Cover your vents
The vents around your home can let the cold air in, or let the warm air out. You’ll notice you have some on the walls near the floor. Push large furniture, like couches or beds, in front of those. This way you’ll block the vents, and trap warm air inside. (Side note: if you do use a thermostat, then you’ll want to move furniture away from the vents to let the hot air move through the room).
