Light therapy tested to calm confused ICU patients
NCT ID NCT05807178
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether dynamic light therapy can restore natural sleep-wake cycles in intensive care patients suffering from delirium. Forty adults in the ICU will receive either a special light algorithm or standard hospital lighting. Researchers will measure changes in melatonin, clock genes, and other markers to see if the light helps reset their internal body clocks.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Dynamic light therapy device
- What this could lead to
- If it works, this could offer a simple, drug-free way to reduce delirium and improve recovery in ICU patients.
- What could go wrong
- This is a very small early-stage trial with only 40 participants, so results may not apply broadly. The effect of light on delirium is still uncertain.
