Adaptive mechanisms help humans survive extreme cold

The video explains how the body regulates temperature in cold conditions by concentrating blood flow to the core and using goosebumps to retain heat. It also discusses how the metabolic rate increases to generate warmth and highlights the adaptation of people in subarctic regions, like the Inuit, who have higher basal metabolic rates to survive extreme cold.

What happens to the metabolic rate in cold temperatures, and why is this important?

How do the basal metabolic rates of people living in extreme subarctic regions differ from those in warmer climates?
