Current sleep interventions for shift workers: a mini review to shape a new preventative, multicomponent sleep management programme

Introduction: Shift work can lead to sleep disturbances and insomnia during the sleeping period, as well as excessive sleepiness and fatigue during the waking period. While Cognitive Behavioral Therapy (CBT-i) is recommended as the first line of treatment for insomnia, key elements of CBT-i, such as maintaining a consistent sleep schedule, can be challenging for shift workers, highlighting the need for tailored sleep interventions. This mini review provides a narrative synthesis of non-pharmacological sleep interventions for shift workers and informs the development of a preventative, multicomponent sleep management programme. Method: An informal review was conducted in line with Phase 1 of the Framework for the Development and Evaluation of Complex Interventions. Results: A variety of strategies have been employed to help manage the impacts of shift work on sleep, including: CBT-i, adjusting shift schedules, controlled light exposure, sleep hygiene education, planned napping, caffeine consumption, and mind-body interventions (e.g., yogic relaxation). Discussion: Recommendations, limitations, and directions for future research are discussed; notably, the role of the family, the commute to and from the workplace, and the eating behaviors of employees appear to have been overlooked in current intervention efforts. Digital CBT-i platforms could help to provide an effective, scalable, and low-cost method of reducing insomnia in shift workers.
