Fear of Water
Aquaphobia
The word for fear of water is a Latin word because the Greek one was already in use for something else. Hydrophobia, built correctly from hudor and phobos, had long been used across several languages to name a symptom of late-stage rabies: difficulty swallowing, distress at the sight of liquid, and a thirst that cannot be relieved. The fear itself therefore took aqua and became aquaphobia, and the naming accident is the most interesting fact about the term.
What it attaches to
The range is wider than swimming pools. The 2015 reference Phobias: The Psychology of Irrational Fear describes fear provoked by being near a creek or a fountain, by putting a head under the surface, by opaque water where nothing can be seen, and by travelling on a boat. In rarer cases a bath does it. English Wikipedia adds drinking water and washing dishes to the list.
The core of the fear, in the 2015 account, is harm rather than water, and it shows up most often as a fear of drowning. That holds even among people who swim competently. Where the fear is confined to deep water, the reported content changes: what is feared is what might be underneath.
Why the figures disagree
This is one of the few entries in the catalogue with real numbers, and having several is worse than having one.
Stinson and colleagues put the general-population prevalence at 2.4 per cent in 2007. A study drawing on epidemiological data from twenty-two countries across all income bands measured fear of still water or weather events at 2.3 per cent overall and 4.3 per cent in the United States, though that category folds two different fears into one figure. Lindal and Stefansson estimated that aquaphobia may affect 1.8 per cent of the Icelandic population, close to one person in fifty.
Alongside those sits a different kind of number entirely. Forty-six per cent of American adults are reported as afraid of deep water in a pool and sixty-four per cent as afraid of deep open water. Those are not phobia rates. They are the ordinary distribution of caution, and the gap between them is the distance between a normal reaction and a diagnosis.
What aquaphobia costs
The 2015 reference lists the things that get declined:
- poolside gatherings
- attractions with ponds or fountains
- holidays at a lake or a beach
- fishing and boating Some people never learn to swim because they never go near water. Others try and cannot, because floating requires a relaxation the fear will not permit, which is a mechanism rather than a metaphor.
Being splashed or pushed in as a joke can produce a panic attack.
What the treatment record holds
The treatment record is thin and specific. A twenty-eight-year-old woman, aquaphobic since childhood, was treated with hypnosis and systematic desensitisation across five sessions in eight weeks, with follow-up at two months and a year. A thirty-seven-year-old man who had been unable even to drink water for ten years was treated in six sessions of hypnotherapy without relapse at six months. His fear had first presented as pain and tightness across the forehead, a choking sensation, discrete panic attacks and a falling fluid intake.
A programme called SOAP, for Strategies for Overcoming Aquatic Phobias, teaches swimming skills alongside the psychological work, which is the rare intervention that addresses the practical consequence as well as the fear.
Where the causes were looked for
Poulton, Menzies, Craske, Langley and Silva examined in 1999 whether water fear is learned or inherited, and the position that survives is that both non-associative factors, such as biological preparedness, and associative ones, such as a frightening incident, contribute. Onset is typically in childhood and the fear is more common in children than adults, which fits a fear that many people grow out of and some do not.
Told apart
Often confused with Fear of Water
- Fear of the SeaThalassophobia takes deep bodies of water as its object and aquaphobia takes water itself, which means a bath and a glass of water fall inside one term and outside the other. The source articles state the distinction and it is ignored almost everywhere else.
- Fear of DrowningDrowning is the reported content of most water fear rather than a separate fear, and the 2015 reference notes it persists in competent swimmers, where the risk it names has largely gone.
Common questions
Questions about Aquaphobia
- Why is it not called hydrophobia?
- Because that word was already spoken for. Hydrophobia is the correct Greek construction, and it had been used for centuries across several languages to name a symptom of late-stage rabies: an inability to swallow, fear at the sight of liquid, and unquenchable thirst. The fear of water was left to build itself from the Latin aqua instead.
- Do 64% of American adults have this phobia?
- No. Sixty-four per cent of American adults are reported as afraid of deep open water and forty-six per cent of deep water in a pool, and those figures describe ordinary caution. The phobia rates from named studies sit between 1.8 and 2.4 per cent. Confusing the two is how a common reaction gets published as an epidemic.
- Does it go away if a person learns to swim?
- Not reliably, and the 2015 reference is explicit that the fear of drowning persists in people with adequate swimming skills. The relationship also runs the other way: some people never learn because they avoid water entirely, and others cannot learn because floating requires a degree of physical relaxation the fear prevents.
- What is SOAP?
- Strategies for Overcoming Aquatic Phobias, a programme that teaches aquatic skills alongside cognitive and emotional work. It is unusual in addressing the practical consequence of the fear, an adult who cannot swim, at the same time as the fear itself.
- Can the fear extend to drinking water?
- In severe cases it does. One documented patient, a thirty-seven-year-old man with a ten-year history, could not drink water at all, and his fear had begun with pain and tightness across the forehead, a choking sensation and a falling fluid intake.
