I really feel the cold and last winter indoors I wore m&s thermals (extra warm, tops & bottoms under trousers), a long sleeve t-shirt, 2 fleeces & a hat. I used microwaveable hot 'water' bottles to warm my hands. I also bought an oodie- or kuddly-type thing from QVC (60 day money back guarantee) which was better than the 2nd top fleece as it also kept my legs warm. Throws are okay if you're stopping in one room & not moving much but when you leave the room you leave the warmth behind! Dunelm have them for £16/18 but I saw them online, no idea of the quality.
B&M had a half price airfryer this weekend (£25), I use mine all the time (the oven is used for storage).
I'm going to properly use my instant pot, currently just used for rice as I'm a bit scared of it ?. Apparently its great for pulses which are still cheap at the mo.
I have a heated airer for the washing but rarely put the heat on - I've found it actually only dries what it touches. If you are getting one (sorry, I've forgotten who!) I'd suggest getting the cover, presumably it keeps the heat in.
I only shower weekly, no need for more & top layers are washed once (or twice) in a blue moon. Quick wash, lowest possible temperature.
I use a water heater for drinks &/or boiled water, only heats what I use.
Think that's it. My plan for this winter is to stay in bed longer, tho that usually causes back pain ?
