Chronic poor sleep linked to inflammation and faster brain aging
A study published in EBioMedicine, a journal in The Lancet family, linked chronic poor sleep quality to higher inflammation and a larger brain age gap, a sign of accelerated brain aging.

What the research shows
A study published in EBioMedicine, a journal in The Lancet family, reported that chronic poor sleep quality was associated with higher inflammation and a larger brain age gap. This gap is a measure used to indicate accelerated brain aging. The finding describes an association between persistent poor sleep and these markers of brain health.
An association does not prove that poor sleep causes inflammation or brain aging, since other life factors can influence both. The link between sleep, inflammation and cognition over time is a growing area of interest, and this study adds to understanding that connection. The results should be read as a step in research, not a final conclusion.
What it means
The findings suggest a link between long-lasting poor sleep, inflammation and faster brain aging. It is still unclear which way this relationship runs or how much it matters compared with other health factors.
How to read it with care
A single study does not replace a consultation. Anyone considering changes to sleep habits, diet, supplements or treatment should talk to a doctor or another qualified professional.
