Research Design Connections: Beware of High Temperature Walks
Asano and colleagues learned that walking in hot outdoor environments can harm subsequent cognitive performance indoors; this finding supports creating more temperature controlled indoor walking areas in office complexes and similar locations. The research team reports that “In the experiments [conducted], a total of 96 participants took a mathematical addition test in an air-conditioned room before and after walking in an actual outdoor environment. Results of the experiments showed that walking outdoors under heat-stressful conditions (UTCI ≧ 44 °C) for 15 min decreased the cognitive performance (percentage of correct answers to numbers of problems solved) by 3.6% compared with that before walking. An analysis focusing on the sleep duration showed a negative relationship between sleep duration and the decrease in cognitive performance. This tendency became particularly clear among the participants whose sleep duration was less than 5 h. The reduction of cognitive performance was more pronounced in male participants than in female participants. Sleep-deprived men who …
