My mother has become very intolerable to temperature. at night she is always cold and I am forced to keep the temperature at 83° .She is still cold so she wears her robe to bed while having enough blankets on her too. She wakes up in the middle the night and her clothes are soaked with sweat and then she gets cold again. We change her clothes out and put her in dry ones and she goes to bed and it all happens again. I have also tried to ceiling fan in reverse direction and she still claims it makes her cold. In the past we have been able to keep it at 80° and that has worked fine up until this season. Does anybody have any ideas or better yet solutions that can help me with this issue. Like Phoenix hasn't been hot enough already that she has actually expected me to be running the heater.
