Alcohol evaporating will transport water with it. Water that your body has already sweated is basically lost from your body. I'm not an MD. My question involves water not yet sweated. Will alcohol in contact with the skin accelerate dehydration by pulling out water not yet released through sweat?
who the hell cares? this isn’t something you do to prevent heat stroke. It’s an emergency measure to quickly get your body temp down after you are already incurring damage. If an elderly person collapses in the noonday sun and there’s no ice and no AC, what are you going to do? splash some alcohol on their skin and save their life? or worry about the drying effects on their skin?
