TL;DR: In this article, the authors examined whether dynamically changing light across a scheduled 16-h waking day influences sleepiness, cognitive performance, visual comfort, melatonin secretion, and sleep under controlled laboratory conditions in healthy men.

Changing color and intensity of LED lighting across the day impacts on human circadian physiology, sleep, visual comfort and cognitive performance

TL;DR: The results support the recommendation of using blue-depleted light and low illuminances in the late evening, which can be achieved by a dynamically changing daylight LED solution.
Wide awake at bedtime? The effects of caffeine on sleep and circadian timing in teenagers - a randomized crossover trial

TL;DR: In teenagers, evening caffeine intake of already 80 mg (i.e. ∼8fl oz of common energy drinks) is sufficient to promote alertness at the costs of subsequent sleep, consequently hampering the balanced interplay of sleep-wake regulatory components.

Wide awake at bedtime? Effects of caffeine on sleep and circadian timing in male adolescents - A randomized crossover trial.
Carolin Reichert,Simon Veitz,Miriam Bühler,Georg Gruber,Gunnar Deuring,Sophia Rehm,Katharina Rentsch,Corrado Garbazza,Martin Meyer,Helen Slawik,Yu-Shiuan Lin,Janine Weibel +11 more
TL;DR: The results suggest that 80 mg caffeine are sufficient to induce alertness at a subjective level, however, particularly teenagers with a strong need for deep sleep might pay for these subjective benefits by a loss of SWS during the night.
