Something to do with evaporation I believe? I was thinking maybe since alcohol boils much faster it bonds with the water and they therefore vaporize quicker am I right?

Thanks so much I didnt think about how its endothermic at all.

An alcohol Bath is normally used for dehydration of bacteria or living things .However, if a human being takes a bath in alcohol it may experience :
1.would not get drunk per se, the alcohol would dry the skin very fast and begin to burn. The fumes would/could make you dizzy and maybe even pass out from hypoxia
2. that is the mechanism of bacteria- killing by alcohol. Apparently, 70% works better than 100% alcohol, for some reason.
3."Absorption through the skin has been confirmed by a report (Dalt et al, 1991) of a case of a 1 – month old infant who became intoxicated as a result of absorption of ethyl alcohol from dressings applied to the stump of the umbilical cord and the skin adjacent to it.
Additional confirmation of skin absorption comes from a microdialysis study in which a long probe with was inserted under the skin for a distance of 3 cm. Ethyl alcohol was then placed in a small area on the skin above the probe while the subcutaneous area was being perfused. Analysis of the perfusate indicated the presence in an amount that was related to the extent of skin exposure (Anderson et al, 1991). "

Alcohol vaporizes quicker. But it is because it has weaker intermolecular forces than water, which has hydrogen bonding.
The fast evaporation of the alcohol cools the body and lowers a fever. Evaporation is a colling process because it is endothermic and absorbs heat from the body.

Sorry off topic but to clarify something that Mr McPe.. said.
Water and Ethanol will form an azeotrope. What this means is that as the alcohol evaporates it will contain about 5-14% water. You cannot obtain pure alcohol by distillation from a water alcohol mix. The best you can obtain is 95% Ethanol.

There's no way for alcohol to bond with water. It simply boils at a lower temperature and shouldn't affect the water at all if it does boil out.
However, I am unfamiliar with what an alcohol bath is.

it cools by evaporation,, OK
