Afternoon to early evening bright light exposure reduces later melatonin production in adolescents
npj Biological Timing and SleepWhether light exposure during the day reduces non-visual light effects later in the evening has not been studied in adolescents. We investigate whether afternoon-early evening (AEE) light interventions (130 lx, 2500 lx, 4.5 h, compared to 6.5 lx ...

Chronobiology and Mood Disorders [PDF]
Psikiyatride Güncel Yaklaşımlar, 2011 Living organizms show cyclic rhythmicity in a variety of physiological, hormonal, behavioral, and psychological processes. Sleep-wake cycles, body temperature, hormone levels, mood and cognition display a circadian rhythm in humans.

Molecular Clocks in Translational Roadmap for Circadian‐Based Therapeutics in Lung Diseases
The FASEB Journal, Volume 40, Issue 10, 31 May 2026.High‐amplitude circadian oscillations maintain lung immune and epithelial homeostasis. Chronic inflammation dampens peripheral clock amplitude, driving chronodisruption, barrier dysfunction, and remodeling. Clock‐targeted therapies re‐entrain the lung circadian clock, restore rhythmic immune resolution, and promote functional lung repair.

Coupling governs entrainment range of circadian clocks
Molecular Systems Biology, 2010 Circadian clocks are endogenous oscillators driving daily rhythms in physiology and behavior. Synchronization of these timers to environmental light–dark cycles (‘entrainment’) is crucial for an organism's fitness.

Impact of Varying Sleep Pressure on Daytime Sleep Propensity in Healthy Young and Older Adults
Clocks & SleepFixed sleep schedules with an 8 h time in bed (TIB) are used to ensure participants are well-rested before laboratory studies. However, such schedules may lead to cumulative excess wakefulness in young individuals.
