The latte, the martini, the cigarette you bummed from a friend—on a hot night, these indulgences will make you feel even sweatier. Alcohol dilates blood vessels, raising overall body temperature and increasing sweating, while caffeine stimulates the central nervous system and activates the sweat glands (as can nicotine, to a lesser effect). To be more comfortable in creeping temperatures, especially if you plan on tearing up the dance floor, consider ordering a decaf iced coffee,
a refreshing ice tea spritzer, or a single, sippable martini with extra rocks.
One more thing: Smoking can also affect the odor of your sweat.
