In this study, temporary stimulus to restore the arousal level and performance of office workers was examined. From the results of the preliminary experiment, two kinds of airflow were selected. Then, an experiment was conducted to verify the effects of these airflows. The number of the participant was nine in the experiment. They conducted cognitive tasks in the experiment and the work efficiency of the participants was measured from the work results. The participants answered a questionnaire at the end of the task, and subjective assessment of airflow was examined. During the cognitive task, the physiological index was measured, and the airflow was exposed by detecting the decrease in the arousal level of participants. Based on the experiment, the measured results for the six participants were analyzed. Comparing between before and after exposing the airflow, the performance recovery effect due to the proposed airflows’ exposure would continue for 15 seconds. As a limitation of this study, the results were based on the experimental results of 6 participants. In the future, in order to further sustain the recovery effect by airflow, the proposed airflow stimulus will be improved. Then, it is conceivable to study an experimental design that exposes the airflow before the arousal level decreases. By improving the duration of recovery effect of airflow stimulation, the greater performance recovery effect will be expected.
