Bright light, better nights: new hope for veterans with TBI
NCT ID NCT03785600
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested whether sitting in front of a bright lightbox for an hour each morning could improve sleep, reduce pain, and boost quality of life in 77 veterans with chronic mild traumatic brain injury (mTBI). Participants used either a lightbox or a negative ion generator (placebo) for 60 minutes within 90 minutes of waking. The goal was to see if better sleep could help veterans recover more fully from their injuries.

Morning bright light therapy (lightbox)
What this could lead to
If effective, this could offer a simple, low-cost way to improve sleep and reduce pain in veterans with TBI, helping them recover better.
What could go wrong
This was a small, completed trial with only 77 participants, so results may not apply to all veterans. Light therapy may not work for everyone and can cause eye strain or headache.
