Rooftop ICU gardens and light sensors tackle delirium through daylight exposure
Start here
King's College Hospital has converted a rooftop, funded by charity, so patients from 60 intensive care beds can go outdoors while on full life support. The aim is to ease ICU delirium and hallucinations, which are linked to disrupted circadian rhythms — the lack of a bright-day, dark-night cycle. A similar garden at George Hospital, set up by the John King Brain Tumor Foundation, serves stroke and neurosurgery patients. Clinical observations cited in a MedCram review suggest adequate daylight can cut ICU stays by roughly 30%, and in a COVID study, 15 minutes of daily light for 7 days shortened stays. A wearable MiEye sensor records light exposure and pairs it with sleep diaries to model circadian phase and amplitude, pointing toward measurable circadian tracking as part of the approach.
