Interoceptive Exposure: A Powerful Technique for Anxiety

Barbara Heffernan • June 4, 2026

Interoceptive exposure can be transformative for people with somatic anxiety, specifically panic attacks, PTSD, OCD and health anxiety.


Your physical symptoms may have become a significant trigger for your anxiety, perhaps even the primary trigger. Or your physical symptoms might contribute to sustaining your anxiety cycle because they cause you to do what you can to avoid the sensations and the situations that cause those sensations.


These sensations can include a racing heart, stomach ache, palpitations, or noticing a strange pain somewhere in your body. When these physical sensations are interpreted as danger, your natural inclination is to avoid them and become distressed when they appear.


Interoceptive exposure is essentially exposure to your own internal symptoms. "Interoceptive" means looking inside—it's awareness of what's happening in your body. This technique is used in Cognitive Behavioral Therapy (CBT), where you intentionally recreate some of those symptoms in a safe environment with a therapist. Like any exposure therapy, if you can tolerate the anxiety and sit through it, the panic you feel from those symptoms will gradually decrease.


Through this process, your old brain—your amygdala and nervous system—learns that these sensations are actually not dangerous.


How Interoceptive Exposure Works in Clinical Settings


In a clinical setting, the therapist and client identify which physical sensations contribute to anxiety spikes. They then brainstorm ways to recreate those physical symptoms in the therapist's office.


For example, if shortness of breath and a spike in your pulse rate or racing heart are triggers, you might run in place for 30 seconds as fast as you can to recreate those symptoms. As you feel them, the therapist will ask, "How distressing is that to you on a scale of 0 to 10?" We use the term Subjective Units of Distress, or SUDS for short, to measure how upsetting a feeling is to you.


In my clinical practice over twenty years, I worked with many clients with PTSD and cPTSD. When clients revisit traumatic memories or upsetting events, they often begin to re-experience the physical sensations of the trauma simply by thinking of those memories. The link between the trauma and the physical sensations is often very upsetting.

I found EMDR therapy (Eye Movement Desensitization and Reprocessing) highly effective in helping clients recover from PTSD and cPTSD. EMDR therapy utilizes the concepts of Interoceptive Exposure by helping the clients sit with the physical and emotional feelings tied to the trauma. As the client would experience these emotions with more tolerance of the anxiety they cause, and more curiosity, the feelings generally waned. And how upsetting those feelings were would also wane.


This process involves mindfulness—being mindfully aware of physical sensations, noticing them without judgment, and allowing yourself to truly feel them without feeling compelled to make them stop. Over time, clients develop a greater sense of "I can handle this. It's okay. My heart races and then it calms down."


Research-Backed Effectiveness


The concept of exposure—not avoiding what you're afraid of—is a common theme throughout almost all anxiety recovery. Interoceptive exposure was originally developed for panic disorder, and extensive research shows it is extremely effective for this condition.


Various techniques have been used in research and clinical settings, such as having clients spin in a chair to evoke dizziness if that is a trigger, or breathing through a narrow straw to evoke the feeling of not getting enough air.


Even hearing about these techniques might make you feel anxious because the fear of those physical sensations is so strong. However, in various research projects, there were really no adverse effects on people from doing this, even though many people were initially afraid to attempt it.


Applications Across Different Conditions


I've discussed how this applies to PTSD when physical sensations are linked to trauma. This technique helps those two things become decoupled or separated.


Interoceptive exposure (IE) is now also being incorporated into OCD treatment more frequently because much of OCD is triggered by some type of internal sensation. It could be an uncomfortable physical sensation or an urge, and then that urge begins the cycle for someone with OCD.


How to Apply These Principles on Your Own


You can utilize these principles even if you're not in formal therapy. Here's how to begin:


Start Gradually


Begin with some of the lower-intensity physical sensations, not necessarily the ones that cause the biggest anxiety spike. This gives you time to practice.


Create a Sensation Inventory


Write a list of which different physical sensations trigger anxiety, then rank them. Pick one or two to work with.

Notice


Notice when the physical sensation arises and pause before you try to jump away from it.


Approach with Curiosity


Approach the sensation with curiosity:

  • What does that physical sensation feel like?
  • Where are you feeling it in your body?
  • If it had a color, what color would it be?
  • Is it hot? Is it cold?


Notice the Thoughts and Separate


Notice what thoughts this physical sensation links to. Perhaps jot the thoughts down. See if you can  separate the observation of the feeling from the thoughts. 


Slow Things Down and Notice if the Physical Sensation Changes


By slowing things down and separating the physical sensation from thoughts about its danger, you create space for new learning. As you observe the physical sensation, notice if it's changing. Does it change as you pay attention to it?


Try to Reframe Your Thoughts About the Feeling

Try to move toward the feeling of "I can feel this sensation and also know that I'm safe enough." If you can stay present with these sensations, they will calm down.


This will help your old brain update its assessment of that feeling.

Expect Initial Challenges


As you begin to try to sit with these feelings, you might notice that your anxiety increases initially. One of the hardest aspects of all exposure therapy is that when you allow yourself to be exposed to things you're afraid of and have been pushing away, it does create a spike in anxiety. This is actually why many people drop out of exposure therapy—it feels too intense.


However, increasing your tolerance for feeling the anxiety is what provides long-term relief.


Additional Resources


I offer a free webinar called "Rewire Your Brain for Joy and Confidence." In it, I discuss some of the best tools for beginning to rewire the pathways that have developed—pathways that have likely been forming since childhood. These pathways tie certain physical responses to events and situations in ways that can sustain the pain of those events.


I also have videos on avoidance and why avoidance makes anxiety worse. If you're working with a therapist, they may not have heard of the concept of Interoceptive Exposure using these exact terms, but they might be willing to look into it and see if they're comfortable working with you on some of this.

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.
