it cuts it metabolism in half. its sleeping heart rate is about 8-40 beats per minute rather than 60-90. It is a common misconception that bears hibernate straight through the winter. They occasionaly do become active to urinate or possibly even eat food. The bear eats lots of food in the fall and stores the excess nutrients in its fat. When hybernating the bears body processes slow down. The heart beats slower and it uses a lot less energy. It slowly uses up the nutrients stored in the fat until the spring.
