Bright light, better mood? glasses that mimic morning sun tested for depression on dialysis
NCT ID NCT07729358
First seen Jul 27, 2026 · Last updated Aug 18, 2026 · Updated 3 times
Summary
This trial tests whether light therapy glasses can reduce depression in people with end-stage kidney disease who undergo hemodialysis three times a week. Participants wear either active glasses (1000 lux) or a sham device (50 lux) for 30 minutes each session over five weeks. The goal is to see if morning light exposure improves mood and sleep quality without medication.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- light therapy using active glasses (Luminette3) emitting 1000 lux
- What this could lead to
- If effective, light therapy could offer a drug-free way to ease depression and improve sleep in people undergoing kidney dialysis.
- What could go wrong
- This is a relatively small, early-stage trial. The sham device also emits some light (50 lux), which may reduce the difference between groups. Light therapy may not work for everyone and requires consistent use.
