Rinse in the Right Temperature
Taking a cold shower on a steamy day is practically a no-brainer. But for most people, a cold blast feels like too much of a shock, says Green—so they can't bring themselves to take the plunge. Good news: The water doesn't have to be ice-cold. In fact, when you get out of an arctic shower, your body may actually generate an excess of heat in order to make up for the sudden loss. Green suggests tepid water, which is more comfortable and just as effective at helping you cool off.
