Summary: There is a bidirectional relationship between poor sleep and mood-and anxiety-related disorders, and both are independently associated with altered autonomic nervous system (ANS) function. Heart rate variability (HRV) can reflect ANS dysregulation during sleep, which may play a mediating role in the association between poor sleep and mood-and anxiety-related disorders.

Summary: This study showed that both short and long sleep duration, insomnia symptoms, and IL-6 are associated with suicide risk indicators, with the association between long sleep duration and suicidal ideation possibly mediated by IL-6.

Summary: By analyzing sleep data from two human studies with extended sleep opportunities, it was found that total sleep duration, REM sleep duration, and non-REM sleep duration decreased, while sleep latency increased across nights. It takes multiple nights to reach steady-state values, indicating a multi-day homeostatic sleep process responding to self-selected insufficient sleep duration prior to the study. Once steady-state values were reached, there were large night-to-night variations in total sleep time and other sleep metrics.

Summary: Cognitive behavioural therapy for insomnia (CBT-I) improves total wake time but not total sleep time (TST) for most patients. However, in the 6-12 months following CBT-I, up to 64% of participants experience significant increases in TST. Baseline characteristics such as sleep continuity, mental health, and quality of life are associated with improvements in TST after CBT-I.

Summary: This study aimed to examine the prevalence of insomnia according to DSM-5 criteria and differences in sleep duration across various mental and physical disorders. Results showed that insomnia and short sleep duration are strongly associated with a range of different disorders and conditions, with insomnia being most strongly linked to mental disorders and physical conditions with psychological or psychosomatic properties.

Summary: Based on a cross-sectional survey of 19,926 US adults, the study found that poor sleep quality and extremely long or short sleep durations were associated with an increased risk of COVID-19 infection. Poor sleep quality was also associated with an increased need for hospitalization due to severe COVID-19 illness.

Summary: This study analyzes the sleep of 30,082 individuals across 11 countries using 52 million activity records from wearable devices. It reveals that societal factors explain around 55% of the variation in sleep quality and 63% in sleep quantity. Furthermore, the study finds that exercise plays a key role in improving sleep quality, especially in countries like the U.S. and Finland.

Summary: Evening exposure to blue-depleted light environments has been shown to significantly reduce the fragmentation and microarousals of REM sleep, without affecting the density or latency of REM sleep. This non-circadian effect of BDLE may have therapeutic potential in disorders characterized by fragmented REM sleep.

Summary: This study found that pre-infection sleep quality/duration and insomnia severity are associated with long-term symptoms after COVID-19. Poor sleep quality, severe insomnia, and shorter sleep duration increase the risk of almost every long-term symptom and prolong recovery time. Therefore, promoting good sleep health may help mitigate the COVID-19 sequelae.

Summary: This study analyzed data from 579 menstruating females and found significant associations between short sleep duration, poor sleep quality, and fatigue with heavier bleeding and menstrual cycle irregularity. Long sleep duration and symptoms of insomnia were not found to be related to these outcomes.

Summary: Suboptimal sleep durations and depression frequently cooccur. Short-sleep and long-sleep are commonly thought of as symptoms of depression, but a growing literature suggests that they may be prodromal. Using polygenic scores (PGS), the study investigated the prospective direction involved in suboptimal sleep durations and depression. The results showed that polygenic predisposition to short-sleep was associated with an increased odds of depression onset during an average 8-year follow-up period, while polygenic predisposition to depression was not associated with overall sleep duration, short-sleep, or long-sleep.

Summary: Cognitive-behavioral therapy for insomnia (CBT-I) is recommended as the first-line treatment for insomnia. However, there are differences in therapeutic response between insomnia disorder with short sleep duration (ISS) phenotype and insomnia with normal sleep duration (INS) phenotype. A systematic review identified nine studies comparing the efficacy of CBT-I between ISS and INS phenotypes, and found that CBT-I had a better efficacy for INS phenotype with higher response and remission rates. The therapeutic response of ISS phenotype was significantly different from INS phenotype. Further research is needed to optimize the treatment for insomnia disorder with ISS phenotype.

Summary: Sleeping longer or shorter than recommended is associated with differences in brain structure, indicating potential implications for brain health. Longer sleep duration is associated with various structural differences, while shorter sleep duration is linked to lower cortical surface area.
