AI Article Synopsis
- Job demands can affect how well people sleep, but it's not clear how different levels of these demands impact sleep.
- A study looked at over 2,900 workers to find out how job pressures relate to various sleep issues, like feeling tired or not sleeping well.
- Results showed that having a moderate amount of job demands leads to better sleep, while too low or too high demands can make sleep worse, especially for people who don’t have much control at work.
Article Abstract
Objectives: It has been reported that job demands affect sleep, but how different levels of job demands affect sleep remains unclear. We examined whether curvilinear relationships exist between job demands and multiple sleep health outcomes.
Design: Cross-sectional analyses with linear and quadratic effects, using self-administered survey data.
Setting: A national sample of US adults.
Participants: Workers from Midlife in the United States Study (MIDUS2; n = 2927).
Measurements: The Job Content Questionnaire assessed overall and 5 specific aspects of job demands (intensity, role conflict, work overload, time pressure, and interruptions). Habitual sleep health patterns across 5 dimensions (regularity, satisfaction/quality, daytime alertness, efficiency, and duration) were assessed. Age, sex, race/ethnicity, marital/partnered status, education, job tenure, work hours, body mass index, smoking status, and study sample were covariates.
Results: There were significant linear and quadratic relationships between job demands and sleep outcomes. Specifically, the linear effects indicated that participants with higher job demands had worse sleep health, such as shorter duration, greater irregularity, greater inefficiency, and more sleep dissatisfaction. The quadratic effects, however, indicated that sleep regularity and efficiency outcomes were the best when participants' job demands were moderate rather than too low or too high. These effects were found for overall job demands as well as for specific aspects of job demands. Stratified analyses further revealed that these curvilinear associations were mainly driven by participants with low job control.
Conclusions: Moderate levels of job demands, especially if combined with adequate job control, are related to optimal sleep health.

In modern society, many workers struggle with sleep deprivation due to their work schedules and excessive workloads. Accurate self-awareness and self-monitoring abilities are crucial for workers to adopt risk-coping strategies and protective behaviors when fatigued. The current study examined the relationship between chronotypes and self-monitoring performance during 24 h of sleep deprivation.

Background And Aim: (CM) and (AM) are medicinal mushrooms with potential applications in the treatment of mood disorders, including depression and anxiety. While research suggests that both CM and AM possess anti-inflammatory properties and hold potential for treating depression when administered separately, there is limited knowledge about their efficacy when combined in a formula, as well as the underlying mechanism involving the modulation of microglia.
