I've been playing around with sleeping with a fan & air-conditioning and I always notice that my throat is all dryed out in the morning from the air flow directly over my face.

A lot of research seems to suggest that cold (something like 62F-68F) is indeed better for sleep. It makes sense if you think about it "evolutionarily" or whatever. Basically, your body feels warmth and it assumes the sun is what's heating you up, so suppresses sleep hormones and promotes wakefulness. Anecdotally seems true for me, but I also have poor circulation to my extremities so I just suffer one way or the oth…
