Hibernation, also known as 'winter sleep', is a state of deep sleep or dormancy that an animal undergoes during the cold months of winter. During this phase, body metabolism and heart rate of the animal go down drastically and the animal practically sleeps for various days to months.
There are two types of hibernation, namely 'true' hibernation and torpor, or temporary hibernation. In true hibernation, the animal falls into such a deep sleep that it appears to be dead. The body temperature, breathing, and the heart rate drops down. Torpor is a state of short sleep, where the heart rate and body temperature goes down but the animal is able to move around. There are various types of hibernation and not all animals go into a complete state of hibernation.
