With the exception of pregnant females, polar bears do not hibernate. Instead adult male polar bears and non-pregnant females remain active throughout the year. They nap during the day and sleep 7 to 8 hours a night.
No, there is no evidence that polar bears sleep in the water. A sea otter can sleep on water, floating on its back, but a polar bear's body density makes this impossible.
same same
sleep all day long.

Only a couple of hours.
yes, they are smaller and have not as much hair ;)
Polar bears are carnivorous. Panda bears are nearly complete herbivores. Polar bears are also much larger than pandas.
polar bears sleep by digging holes in the snow and sleepig in it. the snow that builds up on top of them keeps them acts as a sort of blanket. snow is actually a very good insulator and thus keeps them warm
Koalas (which are not bears at all, but marsupials) sleep for between 16 and 21 hours a day. This is more than polar bears, which sleep for an averge of 8-9 hours a day.
Live. Hunt (and sleep) remember that polar bears live where there may be "night" (no sun) for several months running!SLEEP
As much as they want to have.
Other types of bears can climb trees and can survive in warm temperatures. These are not things that polar bears can do.
