they dont, there is not a single of species of bear that have ever been known to hibernate. bears torper during winter, this is when they sleep, but can still wake up and walk around, hibernation is when an animal is in a deep sleep for the whole winter and cannot and will not wake up at all. torper is just like a lazy sunday morning when you wake up at 6:00, then fall asleep, then wake up and walk around again, then fall asleep. its the same concept
No bear truly hibernates. However, they often go into a torpor, a deep sleep, and do so when food becomes scarce due to cold or snow cover. Some bears in warmer climates are active all year long. The weather determines when the bear enters a den for the winter, not the calendar.

They store food as fat. This occurs just before hibernation.
It would go against all their survival instincts if they hibernated in the summer They give birth to their young during the hibernation period, in the winter . Being such a large mammal, they need time to nurture their young in relative protection from large males who have no qualms about eating a sows babies. Over the millennial of evolution they have become instinctual about hibernation. By the time the cubs are nine months or so, they have developed enough skills to survive with their mother's help. After they reach the age of two years they go off on their own
