Episode 20 - Chronic Adaptations to Cold

Long-term exposure to cold results in chronic physiological adaptations that improve thermoregulation and energy efficiency. We explore three types of cold acclimatization: Cold habituation – Reduced physiological response to cold over time. Metabolic acclimatization – Increased BAT activity and reliance on fat metabolism for sustained heat production. Insulative acclimatization – Enhanced vasoconstriction and subcutaneous fat to improve heat retention.We also highlight cold adaptation in Arctic populations, its impact on endurance performance, and its practical applications for athletes and military personnel.
