Night‐time bright light (BL) treatment and triazolam (0.125 mg/day) were given to three healthy elderly people in a cross‐over design. They kept a daytime sleepiness test and a sleep log, and their wrist‐activity was monitored simultaneously. Subjectively, BL increased daytime sleepiness and naps, and decreased night‐time sleep. Triazolam decreased daytime sleepiness and naps, and increased night‐time sleep. Actigraphic night‐time sleep and naps on the first day were similar to these results. However, on the fourth day night‐time insomnia induced by BL had recovered, and naps were shorter than the baseline. Triazolam increased actigraphic naps as the days passed.
