Clothing. I got out of the habit of bothering with heaters because my old house couldn't be efficiently heated (it had tonnes of windows and was open plan), and this place is smaller and has insulation so we don't need it as much.
I will always add extra clothes, as to be really honest,I do not even own a heater ,with living in the tropics! I cannot remember what having a heater is even like anymore,as I have been here for 35 years now!!!
Not a lover of the cold....I will do anything to stay warm.
So whatever is at hand first, then the other. We have had our aircon on all night....and I just must stay warm, but we do live in a mobile home, so not much insulation.Plus it is small, so we only have to heat up a small area...For me, plenty of clothes and aircon.
Can't put on more clothes' than I already wear!
But that's enough, usually, to keep me warm!
Any colder, & I'll put a doona over me, & watch VHS tapes or DVD's. Have always Newspapers' to catch up on! Or books!
Haven't got a heater, doubt I'd buy one anyway, as get nauseous easily from heat generated like that!
Heater for me as I need the background environment to be a bit warm, though I do wear about 3-4 layers too, including a couple of jackets. But then I have a condition where I'm ultra sensitive to the cold.
I am a put on more layers of clothing kind of girl. The way I can tell it is time for the heater on is by feeling my dogs ears. If they are cold, and she has given up sitting on top of her cushion and is trying to bury herself in the cushion than I know it is time. Being a writer I do tend to get involved in what I am doing and become unaware of such things as hunger, thirst and temperature. Thank god for my wee dog otherwise it could all come crashing down!
