| Abstract(in English) | Recently, seniors who have dissatisfactions of sleep have increased. One of the reasons for this increase is a diminished quality of nighttime sleep and a sleep during the daytime due to age-related changes in circadian rhythm. To this, there is a report that the quality of sleep at night is improved by the amount of activity during the day. So we considered that we might be able to advice sleep for the elderly complain of sleep by knowing how to spend during the day. Therefore, we focused on the state of wake/sleep during the day, we have examined the method of identification the state of wake/sleep objectively in daily life, using the pulse and body movement. First, we conducted free sleep experiments with subjects aged 20 to 70 years under easy-to-snooze environment during the day. We clarify features of the state of wake/sleep during the day that there are momentary sleeps in wake (micro-sleep) and momentary wakes in sleep (arousal response). In addition, pulse interval, during the arousal response, there was a reduce and recovery short-time, during the micro-sleep, there was a increase and recovery short-time. So we suggest the method of sleep/wake identification during the day using these features. In consequence, the data obtained the subjects applied to the proposed method, and the concordance rate of 70% could be made to identify the state of sleep/wake during the day. |
