Web7 Jun 2024 · Thermogenesis: Your body’s muscles, organs, and brain produce heat in various ways. For example, muscles can produce heat by shivering. For example, muscles can produce heat by shivering. WebThermogenesis means the creation of heat. There are three types of thermogenesis. The first kind is work-induced from exercise. It is necessary for our muscles to create heat because warm muscles work much more effectively than cold muscles. The next form is called thermo-regulatory thermogenesis.
