Light Exposure and Melatonin Secretion in Shiftworkers

  • Marie Dumont

Abstract

There are many work schedules which affect workers’ sleep-wake cycle. In the present paper, shiftwork will refer essentially to nightwork, including both permanent nightwork and rotating night/day work. The difficulties experienced by shiftworkers are multi-facetted and vary with the type of schedule, type of work (physical and mental workload), familial situation, age, health status, etc. Nevertheless, it has been consistently reported that sleep difficulties and fatigue are the main complaints of shiftworkers 1-3.
