Association Between Sleep Quality and Oxidative Stress in Postoperative Cardiovascular Patients—A Pilot Study

Journal of Sleep Research, EarlyView.
In 15 postoperative cardiac surgery patients, venous reactive oxygen species (ROS) measured by electron spin resonance (ESR) over 48 h showed no consistent circadian pattern. Higher ROS was associated with lower subjective sleep efficiency and more nocturnal awakenings, but not with other sleep measures.

Lost in the System: Identifying Gaps in Adolescent Insomnia Care Using Nationwide Claims Data and a Healthcare Professional Survey

Journal of Sleep Research, EarlyView.
ABSTRACT Adolescent insomnia is common, persistent and impairing, yet little is known about how and where young people with sleep difficulties are identified and treated in regular care. Recent calls to prioritise sleep health as a public health imperative underscore the need to understand diagnostic and treatment pathways for those affected.

Resynchronisation of the Biological Clock Using Exposure to Low Oxygen Levels in Humans: An Exploratory Study

Journal of Sleep Research, EarlyView.
ABSTRACT Exposure to reduced oxygen levels occurs in several real‐world contexts, such as during air travel or altitude exposure, and emerging evidence suggests that hypoxia may interact with molecular pathways involved in circadian regulation. This exploratory study investigated the effects of normobaric hypoxia on circadian phase shifting in humans ...

A Double‐Blind Randomised Controlled Crossover Trial of the Effect of Blue‐Enriched Ambient Light on Sleep in Older Adults With Sleep Disturbance: The CleverLights Study

Journal of Sleep Research, EarlyView.
ABSTRACT Light interventions have been investigated for treating sleep disturbances in older adults; however, findings are mixed. This proof‐of‐concept trial investigated the effect of blue‐enriched ambient light on electroencephalographic (EEG) sleep in older adults with self‐reported poor sleep.
