Effects of four conditions (Dim Light‐Placebo, Dim Light‐Caffeine, Bright Light‐Placebo and Bright Light‐Caffeine) on alertness, and performance were studied during the night‐time hours across 45.5 h of sleep deprivation. Caffeine (200 mg) was administered at 20.00 and 02.00 hours and bright‐light exposure (>2000 lux) was from 20.00 to 08.00 hours each night. The three treatment conditions, compared to the Dim Light‐Placebo condition, enhanced night‐time performance. Further, the combined… Expand
