Evidence from multiple reviews confirms that exposure to blue light in the evening suppresses melatonin production, delays circadian timing, and negatively impacts human sleep cycles.
The retrieved literature consistently supports the claim that evening blue light exposure negatively affects human sleep cycles, specifically by inhibiting melatonin secretion and disrupting circadian entrainment through melanopsin-expressing retinal ganglion cells. Papers [0], [6], and [8] explicitly discuss these physiological mechanisms. No papers refute the core claim.
