Dress appropriately, that's all. I had a merino t-shirt, zip-up sweater, Fjällraven winter jacket (memey but warm and worth it, IDC), a scarf and merino toque. Merino or normal underwear, merino long-johns, thick merino socks, my jeans or gym pants, and cross-country skiing pants. Meindl winter boots. Even standing around at night for pic related at -30°C was OK. (No wind, still air, all the humidity frozen out of the air, you don't feel the cold that much -- until maybe it's too late). If we were active, I often had to take my gloves off and open my jackets and I'd be steaming.
The worst was setting up my camera tripod for long-exposure shots. I had to take my gloves off to handle the tripod or camera buttons, and metal exposed to -34°C (coldest it got) gets pretty damn cold very quick (it's also shit for your batteries). Touching the metal with bare hands would give you a cold "burn" almost right away that hurt to touch, like touching hot metal but backwards.
The place we (wife and I) stayed had a sauna, and jumping naked out of 90°C sweat box into -20/30°C is exhilarating. You feel relaxed and yet like you ran a 10k jog at the same time. Jumping into cold water is also nice, but damn, bring a towel after because some major shrinkage is gonna happen. But would recommend.
