The paper assesses light exposure patterns in daily life and identifies gaps in meeting recommended illuminance levels, highlighting the need for interventions to improve health outcomes.

The paper develops auxiliary data frameworks and quality control strategies for wearable light loggers to improve data accuracy and interpretability in circadian research.

This study examines how sex and seasonality affect melatonin suppression and alertness to light, finding sex differences and seasonal variations in light sensitivity.

This study finds that afternoon-early evening bright light exposure in adolescents reduces later evening melatonin production without affecting sleepiness or vigilance.

This study tests if cone photoreceptors affect melatonin suppression and alertness to light at night, finding no significant effect.

The paper develops a consensus checklist and guidelines for reporting non-visual light effects in human studies, resulting in a 25-item checklist after expert feedback.
