Daily routine improves sleep quality

LOS ANGELES - For older adults, keeping a daily routine may prevent insomnia and improve sleep quality, according to a new study.

The researchers, from the University of Haifa in Israel, said it's more likely that humans benefit from synchronization between their daytime and nighttime activities.

The study of people living in a retirement community showed that stability in the timing, frequency and duration of daily activities like watching TV, reading, bathing, dressing and eating was more strongly associated with sleep quality than stability in activities like shopping or keeping appointments.

More research is needed, the authors said, to understand whether good quality sleep leads to stable lifestyle routines or stable lifestyle routines lead to restful nights. The study is published in the journal Sleep.
