Staying warm
If your electricity is cut off during the cold season, your home will quickly chill down. Most important is to have water, food and heat and to be able to receive information from the authorities and media. Households that have wood-burning stoves can keep the house warm and comfortable.
The alternative
Gather everyone in a room, hang blankets over the windows, cover the floor with rugs and build a tent over a table to keep in the heat. Consider fire hazards. Turn off all the lights and alternative heat sources before you go to sleep. Let fresh air in regularly to get oxygen.
