Quick thing on this one, as Recon is right, but it also takes more energy to use the cold water. To use this method properly you have to pee quite often. because first the body has to heat up the water to even use it, but then it may take a very long time to sweat it out. But if you drink a lot of water, and make yourself pee, you release heat much faster. I do understand that peeing in a ghillie suit can prove to be difficult, but it's a great way to get rid of heat.Recon337 said:1) Drink cold water. Colder is better because it absorbs more heat and replaces what you lost from sweat.
