Napping on irregular work schedules increases total sleep time for freight engineers. However, it may slightly reduce the ability to fall asleep, stay asleep, and feel rested.

Area of Science:

  • Occupational Health
  • Sleep Science
  • Transportation Safety

Background:

  • Irregular work schedules pose challenges to sleep health.
  • Limited research exists on napping strategies for professions like freight locomotive engineers.

Purpose of the Study:

  • To investigate the impact of napping on sleep duration and subjective sleep quality in freight engineers with irregular schedules.
  • To assess napping's effect on sleep onset, sleep maintenance, and feeling rested upon awakening.

Main Methods:

  • A 14-day activity log was completed by 179 freight engineers.
  • Data collected included sleep times and subjective sleep evaluations.
  • Statistical analysis examined the relationship between napping and sleep parameters.

Main Results:

  • Napping significantly increased total sleep time but reduced main sleep period duration.
  • Napping was associated with minor increases in difficulty with sleep onset and maintenance.
  • Nap length did not correlate with main sleep time or subjective sleep quality measures.

Conclusions:

  • Napping can be a beneficial strategy for managing sleep in irregular work schedules.
  • Engineers may experience slight trade-offs in sleep initiation and maintenance when napping.
  • Napping's utility depends on individual tolerance for minor sleep disruptions.
