety about?" You can begin to see whether your anxiety is about getting them to calm down so they can perform well in their interview. Perhaps you don't want them to be disappointed, or you have a vested interest in them getting a job. Once you understand why you are feeling anxious, you can apply tools to reduce your own anxiety, rather than focus on theirs. Because if we get anxious about making sure someone else is not anxious, it simply escalates the anxiety in the room. Part of developing emotional boundaries is understanding that other people's emotions are not ours to solve. We can be empathetic without feeling responsible for calming the other person down or changing their emotional state. Your observer brain can help you think through, "I do not have to convince them. I can recognize the impact their emotional state has on me, but I do not have to spiral into desperately trying to fix something I cannot fix." Tool 2: Use Your Breathing Deliberately If you learn diaphragmatic breathing and use it during difficult moments in relationships, you can keep your physiology within a tolerable range. In EMDR therapy, there is a concept of keeping your emotions within a "window of tolerance." They can still fluctuate, but you remain relatively regulated throughout. Diaphragmatic breathing is a powerful way to help yourself do that. When you breathe in a calm, regular manner, it is actually helpful to the other person as well. Your regulated physiology can support theirs. Tool 3: Establish a Guideline for Taking Breaks Put in place for yourself a boundary about taking a break from a conversation if you become too emotionally dysregulated. What typically happens in couple relationships (and I saw this extensively during 20 years of couples counseling) is that one person is visibly out of control upset, and the other says, "We need to take a break until you calm down" (and there's usually a finger point that goes along with the "you"). Generally, this escalates the emotions in the room. In actuality, even if you are the one who appears less upset externally, you are probably very physiologically activated internally. There is a marriage and family therapist and researcher who has a rule: if your pulse rate is 10% above its normal resting rate ), you need to take a break. ( John Gottman, PhD, Seven Principles for Making Marriage Work ) The problem with telling the other person they need a break to calm down is that it will make things worse. It feels like criticism and attack. It makes someone defensive. It increases their fight-flight-freeze response. Instead, say: "I am having a hard time regulating myself in this moment. Can we take a 10-minute break? I will be right back. I just need 10 minutes to do some slow breathing. We can set our alarm." You must put a time frame on it. Take a five-minute break, a 10-minute break, or if you are extremely dysregulated, revisit the conversation in the morning. Without a time frame, the other person will feel abandoned, which escalates their emotional dysregulation. You may also be feeding into your flight mode—your reactive pattern of running away from conflict. Set the boundary for yourself, not for the other person: "If I get too upset, I will take a mini timeout to calm myself down." I recognize this does not work in every situation. You cannot simply walk away from a young child. But you can incorporate this thinking to develop creative strategies of your own. Tool 4: Validate Before You Fix or Problem-Solve One of the most regulating things you can do for someone else is help them feel truly heard. Acknowledging their emotional experience before moving to "let's fix this and problem-solve" will de-escalate their emotional response and prevent the conversation from escalating out of control. I know I said you are not in charge of their emotional regulation—and you are not. However, knowing strategies that benefit the relationship benefits you. These are basic relational tools. If you have a partner who has difficulty validating your emotions, and you are emotionally regulated, you can say: "I am very upset about this, but I do not want to jump into problem-solving. I simply want to feel heard." There is an element where we sometimes have to help train people how to be in relationship with us. If you are in couples counseling with a therapist facilitating this, excellent. But if you are not, sometimes it helps to explain these concepts to your partner. Let them know what will help you calm down when you are upset. You might have to remind them, and I know that takes substantial emotional regulation on your part. But honestly, that is the big picture here: the best thing you can do for your relationships with others—as well as your relationship with yourself—is learn emotional regulation tools. Tool 5: Practice Honest, Regulated Communication This can be understood as assertive communication that is also compassionate. If you are feeling overwhelmed, I understand. These concepts can seem complex and somewhat unattainable. I have an online boundary program that addresses emotional regulation as the foundation for healthy boundaries. It includes an exercise on visualizing emotional boundaries to strengthen that skill, and an entire section on assertive communication so you can set and maintain boundaries. Healthy boundaries are not about keeping people away or controlling other people's behavior. Healthy relationships actually require good boundaries. Good boundaries are about knowing yourself—where you end and the other person begins—and knowing it is acceptable for you to have needs. Compassionate, assertive expression of whatever needs to be communicated will help the relationship. It can be done in a way that supports your own emotional regulation and possibly helps the other person—or at minimum, does not contribute to escalation. Suppressing your own emotions and needs will escalate the negative cycle of conversation. This is not about suppression. It is definitely not about lashing out, exploding, or releasing everything you have been suppressing because you are angry and frustrated. If you have taken that timeout when needed, if you have been aware ("my heart rate is way up; I am in fight-flight-freeze mode"), you will not reach that explosion point because you will have taken your break and calmed down. All these steps are interrelated. Expressing what you feel in a regulated manner keeps you in connection with the other person. Remember: it is not just what you say but how you say it, and even how you are feeling when you say it. A statement like "I am feeling overwhelmed right now with too much to do" will enable you to stay in connection far more effectively than exploding because your partner has not done what they were supposed to do. Anytime we explode with attack or criticism, we contribute to emotional dysregulation in the room. Bringing It All Together Consciously keep track of your own emotional regulation Visualize your emotional boundary Use breathing techniques to stay within your window of tolerance, aware that you might need to take a mini timeout for yourself if you cannot stay within that window Validate the other person's feelings, emotions, and experience. Pay attention to: "This is me and my emotions, and that is them and theirs." Practice assertive communication which includes compassion for yourself and the other person This is not easy work. I know that. But what I want you to understand is that emotional contagion is real, and there are tools you can use to work with it. You can understand the other person without fully absorbing their emotional state. We are not individual emotional islands. Each one of us impacts those around us. Let me be very clear: Impacting others is not the same as causing their emotions or being responsible for their emotions. They are not responsible for ours. We are responsible for our own emotions and what we do with them. Yet there is this framework of interconnectedness among us, and knowing how to work with it can improve your life and your relationships significantly.
