Very, very very small amounts. As in, you can sweat that amount away in a second. Because the lungs are made to exchange CO2 and O2 to/form air to/from the bloodstream. Not water molecules. Limited exchange will happen, but not enough to be consequential.dbungus2000 said:If its really humid and you breath it all in, are you hydrating yourself?
not really it would most likely go into the mucus that laces your lungsD Bones said:Ooooh, I didn't think about sweating....But still water going into your lungs would diffuse throughout your body....I think.wasalp said:nope all it does is make you dehydrate slower...somewhat. The problem is that high humidity mixed with high heat will make you sweat more thus overcoming the reduction of the rate of dehydration...so...you lose more water
