Abstract

Introduction: In many workplaces, there is exposure to HEAT and light simultaneously. This study investigated the COMBINED EFFECT of HEAT and LIGHTING on some cognitive performances, i.e. REACTION TIME.Methods: The present semi-experimental study was conducted in 2015 on 33 healthy students (16 girls and 17 boys) with a mean age of 22.1 in a thermal stress chamber. The REACTION TIME parameter was measured by a REACTION TIME measurement device, after exposure to different HEAT surfaces (dry temperatures of 22°C and 37°C) and LIGHTING surfaces (200, 500 and 1500 lux). Data were analyzed using ANOVA test in SPSS 20.Results: 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, which showed a significant difference (P<0.05). The maximum score of REACTION TIME belonged to 37°C and 1500 lux, the minimum score of REACTION TIME belonged to 22°C and 1500 lux.Conclusions: The results of this study showed that increasing the levels of HEAT and LIGHTING by increasing the REACTION TIME and REACTION TIME error of people can decrease the cognitive performance. Therefore, workplaces must be optimized and attended in terms of HEAT and LIGHTING.
