(Editor's Note: Welcome to Part 3 of our Active Exposure Series! In Part 2, we covered how to handle a panic attack in the moment. Today, we focus on the long-term solution: Interoceptive Exposure. In this post, we take the mystery out of physical exposure therapy and show you step-by-step how facing safe body sensations retrains your brain's alarm system for good.)

If you’ve been living with sudden panic attacks, the idea of "exposure therapy" likely sounds like an unnecessary form of psychological torture. You might imagine a therapist pushing you into the very situations you fear most without a safety net.

In reality, interoceptive exposure doesn't happen on a highway or in a crowded auditorium—it begins safely in our session, either in my Roseville office or in the comfort of your own home during a virtual session. Instead of exposing you to external places, we gently expose you to the internal physical sensations that scare you—like a racing heart, dizziness, or chest tightness.

While exposure therapy works best under the guidance of a trained therapist, I want to pull back the curtain on what actually happens in these sessions. My goal is to demystify the process so you can decide if this approach is a good fit for you—and give you the confidence to take that next step and confront your fears.

Experimenting with Sensations

Sometimes it’s pretty clear what sensation we are going to target, but it always takes some experimenting on how to trigger the sensation. So, we will try a variety of activities to see which ones work. The experiment typically includes the following activities (plus others):

Hyperventilating- to trigger the sensation of lightheadedness, dizziness, tunnel vision

Breathing through a small straw- to trigger the sensation of difficulty breathing

Jumping jacks/ running in place- to trigger the sensation of a racing heart

During these sessions, after establishing safety, control, and making sure the client is game for the challenge, we start the experiments. I like to do these activities with my clients, as best as I can, while also keeping track of time and helping the client note what specific sensations they experience with each experiment as well as how anxious they are getting. I ask my clients to do each experiment for at least 60 seconds. Often by about 20 seconds, the client is getting pretty activated.

Once we identify the exercise that is triggering the most anxiety, we know this is the target. From here, we set up the homework. To be successful and see quick results, practicing the exposure every day is really key. It’s been my experience, and the experience of the experts that I’ve trained with, that the anxiety typically reduces within 1 week of practice if the exposure is done daily.

If you’re willing to face it head on, and willing to do your exposure homework with the intension of making yourself as anxious as possible, you’re likely to have success. If you skip days, do your exposure homework irregularly, or do it while multi-tasking, you’re just selling yourself short and going to experience all the discomfort with likely little success.

The Science: Re-Training the Amygdala

Interoceptive exposure is the gold-standard component of Panic Control Treatment (PCT), developed by Dr. David H. Barlow and Dr. Michelle G. Craske (Barlow and Craske).

When you have panic disorder, your brain has developed an interoceptive conditioning loop: it misinterprets neutral bodily changes (a spike in heart rate from coffee, or dizziness from bright fluorescent lights) as an imminent medical emergency.

By deliberately triggering these physical sensations in a controlled environment without engaging in "safety behaviors" (like checking your pulse or forcing deep breaths), we activate inhibitory learning (Craske et al.). Your brain builds a new memory track that overwrites the old fear loop: "My heart can beat fast without me collapsing."

3 Stages of an Interoceptive Exposure Session

We never jump into exercises blindly. A typical session follows a structured, collaborative protocol:

Safety Note: It is wise to consult with a doctor before trying any of these activities to make sure you are healthy/strong enough to do them safely.

  • 1. Mapping Your Specific Triggers and Safety Behaviors We start by identifying your body's specific "false alarm" signals. Are you most afraid of lightheadedness, racing heartbeats, shortness of breath, or feeling detached (derealization)? We map these out on a 0–100 distress scale. And what are you doing currently to try to make yourself feel better? It might be carrying water with you at all times, keeping medications with you, or even a mental mantra of “I’ll be okay”.

  • 2. The Controlled 60-Second Challenge We select one specific sensation and test it using a physical exercise. If you fear dizziness, we might spin in a comfortable swivel chair for 45 seconds. If you fear racing heartbeats, we might do running in place. Here we are testing which sensations trigger the anxiety.

  • 3. Avoiding Safety Behaviors We identify safety behaviors at the start so we know what to look out for. When doing these exposures, you will get the most benefit if you resist the urge to deploy "safety crutches"—no pulse-checking, no frantic breathing exercises, no water-chugging. We observe the physical sensation as objective scientists until the adrenaline naturally crests and falls on its own. Once the sensation has eased, stop to think about what you’ve learned. Did you learn that you’re not going to pass out even if you’re dizzy? Did you learn that actually this sensation becomes more annoying that frightening? Take time to connect what your body is feeling to your thoughts and beliefs.


Customized Practice Brings Fast Relief

Interoceptive exposure is never a "one-size-fits-all" process. We tailor every single exercise to match the exact physical feelings that trigger your panic—whether that means jogging in place to speed up your pulse, spinning gently in a chair to simulate dizziness, or breathing through a narrow straw.

Deliberately bringing on these physical sensations will push your boundaries, and it can feel intense or unpleasant in the beginning. That reaction is completely expected! The great news is that your brain rewires much faster than you might think. When you commit to practicing these short exercises daily as recommended, most people experience a dramatic drop in their panic levels within just a week. For me, a brief stretch of temporary discomfort is well worth getting my freedom back.

A Gentle Reframe

Instead of thinking, "Exposure therapy means forcing myself into terrifying situations," try this: "Interoceptive exposure is a controlled, scientific lab experiment where I test my body's true resilience in a completely safe space."

And remember, this isn’t about elimintating anxiety. Anxiety plays a very important role in survival. When you do feel anxious, remind yourself, “this is uncomfortable, but this isn’t dangerous”.

Medical Clearance for Exposure Exercises: Before attempting any exposure exercises—especially Interoceptive Exposure exercises that deliberately induce physical sensations (such as elevated heart rate, hyperventilation, or lightheadedness)—you must consult with a licensed medical physician or physician assistant to rule out underlying medical conditions. Interoceptive exposure should not be practiced without prior medical clearance if you have or suspect you have conditions including, but not limited to:

  • Cardiovascular disease, high blood pressure, or heart conditions

  • Asthma, COPD, or other respiratory disorders

  • Seizure disorders or epilepsy

  • Recent surgery, physical injury, or fainting disorders (syncope)

  • Pregnancy

Exposure therapy is most safely and effectively practiced under the direct guidance of a licensed mental health professional. If you experience severe distress, chest pain, shortness of breath, or a medical emergency, stop the exercise immediately and seek emergency medical care.

In Case of Emergency: If you are in crisis or experiencing a mental health emergency, please call or text 988 (the Suicide & Crisis Lifeline in the US) or go to your nearest emergency room.
