The fear of fear is a real psychological phenomenon where a person becomes afraid of their own anxiety responses. Known clinically as phobophobia, it involves dreading the physical sensations that come with being scared, such as a racing heart, sweaty palms, shortness of breath, or dizziness. For some people, the anxiety of anticipating fear actually becomes a phobia itself, creating a self-reinforcing cycle that can escalate into panic attacks and significant avoidance of everyday life.
How the Fear of Fear Works
At its core, the fear of fear is a problem of misinterpretation. When you feel anxious, your body produces normal stress responses: your heart beats faster, your breathing quickens, your muscles tense. Under ordinary circumstances, these sensations fade on their own once the perceived threat passes. But if you start worrying intensely about what those sensations mean before they subside, you add fuel to the fire. Your anxiety about being anxious makes the sensations stronger, which increases your alarm, which intensifies the sensations further.
This feedback loop can escalate so quickly that it triggers a full panic attack in seconds. Someone might feel their heart rate climb slightly and interpret it as a sign of a heart attack. Or they notice dizziness and become convinced they’re about to faint or lose control. These are called catastrophic misinterpretations: normal bodily signals read as evidence of immediate danger. The sensations themselves aren’t harmful, but the belief that they are keeps the cycle spinning.
Over time, this pattern trains your nervous system to treat its own alarm signals as threats. A racing heart, which once just meant you were startled or exerted yourself, becomes something to fear in its own right. Psychologists call this interoceptive conditioning: internal body cues like a pounding chest get paired with the memory of a panic attack, so the next time your heart speeds up for any reason, your brain sounds the alarm again.
Anxiety Sensitivity: The Underlying Trait
Not everyone who feels anxious develops a fear of fear. The difference often comes down to a trait called anxiety sensitivity. This is the tendency to believe that the experience of anxiety itself will cause harm, whether physical illness, embarrassment, or even more anxiety. A person with high anxiety sensitivity doesn’t just dislike feeling nervous. They believe something bad will happen because they feel nervous.
Researchers describe this as having two layers. The first is expecting that a situation will make you anxious. The second, deeper layer is believing that the anxiety itself is dangerous. Someone with low anxiety sensitivity might notice their heart racing before a presentation, shrug it off, and move on. Someone with high anxiety sensitivity notices the same racing heart and thinks: “Something is wrong with me. This feeling could spiral out of control.” That second belief is what transforms ordinary nervousness into a fear of fear.
This trait is considered a risk factor for developing anxiety disorders more broadly. It doesn’t guarantee someone will develop phobophobia or panic disorder, but it makes the fear-of-fear cycle much easier to trigger and much harder to break without intervention.
What It Feels Like Day to Day
People with phobophobia often describe a constant state of monitoring. They scan their body for early signs of anxiety the way someone with health anxiety checks for lumps or pains. A slight flutter in the chest, a moment of lightheadedness, a warm flush across the face: any of these can set off a wave of dread. The fear isn’t about a spider, a height, or a social situation. It’s about the feeling of fear itself and what it might do to them.
Some people worry specifically about developing a new phobia. They might avoid situations where a phobia could theoretically take hold, steering clear of elevators, crowds, or medical settings not because they’re already afraid of those things, but because they’re afraid of becoming afraid. Others focus more on the physical side, convinced that the shortness of breath or chest tightness that accompanies anxiety could cause lasting damage.
This kind of vigilance is exhausting, and it tends to shrink a person’s world. The avoidance can look a lot like agoraphobia, where someone stops going to places associated with past panic attacks. If you once had a panic attack in a grocery store, you might avoid grocery stores entirely. Not because the store itself is frightening, but because the environment triggers the memory of panic, which triggers the fear of it happening again, which starts producing the very sensations you’re trying to avoid.
Connection to Panic Disorder
The fear of fear is so central to panic disorder that it appears directly in the diagnostic criteria. To meet the clinical threshold, a person must experience recurrent panic attacks followed by at least one month of persistent worry about having more attacks, worry about the consequences of attacks (like losing control), or significant changes in behavior designed to avoid future attacks. In other words, it’s not just the panic attacks that define the disorder. It’s the fear of the next one.
This distinction matters because many people experience an isolated panic attack at some point in their lives without ever developing panic disorder. What separates a single scary episode from an ongoing condition is precisely this fear-of-fear response: whether the person begins dreading and reorganizing their life around the possibility of it happening again.
How Treatment Breaks the Cycle
The most effective approach for dismantling the fear of fear is cognitive behavioral therapy, which works on both the thought patterns and the physical responses simultaneously. On the cognitive side, a therapist helps you identify the catastrophic interpretations you’re making (“my racing heart means I’m having a heart attack”) and test them against reality. On the behavioral side, the goal is gradual, controlled exposure to the feared sensations themselves.
This second part, called interoceptive exposure, is particularly important for phobophobia because the feared object isn’t something external you can simply approach, like a dog or a bridge. It’s your own body’s stress response. So treatment deliberately recreates those sensations in a safe setting. Common exercises include breathing rapidly and deeply for one minute to mimic hyperventilation, spinning in a chair to produce dizziness, running in place to raise your heart rate, or breathing through a narrow straw while holding your nose to simulate the feeling of restricted airflow. Shaking your head side to side for 30 seconds can reproduce the lightheadedness that often triggers alarm.
The purpose isn’t to be unpleasant for its own sake. Each exercise teaches your nervous system that these sensations are uncomfortable but not dangerous. Over repeated practice, the automatic fear response to a racing heart or dizzy spell weakens. You learn, at a level deeper than logic, that the sensations peak and then pass without the catastrophe you expected.
Research on CBT for phobias shows strong results, with some studies finding that even a single extended therapy session can be as effective as multi-session treatment for certain phobias in young people. For panic disorder specifically, the combination of cognitive restructuring and interoceptive exposure has decades of evidence behind it. The cycle that feels unbreakable while you’re inside it turns out to be surprisingly responsive to systematic intervention.
