Understanding Animal Hibernation

hibernation is an inactive condition which decreases metabolism in animals and body temperature will decrease lower, breathing will decrease more slowly, and metabolic rate will decrease.

These hibernating animals have a purpose as energy savers, especially in the winter when their food is getting stepped up.

By hibernating, the animal can burn energy reserves and body fat slowly.

The same is true according to KBBI (Big Indonesian Dictionary) which explains that hibernation is a state of rest or sleep in animals during the winter.

Function and Purpose of Animal Hibernation


Hibernating animals aim to save their energy during limited food times.

In order to save optimal energy, the endotermic process will react faster than usual so that it can reduce metabolism in the animal’s body.

Then it will continue with a decrease in body temperature in the animal.

Hibernation can take some time depending on the season and food availability.

Can be several days, weeks, months.

This depends on the temperature of the environment, animal species, time of the season, and the condition of the body of the animal.

Hibernation Process


When animals face a hibernation period, they will consume more food than usual.

An example is a bear who does this.

The animals will carry out the hibernation stage in order to store fat reserves in their bodies in the face of the winter.

After waking up from hibernation, they will need some normal activities, some even still sleep like dead.

During hibernation, the heart rate will slow down and other non-vital organs will be completely disabled.

That’s why, hibernation, can be seen in plain view like a dead animal.

Because this condition is also called a minimal energy condition.

Examples Of Animals That Are Hibernating


There are several examples of animals that do not hibernate, there are also some examples of animals that hibernate in winter.

Of course, each animal has a different hibernation mechanism.

Generally, cold-blooded animals will sleep in the summer or dry, which is called estivation, while animals that sleep in winter aka hibernate include bears, porcupines, badgers, hamsters, certain types of mice, squirrels, lemurs, groundhog, beetle, small, and so on.

If seen, it can be concluded that hibernating animals are mostly animals that have thick fur

Dormice Rat

This type of mouse is one type of mouse that also experiences hibernation.

Where this type of mouse can be found in European regions.

When he hibernates, he will look for a safe place to hide from his enemy attacks.

An example is underground.


Like dormice mice, bats also experience a hibernation process.

So that it can be said that not only thick haired animals are experiencing hibernation.

Bats also experience this.

Generally, these animals will colonize their beds in the cave.

However, it is possible that they will also sleep inside the houses.

Especially an uninhabited house.


Bears of all kinds, will hibernate.

Except for polar bears that do live in cold areas.

Well, that’s the definition of hibernation and the example of hibernating animals.

In conclusion, they sleep, does not mean lazy, but they are saving their energy because of the limited food available in winter.
