A new study from the University of Missouri reveals that maintaining a consistent daily routine can significantly reduce physical pain and ease symptoms of depression, offering an accessible strategy for improving quality of life, especially for older adults with insomnia.
The Research
Researchers led by Eunjin Tracy, an assistant professor in the College of Education and Human Development, analyzed survey data from 67 older adults, including 37 people with insomnia. The study, published in the Journal of Behavioral Medicine, examined how daily behavioral and social rhythms influence health outcomes. As expected, participants with insomnia reported higher levels of pain and depression. However, the key finding was that regardless of sleep quality, those who maintained consistent daily routines — regular wake times, meal times, work or social activities, and bedtimes — reported lower physical pain and fewer depressive symptoms compared to those with irregular routines.
The stabilizing effect is attributed to better synchronization of the body's circadian rhythm, the internal 24-hour clock that influences sleep, mood, and other biological functions. Regular time cues from daily activities help align this clock, mitigating biological dysfunction caused by schedule disruptions. The study also highlights the concept of "social jet lag" — the mismatch between sleep times on weekdays versus weekends — which can disrupt circadian rhythm even in good sleepers.
Why It Matters
Roughly 50% of adults aged 60 and older experience insomnia symptoms, according to the National Council on Aging. This study suggests that a simple, low-cost behavioral change — maintaining a consistent daily schedule — can buffer against the negative health impacts of insomnia, reducing pain and depression. For anyone concerned about cognitive health, stable circadian rhythms are linked to better memory, attention, and emotional regulation. This research underscores that our daily habits, not just our sleep quality, play a crucial role in brain health.
What You Can Do
Try to wake up, eat meals, and go to bed at the same time every day, including weekends. Keep a consistent schedule for work, social activities, and exercise. Even small routines, like a regular morning walk or fixed dinner time, can help synchronize your internal clock and improve well-being.
