Blue enriched white light increases levels of alertness, focus, and productivity. Additionally, it suppresses melatonin, which delays the circadian cycle and reduces drowsiness. High levels of blue enriched white lighting during the night time hours have been proven to improve night shift workers’ productivity by shifting circadian entrainment, and by increasing autonomic nervous system activity. This thesis provides a lighting design solution that sustains increases in alertness, productivity, and focus for nocturnists in intensive care facilities, without having a detrimental effect on patients and guests.
