What This Trial Is About
Researchers are investigating how environmental factors such as air quality, noise, and light inside hospital wards affect patient sleep and health. The study focuses on hospital environments, which are complex and where patients may stay for extended periods. Poor or disrupted sleep can negatively impact recovery, and environmental disturbances like noise and irregular light cycles may disrupt patients' circadian rhythms and sleep quality. The study uses sound level meters, air quality sensors, and light meters placed in hospital wards to measure environmental conditions like nitrogen dioxide, ozone, particulate matter, noise volume, and light levels. Patients admitted for at least two nights will wear two monitors: an actigraphy device to track sleep patterns and a second device to measure heart rate and body temperature. Data from these devices will be compared to environmental measurements to assess links between hospital conditions and sleep. Participants will keep a sleep diary during their hospital stay, noting sleep times, awakenings, and any disturbances from light or noise. The study will record sleep duration, efficiency, latency, and awakenings for up to seven days or until discharge or ward transfer. Environmental data collection will continue for about one and a half years, while patient monitoring focuses on their time in the hospital. The goal is to understand environmental impacts on sleep and suggest improvements for hospital settings to support patient recovery.

Your Study Journey
Screening
Duration: 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
1 visit (in-person)
Monitoring
Duration: Up to 7 days or until discharge or ward transfer, whichever is first
Participants who are admitted to the hospital ward are observed for environmental exposures such as air quality, noise, and light levels. Their sleep patterns and vital signs are monitored using wearable activity and heart rate monitors, and participants complete a daily sleep diary.
Daily visits for up to 7 days
Long-term Monitoring
Duration: Approximately 1 year and 6 months to 1 year and 11 months
Environmental conditions in hospital wards are continuously measured over an extended period to assess air quality, noise, temperature, and light levels.
Continuous environmental monitoring without participant visits
