When I first came to live in Malta, almost 40 years ago, there was no air-conditioning anywhere so we all sweltered in the heat and humidity.
Our first two DDs used to be wet with sweat after a car journey, even with windows open. We were so excited when we bought our first car with a/c and it certainly made a huge difference when DD3 and DS were babies.
Having said that, now I’m on my own, I don’t much like the a/c. As Maw says, it affects my sinuses, so I only use it in the car when desperate!
In the house, I rarely use it, but my daughter in the US has the house so cold I call it the ‘meat locker’, ditto the shops and restaurants over there where you really need a cardi.?
