You wouldn't know that fall is coming from the last two days, with temperatures expected to perhaps reach the 90s in New York and across the Eastern seaboard. And that presents perhaps one of the last opportunities of the summer to drink extremely hot things in extremely hot weather.
Inevitably, the barista asked if I wanted my coffee hot. Maybe I am paranoid, but she looked at me curiously when I said that I did want it hot, which is the way I always want it. I don't blame her, though, because most everyone around me is drinking iced coffee, clutching their flimsy plastic cups. It is the same outside, where people move lazily through the morning's heat and haze.
Pity these people, these iced-coffee drinkers. Theirs is a paltry defense against the heat, exacerbated by the fact that caffeine is a diuretic (albeit a mild one) that will dehydrate the body regardless of which form it comes in. So while the ice cubes in an iced coffee may indeed have some cooling quality, their effect is likely minimized by the very caffeine solution they are supposed to cool. Moreover, they turn coffee into watery swill — one that we are forced to drink through a straw, as if we were still children.
It's not just culture that drives people to fight heat with heat. Researcher Ollie Jay explained the phenomenon to Smithsonian magazine:
“Yes, the hot drink is hotter than your body temperature, so you are adding heat to the body, but the amount that you increase your sweating by—if that can all evaporate—more than compensates for the the added heat to the body from the fluid.”
That settles it, doesn't it? But I fear that the sweat is drying. Time for another coffee — a hot one, that is.
