Hospital Environmental Exposure

Recruiting now

Conditions studied: Environment, Sleep, Noise Exposure, Air Quality, Light

In brief

There is an increasing body of evidence that human health is affected by environmental factors such as air quality, noise and light. This applies to both indoor and outdoor environments. While there have been several studies looking at homes, offices and work environments, hospital environments are still poorly characterised. Indoor hospital environments are complex, and patients with various health conditions can spend extended periods of time in wards. A number of studies have reported an association of air pollution exposure and a disturbance to sleep. A lack of sleep, or poor and disrupted sleep can impact health. Disturbed sleep therefore can impact a patient's recovery in hospital wards. In addition to the exposure to air pollutants, noise and light levels within the hospital environment can also have an impact on patient health. Inadequate, or a disrupted light and dark cycles can impact the circadian rhythm of the human body, responsible for the sleep cycle. In this study, the investigators aim to characterise these exposures and address the impact of these exposures on the patient sleep. Given the links between sleep and the environmental conditions.
