Wouldn’t it be nice to be able to stay in bed on the really cold days of winter? Some animals do!
Hibernation is when animals become inactive during colder times of the year in order to conserve energy. They will reduce their body temperature, breathing rate, and heart rate. They do this because in winter it can be difficult to find food, and they may spend more energy looking for food than they would get from actually eating the food!
