Animals and Hibernating: Are They Really Asleep?
How do animals prepare for chilly winter temperatures and the food scarcity it brings? Find out about adaptive techniques called hibernation, migration, and dormancy that allows plants and animals to survive winter weather. Many animals snuggle up in caves, burrows holes in the ground , or hollow tree trunks and sleep during the cold winter months when food is harder to find and cold weather makes it harder for their bodies to work. This is called hibernating. When an animal hibernates, its heart beats very slowly and it also breathes less. It takes a long time for a hibernating animal to wake up. Because its body slows down and stops working the way it normally does and because the animal is not moving around and using up energy, its body is able to survive off of the fat that it stored up by eating a lot in the fall.
Certain animal species have evolved an adaptation that allows them to weather long stretches of time when food is scarce — they enter a state known as hibernation. And what happens when an animal hibernates is much more dramatic than simply curling up for an extended nap; extreme metabolic changes are taking place. The animal's heart and breathing rates slow down, and its body temperature drops. Depending on the species, days or even weeks may pass without the animal waking to drink, eat or relieve itself. The word "hibernation" is derived from the Latin hibernare , meaning, "to pass the winter," according to the Online Etymology Dictionary. The term originated in the late 17th century in reference to a dormant state in insect eggs and plants, and was applied to other animals beginning in the 18th century. Today, many types of mammals are recognized as hibernators, including bats, rodents, bears and even primates — three species of dwarf lemur in Madagascar and the pygmy slow loris in Vietnam have been found to hibernate.
Hibernation is a fascinating and weird natural phenomenon. Like most fascinating and weird phenomenon, everyone knows about it and few people know very much about it.

Hibernation is a state of inactivity and metabolic depression in endotherms., How Do Animals Survive Winter?
Every living animal on Earth is burning energy all the time. Physical activities like walking and breathing burn energy. Pumping blood and digesting food burns energy. Even thinking burns energy. For warm-blooded animals, a lot of energy is burned just keeping our body temperature where we need it.
