Shivering generates internal heat through rapid muscle twitches

Involuntary muscle contractions burn energy to maintain stable body temperature

When core body temperature dips below normal, the brain triggers involuntary muscle twitches known as shivering. These rapid contractions increase cellular respiration in muscle tissue, converting stored metabolic energy into thermal energy to warm the body.
