Title: Illuminating Confounds: Why Light‐Based Sleep Disruption Methods Need Reconsideration.
Authors: Norman, Helena1 (AUTHOR) h.norman.1@research.gla.ac.uk, Killen, Shaun S.1 (AUTHOR)
Source: Journal of Sleep Research. Aug2025, p1. 4p.
Subject Terms: *CONFOUNDING variables, *CIRCADIAN rhythms, *RESEARCH protocols, *COGNITION, *SLEEP deprivation, *SLEEP interruptions
Abstract: The article discusses the methodological concerns surrounding light-based sleep disruption studies in animal research, particularly in relation to cognitive functions in non-mammalian species. It highlights that while light exposure is commonly used to disrupt sleep, it also acts as a significant confounding variable that can influence endocrine functions and circadian rhythms, potentially skewing results related to sleep deprivation. The authors suggest that future research should incorporate diverse sleep disruption methods, physiological controls, and non-invasive techniques to better isolate the effects of sleep loss from other physiological changes, thereby enhancing the ecological relevance and interpretability of findings in sleep research.
