A total of 788 people (aged from 60 to 93 years) living in the Okinawa prefecture, renowned for the long life expectancy of its citizens, were randomly chosen as subjects. A questionnaire based on lifestyle and sleep‐health was distributed. Following this, subjects were chosen in groups of nine from the good sleep‐health group and then from the poor sleep‐health group based on the results of the survey; their physical activities were then recorded using actigraphs for 1 week. This study suggested that lifestyle, such as exercise, walking and short naps, occupies an important position in the maintenance and improvement of sleep‐health. It also verified the reliability of the sleep‐health risk index and the questionnaire.
