Título Circadian rhythms and behaviour of permanent nightworkers.
Información bibliográfica Aug. 1979, Vol.44, No.1, p.1-11. 25 ref.
Resumen Study of rest/activity rhythms of 13 rotary printers on permanent nightshift (average experience 15.5 years). They reported during 1 week the hours of their sleep onset and of their meals, and their subjective appreciation of tiredness and mood. The average sleep duration (7.84h) can be compared with that of day workers and is fairly longer than the duration of day sleep of shiftworkers when they are on nightshift. This long sleep can be attributed to the early bedtime (around 05.00h) and an adjustment of biological rhythms to the schedule inversion. Other evidence (naps, meal time) supports the hypothesis of a physiological adjustment. The fragility of this adjustment is underlined.
