Peggy, I am going through the same thing , my husband is always cold and he closes the windows up also, I went yesterday morning to get my hair done and it was about 72 out side I walked in the house and he had closed the windows and put the furnace on it was 72 in the house and he put the furnace on 76 he said he was freezing needless to say I fixed me lunch and got a glass of tea and went on the front porch and ate and then I cut the grass, washed the car pulled weeds stayed outside as long as I could. I to tell him to put warm clothes on or put his longjohns on(lol). I woke up this morning with the furnance running and I was wringing wet with sweat. So you are not alone. I just grin and bare it and go out side alot. I just hate to be closed up in the summer time. Good luck to you. Charolette
