Medical treatment based on exposure to air, particularly fresh air or specific atmospheric conditions.
From Greek aero- (air) and therapy (healing, from therapeia). A historical medical term popular in the 19th and early 20th centuries.
Aerotherapy was one of history's most accidentally correct medical treatments—doctors thought it was the 'purity' of mountain air healing TB patients, but really the combination of rest, sunshine, and oxygen made all the difference.
