Programme 4 - Temperature
Getting hot at the gym might feel uncomfortable, but our bodies are working hard to keep our core temperature stable. A few degrees above or below our normal 37C and we would die.
This week, Graham talks to polar explorer Dr Mike Stroud about the perils of frostbite, and to hyperhydrosis patient Justine, who suffers from excess sweating.
