Every night I have to throw a few blankets off of me in the early morning. I read somewhere (?) that the body cools during sleep. Somehow one of the implications was that taking a shower before sleep can help you sleep faster. The fact that a body is sweating indicates not necessarily that it is hotter than during the day; it could be that the body is trying to be cooler than it was during the day. (Of course, if you wake up feeling hot, it's probably because you're hot.) Thermodynamically, it makes sense that being in a bed, with insulation against almost all of one's body, would (once the insulation gets warm) leave someone warmer than when they're sitting or standing -- at least if the ambient temperature is the same in the day and night.
