What Is Acrophobia? Fear of Heights, Symptoms and Treatment

Acrophobia is an intense, lasting fear of heights that goes far beyond normal caution. It can make everyday situations — climbing stairs, crossing a bridge, standing near a balcony — feel frightening or impossible. It is one of the most common phobias, often starts in childhood, and can be treated with talking therapies such as exposure therapy and CBT.

What is acrophobia?

Acrophobia is the name for an extreme fear of heights. The word comes from the Greek akron, meaning summit or peak, and phobos, meaning fear. It is classed as a specific phobia, a type of anxiety disorder in which fear centres on one particular object or situation. The Cleveland Clinic describes it as a mental health condition in which a person experiences intense fear and anxiety when they think about tall heights or are positioned at a significant height, and often avoids situations or places that involve heights.

Feeling a little uneasy at the top of a tall building is normal — most people are more cautious than usual at a significant height. Acrophobia is different: the fear is intense, unreasonable for the actual risk, and it interferes with daily life. The Mayo Clinic notes that with a specific phobia you may know your fears are not reasonable, yet still be unable to control them, and that anxiety gets worse as the feared situation gets closer in time or distance.

Heights that commonly trigger acrophobia include walking up a flight of stairs, being on a ladder, using a multi-storey car park, crossing a bridge, standing near a balcony or at the top of a building, and looking out of a window in a tall building. Simply thinking or talking about heights can be enough to trigger anxiety.

How common is acrophobia?

Acrophobia is one of the most common phobias. The Cleveland Clinic estimates that approximately 3% to 6% of people have acrophobia. In the UK, a 2014 YouGov poll found that 23% of those surveyed said they were “very afraid” of heights, making it Britain’s most commonly reported phobia, according to Climb Above Fear. Restless lists it among the 10 most common phobias in the UK.

Specific phobias can affect anyone at any age, but they are more likely to develop in children and become apparent in adolescents and young adults. Females are more likely to develop specific phobias than males, according to the Cleveland Clinic. Acrophobia also commonly occurs alongside other mental health conditions, such as anxiety and depression.

Symptoms of acrophobia

When a person with acrophobia faces heights — or even anticipates them — the brain treats the situation as a threat and switches on the fight-or-flight response. Symptoms fall into three groups.

Physical symptoms

• A racing or pounding heartbeat, chest tightness and shortness of breath
• Trembling or shaking, sweating and feeling sick
• Dizziness or light-headedness, and feeling as if you might faint
• Dry mouth, an upset stomach or diarrhoea

The NHS lists the same pattern for phobias generally: severe anxiety and worry, dizziness, palpitations, tightness in the chest, feeling sick, trembling, and a strong fear that you may faint, lose control or die.

Emotional symptoms

• Intense fear, distress or panic when high up, or when thinking about heights
• Constant worry about encountering heights in the future
• An extreme fear of being trapped somewhere high
• Feeling confused or angry at your own reaction

Behavioural symptoms

• Avoiding situations that could involve heights — even if it makes everyday life difficult
• Turning down a high-floor hotel room, avoiding visiting people who live in flats, or refusing to travel
• Freezing in place when faced with a height, or needing to sit or lie down
• Planning routes and holidays around avoiding bridges, tall buildings and stairs

Avoidance brings quick relief, but it keeps the fear going: you never learn that the feared outcome rarely happens, so the fear grows stronger over time.

Acrophobia vs vertigo: what is the difference?

Acrophobia is often confused with vertigo, but they are different. Acrophobia is a type of anxiety disorder — an intense fear of heights. Vertigo is the feeling that you, or your environment, are suddenly moving or spinning, and it can be a symptom of a range of conditions, including inner-ear problems. The two can sometimes go hand in hand: vertigo at height can make the fear worse, and anxiety can make dizziness feel stronger. If you feel that the room is spinning, that is vertigo rather than acrophobia, and it needs its own medical check.

What causes acrophobia?

There is no single cause, and it is not always clear why a phobia starts. The NHS notes that many phobias can be linked to a frightening event or stressful situation, and that they usually develop as a child, teenager or young adult. Factors that can play a part include:

• A frightening experience. A fall from a height, or being stuck somewhere high as a child, can leave a lasting link between heights and danger.
• Learning from others. Growing up with a parent or family member who feared heights can teach the same response.
• Family history of anxiety. Anxiety disorders can run in families, and some people are naturally more anxious than average.
• An irrational fear of falling. Research suggests that an irrational fear of falling plays a significant role in how people perceive height and can aggravate acrophobia, according to Restless.
• Embarrassment about the reaction. The NHS notes that other people reacting negatively to your panic or fear can increase anxiety around the phobia.

How is acrophobia diagnosed?

Many people do not need a formal diagnosis to know they have a fear of heights — it is fairly clear if heights cause a lot of distress. But a GP can assess it properly, and a diagnosis matters if you want treatment through the NHS. Health professionals usually diagnose a fear as a phobia if the symptoms have been present for at least six months, cause significant distress, and interfere with daily life, according to Climb Above Fear. A clinician may use the criteria in the DSM-5, the Diagnostic and Statistical Manual of Mental Disorders, and questionnaires such as the Acrophobia Questionnaire to assess how severe the fear is. A formal diagnosis is not required to access private therapy, which a therapist can offer after a simple consultation.

Treatment for acrophobia

There is no outright cure for acrophobia, but most symptoms can be successfully managed through therapy, and success rates for phobia treatment are high. The main treatments are talking therapies.

Exposure therapy

Exposure therapy is often considered the most effective treatment for acrophobia. It involves being gradually exposed to heights, starting with the least frightening situations and working up, while learning tools to cope with the fear. Treatment might start with looking at pictures of tall buildings or watching videos of them, then move on to walking up stairs or crossing a bridge. Over time, repeated exposure without any terrible consequences helps you become desensitised to heights. It can be carried out in person, online, or using virtual reality (VR) technology, which lets you experience heights in a safe, controlled environment.

Cognitive behavioural therapy (CBT)

CBT is one of the most common forms of therapy for phobias. It helps you recognise patterns of negative thought — for example, “I am going to fall” — and reframe them into something more rational, such as “This structure is safe, and I am in control.” CBT also teaches coping strategies and helps you get to the root of the anxiety. It can be delivered in person, by phone, or by online video. In England, you can self-refer to NHS talking therapies, or ask your GP to refer you.

Hypnotherapy

Hypnotherapy guides you into a relaxed, trance-like state where the subconscious is more accessible, and can be a good option when the origin of the fear is unclear. It can take place in person, online, or through pre-recorded guided sessions.

Medication

Medicines are not a cure, but they can help manage symptoms. The NHS lists antidepressants, beta blockers and sedatives as medicines sometimes used for phobias. Beta blockers can ease physical symptoms such as a fast heartbeat or trembling, while antidepressants can reduce the anxiety itself. Tranquillisers are only used for severe anxiety, for the shortest possible time, because they can be addictive. Talk to your GP before taking any medicine for a phobia, and do not take anything that has not been prescribed to you.

Coping strategies and self-help tips

Self-help can reduce the fear, especially when it is mild to moderate. The NHS and Restless suggest these steps:

• Practise breathing exercises. Slow, deep breathing helps calm the nervous system when anxiety rises. Relaxation techniques such as mindfulness, grounding and visualisation also help, and they work better with regular practice.
• Talk about it. Being open with loved ones about your fear can help them support you and can reduce your anxiety.
• Learn your triggers. Notice which situations, memories, sights or smells set off the fear, so you can prepare coping strategies in advance.
• Challenge the fear. Phobias are by definition irrational, so consider the genuine safety of the situation — skyscrapers, for example, are engineered to be extremely secure.
• Face heights gradually. Start small — for example, standing on a low step — and build up slowly, rather than forcing yourself into the most frightening situation at once.
• Join a support group. Meeting others with similar fears, online or in person, can help; mental health charity Mind can help you find a local group.
• Look after sleep and caffeine. The NHS advises against energy drinks or drinks containing caffeine after 3pm, as they can affect sleep and make anxiety worse.

When to see a doctor

See a GP if you think you have a phobia and the symptoms are affecting your life — for example, if you avoid work, travel, social occasions or everyday tasks because of heights, or if the fear has lasted six months or more. A GP can assess your symptoms and refer you for talking therapies; in England, you can also self-refer to NHS talking therapies without seeing a GP first. Get help sooner if the fear comes with panic attacks, low mood, poor sleep, or if you are using alcohol to cope.
