Laurel’s mention of the “colpo d’aria” reminds me of my relatives.
In Tuscany we call the “colpo d’aria” a “FRESCATA” (literally a strike of fresh air).
It can be caused by anything: going from a hot environment to an air conditioned one, or a sudden draft caused by a fan or open window., opening the refrigerator without a shirt on.
The “frescata” can cause all kind of ailments: cold, influenza, pneumonia, arthritis (colpo di strega), congestion, and if prolonged, even death.
If you show up sick with a cold, the first thing you hear is “Hai preso una frescata!” (You got a strike of fresh air)
The fear of a “frescata” is the reason why many Italians set air conditioning to kick in at 77-80 F (25-27C). My father used to start arguments with me when I turned on the fan in Florence 100 F weather. He never installed air conditioning in our house, not because of lack of money, but because of the ill effects the FRESCATE would bring to our health (Yes, I grew up in Florence without air conditioning because of my parents’ stupid “frescata” myth)
