Heat illness is potentially life-threatening and poses an occupational hazard for firefights and military personnel who have to exert themselves in hot, humid environments. The purpose of this study was to examine how circulating concentrations of IL-6, IL-10, IL-1ra, and IL-1ß responded to temperature and humidity during aerobic exercise. Twelve college-age men completed six experimental trials: a VO2max test, and cycling in five conditions: 5ºC/passive humidity (LTLH), 22ºC/45% humidity (MTMH), 22ºC/70% humidity (MTHH), 35oC/20% humidity (HTLH), and 35oC/45% (HTMH). The environmental trials involved cycling for 60 minutes at 60% VO2max, resting for 15 minutes, cycling at 90% VO2max until exhaustion (TTE), then recovering for 60 minutes in the same temperature condition. Blood was obtained prior to exercise (PRE), after 60 minutes of cycling (60), after the TTE (90), and after recovery (REC). Blood was analyzed for serum levels of IL-6, IL-10, IL-1ra, and IL-1ß. There was a time effect for IL-6, IL-10, and IL-1ra in all conditions except LTLH. The increases in IL-6 were during exercise, at 60 and 90. For IL-10 and IL-1ra, the increases were at 90 and REC, respectively. The increases in IL-6 and IL-1ra were enhanced in HTLT and HTMH. For IL-1ß, there was only a time effect at LTLH. The IL-6 response indicates an inflammatory response to exercise that is enhanced in the heat. The delayed response of IL-10 and IL-1ra and the lack of response of IL-1ß in the heat, indicates that the exercise-induced anti-inflammatory response outweighs the pro-inflammatory response to heat.
