  1. Effect of bright light on tolerance to night work.

    Article - En anglais

    Fifteen young (mean age 23.4 years) female nurses engaged in a resuscitation unit and working on a fast rotating shift schedule comprising two consecutive night shifts were exposed to short periods (4x20 min) of bright light (2350 lx) during their night duty to test a possible positive effect on their tolerance to night work.

    Two nights with normal lighting (20-380 lx) and two nights with bright light were compared.

    The following positive effects of bright light upon psychophysical conditions and performance efficiency were noted:

    • in particular, signs of better physical fitness;

    • less tiredness and sleepiness;

    • a more balanced sleep pattern;

    • and higher performance efficiency (letter cancellation test).
