Health effects of shift work

J LaDou

    The Western Journal of Medicine
    |December 1, 1982
    PubMed
    Summary

    Shift work affects millions, disrupting natural circadian rhythms and causing health issues like poor sleep and worsened chronic conditions. Careful worker selection and regular check-ups can mitigate these negative effects.

    Area of Science:

    • Occupational Health
    • Chronobiology

    Background:

    • Millions of American workers engage in shift work, with some industries exceeding 50% participation.
    • The growing prevalence of alternative work schedules raises concerns about worker well-being and family life.
    • Approximately 20% of workers find shift work intolerable due to physiological challenges.

    Purpose of the Study:

    • To highlight the health implications of shift work and circadian desynchronization.
    • To explore strategies for mitigating the adverse effects of non-traditional work schedules.

    Main Methods:

    • The study reviews existing data on shift work prevalence and its physiological impact.
    • It discusses the concept of circadian rhythms and their role in worker health.
    • Analysis of health effects associated with circadian desynchronization is presented.

    Main Results:

    • Shift work disrupts circadian rhythms, leading to issues with sleep, gastrointestinal function, and other organ systems.
    • Existing health conditions like diabetes, epilepsy, and thyrotoxicosis can be aggravated by circadian desynchronization.
    • Individual tolerance to shift work varies, with some workers experiencing significant adverse effects.

    Conclusions:

    • Worker selection is a viable strategy to reduce health problems associated with shift work.
    • Periodic medical examinations for shift workers are recommended to monitor and manage health risks.
    • Addressing circadian desynchronization is crucial for the health and well-being of the shift work population.
