Bright light exposure reduces negative affect and modulates EEG activity in sleep-deprived and well-rested adolescents

IntroductionThis study investigated whether a single morning session of bright light exposure modulates alertness, cognition, mood, and EEG activity in well-rested and partially sleep-deprived adolescents.MethodsForty-seven subjects (15-21 years) were assigned to a well-rested (8 h sleep; 9 men, 15 women) or a sleep-deprived group (4 h sleep; 11 men, 12 women).
