actually sweating is necessary to get bacteria out of our bodies, but you do have to drink a lot of liquids. doesn't have to be cold just wet. try to stay away from sodas. most colas have caffeine in them and it is hard on your kidneys. paul g has good answers. also you could try corn starch, for overall sweating. some powders have anti bacterial agents in them. they are good also. if you get overheated sit down and relax. keep your head covered if you are working in the sun to prevent heat stroke.
