1	Gender differences in light sensitivity impact on brightness perception, vigilant attention, and sleep in humans 55	Chellappa et al. 2017	Potential gender differences to evening light exposure of 40 lx at 6500 K (blue-enriched) or at 2500 K (non-blue-enriched), and their impact on brightness perception, vigilant attention, and sleep physiology were investigated.	Experimental	In contrast to women, men showed a stronger response to blue-enriched light in the late evening even at very low light levels.
2	Circadian and gender differences after acute high-altitude exposure: Are early acclimation responses improved by blue light?74	Silva et al. 2015	A number of 57 volunteers were randomly assigned to two groups: nocturnal (2200-0230 h) or diurnal (0900-1330 h) and exposed to acute hypoxia (4000 m simulated altitude) in a hypobaric chamber.	Experimental	Some tendencies toward better cognitive performance (d2 attention test) were observed under blue illumination.
3	Light effects on behavioral Performance Depend on the Individual State of Vigilance 64	Correa et al. 2016	Hypothesis was tested by measuring the participants' behavioral state of vigilance before light exposure using the Psychomotor Vigilance Task.	Experimental	Participants with higher levels of basal vigilance before light exposure benefited most from blue-enriched lighting, responded faster in the Sustained Attention to Response Task.
