Your metabolic rate can be several times higher in a pool or other body of water than it is on land without any exercise at all. Body heat is lost at a much higher rate when you are submerged in water and your body will burn more fuel to maintain core temperature.

I just think the American pronunciation (SAW-dur) sounds wrong.
