Dude, calm down. I never said that the hypothalamus wasn't the control center for temp regulation, merely that it uses data from the skin to decide what to do. the skin provides real time information about the significant changes to the environment, and, in fact, increases and decreases the sensitivity of the central sensors in the hypothalamus. Think about it, it would be pretty stupid to have to wait until your core temp was falling to begin heat conserving measures.

stepping into a cold shower can trigger this even before you've actually cooled off from your workout, so unless you're planning on hanging out in the shower for awhile, you're probably better off with cool water that won't cause reduced blood flow to the surface.
