Yeah I agree 65-70 is a nice temp to sleep at. This summer I am having major temperature drama with my roommates (we share a 4 bdr apt) One of them is really thin and she is always cold. Mind you we are in SC and it is about 100 plus. This chic has a freaking space heater in her room running 24-7! She claims she is cold with the air on. So everyday we had a temperature war. I would turn the air on and they would turn the heat on. To make a long story short, I have horrible asthma and I was waking up with attacks because it was so warm and humid with the HEAT on at night and the 90 degree heat outside. I went to the on-campus doctor and she demanded that housing either "fix" the air at comfy temp or move me to my own private apt. Needless to say, I won and the temp is at 70 right now.
