How to take shorter showers?

skip washing your whole body with the pouf every day (save it for once or twice a week, or after using a pool or going to the beach). just wash the areas that sweat, with your hands. Consider shaving every other day, especially during the colder months, when people aren't observing your armpits. if you can stand it, skip rinsing your body and hair before just rinsing everywhere with cold water. That is to say, rinse your body and hair with cold water.
