“…A meta-analysis done by Zhu et al that examined phototherapy’s effect on cognition problems indicated that phototherapy interventions used on subjects with dementia were useful in improving attention, executive function, and working memory 34 . Using the NHANES data set, Shi and Chen investigated the relationship between ambient light (as calculated from an actigraph device) and cognitive impairment, and found that an increase in ambient light was associated with a decrease in cognitive impairment 35 . Clinically, the findings from our study and others suggest that interventions that focus on improving the alignment between dark-light exposure and rest-activity may be beneficial to cognitive health, a hypothesis that warrants further investigation in future studies.…”

Proper alignment of activity-rest and light–dark patterns allows for healthy bodily functions to occur at optimal times of the day. Disruptions to this alignment may cause poor sleep as well as physical, mental, and cognitive problems. The purpose of this cross-sectional study was to determine if poorer circadian alignment was associated with decreased cognitive functioning among older (> 60 years) participants in the National Health and Nutrition Examination Survey. We utilized actigraphy-based rest-activity and dark-light measurements to calculate phasor magnitude (strength of circadian alignment coupling) and phasor angle (phase difference between activity-rest and light–dark cycles). Multiple linear regression models were used to determine associations of phasor magnitude and angle with performance in various cognitive tests, including Digit Symbol Substitution Test score (DSSS), CERAD Savings Percentage (CSP), and Animal Fluency Test (AFT) score. The results showed that a lower phasor magnitude (which indicates decreased strength of alignment coupling between rest-activity and dark–light cycles) was significantly associated with decreased DSSS (indicating slower processing speed and poorer working memory) when controlling for many important sociodemographic factors. However, this association became non-significant when accounting for sleep duration and total physical activity. Phasor angle did not have a significant association with any of the cognitive scores. Overall, we provided evidence indicating that circadian alignment may be a predictor of cognitive performance. Future studies should investigate whether improving circadian alignment may improve cognitive function and prevent cognitive decline.

Background Certain studies have indicated a link between obstructive sleep apnea and insulin resistance in specific populations. To gain more clarity, extensive research involving a broad sample of the overall population is essential. The primary objective of this study was to investigate this correlation by utilizing data from the National Health and Nutrition Examination Survey database. Methods The analysis incorporated data from the National Health and Nutrition Examination Survey database spanning the time periods from 2005 to 2008 and from 2015 to 2018, with a focus on American adults aged 18 years and older after applying weight adjustments. Key variables such as obstructive sleep apnea, triglyceride glucose index, and various confounding factors were considered. A generalized linear logistic regression model was used to investigate the association between obstructive sleep apnea and the triglyceride glucose index, with additional exploration of the consistency of the results through hierarchical analysis and other techniques. Results The study included participants aged between 18 and 90 years, with an average age of 46.75 years. Among the total sample, 50.76% were male. The triglyceride glucose index demonstrated a diagnostic capability for obstructive sleep apnea, with an AUC of 0.701 (95% CI: 0.6619–0.688). According to the fully adjusted model, individuals in the fourth quartile of the triglyceride glucose index showed an increased likelihood of having obstructive sleep apnea compared to those in the first quartile (OR: 1.45; 95% CI: 1.02–2.06; P < 0.05). Subgroup analysis indicated that male sex (OR: 2.09; 95% CI: 1.76–2.45; P < 0.05), younger age (OR: 2.83; 95% CI: 2.02–3.96; P < 0.05), white ethnicity (OR: 2.29; 95% CI: 1.93–2.73; P < 0.05), and obesity (OR: 1.54; 95% CI: 1.28–1.85; P < 0.05) were correlated with an elevated risk of OSA. Conclusions This study demonstrated a strong association between an elevated TG index and OSA. Additionally, the triglyceride glucose index could serve as an independent predictor of obstructive sleep apnea.

We evaluated the relationship between sleep factors and tinnitus risk using data from the US National Health and Nutrition Examination Survey (2007–2012), focusing on adults aged 20 to 80 years. Our analysis included 4354 participants, with sleep patterns categorized as healthy, intermediate, or poor. We observed that both short (odds ratio [OR]: 1.43) and long (OR: 1.48) sleep durations increased the risk of tinnitus compared with the healthy range (7–9 hours). Additionally, sleep disturbances were significantly correlated with tinnitus (OR: 1.52), with the strongest association occurring in individuals with poor sleep patterns (OR: 1.71). The results of the weighted logistic regression analysis underscored these findings.
