Why Humans Don't Hibernate

Humans don't hibernate because our ancestors lived in warm places and didn't need to.

They found other ways to stay warm, like using fire and clothes.

But scientists think some ancient humans might have spent winters sleeping in caves, which is a bit like hibernation.

Now, researchers are studying if humans can hibernate in the future.

This could help astronauts on long space trips and patients in hospitals.

It's like something out of a science fiction movie, but it might become real soon!
