Summary: The study aimed to examine the effect of sleep timing intervention on sleep quality, attention, and sleepiness at work among night shift workers with shift work disorder. The results showed that participants had longer sleep duration, higher sleep quality, shorter reaction times, and fewer lapses during evening sleep schedules compared to morning sleep schedules. The differences between sleep schedules were most prominent among those with late chronotypes.

Summary: One in five workers today engaged in shift work face mental and physical health risks, but recovering efficiently through interventions can mitigate these effects, improve work-life balance, and enhance overall well-being.

Summary: The study revealed that shift work has a greater impact on periodontal disease than sleep duration. Shift workers are at higher risk of periodontal disease, especially when they have shorter or longer sleep durations.

Summary: This study aimed to provide and evaluate a management coaching program for shift workers, focusing on sleep education and individualized behavioral strategies. The results showed that the intervention did not reduce sick leave compared to the control group, but improvements were seen in sleep hygiene, insomnia, depression, and anxiety severity for both groups.

Summary: Sleep is a crucial biological process for maintaining homeostasis and key functions in animals. Dysfunctional sleep can lead to negative effects on health and cognition. Cannabinoids have been found to play a role in sleep modulation, with cannabinoid receptors being involved in sleep promotion. The alteration of cannabinoid receptors could potentially be used in treating sleep disorders.

Summary: This article reviews the relationship between circadian rhythm disturbance and kidney stone disease (KSD), summarizing the risk factors and treatment methods. The results indicate that KSD is associated with systemic disorders such as metabolic syndrome, inflammatory bowel disease, and microbiome dysbiosis, and some chronotherapies have been proven effective.

Summary: Night shift work is associated with differential methylation in core circadian genes, including CSNK1E, NR1D1, and ARNTL. Night shift workers may exhibit different methylation levels in specific gene regions.

Summary: This study conducted remote monitoring of circadian and sleep cycles to identify differences in health risks between nightshift workers and dayshift workers. Nightshift workers had poorer rest-activity rhythm index and rest quality, and a lower occurrence of circadian periods compared to dayshift workers. Factors such as years of night work exposure, shift type, age, and chronotype were associated with poor rest-activity rhythm index and rest quality.

Summary: Cortisol, the end product of the HPA axis, is mainly increased in stressful situations or chronic disorders. Hair cortisol has emerged as a promising biomarker for long-term retrospective HPA activation, closely related to neuropsychiatric disorders, with experimental approaches and findings from scientific literature contributing to existing data on cortisol concentrations in patients with sleep disorders.

Summary: Railway workers with irregular work schedules are at a higher risk of circadian rhythm sleep-wake disorders (CRSWDs), which may lead to dyslipidemia. A cross-sectional study in Southwest China found that shift work sleep disorder (SWD) and advanced sleep-wake phase disorder (ASWPD) were associated with a higher risk of dyslipidemia in railway workers. The SWD group had elevated total cholesterol, triglycerides, and low-density lipoprotein levels, while the ASWPD group had elevated total cholesterol and low-density lipoprotein levels.

Summary: This study explored the mediating effect of circadian rhythm amplitude and stability between work stress and sleep quality among Chinese shift-working nurses. The results showed that work stress can directly and indirectly affect sleep quality through circadian rhythm, with the indirect effects accounting for 36.7% of the total effect. The study highlights the common issue of poor sleep quality among shift-working nurses and suggests the importance of improving both work stress and circadian rhythm for better sleep quality.

Summary: The present study evaluates the effect of exogenous melatonin on sleep and circadian parameters in patients with bipolar disorder and delayed sleep-wake phase disorder. Results indicate that personalized treatment with exogenous melatonin can modify self-reported chronotype, sleep onset time, and sleep efficiency and duration in patients with comorbid bipolar disorder and delayed sleep-wake phase disorder, suggesting potential efficacy in improving sleep patterns in this population.

Summary: The study explored the association between cortisol rhythm trends and shift work regularity in midwives. Results showed a circadian rhythm in cortisol secretion among midwives, with slightly lower fluctuation range in those with irregular shift patterns. Shift work regularity significantly impacted cortisol levels independent of total working hours per week.
