Can humans hibernate?
Hibernation is a response to cold weather and reduced food availability. Most animals that hibernate are quite small and, as the weather gets colder, they reach the point where they simply can’t eat enough food to sustain their body temperature. Humans don’t hibernate for two reasons.

Is hibernation sleeping for months?
A) Bears hibernate during winter, but aren’t sleeping the whole time. Hibernation for bears simply means they don’t need to eat or drink, and rarely urinate or defecate (or not at all).

Why is my hamster shaking with eyes closed?

What does hibernation feel like?
