Can colored light turn down pain? scientists scan brains to find out

NCT ID NCT07245303

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times

Summary

This study investigates how colored light affects pain by scanning the brains of 60 people—half with chronic musculoskeletal pain (like fibromyalgia) and half healthy. Participants will view different light patterns while their brain activity is measured, and some will also receive a pressure pain stimulus. The goal is to understand the brain connections behind light-driven pain relief, not to test a treatment.

What this could mean

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

Active substance
S-cone modulating visual stimulus (colored light)
What this could lead to
If successful, this could reveal how light reduces pain, potentially leading to new non-drug pain relief methods.
What could go wrong
This is an early-stage observational study with only 60 participants, focused on brain mechanisms, not treatment. Results may not lead to a practical therapy.
