We, humans, are warm-blooded, meaning we can regulate our internal body temperature regardless of the environment. To keep our bodies’ core temperature regulated at 36.5–37.5 °C the process begins in the brain, the hypothalamus is responsible for releasing hormones to control temperature. When you feel cold, sensors in your skin send messages to your brain and Your brain signals your muscles to being shaking rapidly. A shiver is caused by your muscles tightening and relaxing in rapid succession. When muscles move, they generate heat. This involuntary muscle movement is your body’s natural response to getting colder and trying to warm up.
