How does cold exposure affect brown fat?


Cold exposure can significantly affect brown fat by increasing its activity, known as thermogenesis, and enhancing its capability to regulate body temperature and metabolism. explains that cold exposure triggers an increase in brown fat stores and the number of mitochondria within these fat cells, enhancing their ability to generate heat and burn fats, including unhealthy white adipose tissue 1 2. Additionally, shivering induced by cold exposure releases a molecule called succinate, which stimulates brown fat thermogenesis and increases brown fat, thereby enhancing the body's heat production and overall metabolism 3.

Cold Exposure Effects

Andrew discusses a study on the effects of deliberate cold exposure on metabolism in young, healthy men. The study found that 11 minutes of cold water immersion per week increased brown fat thermogenesis and core body temperature, resulting in increases in core body metabolism. The longer-lasting effects of cold exposure on metabolism occur through changes in the types of fat stored in the body.
