What is a long winter sleep called?

The long winter sleep is known as Hibernation.

The word “hibernation” is derived from the Latin word 'hibernare', meaning, “to pass the winter”. 

Animals like Polar Bears went for hibernation which helps them to survive the changing seasons.

Hibernation functions to conserve energy by slowing down the body function, such as heartbeats and breathing, when sufficient food is unavailable. 

They can survive while a long sleep because their bodies use their stored fat or food for energy.

Except for bear, animals such as squirrels, bumblebees, bats, lemurs, etc. also go on hibernation during winter.
