Hibernate

Hibernate is a natural state in which some animals slow their metabolism and become less active to survive harsh environmental conditions, typically during winter. During hibernation, these animals reduce their heart rate, breathing, and body temperature to conserve energy when food is scarce. Common hibernators include bears, ground squirrels, and certain species of frogs. Instead of sleeping continuously, hibernators may wake briefly during the winter, but their overall activity is significantly reduced, allowing them to endure long periods without food until warmer weather returns. This adaptability helps them survive in changing climates.
