Detailed explanation-1: -When the animal’s body systems slow down it goes into a sleep-like state called torpor. Torpor in the summer is called estivation. Torpor in the winter is called hibernation.

Detailed explanation-2: -Despite what you may have heard, species that hibernate don’t “sleep” during the winter. Hibernation is an extended form of torpor, a state where metabolism is depressed to less than five percent of normal.

Detailed explanation-3: -Oversleeping is called hypersomnia or “long sleeping.” This condition affects about 2 percent of people. People with hypersomnia might require as many as 10 to 12 hours of sleep per night to feel their best.

Detailed explanation-4: -Hibernation is a way animals conserve energy to survive adverse weather conditions or lack of food. It involves physiological changes such as a drop in body temperature and slowed metabolism.

Detailed explanation-5: -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.
