Regular Daily Routines Make Elderly Sleep Better
A study found that the maintenance of daily routines was associated with a reduced rate of insomnia and improved quality of sleep in older adults living in a retirement community.
Results of regression analyses indicate that increased stability in daily routine predicted a shorter time to fall asleep, higher sleep efficiency and improved sleep quality. Stability in basic activities such as bathing, dressing and eating was more strongly associated with sleep quality than stability of instrumental activities such as shopping, public transportation use and medical appointments.
According to the authors, routine lifestyle rhythms may be characterized by stability in the timing, frequency and duration of daily activities such as watching TV or reading a book. It is also possible to identify weekly patterns of regularity in activities such as cleaning, exercise and social engagements.
"We predicted that there would be a relationship between routine activity patterns and sleep quality, since theoretically sleep patterns and other everyday life activities are related and potentially synchronized," said lead author Anna Zisberg. "However, given the widely accepted view that light is the major synchronizer of the human sleep-wake cycle, we were surprised that our findings were so robust."
The study was conducted in the northern part of Israel between August 2007 and September 2008. It involved 96 Russian-speaking older adults in two retirement communities where each apartment was fully equipped as an independent functional unit including a kitchenette. They had a mean age of about 75 years, with a range from 58 to 89 years. Seventy-two percent were female, 82 percent lived alone and 75 percent reported fair or good health. Sleep medication was used less than once a week by five percent of the sample, from once to twice a week by seven percent of participants and three times or more per week by 23 percent of the sample.
Mean total sleep time was six hours, mean sleep efficiency was 77.9 percent and mean sleep latency was 37.53 minutes. Higher sleep efficiency was associated with a more stable duration of basic and instrumental activities and with more stable lifestyle regularity.
The authors noted that changes in the circadian system are considered a natural part of aging and are implicated as an underlying factor of reduced sleep quality in the elderly. Routine lifestyle rhythms may serve as a protective factor contributing to the maintenance of high-quality sleep.
