Our body has homeostatic functions that automatically monitor, adjust and regulate our important systems without our even knowing it. Our Shivering is just one of these homeostatic functions our body employs to regulate our body temperature. Also called thermoregulatory shivering, we shiver in an effort to keep ourselves warm. In an attempt to avoid hypothermia where our body temperature is lowered to dangerous levels, our muscles are prompted to contract and expand quickly, resulting in a shiver. This in turn produces more heat in the skeletal muscles to provide extra warmth to our organs. It does use a lot of energy, and severe shivering is a last resort in an attempt to stay warm. Along with shivering, your teeth may chatter due to tightening jaw muscles.
