I want the reverse of this. I live in the South in the states, so the summers are miserable, and my roommates like it warm (like 75+), but I want to sleep cold and I just sleep so much better that way. I wish there was a way to get the opposite effect efficiently somehow. Sadly, fans just don't do it for me as the noise bothers me; I don't like much white noise when I'm sleeping.
