Your Daily Rhythms May Help Slow Biological Aging, Study Suggests

A Johns Hopkins study found that older adults with more regular daily rest-activity rhythms tended to show slower biological aging.

Researchers analyzed one week of movement, sleep, and light exposure in 207 older adults and compared it with four epigenetic aging measures.

Fragmented, inconsistent routines were linked to faster aging, while balanced and predictable schedules were associated with healthier aging markers.

The study is cross-sectional, so it cannot prove that routines cause slower aging, but it points to a potentially simple, low-cost way to support healthy aging.
