Rudyard Kipling, in several of his short-stories makes reference to hot tea as an aid in heat. For example, in "At the End of the Passage" the characters are suffering through 101 degree, unrelenting even at night humid Indian heat.

" - thank Heaven who has set a term to our miseries,' said Spurstow, settling the cushions under the head. ' It occurs to me that unless I drink something I shall go out before my time. I've stopped sweating, and - I wear a seventeen-inch collar.' He brewed himself scalding hot tea, which is an excellent remedy against heat-apoplexy if you take three or four cups of it in time."
