After having spent 2 summers at McMurdo, Antarctica what you are speaking of is warm. A nice warm sunny summer day there was only down to 20F below. When I got home, well back in the States, I settled in the deep south. It doesnt snow here. After 50 years, I'm allergic to anything below. Wife is from Maine and came here for the same reason. We run the house from 65 to 70F. I wear long sleeves and have an electric blanket for anything below 70F. With wood floors, Wife's preference. I wish there was a reasonable way to heat the flooors in a 100 year old house.
I have read that having the floors heated, one can reduce the ambient far below 75F. Sounds plausable to me. All I have is rugs.
