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 otherwise not last the winter.

Detailed explanation-2: -The term hibernation is often loosely used to denote any state of sustained torpor, inactivity, or dormancy that an organism might exhibit.

Detailed explanation-3: -Hibernation is a seasonal heterothermy characterized by low body-temperature, slow breathing and heart-rate, and low metabolic rate. It most commonly occurs during winter months.

Detailed explanation-4: -Aestivation and Hibernation is one of them. Hibernation is winter sleep whereas aestivation denotes summer sleep. This sleep is different from the normal sleep on other days. During both periods of sleep, the animals chose to have low metabolic activity to restore their body temperature and their energy as well.

Detailed explanation-5: -1 Definition of aestivation. Aestivation is generally defined as a type of dormancy, which is a survival strategy used to sustain lack of food and other extreme conditions (Pinder et al., 1992; Abe, 1995; Storey, 2002). Animals that aestivate become inactive and stop feeding in response to warm temperatures.
