No, I am absolutely not endorsing any type of military intervention or exercise. Rather, as Lloyd Alter and Collin Dunn explain, a Navy shower is "the term used for a water-saving technique that was started in the Navy to help save precious freshwater aboard ships. The basic idea is to hop in the shower, get wet all over, turn off the water while soaping up, and then rinse clean. The small change in routine makes a huge difference: a regular shower can use as much as 60 gallons of water, while a Navy shower can check in at about 3 gallons."

"If you love taking a relaxing hot shower in the morning, you will hate the Navy shower," they tell us at LifeHacker.com. "However, if you're constantly busting your hump to make it to the office on time, the Navy shower might be just what the doctor ordered. Besides saving money and getting you to the office on time, you can help save the environment every morning."

Remember: 21% of household water use comes from the shower.
