Seasonal variation in mood and the dynamics of sleep, activity, circadian rhythms, and light

2026-05-05

Abstract excerpt

<h4>ABSTRACT</h4> <h4>Background</h4> Mood symptoms vary seasonally, yet the underlying mechanisms remain unclear. We tested whether wearable-derived sleep, activity, circadian, and light exposure patterns mediate seasonal effects on mood in youth with emerging mood disorders. <h4>Methods</h4> We analysed 733 observation periods from 422 Australian youth (mean age 24.3±5.5 years; 63% female) attending early-int...
