The hibernation is a state of lethargy that allows mammals to withstand the rigors of the cold. When an animal hibernates, its body is produced in a series of physiological changes, such as reduced metabolic activity, lower body temperature and decreased heart and breathing rhythms. A large part of your body stops, and the movements are almost nil. For example, when a squirrel hibernates, breathes four times per minute, while it does in a normal state between 100 and 200 times, and his heart beats 10-20 times per minute instead of making beats 200-300. During the winter, many animals use to sleep, or go into torpor, a state similar to hibernation, and thus overcome the low temperatures and food shortages.
