Fever Naps?

OK, so here’s a dumb question which I should probably already know the answer to…

I went down for a lovely Saturday afternoon nap on the couch, and woke up an hour or so later drenched in sweat and feeling almost feverish. Which seems to happen 100% of the time with daytime sleep. It’s not that warm in the apartment, and it seems to happen to other folks – what is it that’s happening during that short sleep that makes it feel like I was napping next to the oven, and not in a perfectly comfortable room on a perfectly comfortable couch?

Just wondering…
