Hibernation is a state of significantly reduced metabolic activity and lowered body temperature that allows animals to survive periods of food scarcity and harsh environmental conditions. This physiological adaptation is observed in various mammals and involves complex changes at the molecular, cellular, and systemic levels.

Hibernation in mammals is a complex, adaptive strategy involving significant metabolic, physiological, and molecular changes. It allows animals to survive extreme environmental conditions and food shortages by entering a state of reduced metabolic activity and body temperature. This process is tightly regulated and involves periodic arousals to maintain essential physiological functions. Hibernation also plays a crucial role in the life-history strategies of many species, contributing to increased survival and longevity.
