Go buy a tin of Cinnamon Altiods mints and a tin of regular Peppermint Altoids. Take one of each candies and put them in your mouth where they are touching. It just tastes like sugar unless you leave them in one place too long.

I worked in HVAC for a while as a young man, and summers here get quite hot. We would put a few drops of menthol on the intake louvers every few days. People in the building always felt cooler.
