The Benefits of Cold Exposure: Fat Burning and Stress Inoculation

Stress suppresses the activation of the sympathetic nervous system, which is responsible for the stress response./nCold exposure can be used as a form of stress inoculation and is commonly used in military training./nCold-induced shivering releases a chemical called succinate from muscles, which activates a certain category of fat known as brown fat./nBrown fat is rich with mitochondria and generates heat in the body, increasing metabolism and causing fat burning./nIf using ice baths for increasing metabolism, shivering is encouraged. If using ice baths for stress inoculation, learning to stay calm or muscle through the cold is recommended.
