Effects of light and caffeine on human sleepiness and alertness: A simulated driving experiment

Shekari Soleimanloo, Shamsi (2016) Effects of light and caffeine on human sleepiness and alertness: A simulated driving experiment. PhD thesis, Queensland University of Technology.

Abstract

This thesis examined the effects of a novel blue-green light intervention, together with caffeine, on sleepiness and driving performance in young adults, a population that is overrepresented in sleepiness-related road crashes. Light, caffeine, and the combination of light and caffeine each improved alertness after chronic-partial sleep deprivation to a greater extent than did a placebo. Each condition improved subjective sleepiness, objective psychomotor performance, and objective driving performance, with the greatest effect found for light and caffeine in combination. These findings have implications for interventions to reduce mortality and morbidity associated with road crashes.

Impact and interest:

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
