Understanding Health Anxiety: How CBT Can Help
It is completely understandable to notice changes in your body and want reassurance that everything is okay. Most people worry about their health from time to time, especially when they experience new symptoms, are under stress, or have had a recent illness in the family. Health anxiety becomes more of a problem when these worries become persistent, distressing, and hard to switch off, even after medical reassurance.
What is health anxiety?
Health anxiety involves a strong fear that you may be seriously unwell, or could become unwell, despite little or no medical evidence of a serious illness. It can lead people to become highly focused on normal bodily sensations, such as headaches, stomach discomfort, dizziness, or changes in breathing, and interpret them as signs of something dangerous. Ironically, anxiety itself can cause physical symptoms, which then fuels even more worry.
For some people, health anxiety shows up as repeated body checking, frequent internet searching, repeated medical appointments, or asking loved ones for reassurance. For others, it can look like avoidance — avoiding doctors, screening tests, exercise, or conversations about illness because they feel too overwhelming.
Common signs of health anxiety
- Persistent worry about having or developing a serious illness
- Frequently checking your body for signs of illness
- Repeatedly seeking reassurance from doctors, family, or friends
- Searching symptoms online and feeling more distressed afterwards
- Difficulty trusting medical reassurance or test results
- Avoiding activities or situations because of fear about health
- Finding that worries about health are interfering with work, relationships, or daily life
How CBT helps with health anxiety
Cognitive Behaviour Therapy (CBT) is one of the most evidence-based treatments for health anxiety. CBT is based on the idea that the way we think, feel, and behave all influence one another. In health anxiety, a bodily sensation or health-related thought can trigger a spiral of catastrophic thinking, anxiety, checking, reassurance-seeking, and avoidance. Although these behaviours are intended to create certainty and reduce fear, they often keep the anxiety going in the long term.
CBT helps people step out of this cycle. Rather than dismissing the worry, it encourages a curious, compassionate, and structured approach to understanding what is happening. Therapy often involves identifying triggers, noticing unhelpful thinking patterns, reducing safety behaviours such as checking and reassurance-seeking, and gradually rebuilding confidence in everyday life.
CBT strategies commonly used for health anxiety
- Psychoeducation: Learning how anxiety affects the body and how normal physical sensations can be misinterpreted.
- Identifying thought patterns: Noticing catastrophic thoughts such as “This headache means something serious” and learning to develop more balanced interpretations.
- Reducing reassurance-seeking: Gradually cutting back on asking others for reassurance or repeatedly booking medical appointments without new medical reasons.
- Reducing checking behaviours: Limiting behaviours such as scanning the body, checking for lumps, monitoring heart rate, or repeatedly researching symptoms online.
- Behavioural experiments: Testing predictions in a safe and realistic way to see whether feared outcomes actually happen.
- Facing avoided situations: Gradually returning to activities that have been reduced because of fear, such as exercise, travel, or social events.
- Tolerating uncertainty: Building the ability to live with some degree of uncertainty, rather than trying to achieve complete certainty about health.
What you can do now
If you notice yourself caught in a cycle of checking, Googling, or asking for reassurance, start by observing the pattern without judgement. Ask yourself: What triggered this worry? What am I predicting? What am I doing to feel safer right now? Is that helping in the long term, or only briefly? Small changes, such as delaying checking or reducing symptom searches, can begin to weaken the cycle.
It is also important to take genuine medical concerns seriously. CBT does not mean ignoring symptoms or avoiding appropriate medical advice. Instead, it helps people respond to health concerns in a more balanced way, without becoming trapped in repeated fear-based patterns.
When to seek support
If worries about your health are taking up a lot of mental space, affecting your sleep, relationships, work, or daily functioning, it may be helpful to speak with a psychologist. CBT can be tailored to health anxiety and can support you to better understand the cycle, reduce distress, and rebuild trust in your body and your ability to cope with uncertainty.
