What is a panic attack and why does it generate so much fear?
A panic attack is a sudden, intense episode of extreme fear that appears without warning and without a real danger to justify it. During an attack, the sympathetic nervous system activates the fight-or-flight response in a disproportionate way, flooding the body with adrenaline and cortisol and producing an avalanche of physical symptoms that the person interprets — mistakenly — as signs of imminent danger.
What makes panic attacks so terrifying is not only the intensity of the symptoms, but the catastrophic interpretation the person makes of them: "I'm having a heart attack," "I'm going to die," "I'm losing control." This interpretation amplifies physiological activation and creates a vicious cycle that feeds on itself in a matter of seconds.
I'm Xènia Capel Salcedo, a licensed health psychologist registered with the COPC under number 14982. I offer online panic attack therapy by video call with techniques based on scientific evidence. In this article I explain how panic disorder works, why online therapy is an especially effective format for treating it, and how I can help you regain control of your life.
Symptoms of a panic attack: what your body feels
The symptoms of a panic attack reach their peak in approximately 10 minutes and usually last between 15 and 30 minutes in total, although the subjective sensation can make them feel much longer. They may include:
Physical symptoms
- Intense rapid heartbeat: the heart pounds so hard it feels like it's "going to jump out of your chest"
- Chest pain or tightness: often confused with a heart attack
- Difficulty breathing: feeling of suffocation, as if air "won't come in"
- Dizziness and unsteadiness: caused by hyperventilation
- Sudden cold or hot sweating
- Trembling in the hands, legs or whole body
- Nausea or gastrointestinal discomfort
- Numbness or tingling in the hands, feet or face (paresthesia)
- Sensation of intense heat or sudden chills
Psychological symptoms
- Intense fear of dying: conviction that you are suffering a serious medical problem
- Derealization: feeling that the world is not real, as if you were seeing it through glass
- Depersonalization: feeling separated from your own body, like an outside observer
- Fear of "going crazy" or completely losing control
- Urgent, overwhelming need to flee the place where you are
All these symptoms, however terrifying they may be, are not dangerous to your health. They are the result of an intense activation of the autonomic nervous system and disappear when the body returns to its baseline state. Understanding this is the first step in breaking the panic cycle.
Isolated panic attacks vs. Panic Disorder
It's important to distinguish between experiencing an isolated panic attack and having a panic disorder. Approximately 11% of the general population experiences at least one panic attack during their lifetime. In many cases it is a single episode linked to a moment of intense stress.
Panic disorder, on the other hand, is diagnosed when:
- The panic attacks are recurrent and unexpected (at least some of them come without a clear trigger)
- The person develops a persistent worry about having further attacks (anticipatory anxiety)
- There are significant changes in behavior aimed at avoiding attacks (avoidance of places, situations or activities)
This anticipatory anxiety — the fear of fear — is often the most disabling part of the disorder. The person lives in a state of constant hypervigilance, scanning their bodily sensations for any sign that might announce a new attack.
The relationship between panic and agoraphobia
Up to 50% of people with panic disorder develop some degree of agoraphobia: the fear or avoidance of situations from which it would be difficult to escape or get help if a panic attack occurred. The most typically avoided situations include:
- Public transport (subway, bus, train)
- Open spaces (parking lots, bridges, squares)
- Enclosed spaces (elevators, cinemas, tunnels)
- Queues or crowds
- Being away from home alone
Agoraphobia can range from mild discomfort to a total inability to leave the house. In the most severe cases, the person becomes literally trapped at home. Paradoxically, the online therapy format is especially valuable in these cases, since it allows treatment to start without the obstacle of having to leave home.
Clark's cognitive model: why panic attacks are maintained
Clark's cognitive model (1986) is the main theoretical reference for understanding the maintenance of panic disorder. According to this model, panic attacks happen through a four-phase cycle:
- Initial activation: a normal or slightly unusual bodily sensation (a palpitation, slight dizziness, chest tightness from posture) is perceived
- Catastrophic interpretation: the sensation is interpreted as a sign of imminent danger ("I'm having a heart attack," "I'm going to faint," "I'm losing control")
- Increased anxiety: the catastrophic interpretation generates fear, which further activates the sympathetic nervous system
- Symptom intensification: physiological activation produces more symptoms (more rapid heartbeat, more difficulty breathing), which "confirm" the catastrophic interpretation
Breaking this vicious cycle is the central goal of cognitive behavioral therapy for panic. And the good news is that it can be done with great effectiveness in an online format.
Panic attack vs. heart problem: how to tell them apart
One of the most frequent fears among people who suffer panic attacks is confusing an attack with a real cardiac problem. This concern is understandable, but there are key differences:
Panic attack
- Chest pain tends to be sharp, stabbing or localized in a specific spot
- Symptoms reach their peak in 10 minutes and then subside
- The pain changes with posture or breathing
- Usually accompanied by tingling in the hands and a sense of derealization
- Improves with relaxation and controlled breathing
Heart problem
- The pain is usually oppressive, like a weight on the chest
- Radiates to the left arm, jaw or back
- Does not improve with relaxation or by changing posture
- May appear during physical exertion
- Is not accompanied by depersonalization or derealization
Important: if it's your first episode or you have any doubt, go to an emergency service to rule out organic causes. Once panic is confirmed, psychological therapy is the first-line treatment.
How online panic attack therapy works
Online panic attack therapy follows the same validated clinical protocols as in-person therapy, adapted to the video-call format. The process consists of several phases:
• Assessment and psychoeducation (sessions 1-2): We explore your history with panic: when the attacks started, what symptoms you experience, how you interpret them, and what avoidance behaviors you have developed. I provide you with a complete understanding of the panic mechanism based on Clark's model, so you understand exactly what is happening in your body and why. This understanding alone significantly reduces anxiety.
• Cognitive restructuring (sessions 3-5): We identify and challenge your catastrophic interpretations. You'll learn to recognize the automatic thoughts that fuel panic ("this is a heart attack," "I'm going to die") and replace them with interpretations more in line with reality ("my heart is racing because I'm anxious, not because I have a cardiac problem").
• Interoceptive exposure (sessions 5-10): This is the most transformative phase of the treatment. We deliberately provoke the physical sensations you associate with panic — rapid heartbeat, dizziness, hyperventilation — so you can verify that they are not dangerous. I guide you step by step by video call as you do specific exercises.
• Exposure to avoided situations (sessions 8-14): If you have developed agoraphobia or avoid certain situations, we design a hierarchy of gradual exposures. I can accompany you in real time by video call during some of them.
• Relapse prevention (final sessions): We consolidate the tools you've learned and prepare you to manage possible moments of anxiety reactivation autonomously in the future.
Online interoceptive exposure: how it's done
Interoceptive exposure is the star technique in panic treatment and works perfectly in an online format. It consists of deliberately provoking the feared sensations in a safe and controlled environment, so that the brain learns that they pose no danger.
Examples of interoceptive exercises we do online
- Controlled hyperventilation (30 seconds): produces dizziness and tingling to desensitize you to these sensations
- Breathing through a straw: generates a controlled feeling of breathing difficulty
- Spinning in a chair (30 seconds): produces dizziness and disorientation
- Going up and down stairs quickly: generates natural rapid heartbeat and hyperventilation
- Holding your breath (30 seconds): produces a feeling of suffocation
- Staring at a fixed point for 2 minutes: can generate a sense of derealization
- Tensing all the muscles in the body for 1 minute: generates trembling and a feeling of weakness
Each exercise is first done with my guidance by video call and then as a between-session task, repeating it until the sensations no longer generate fear. The online format is ideal because you are in your usual environment, which makes the practice feel natural.
Cognitive restructuring: changing the interpretation of panic
Cognitive restructuring is the other key piece of treatment. The goal is to identify the automatic catastrophic interpretations that trigger and maintain the panic cycle and replace them with thoughts that are more in line with reality.
For example, we work with thoughts like:
• "If my heart is pounding hard, it means I have a heart problem" → "My heart is pounding because my nervous system has activated. It's a normal anxiety response that will pass in a few minutes."
• "If I'm dizzy, I'm going to faint" → "Dizziness is caused by hyperventilation. Since I started having panic attacks, I have never fainted. People with panic actually have blood flow rising, not dropping."
• "I'm losing control, I'm going to go crazy" → "People who 'go crazy' don't fear going crazy. My fear is a sign that my brain is working perfectly."
In the online format, I can share my screen to show you diagrams of the cognitive model, thought-record worksheets and visual schemas that greatly facilitate this work.
Breathing techniques for panic
Hyperventilation (breathing too fast or too deeply) is a key factor in the escalation of panic attacks. When you hyperventilate, you exhale too much CO₂ and the pH of your blood shifts, causing dizziness, tingling and a feeling of unreality — symptoms that, in turn, generate more fear.
Controlled diaphragmatic breathing
I'll teach you the slow diaphragmatic breathing technique, which activates the parasympathetic nervous system and stops the panic from escalating:
- Breathe in through your nose for 4 seconds, filling your abdomen (not your chest)
- Hold the air for 2 seconds
- Exhale slowly through your mouth for 6 seconds
- Repeat for 3-5 minutes or until activation decreases
The key is not to use it during the attack (in the middle of panic it's very hard to control your breathing), but to practice it daily so that your nervous system gets used to being regulated and becomes less reactive to triggers.
Important: breathing is a complementary tool, not the main treatment. If you only work on breathing without doing interoceptive exposure and cognitive restructuring, the attacks are likely to come back. Breathing can become a "safety behavior" that maintains the disorder if it is not used correctly within the therapeutic framework.
Why online therapy works especially well for panic
Online panic attack therapy is not simply an acceptable alternative to in-person therapy: in many ways it is an especially appropriate format for this disorder. The reasons are many:
• Removes the agoraphobia barrier: Many people with panic disorder avoid leaving the house or commuting, which means they often never make it to a practice. Online therapy completely removes this obstacle.
• Real environment for exposure: Interoceptive exposure done from home is more ecological (closer to real life) than that done in a clinical office. The sensations we provoke are experienced in your everyday context, which makes generalization easier.
• Reduces safety behaviors: Many people with panic need to be accompanied to places. Online therapy lets you work autonomously from the start.
• Real-time exposures: I can accompany you by video call while you do an exposure at the supermarket, on public transport or in the street, without a therapist needing to physically follow you.
• Treatment consistency: Regularity is key in panic treatment. The online format makes it easier to keep sessions consistent without interruptions caused by travel, illness or other unforeseen events.
What the first online panic therapy session is like
If you've never done online therapy — or therapy at all — it's natural to have doubts and a bit of nervousness. This is how the first session usually works:
• Connection: I send you a secure video-call link. You'll need a quiet space, a stable internet connection and a device with a camera and microphone.
• Getting acquainted (10 min): We start with an informal conversation so you feel comfortable. I explain how therapy works, the confidentiality framework, and we resolve any doubts.
• Exploring the reason for consultation (25 min): You tell me about your experience with panic attacks: when they started, how often they happen, what symptoms you experience, how you interpret them, what situations you avoid, and how they affect your life.
• Initial psychoeducation (15 min): I provide you with a first explanation of the panic mechanism, so you understand what is happening in your body and why. This understanding alone usually generates significant relief.
• Initial plan (5 min): We define the goals of therapy and I propose a work plan tailored to your case. I leave you with a small task to do before the next session.
When to seek professional help for panic attacks
Consult a psychologist specialized in panic if:
- You have had more than one panic attack in the past few weeks
- You live with the constant fear that another attack will happen
- You avoid situations for fear of having an attack (transport, queues, enclosed spaces, going out alone)
- You have stopped doing activities you used to enjoy for fear of panic
- You constantly check your physical state (taking your pulse, measuring blood pressure, going to emergencies repeatedly)
- Anticipatory anxiety affects your work, relationships or quality of life
- You use alcohol, non-prescribed medication or other substances to calm anxiety
Panic disorder is one of the anxiety disorders with the best prognosis. With the right treatment, the vast majority of people experience significant and lasting improvement.
