Is this trial a fit for you?
✓Likely a good fit
Adults 18 years or older admitted to a hospital ward with an expected stay of at least two nights and able to consent.
✕Probably not a fit
Patients with pre-existing sleep disorders or conditions that preclude participation may not benefit from the study.

What this trial studies
This observational study aims to characterize how hospital environmental factors such as air quality, noise, and lighting influence patient sleep. The research will assess real-world ward conditions and their association with sleep quality in admitted patients expected to stay at least two nights. Participants will be adults able to consent and will be observed under standard care without an intervention. The study will help identify environmental contributors to disturbed sleep and inform future mitigation strategies in clinical settings.
Why it matters
Potential benefit: If successful, the study could inform hospital environmental standards to improve patient sleep and recovery.
How similar studies have gone: Previous work has linked environmental factors like noise and light to sleep disruption, but hospital-wide, patient-centered environmental characterization is relatively novel.

Show full inclusion / exclusion criteria
Inclusion Criteria: * Hospital admission with a diagnosis that requires at least 2 nights. * Participant is willing and able to give informed consent for participation in the study. If a patient for example has dementia and/ or the inability to retain information or if they are unable to wear the device, they will not be consented. * Aged 18 years or above. * Able (in the ward staff, research team and investigator's opinion) and willing to comply with all study requirements. Exclusion Criteria: * Any significant disease or disorder which, in the opinion of the investigator, may either put the participants or other patients at risk because of participation in the study, or may influence the result of the study, or the participant's ability to participate in the study. * Reported history of sleep disorders, including obstructive sleep apnoea syndrome (OSAS) or insomnia.
