Fear of Fresh Air and Drafts

What the word originally meant

The Online Etymology Dictionary dates aerophobia to 1785 and glosses it as a morbid dread of a current of air, built from aero- and the suffix that had itself only entered English the year after, in 1786. The psychological sense of that suffix, an abnormal or irrational fear, is not attested until 1895, so the first century of the word's life describes a physical intolerance rather than a phobia in the modern meaning.

Its early company is worth noting. Etymonline quotes a source observing that the older writers used aerophobia, a dread of air, alongside pantophobia, a fear of all things, and treated both as appropriate labels. Those two sit at opposite ends of specificity and were in the same vocabulary.

Rabies is where the old sense is still used

The English Wikipedia notes in passing, in its article on the fear of flying, that aerophobia also means a fear of draughts or of fresh air, especially in rabies patients. That is the whole of the modern clinical usage as the sources here record it. No figure, no case description and no mechanism accompanies the sentence, and the entry does not extend it. What can be said is that the older meaning is not extinct, that the setting in which it survives is a specific disease, and that a reader who arrives at the word from an airport departure gate would not recognise it there.

Why the definition still carries miasma

Ronald Doctor, Ada Kahn and Christine Adamec define aerophobia in the third edition of their encyclopedia, published in 2008, as a fear of air, draughts, gases, or airborne noxious influences, and give air phobia as an alternative name. The phrase airborne noxious influences is not a modern description of anything. It is the miasma theory of disease, the idea that illness travels as a corruption in the air, preserved in a definition that a reference work was still printing after the germ theory had been settled for a hundred and thirty years.

The same entry adds the sentence that explains the confusion. This term is sometimes used as a label for the fear of flying.

What the dictionaries record now

Merriam-Webster's entry for aerophobia gives one definition, fear or strong dislike of flying, and cross-references it to aviophobia. The draught sense is not listed as archaic or as secondary. It is absent. Every usage example the dictionary prints is about air travel.

The Cleveland Clinic's page, last reviewed in 2022, does the same. It treats aerophobia as an extreme fear of flying, puts the number affected at more than 25 million adults in the United States, and reports the fear as most common between the ages of 17 and 34, a period it associates with graduation, marriage and childbirth. None of that has any bearing on a fear of draughts, and it is what a person searching the word now finds.

Why the newer sense won

A fear of what the air contains and a fear of being held up by it share nothing:

• no common object
• no common trigger
• no common treatment The word covers both because its literal reading, fear of air, is broad enough to be attached to anything that happens in air. That looseness is also why the newer sense won: aviation gave the word a large population and a clinic to be treated in, and a dread of draughts gave it neither.
