Time spent in outdoor light is associated with mood, sleep, and circadian rhythm-related outcomes: A cross-sectional and longitudinal study in over 400,000 UK Biobank participants

What this work gives Aellic

UK Biobank, median 2.5 h of self-reported daytime outdoor light: each additional hour was associated with greater ease of getting up (95 % CI of the OR 1.46–1.49), less frequent tiredness (0.80–0.82), fewer insomnia symptoms and an earlier chronotype. Self-reported and mostly cross-sectional; the dose unit is hours, and no 30-minute threshold was tested.
