Shift work is an essential aspect of modern society’s 24/7 operations and is particularly indispensable in the medical field. Due to circadian misalignment and reduced sleep during biologically unfavorable hours with shift schedules, shift workers frequently experience insomnia, poor sleep quality, mental health problems and increased cardiovascular risk. Numerous studies have investigated the determinants of shift work tolerance (SWT) in an effort to mitigate sleep-related complaints and reduce comorbidities associated with shift schedules. SWT refers to an individual’s capacity to adapt to shift schedules without experiencing significant negative outcomes [1]. Initially, it was thought to reflect primarily physiological traits and behavioral adaptations, but the concept has since expanded to encompass psychological and social dimensions [1]. SWT is now recognized as a multifaceted phenomenon influenced by a range of factors, including age, sex, trait vulnerability to sleep loss, circadian rhythm, psychological attributes, behavioral and social factors and occupational schedule and demands [2].
