I moved from the 200 yr old farm cottage in July. My new lodging has 10 foot ceilings and I worry about how cold it will be inside this winter. I am trying to acclimate to 70 daytime as the weather cools. And will likely use my ceramic heater in the living room often this winter.
This summer I maintained daytime at 75 unless I was working hard doing something and working up a sweat. (That's not hard to do for me; I sweat and breathe hard just walking to the mailbox!!
)
Nights are currently at 67 with a bump up to 72 just before I get up and shower, then drops to 70.
I am, of necessity, mostly sedentary and that often makes my hands and ears, at least, stay cold in the winter.
