I used to have a co-worker who, on the hottest of summer days, would drink a pint of hot water through a straw and claim it helped cool her down. Naturally, everyone thought she was insane or belonged to some weird religion, or both, and would try to avoid working a shift alone with her.
But it looks like her weird sect of Scientology or whatever it was may have been onto something, as our Japanese reporter swears by eating microwaved steam buns to cool off in the summer.
