Does Polar Bear Hibernate?
Polar Bears do not hibernate and remain active throughout the year. The only time polar bears do something resembling hibernation is when a female polar bear makes a den in which to give birth and then take care of her cubs. Other than this polar bears remain active throughout the whole year. The female polar bear’s heart rate slows to about 27 beats per minute from a normal resting heart rate of about 46 beats per minute.
