In the 1800s, people had to rely on a variety of methods to keep warm during the harsh winter months. One common way was to layer clothing, with women wearing multiple petticoats and men donning thick wool coats. They also used bed warmers filled with hot coals to heat up their beds before climbing in for the night. Additionally, families often gathered around a central hearth or fireplace to stay warm, with some even sleeping near the fire for added heat. Other methods included using hot water bottles, heating bricks and rocks, and wearing fur-lined garments. Despite the lack of modern heating systems, people in the 1800s found creative ways to stay warm during the coldest times of the year.
