In addition to the well-known thermoregulatory responses, such as cutaneous vasomotion, sweating, and thermogenesis by shivering and non-shivering, there is also the curious and poorly understood thermally mediated hyperventilation. Previous studies have shown that humans hyperventilate under cooling and ...

This probably was metabolized during growth to warm the baby; brown fat is packed with mitochondria and thereby conducts what is called “non-shivering thermogenesis”. Furthermore, Lyuba has very strange flanges on the trunk (also visible in 1 other frozen mammoth specimen, but here preserved ...
Taken together, neither BAT nor functional UCP1 in pigs suggests that body temperature regulation in the piglet is independent of BAT-derived non-shivering thermogenesis (NST). In fact, whether the disruption of UCP1 in pig was the primary event leading to the loss of BAT or whether it was...
The most notable of these is the presence of high levels of brown adipose tissue (BAT or brown fat), which contributes to substantial increases in metabolic rate due to non-shivering thermogenesis (Cannon and Nedergaard, 2004). As BAT is present in many mammals (Cannon and Nedergaard, 2004)...

Non-exercise adaptive thermogenesis (NEAT), which is all the calories you burn by doing things like fidgeting or shivering, she explains. It accounts for about 20 percent of your metabolism, and it can vary from day to day depending on things like what you’re doing or what you're eating...
Heat production is increased by such muscle activity as moving or shivering. In some mammals, certain hormones can cause mitochondria to increase their metabolic activity and produce heat instead of ATP. This nonshivering thermogenesis (NST) In paragraph 2, the author explains the concept of ...
