My grandma complains all of the time about being cold. Even in 90+ weather. The heater we have on her bathroom can get so hot if feels like you are suffocating but she refuses to turn it off. Is this normal behavior? She has dementia and refuses to turn the heater off. Is this normal?
In the bathroom it's absolutely vital to keep it warm and draft free - you can always ventilate afterwards, once she's all snug and dry and wrapped up again.
Is she drinking plenty?
