Summary

This study tests two simple, drug-free ways to improve sleep for adults in the intensive care unit: playing pink-brown noise to mask hospital sounds, or a quiet time protocol with earplugs and eye masks. Researchers will track sleep using a wrist-worn smartwatch in 18 patients. The goal is to see if these low-cost approaches can help ICU patients get better rest and support recovery.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: pink-brown noise masking and quiet time protocol (behavioural interventions)
What this could lead to: If it works, this could point toward simple, drug-free ways to help ICU patients sleep better and recover faster.
What could go wrong: This is a very small, early trial with only 18 participants, so results may not apply to all ICU patients. The interventions are non-invasive but may not improve sleep for everyone.
