Objective: Detection of sensitive signs in many work environments with automated systems (aviation industry, flight safety tower, maritime industry, monitoring in the military industry, etc.) is essential and requires constant visual attention. Therefore, the aim of this study was to investigate the effect of forehead cooling on the accuracy of stable visual attention.Methods: This interventional study was performed on 34 male students. The sampling method was randomized block design. Subjects were assessed by demographic questionnaire, Snelln chart, Spiel Berger State-Trait Anxiety Inventory (STAI) and physiological and cognitive measurements.Results: Pre-frontal cortex cooling caused significant changes in sublingual temperature during 4 measurements in the intervention group. There were no significant changes in heart rate, diastolic blood pressure and Saturation of Peripheral Oxygen(%SpO2) between the two groups. Critical Flicker Frequency(CFF) as an indicator of cognitive fatigue showed that cognitive improvement after pre-frontal cortex cooling occurred following a reduction in cognitive fatigue.Conclusions: Considering the importance of choosing non-invasive methods to improve the operator’s cognitive skills while performing cognitive tasks in the field of neuroergonomics, it can be concluded that prefrontal cortex cooling is an effective and safe way to improve some cognitive skills such as visual attention.
