Why we shiver when we feel cold
[edit]We shiver because our body tries to keep us warm. Our core body temperature is about 37 degrees Celsius or 98.6 degrees Fahrenheit. A part of our brain called hypothalamus controls and maintains the core body temperature. Usually during cold months, the temperature is quite low. Hence, if we have not worn any warm clothes, we feel cold. Our body temperature starts to decrease. This decrease in temperature is instantly detected by our hypothalamus. Thus, it sends signals to our muscles to contract and relax rapidly, making us shiver. This rapid contraction and relaxation of our muscles generates heat. This heat warms our body. Thus, helping us maintain our core body temperature.
