Abstract:

Performing exercise in the heat can increase the risk of health complications, especially among middle-aged and older adults who have impaired whole-body heat loss (WBHL) relative to young adults.1 That risk may be higher among patients with type 2 diabetes due to abnormalities in cutaneous vasodilation and sweating, which facilitate WBHL.2 However, repeated brief exercise for 7 days or more during heat exposure (heat acclimation) may mitigate this risk by enhancing WBHL.3 We therefore assessed whether type 2 diabetes impairs heat loss in physically active middle-aged and older adults during exercise heat stress and whether heat acclimation could offset any impairment.
