Abstract

1. 1.|The effect of moderate heat load on the auditory brain stem response (ABR) was studied in 13 healthy normal subjects. Heat stress was induced by a combined exposure to heat and physical exercise performed in a climatic room. 2. 2.|Significant latency decreases were observed in the ABR waves III and V as well as in the interpeak latency differences (IPLD), indicative of changes at the midbrain area. Latency of waves V and III as well as IPLD V-I and V-III were highly correlated (r = 0.73, r = 0.79 and r = 0.54, respectively) with temperature elevation. 3. 3.|The best fitted curve to latency changes induced by moderate heat stress was found to be quadratic. ABR may serve as an objective neurological measure with clinical applications to the study of heat stress.
