Thermogenesis

Thermogenesis (/θɜːrməˈdʒɛnɪsɪs/, from Greek θέρμος, thermos, "heat" and γένεσις, genesis, "creation") is the process of heat production in organisms. It occurs in all warm-blooded animals, and helps to maintain body temperature and prevent hypothermia.

Etymology

The term "thermogenesis" is derived from the Greek words "thermos" which means heat, and "genesis" which means creation. It was first used in the late 19th century to describe the heat production process in living organisms.

Types of Thermogenesis

There are three types of thermogenesis: shivering thermogenesis, non-shivering thermogenesis, and diet-induced thermogenesis.

Shivering Thermogenesis

Shivering thermogenesis is the production of heat in response to cold exposure. It is caused by the rapid contraction and relaxation of muscles, which generates heat.

Non-Shivering Thermogenesis

Non-shivering thermogenesis is the production of heat without the involvement of muscle contractions. It is primarily carried out in the brown adipose tissue (BAT), a type of fat tissue that is specialized for heat production.

Diet-Induced Thermogenesis

Diet-induced thermogenesis is the increase in energy expenditure above the resting metabolic rate due to the cost of processing food for storage and use. It is one of the ways that the body burns calories and helps to control body weight.
