| Video Discription | Body shivering, teeth chattering, why does our body descend into a twitching mess in the cold? If you are looking for an answer to that question, you have come to the right place! In this video, we reveal to you in simple terms the scientific reason why we shiver. So make sure to watch this video till the end and subscribe to YourHealthTV to get videos like this recommended to you every week. When it gets cold out, goosebumps start to rise, teeth chatter, and shivering sets in. It turns out that shivering is an adaptation we have maintained to increase the amount of heat in our body. Let’s take a look at how this odd jerky motion performs thermogenesis—the creation of heat. Humans and other mammals are endotherms, which means that they constantly regulate their body temperature within a certain range. This is in contrast to ectotherms, which generally conform to or tolerate environmental temperatures and therefore experience a wider range of body temperatures. Being an endotherm has its advantages and disadvantages. While an ectotherm is reliant on environmental temperatures for effective foraging and predator avoidance, an endotherm can maintain favorable body temperatures by generating its own body heat. However, constantly producing heat requires a lot of energy that then cannot be used for growth or reproduction. This results in a trade-off between high energy costs and increased function in cold environments. Mammals like us have evolved with the endothermic strategy. As a result, many of our physiological processes and the molecular components that comprise them (e.g. enzymes) are adapted to function in a strict range of temperatures that reflect our normal body temperature. In humans, this range is 95-104˚F or 35-40˚C.
