Detailed explanation-1: -Hibernation is a hypothermic condition when animals save energy during cold seasons by lowering body temperature, metabolism, breathing, and heart rate. This makes it possible for an animal to survive the winter on a fat deposit that would not last the winter.

Detailed explanation-2: -Hibernation is a deep sleep that helps them to save energy and survive the winter without eating much. During hibernation the animal’s body temperature drops, and its heartbeat and its breathing slow down so that it does not use much energy.

Detailed explanation-3: -Hibernation may last days, weeks, or months-depending on the species, ambient temperature, time of year, and the individual’s body-condition. Before entering hibernation, animals need to store enough energy to last through the duration of their dormant period, possibly as long as an entire winter.

Detailed explanation-4: -This process of artificial cooling in humans appears similar to spontaneous torpor in animals in that it includes reduced breathing, heart rate and metabolism.
