Tired, strained, and hurt: The indirect effect of negative affect on the relationship between poor quality sleep and work injuries

Exploring Clinical Trials to Manage Firefighters' Sleep Quality: A PRISMA Compliant Systematic Review

Sleep research has grown over the past decades and investigators are deeply involved in studying sleep and its impact on human health and body regulation. Despite the understanding that insufficient sleep is strongly linked to the development of several disorders, unsatisfactory sleep exposes health and safety to innumerous risks. The present study aims to review and analyze the main results of clinical trials, registered at ClinicalTrials.gov and ICTRT databases, and developed construct strategies to improve sleep quality on firefighters and enhance professionals' sleep and health conditions. The protocol was registered in PROSPERO under number CRD42022334719. Trials registered between first registry and 2022 were included. We retrieved 11 registered clinical trials; seven met eligibility criteria and were included in the review. A relation between sleep disorders, shift work, and occupational health problems was found, and retrieved trials showed that sleep education programs can improve sleep quality and sleep hygiene. Science has already recognized sleep's importance for metabolic functioning and survivorship. Nevertheless, it continues to play a major role in discovering methods to diminish the problems faced. Strategies contemplating sleep education, or intervention, should be presented to fire services to tackle this problem and promote healthier and safer environments.

Supervisor expectations regarding work-related messages: their differential effects among remote and on-site workers

Purpose

Research suggests that supervisor expectations regarding the need to respond quickly to work-related messages (SE) tend to be positively related to employees' levels of emotional exhaustion. In the present research paper, the authors examine the indirect – through emotional exhaustion – effects of these expectations on employees' levels of family satisfaction, life satisfaction and sleep quality. They also explore whether and how these associations differ between employees working on-site (n = 158) or remotely (n = 284).

Design/methodology/approach

A total of 442 employees completed an online survey that covered measures on SE, emotional exhaustion, family and life satisfaction and sleep quality.

Findings

As hypothesized, the results of the study revealed that the indirect effects of SE on family satisfaction, life satisfaction and sleep quality were significantly mediated by emotional exhaustion. Finally, the relations between SE and the mediator (emotional exhaustion) were stronger among employees working on-site than among employees working remotely.

Practical implications

SE prevention could be encouraged to decrease employees' emotional exhaustion, in turn increasing their sleep quality, family satisfaction and life satisfaction.

Originality/value

These results revealed that working remotely helped buffer the undesirable effects of SE on emotional exhaustion.
