I like 74 degrees with light cover, just a sheet, or no cover, and, my ceiling vent blows directly toward my bed. During the day we bump it up a couple of degrees to save a bit of money. I dress very light on hot days (>82F). At home, it's usually just some shorts and no shirt and some flip-flops. I add a straw hat and sun glasses when I go outside and stay in the shade as much as possible.

I know Imuran and pyridostigmine temperature requirements have a high of 77. I doubt 78 makes a difference. That is why we have the air conditioning on right now. Like you, 74 air conditioning degrees seems awfully chilly for the summer. b.

We keep the air at 74 at night which my husband finds cool but is willing to do.
My perfect temp is 68, day or night, but I'm afraid I'd be a single woman.

My thermostat is broken. One day I can be comfortable at 80 and another time I can be way too hot. I have also had a problem with hypothermia at normal ambient temperatures. It is an autonomic function problem and my answer to it is layers. I can take them off or add them in.

I notice when I lay down at night I feel warmer for the first five minutes then I need another cover...then another and another. I have learned to have them folded back so I can gradually pull them over. OF course they can need to come off again just as quickly.

I also like to sleep with a fan if I feel warm and there is no outside breeze.

Had to smile at Lissim's comment on husband and temperature. It is disconcerting to my husband who has seen me perfectly comfortable at 80 degrees.....As well as putting on leg warmers and a knit hat at 80 degrees because my body temperature was too low....and also drinking cold icey drinks at 80 degrees and turning on the AC because I felt too hot.

For sure if I get overheated my muscles get much weaker. I absolutely cannot get into a hot tub or I turn into a jelly fish.
