English: Animals hibernate as a survival strategy to conserve energy and endure harsh conditions during the winter months. During hibernation, an animal's metabolic rate slows down significantly, allowing it to survive with minimal food intake. Many animals, such as bears, groundhogs, and bats, enter a state of hibernation to avoid freezing temperatures and scarce food sources. Their heart rate drops, their body temperature decreases, and their breathing becomes shallow as they enter a deep sleep-like state. This dormant period can last for weeks or even months, depending on the species and environmental conditions. Hibernating animals typically find a secure and sheltered location to spend the winter, such as a burrow, cave, or hollow tree. When spring arrives and temperatures rise, these animals slowly awaken from hibernation, relying on their stored fat reserves to regain energy and resume normal activities.
