Whats the truth about applying water to burns? Will cold water cause it to blister or stifle it? What about lukewarm water?

The reason you want to put cold water on a burn is because even after you remove the heat source that caused the burn, there is still thermal injury occurring until that heat can dissipate. Cold water helps dissipate the heat into the water rather than letting it continue into deeper layers of flesh. Lukewarm water can help, but the colder the water the better it is at carrying away excess heat. 

Water does *not* work for chemical burns, in which a suitable neutralizing agent should be used.

Frostbite is a type of burn caused by extreme cold, and is treated with slow rewarming of the areas affected. 

Blistering occurs when sufficient layers of skin are damaged by the burn, resulting in an inflammatory response leading to edema and fluid collection.
