It’s hot out there. How about a nice cold drink?
You hear the clink of ice cubes in a tall glass, see the beads of sweat condensing on the outside, and you just know you’re in for some serious refreshment.
So why does the rest of the world drink hot tea in hot weather?
Can a couple of billion subcontinental residents be wrong?
A hot drink tells the nerve receptors in your mouth that things are getting hot in there and it turns on a cooling response. Basically it makes you sweat, which transfers body heat into the atmosphere as the perspiration evaporates. It works with spicy foods too—the receptors in your tongue read hot peppers in the same way as they read hot tea. Either one triggers a message to the brain telling it to cool things off.
If you’re not much of a sweater, you might want to stick with cold beverages.
You need to produce a fair amount of perspiration; otherwise, a hot drink will just make you feel flushed and even hotter. It needs to really get you sweating so that the cooling effect of perspiration will exceed the heating effect of the beverage.
Hot or iced- which should you choose?
Personally, I still would like a nice iced coffee, but feel free to give a hot one a try.
