Content: Purpose
The irregular work schedules of cabin crew with early starts, long working hours, night flights, and the crossing of time zones contribute to circadian stress. The paper investigates the fatigue levels throughout a regular working day and explores the contribution of the type of fight operations (i.e., long haul and medium range crews flights).
A total of 93 cabin crew provided salivary samples for cortisol and melatonin and self-reporting measures of fatigue and mood were collected at the beginning and at the end of a flight duty service.
The two-way mixed-model ANOVA suggest that the type of operation has distinct effects on the neuroendocrine responses and the psychological markers. While similar psychological responses were reported, contrasting effects were found for the physiological responses according to the type of operation considered: The increase in cortisol and melatonin levels in long-range participants’ contrasted with the sharp decrease found in medium range cabin crew.
The chronic exposure to circadian disruption needs to be addressed with a full longitudinal design or a cross-lagged approach that allows for both the continuous assessment of physiological and psychological markers as well as the opportunities for recovery between flights and along continuous rosters.
Research/Practical Implications
In addition to the negative health outcomes associated with irregular working time patterns, the paper also suggests the continuous exposure to artificial environmental light as a contributing factor to the disturbances observed.
The relevance of a multidisciplinary approach to recovery management and circadian stress is highlighted.
