Walking more may bring better sleep, a new study suggests.
While previous research has looked at the role of high-impact exercise on sleep, this is one of the first to look at how daily walking relates to sleep in adults between the ages of 30 and 60.
For the study, the researchers enrolled 59 people with an average age of 49 and asked them to take an additional 2,000 extra steps per day — roughly equivalent to a mile — every week over the course of four weeks. Participants wore Fitbits to track their activity.
"Middle-aged or older adults are not always able to engage in high-impact exercise, and these age groups are more likely to have poor sleep," says Alycia N. Sullivan Bisson, first author of the study and a doctoral candidate in psychology at Brandeis University. "So, we wanted to see if something more feasible like walking could make a difference."
