Amplitude measures for melatonin (Mel), cortisol (Cort), core body temperature (Temp), alertness (Alert) and performance (Perf) on D2 and the CR separately for the moderate light and bright light treatment group. Melatonin height: pmol/L; Melatonin area under the curve (AUC) nmol/L*min; Melatonin width: h:min. Cortisol measures are in µg/dL, temperature measures in degrees Celsius, Alertness in mm and Performance in number of additions attempted.
