All recruiting trials (5)
-
Light exposure during general anesthesia
This test checks whether covering patients' eyes during general anesthesia changes how much anesthetic adults (18–65) need.
-
Hospital environmental exposures and patient sleep in wards
We’re testing how air quality, noise, and light in hospital wards affect patients’ sleep during their stay.
-
Photodynamic therapy to prevent infections after nasal surgery
This study will test whether a preoperative nasal photodisinfection procedure lowers post‑operative infections and antibiotic use in people having elective nasal or sinus surgery.
-
Optimizing light exposure to prevent and control myopia in children
This study tests if changing classroom lighting to mimic sunlight or using a smartphone app to guide light exposure can help prevent and control myopia in primary school children.
-
Dynamic lighting to improve sleep and circadian rhythm in frail older adults
This test will try dynamic, spectrum-changing hospital room lighting to improve sleep and circadian rhythms for people aged 65 and older during their hospital stay.
