There are two kinds of sweat defined in numerous texts on physiology; sensible and insensible. The sensible is the kind you feel on your skin like when you get too hot. The insensible sweat is the kind that constantly comes off you even though you don't know (sense) it. Sorry if you already know all this, I wasn't sure from your message. And I agree with you. If you stop the evaporation that stops heat loss. (that is just physics: to evaporate 1 g of liquid water, approximately 600 cal are required.It is called latent heat because it reappears when the change of state is reversed.)
