The Chill Switch: How Some Animals Control Body Heat to Weather Extremes

Some mammals and birds can deliberately alter their internal temperature through heterothermy, using short bouts of torpor or longer hibernation to conserve energy and water during harsh weather, predators, or food shortages. Studies highlight bats, sugar gliders, dormice, and other species adjusting torpor in response to wind, rain, predators, and even moon phase, showing a flexible survival strategy beyond normal body temperature control. This helps them endure variability, though it isn’t a foolproof shield against climate change.
