The chronobiologic-based practical approach to shift work

초록

Shift work can have a short-term, long-term adverse effect on health because it is exposed to situations that constantly disturb the circadian rhythm of the human. The purpose of this review was to examine the critical principles of determining health management plans for shift workers. Practical principles for maintaining a healthy shift work lifestyle include: Maintaining circadian stability, maintaining a predictable work schedule, minimizing night shifts, and ensuring equality of working conditions. Melatonin and light therapy can be used effectively for shift work as a chronotherapeutic method. Proper caffeine intake, sleeping pills, naps, and planned meal schedules also could be a method for managing the circadian rhythm of shift workers in social life. Additionally, efforts should be made to maintain a positive work-life balance, in which work environment, workloads, overall safety, family, and social relationships are all considered. With training and basic knowledge of circadian rhythms, employers and shift workers can boost the company's profits, reduce social losses, and maintain a healthy lifestyle. © 2019 Korean Academy of Sleep Medicine.
