Do polar bears sleep in dens?

They may use these shelters for several months at a time..

Can humans hibernate?
Hibernation is a response to cold weather and reduced food availability. … Humans don’t hibernate for two reasons. Firstly, our evolutionary ancestors were tropical animals with no history of hibernating: humans have only migrated into temperate and sub-arctic latitudes in the last hundred thousand years or so.
