Cellular … WebShivering is caused by involuntary contractions of your muscles. Muscle contractions require energy from respiration which releases heat. This heat is used to warm the body up.
WebThe heat produced by nonshivering thermogenesis is mainly a by-product of fatty acid metabolism, but to a minor degree it can also result from glucose metabolism. The activation of brown fat metabolism results in an increased proportion of the cardiac output being diverted through the brown fat. WebIt is used to generate heat by non-shivering thermogenesis, and makes a quantitatively important contribution to countering heat loss in babies which would otherwise occur due to their high surface area-volume ratio.
