I work in a hospital where your not able to open windows more than a sliver in case patients throw themselves out of them, the air is always humid even when it's dry outside and air conditioning is a sin and only allowed in a tiny minority of areas. Since the window in my area has to remain shut over night, and you get to open it about the width of my hand in the morning, the blast of sticky air that hits you when you walk into the room is horrible, and it doesn't get any cooler. There is a large amount of equipment on charge where I work which raises the temperature of the room by about 2 degrees above normal, luckily we seldom spend much time in this area as we are running about trying to deliver equipment to people all day, well I say running it's more like a sort of go slow at the moment for obvious reasons. I come home and the back of my tea shirt from shoulder to shoulder is covered in white salt crystals where my tea shirt has become super saturated. Still my boss is off for the week, so no whip if I deign to sit down for a few minutes, thank God for small mercies.
Apparently there's a desert salt mine in east Africa which is mined by hand by a handfull of lunatics, where the temperatures can reach 50 degrees C during the day, so it could be worse. In fact it's positively chilly by comparison, I just gave myself goose bumps
