The study examined what researchers call behavioral social rhythms: the regularity of daily timing for waking, eating, working or studying, socializing, and going to bed. Older adults are not the only ones exposed. The study population was older adults, so any extension beyond that group is inference rather than finding. They also do not carry the side effect profile of sleep medication, which is a meaningful consideration in older adults given falls and cognitive effects. Anyone weighing whether to start or stop a sleep medication should have that conversation with a prescribing clinician rather than adjusting on their own.
