Sleep science
Environmental effects on sleep initiation, continuity, architecture and recovery
family: Core
ND-0012 · 2018 · Review
A review of the environmental parameters necessary for an optimal sleep environment
Authors per journal record. Building and Environment
Noise, temperature, light and air quality each have plausible and documented effects on sleep quality and continuity.
ND-0013 · 2012 · Review
Effects of thermal environment on sleep and circadian rhythm
Okamoto-Mizuno & Mizuno. Journal of Physiological Anthropology
Heat and cold exposures can increase wakefulness and reduce REM or slow-wave sleep, with thermoregulation tightly coupled to sleep.
ND-0014 · 2017 · Review
Thermal environment and sleep quality: A review
Lan, Tsuzuki, Liu & Lian. Energy and Buildings
Moderate heat or cold can reduce sleep quality; control of the bed micro-environment may offer a lower-energy route to comfort.
ND-0015 · 2024 · Review
Optimizing bedroom thermal environment: A review of human body temperature, sleeping thermal comfort and sleep quality
Authors per journal record. Energy and Built Environment
Body-temperature distribution provides a useful bridge between thermal comfort and sleep quality, which are related but not interchangeable.
ND-0016 · 2025 · Review
How do we create a healthier thermal environment for sleep? A review of sleep thermal comfort and sleep quality
Authors per journal record. Building and Environment
Thermal needs vary between and within people; pre-sleep adjustment alone may not meet overnight sleep and comfort needs.
ND-0017 · 2026 · Experimental study
Multimodal evidence of temperature and sex effects on sleep: sleep physiology, sleep quality, and next-day performance
Authors per journal record. Building and Environment
Warmer nights reduced sleep continuity and efficiency; autonomic and next-day outcomes differed across temperatures and by sex.
ND-0018 · 2025 · Narrative review
Dreamy Dwellings: How the Sleep Environment Affects Sleep Health in Adults
Gregory D. M. Potter. Lifestyle Medicine
Reviews multiple environmental inputs that can alter sleep, including sensory, thermal and social factors.
ND-0037 · 2019 · Review
Effects of light on human circadian rhythms, sleep and mood
Blume, Garbazza & Spitschan. Somnologie
Light timing, spectrum and intensity can alter circadian rhythms, sleep and mood through retinal pathways beyond image-forming vision.
ND-0038 · 2014 · Case-control pilot study
Impact of Windows and Daylight Exposure on Overall Health and Sleep Quality of Office Workers
Boubekri et al. Journal of Clinical Sleep Medicine
Workers with more window/daylight exposure reported better sleep and wellbeing and had longer sleep duration in actigraphy analyses.
ND-0040 · 2026 · Descriptive field study
Sleep and light ecologies of parents with young infants: descriptive findings from the SUNSHINE project
Authors per journal record. npj Biological Timing and Sleep
Documents real-world light and sleep patterns in a population with fragmented sleep and distinctive household routines.
ND-0078 · 2007 · Literature review
Do patients in hospitals benefit from single rooms? A literature review
Authors per journal record. Health Policy
Single rooms showed moderate benefits for satisfaction, sleep/noise and privacy/dignity; infection evidence was conflicting and recovery evidence limited.
ND-0079 · 2018 · Systematic review
Single-Occupancy Patient Rooms: A Systematic Review of the Literature Since 2006
Taylor, Card & Piatkowski. HERD
Most studies reported at least some advantages of single rooms, with stronger evidence for communication, infection control, noise/sleep and preference, but trade-offs remained.
ND-0080 · 2023 · Systematic review and narrative synthesis
Clinical, humanistic and economic outcomes associated with single rooms compared with shared accommodation for acute hospital admissions
Authors per BMJ Open record. BMJ Open
Patients often preferred single rooms for privacy and shared rooms for social interaction; sleep perceptions often favored single rooms while objective noise differences were less consistent.
ND-0093 · 2025 · Experimental neuroscience study
Norepinephrine-mediated slow vasomotion drives glymphatic clearance during sleep
Hauglund et al. Cell
Synchronized norepinephrine and vascular oscillations were linked to glymphatic CSF flow during NREM sleep; zolpidem dampened key dynamics.
ND-0094 · 2026 · Randomized crossover human study
The glymphatic system clears amyloid beta and tau from brain to plasma in humans
Dagum et al. Nature Communications
Normal sleep was associated with morning plasma biomarker patterns consistent with greater glymphatic clearance of amyloid beta and tau than sleep deprivation.
ND-0095 · 2012 · Foundational animal study
A Paravascular Pathway Facilitates CSF Flow Through the Brain Parenchyma and the Clearance of Interstitial Solutes, Including Amyloid beta
Iliff et al. Science Translational Medicine
Established a paravascular pathway supporting exchange of CSF with interstitial fluid and clearance of solutes.
ND-0102 · 2018 · Guideline
Environmental noise guidelines for the European Region
World Health Organization. World Health Organization
Provides health-based recommendations for environmental-noise exposures, including night-time impacts on sleep.
