Researchers at the University of Missouri found that a simple, steady daily schedule can help older people feel better both physically and mentally.
The study looked at adults over 60. Those who kept similar times for waking, eating, working, socializing, and sleeping reported less body aches and fewer sad feelings, even if they had trouble sleeping.
Insomnia, Pain, and Sadness
About half of people over 60 have trouble sleeping. The researchers asked 67 volunteers about their sleep and health. Thirty‑seven of them said they often could not fall asleep.
As expected, the sleepless participants felt more pain and were more down‑hearted. However, the team noticed that participants who followed a regular routine felt less pain and were less depressed, no matter how well they slept.
"If we wake up, eat, work, and go to bed at about the same times each day, our internal body clock stays in sync," said lead researcher Eunjin Tracy. "That sync seems to protect health over time."
How Routines Help the Body Clock
Doing the same things each day sends clear signals to the circadian rhythm, the body’s 24‑hour clock. This clock controls sleep, mood, and many other functions.
When the clock runs smoothly, the body works well. Small changes—like sleeping in on weekends—can throw the clock off. This is called “social jet lag.”
Keeping a similar schedule every day, even on weekends, can reduce this disruption and keep the clock steady.
The Impact of Social Jet Lag
Tracy explained that a consistent routine can help people of any age. She said, "One‑third of our lives is spent sleeping, so we should think about health in a full‑day way, not just when we are awake."
The findings suggest that a predictable daily rhythm is an easy way to improve health, especially for older adults who have insomnia. Instead of focusing only on nighttime sleep, researchers should also look at how daytime activities affect the body’s clock and overall well‑being.
The study, titled "Behavioral‑social rhythms and insomnia symptoms: associations with pain, body mass index, and depressive symptoms among older adults," was published in the Journal of Behavioral Medicine.
