Recently, we have developed the novel apparatus to provide simulated dawn, and suggested that the simulated dawn by our apparatus have the awakening effect. Thus, this study aimed to investigate the effect on the psychomotor performance. Firstly, we have developed the simple calculation application working on the iPad mini (Apple Inc.). Then, we investigated the effects of the simulated dawn by our apparatus and by another on market in comparison with no light on the psychomotor performance. Each period implemented 5 nights. During the whole period, the calculation test with iPad mini and the St.Mary Hospital Sleep Questionnaire was performed immediately after getting up at 6am, and the 24-hour activity was recorded. Simulated dawn by our apparatus minimally improved the calculation test, but this improvement did not reach statistical significance. Other markers did not change. In conclusion, simulated dawn by our apparatus may have some effect on cognitive performance.
