Study Notes
Heat Generation in the Body
- Shivering is a mechanism the body uses to generate heat when cold.
- The body also produces heat through a process called non-shivering thermogenesis, utilizing brown fat.
- Brown fat is a tissue that generates heat.
- Brown fat levels are highest in infants when they are most vulnerable to cold.
- Brown fat levels decrease gradually as we age.
- Mitochondria, through a process called proton leak, can generate heat.
