| Research Abstract |
To prevent such individuals with spinal cord injuries from becoming hyperthermic, we developed a body heat removal system (BHRS) with thermoelectric devices. We characterized thermophysiological responses induced by the cooling system. A cooling experiment in a hot environment with able-bodied subjects demonstrated that sweating and systolic blood pressure in the back-cooling (BC) trial were significantly suppressed compared with those in no-cooling (NC) trial. A correlation was observed between chest skin temperature and blood flow in the NC trial; this was not observed in the BC trial. These results suggest that BHRS modulates normal thermoregulatory responses, including sweating and vascular dilation and has the capability to partly replace these functions.
