When we feel cold, sometimes our body begins to shiver all over.  Why does that happen?

 

Shivering is a way for the body to control the body temperature.  When it gets cold, receptors to different senses on the skin can feel it.  The receptors then send a message along the nerves to the brain.  When the brain receives these messages, it will send messages back to different body parts to react accordingly to regulate the body temperature.  One of the messages tells the muscles around the body to contract and relax, which causes the shivering.  When we shiver, the body will create heat energy to keep the body at the normal body temperature.

 

Therefore, when we feel cold, our body shivers to stay warm.  However, even though this can help us regulate our body temperature, we should also remember to dress properly on cold days so we won’t catch a cold!
