Winter can be a chilly time! Some animals have clever ways to stay safe and cozy when the weather gets cold and food is hard to find. They do this by taking a long winter nap called hibernation!

What is Hibernation?

Hibernation is like a super long sleep. During hibernation:

  • Animals slow down their breathing.
  • Their heart beats much slower.
  • They use less energy.

This helps them survive the winter without needing to eat much, or even at all!

Who Hibernates?

Lots of different animals hibernate. Here are a few examples:

  1. Bears: They sleep in dens, sometimes for many months!
  2. Groundhogs: These furry friends dig burrows underground and snooze the winter away.
  3. Snakes: Some snakes gather together in a safe place, like a cave, and hibernate together.

Wow, that's a long nap!

Isn't it amazing how animals adapt and survive? Learning about nature is so much fun! Keep exploring and asking questions about the world around you!
