Hibernation


All creatures that inhabit the Earth, both plants and animals, move within a system of harmony, in which they are able to stay alive, based on the qualities they possess. Likewise, these must adapt to the conditions that their environments acquire, in certain periods. This is how these, during the boom, reserve all the energy possible, to stay alive while the months of low productivity pass. However, they can also implement some changes in the functioning of your body, regulating certain actions, such as breathing and heart rate; this is in order to preserve as much energy as possible. This is the case of hibernation or, as it is also known, the “winter sleep”.

Hibernation is one of these methods of preservation through adaptation, put into practice during the winter months. Different species implement it in different ways, but, in general terms, it is characterized by a metabolism whose functioning is decreasing, accompanied by a very low body temperature and a slow respiratory rate. This is the solution to the hard life of the colder months, and it can work for days, weeks and months. Warm-blooded animals, also known as homeotherms, are the ones most likely to have this peculiar characteristic, in addition to some cold-blooded ones, such as ladybugs.

As mentioned above, each animal, depending on its characteristics and blood type, may go into hibernation in a different way. Even so, it is known that homeothermic animals enter into a previous preparation of even several months, when the temperature begins to drop. This is how the sleep cycle begins; some animals, even with a somewhat rough handling, do not wake up, giving the impression that they are no longer alive.
