Ha, yes that’s a funny line. I think what they’re getting at is that in order to reduce your core temperature, your body will move hot blood to your skin and extremities, raising their temperature (and making you feel hot!). This increases the temperature difference to your surroundings and therefore speeds up heat loss.
