A thermal camera SLX Merlin record heat in the body of Martin Oli, When he begins undressing in the bitter cold of the Highlands in Scotland. Gradually, the camera allows us to observe the progressive loss of heat from the body that happens in few seconds. As color tends toward the Red, the area is warm. Vice versa, When the color goes gradually towards the green blue and black, the body temperature is much lower. A video from the BBC Earth Unplugged.
