Cold Exposure for Metabolic Health: Activating Brown Fat Through Temperature Therapy
Beyond its use for recovery and mental toughness, cold exposure is emerging as a powerful metabolic intervention. Regular mild cold stress activates brown adipose tissue (BAT)—a mitochondria-rich fat that burns calories to generate heat. Studies show cold-adapted individuals can increase daily energy expenditure by 200-400 calories through this mechanism while significantly improving glucose metabolism.
