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 ...

Motor Sequence Learning Under Sleep Deprivation

Journal of Sleep Research, EarlyView.
ABSTRACT Sleep deprivation (SD) compromises declarative memory encoding and subsequent consolidation, yet its consequences for the acquisition of new motor skill learning remain unknown. Forty‐eight healthy adults underwent either one night of total SD or normal sleep and were tested the next morning using a multimodal approach combining psychomotor ...

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.
