Investigating the combined effects of heat and lighting on students reaction time in laboratory condition

In many workplaces there is exposure to heat and light simultaneously. This study investigated the combined effect of heat and lighting on some cognitive performance, i.e. reaction time.
the present semi-experimental study was conducted 2015 on 33 healthy students (16 girls and 17 boys) with a mean age of 22.1 in the thermal stress chamber. The reaction time parameter by the reaction time measurement device, after exposure to different heat surfaces (dry temperatures 22 °C and 37 °C) and lighting surfaces (200, 500 and 1500 lux). Data were analyzed using ANOVA test in SPSS-20.
The results showed that the average simple, diagnostic, two-color selective, two-sound selective reaction times and reaction time error increased after combined exposure to heat and lighting and showed a significant difference (P
