One of the most remarkable adaptations found in nature is the ability of certain animals, such as the Arctic ground squirrel, to enter a state of hibernation that allows them to survive extreme cold. During this period, their body temperature can drop to below freezing, and their heart rate slows to as little as one beat per minute. This process, known as torpor, enables them to conserve energy and survive on fat reserves during the harsh winter months when food is scarce. Interestingly, they can also wake intermittently during hibernation to eat any stored food, which helps to maintain their energy levels. This incredible adaptation not only highlights the resilience of wildlife in extreme conditions but also provides insights into potential applications for human medicine in managing hypothermia and other temperature-related conditions.
