In the true sense of the word, polar bears do not hibernate. While true hibernators experience a noticeable drop in heart rate and near 320F (00C) body temperature, polar bears do not. Instead, they experience what is known as "walking hibernation." In the fall, pregnant females enter the den, but males and non-pregnant females don't. They give birth to their cubs in the den in November or December. In March or April, the mother and cubs emerge from the den. They live in the Artic, which is always cold, so there wouldn't be much point in hibernating.
The females den up in winter to give birth, but males remain active in all but the worst weather.
Yes, they are just like other bears.
Polar Bears do not ordinarily hibernate. When the temperature drops during the winter, many Polar Bears enter a state where their body functions will slow. This lethargy, drop in the body temperature and drop in respiration rate, are referred to as the "winter sleep". The Polar Bears are easily disturbed and awakened, and a female can give birth, and care for her young, while she is in this "winter sleep". Many times the degree of the inactivity or the depth of the "winter sleep" appears to be related to the weather, and the individual bears fat reserves. For more details please see sites listed below.
