MODEST REDUCTIONS IN FACE SKIN TEMPERATURE DO NOT IMPROVE TOLERANCE TO A SIMULATED HEMORRHAGIC CHALLENGE IN EXERCISE HEAT STRESSED INDIVIDUALS
Face cooling is associated with autonomic and cardiovascular alterations that accompany an increased blood pressure. Cooling the face increases in parasympathetic activity resulting in reductions in heart rate abate after ~3 minutes while increases in sympathetic activity throughout the stimulus cause increased in vascular resistance, resulting in increased blood pressure. Following an exercise heat stress, even minor increases in heart rate and vascular resistance may permit an improved blood pressure control during a simulated hemorrhagic challenge (Lower Body Negative Pressure; LBNP) and ...
