Hibernation works by drastically slowing an animal's metabolic functions, including a drop in body temperature, heart rate, and breathing.

To prepare, animals build up fat reserves by eating extra food in the months leading up to hibernation.

After fat build up, they find a safe, secure location like a den to enter their dormant state.

During hibernation, this stored fat provides the energy needed to survive until they wake up in the spring.

Body temperature can drop to near freezing in some species, and their metabolic rate decreases dramatically.

The heart beats and lungs breathe much more slowly to conserve energy.

The stored fat is slowly used for energy to keep the animal alive. Some animals may periodically wake up.

As the environment gets warmer, the animal gradually wakes up, and its body functions return to normal.
