Diagram of the cooling system. This diagram appeared in a previous publication (J Physiol Anthropol 2007, 26: 403–409) and is shown again here to provide details of the system. A chiller cooled the water in the bath and a pump supplied cool water into the vinyl tubes incorporated in the suit. After water was perfused through the tubes, it was returned to the water bath and cooled again.
