Physiological responses to acute cold exposure
When exposed to mild cold, the body's non-shivering thermogenesis (NST) plays a crucial role in increasing calorie-burning, mainly by using fats for energy

When exposed to mild cold, the body's non-shivering thermogenesis (NST) plays a crucial role in increasing calorie-burning, mainly by using fats for energy. This effect is likely due to both skeletal muscles and brown fat working together. On the other hand, white fat under the skin doesn't seem to play a significant role in NST. The biggest changes in NST occur during the first 30 minutes of cold exposure, when discomfort is lowest.
