Discovered a great way to cool my system down rather quickly. Didn't know if it might prove useful for you guys. Put an icepack over your carotid artery. (the big one on the side of your neck) For a couple of cycles of blood circulation. You have so much blood flowing through there that it cools the blood as it cycles, fairly fast, in turn cooling your whole body down. Hope that can be useful to a few folks. Helps me out when I get physical on the jobsite.
