Population-based study shows age affects sleep and circadian timing, implying need for tailored interventions.

This research aims to describe changes in light exposure, sleep timing, and circadian rhythms as people age.
Utilized actimetry data from 404 individuals in the EPISONO cohort (mean age: 49.42 years)
Collected data over 7 days (5 weekdays, 2 weekend days)
Applied generalized linear models to analyze the effects of age on sleep and light exposure timing.
Significant differences in sleep timing across age groups (p<0.001)
Young adults (20-29 years) had later light oM10 compared to those aged ≥40 years (p<0.001)
Circadian phase was also significantly later in younger participants compared to older age groups (p<0.001).

Vallim et al. (2026) studied this question.
