My MIL is always cold. She's losing words but not the word COLD. I heat my house to 72 but that is freezing to her. She is bedbound and covered with minimum of 4 blankets at all times. Also, one of them is electric blanket. If she is unsettled for any reason it still comes out as.............."It's cold in here."
Honestly, it is very expensive to heat my house to 90............just to keep her head and shoulders warmer. (She's covered with blankets everywhere else) but nothing is good enough and the implication to visitors is that I am freezing her out. Her bed is in my living room (very high ceiling) so the warm air goes right up there.
A friend of mine said to try a scarf around her neck which would give the warm, cozy feeling so I just tried that.
