Sleep patterns, plasma proteins and aging hallmarks in UK Biobank adults
In UK Biobank adults, longer total sleep, more deep sleep and more REM sleep were associated with lower risk of most aging hallmarks, while more wakefulness after sleep onset and greater sleep irregularity were associated with higher risk. These are associations, not causes. [1]

The key findings
Longer total sleep, more deep sleep and more REM sleep were associated with lower risk of most aging hallmarks. [1]
Higher wakefulness after sleep onset and greater sleep irregularity were associated with higher risk, while light sleep showed no significant associations. [1]
Overlapping proteins ranged from 1 to 558 and were predominantly enriched in immune and inflammatory pathways. [1]

Sleep and aging hallmarks in UK Biobank adults
The study asked how objectively measured sleep relates to hallmarks of aging and to shared protein signatures, which the authors describe as poorly understood. It used wrist-worn accelerometer data, plasma protein profiles and health records from UK Biobank participants. Six defined sleep patterns were examined against nine established hallmarks of aging. Longer total sleep duration, greater deep sleep and increased REM sleep were associated with lower risk of most hallmarks. Higher wakefulness after sleep onset and greater sleep irregularity were associated with higher risk, while light sleep showed no significant associations.

Overlapping proteins enriched in immune pathways
The researchers also identified proteins jointly associated with both sleep patterns and aging hallmarks. The number of overlapping proteins varied substantially across the sleep–hallmark associations, from 1 to 558. These proteins were predominantly enriched in immune and inflammatory pathways. Several proteins, including IL1RN, FABP1, GDF15 and LEP, appeared consistently across multiple sleep patterns and aging hallmarks.

Hypothesis-generating scope of the abstract
The authors state that these findings may help generate hypotheses about shared underlying biological processes between sleep and aging. The abstract reports associations only; it does not show that changing sleep changes aging hallmarks. Only the abstract was reviewed, not the full text, so details of design, sample size, follow-up and adjustment are not confirmed here.

How to interpret this
Abstract only; the full text was not reviewed. The abstract reports associations, not causal effects, and does not confirm design details, sample size, follow-up or adjustment.
Based on the study abstract; the full paper, tables and supplementary data were not reviewed.
