Phobias: when a fear takes over

A phobia is a fear that is far stronger than the real danger, strong enough to shape where you go and what you do.

What a phobia is

A phobia is an intense, lasting fear of a specific object or situation. Even thinking about it can bring on anxiety. People usually know the fear is out of proportion but feel unable to control it.

Common phobias

  • Flying, which is hard when your family lives on another continent
  • Needles, injections or blood, which can delay medical care
  • Driving or motorways
  • Heights, lifts or enclosed spaces
  • Dogs and other animals
  • Vomiting
  • Deep water

Agoraphobia is a wider fear of places where escape feels hard, such as crowds, public transport or being far from home.

How phobias affect life

Missing a sibling's wedding abroad because you cannot fly. Avoiding blood tests during pregnancy. Turning down a job because it involves the motorway. Phobias can shrink life quietly.

How phobias develop

Some phobias follow a frightening experience. Others are learned by watching a parent's fear. Some appear without any clear cause. Avoidance then keeps them alive, because you never get the chance to learn the situation is safe.

How therapy helps

Graded exposure is the most effective treatment for specific phobias. With your therapist, you build a ladder of steps from least to most frightening and climb it gradually, staying in each step until the anxiety falls. For a fear of flying, that might start with looking at photos of planes and end with a short flight.

Exposure is done at your pace, with your agreement, and many specific phobias respond in a small number of sessions.

Needle and blood phobia

People who faint at the sight of blood or needles have a different body response: blood pressure drops. Therapists teach "applied tension", tensing muscles to keep blood pressure up, alongside gradual exposure.

Questions people ask

What is a phobia?

A phobia is an intense, persistent fear of a specific thing or situation that is out of proportion to the real danger and leads to avoidance.

What is the treatment for phobias?

Graded exposure therapy, usually as part of CBT, is the most effective treatment. You face the fear step by step at your own pace.

Can a fear of flying be treated?

Yes. Exposure-based therapy helps many people fly again, often combined with information about how planes work and ways to manage anxiety on board.

How many sessions does it take to treat a phobia?

Specific phobias often improve in fewer sessions than other anxiety problems, sometimes only a handful, depending on the person and the fear.

Can online therapy treat phobias?

Yes. Much of the work is planning and reviewing exposure steps you practise in real life between sessions.

I faint at the sight of blood. Is that a phobia?

Fainting with blood or needles is common in blood-injection phobia. A technique called applied tension can prevent it.

What is agoraphobia?

Agoraphobia is fear of situations where escape might be hard or help unavailable, such as crowds, transport or being away from home. It often follows panic attacks.

Will exposure therapy make me panic?

You will feel some anxiety, but steps are agreed with you and go at a pace you can manage. Anxiety naturally falls when you stay with it.

Can children have phobias?

Yes, fears of the dark, dogs or vomiting are common in children. Most are outgrown, but persistent phobias respond well to treatment.

Should I just force myself to face my fear?

Sudden, overwhelming exposure can backfire. Gradual, planned steps, ideally with a therapist, work better.
