Nonpharmacologic delirium prevention relies on environmental and activity-based strategies to support sleep, circadian rhythm, and mobility. Sleep optimization improves sleep without medications, daylight exposure helps synchronize the internal clock, and early mobility maintains function and reduces delirium risk. Benzodiazepine use for sleep is a pharmacologic approach and is associated with increased delirium risk in hospitalized patients, so it is not a nonpharmacologic measure.
