A method to evaluate cognitive impairment under high temperature based on temple skin temperature

The study aimed to explore temple skin temperature as a potential physiological indicator reflecting the impact of high temperatures on cognitive performance. The feasibility of this indicator was substantiated through a thorough analysis of climate-controlled experimental data conducted at varying high temperatures: 33 C-degrees, 37 C-degrees, and 39(degrees)C. The temple skin temperature was carefully monitored during the experiments, alongside cognitive tests that measured work memory, concentration, and neurobehavioral abilities. In total, 1459 valid samples were collected, contributing to the robustness of the study. The results elucidated a noteworthy finding: a significant decline in cognitive test accuracy commenced when the temple skin temperature reached 37 C-degrees (p < 0.05). Intriguingly, the correlation between the relative accuracy of cognitive tests and temple skin temperature showcased a distinctive inverted U-shaped pattern. Employing a quadratic regression model facilitated the quantification of this relationship, yielding coefficients of determination (R-2) for the fitted models that were close to or exceeded 0.9. These findings imply that temple skin temperature can be used to assess the effect of high temperature on cognitive performance. Furthermore, this research suggests the promising prospect of employing temple skin temperature for real -time monitoring of job safety in high-temperature environments.
