Hibernation is a state of dormancy characterized by a significant decrease in metabolic activity, body temperature, and physiological functions in animals. It is an adaptive strategy to conserve energy and survive harsh environmental conditions, such as extreme cold or limited food availability. Animals in hibernation enter a state of deep sleep, during which their vital functions slow down, and they rely on stored body fat for sustenance. Hibernation is commonly observed in bears, bats, and certain rodents.
