Sleep health and lifestyle of elderly people in Ogimi, a village of longevity.

The study was conducted in the Prefecture of Longevity, Okinawa, on the elderly living in the village of Ogimi. It was revealed that those in the good sleep health group took short naps, a significantly fewer number fell into dozes, and a significantly greater number exercised regularly or walked. A significantly greater number of this group maintained regular eating habits over a 10-year span, and consumed more seaweed and fish. Participation in senior citizens' clubs was higher, reflecting high emotional adaptability. The study's results indicates a relationship between lifestyle and sleep health among the elderly, and suggest that deterioration of sleep health is related to physical and mental health.
