The length of time spent in hibernation varies depending on the animal species. What Happens During Hibernation?ĭuring hibernation, animals conserve energy by reducing metabolic rates and body temperatures. Hibernation allows animals to conserve energy while waiting out harsh weather conditions. Others just go into a deep sleep for a few days.
Many creatures hibernate during winter because it’s too cold for them to move around. This allows them to survive long periods without food or water. They go through a period of reduced metabolism and body temperature, and their heart rate slows down. During winter, these animals enter into a state of suspended animation, where they stop consuming food or breathing. Hibernation is a natural phenomenon that occurs in some species of mammals, birds, reptiles, and amphibians. So instead, they store up fat during the warm seasons, and then enter a state called torpor, where they slow down their metabolic rate and save energy by using their fat stores. However, most mammals cannot afford to spend all year eating, because they need to feed their young during the summer. Hibernating mammals must have enough fat reserves to last through the cold season. It also helps keep body temperature low, which can be dangerous if temperatures rise above normal. Hibernation is an adaptation that allows animals to survive harsh winters when food sources are scarce. This means that they will not eat or drink anything during this time, and may even lose weight. The main thing is that they go into a state where their metabolism slows down, and they use stored fat as energy.
