+1 on the proper clothing & fixing the wood stove
My parents' woodstove is so ridiculously efficient that it was 83 degrees on Christmas Day! In the northern hemisphere! In the house! I nearly suffocated. They also have one of stove top fans like Linda mentioned. It helps move the air around the whole house, not just the room the stove is in. My parents have *forgotten* how to turn on the central heat, the woodstove is so good for what they need.
Last winter was the first winter in my life that I decided to embrace the philosophy of "there's no bad weather, only inappropriate clothing". I read here and other forums about the proper clothing, and visited outdoor gear stores to talk to the salesclerks. I'm not very outdoorsy, but I walk to work and wanted to be comfortable. Lot of layers in quality fabrics helped a ton! Breathable wool and 'performance fabrics'. Ebay and ThredUp, even the thrift store can have great deals if you know what brands and types you need. My DP has had great luck with estate sales and antique stores for heavy, durable winter clothing in classic styles. I bought a pair of ski pants to layer over my business clothes on Amazon for $25. I love the other poster's great idea about getting an 'ugly pattern' cheap online--that would probably work for lots of things!
To echo other posters, layers even in the house, and good houseshoes are imperative. My floor is the garage ceiling, so it's icy cold in the winter. I finally got a pair of wool house shoes and it helped so much. I also have fleece and sweater-type throws, even a Snuggie, around the sitting areas. Hot tea from the electric kettle that I steep in a Yeti tumbler to keep very hot. My roommate says he's never lived with someone who can stand it as cold as I can (around 64 degrees inside).
I also choose to do activities that will keep me warm. Sweeping the floor with a broom instead of the electric duster, saving laundry for when I'm home and can benefit from the heat from the dryer, cooking bubbling pots and filling the oven with baking goods.
Space heaters for the win! I have one in my cold cold tiled bathroom. You can also direct one at you in a larger room if you need to be sedentary.
Heated mattress pad. I turn mine on while I'm getting ready for bed, then turn it off when I lay down. I find a heating pad can be great to warm up the foot of the bed or tuck under your back for the same effect.
Do things that are unique to the cold climate. If it snows, go sledding or build a snowman. Drink hot chocolate or tea at the ice-skating park. Go to the local Winter Fest or similar celebrations. Do things that make you appreciate the cold time of year instead of dread it.
Have people over. Something about a group of people really warm up a space, even if you're just playing board games or talking. Maybe set your own winter tradition of weekly indoor activities!
Research 'hygge' and other cold-climate philosophies. I realized there are millions of people who seem to like, even LOVE cold weather, and I wanted to know why. I still don't LOVE it, but there are reasons to enjoy it, and that might help you get over the misery.
Definitely spend time outside, properly dressed, to 'harden off'. It does make the house feel warmer when you come back inside! My friend who used to live in Alaska makes a point every season to acclimate himself by spending lots of time outside, no matter the weather. He rarely complains about the outdoor temperature.
