Blue and Near-Infrared light tested as a way to boost circulation
NCT ID NCT07338695
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing whether shining blue or near-infrared light on the hands can change blood flow in tiny blood vessels. Forty healthy adults will each attend two sessions, one for each light type. Researchers will use special cameras and laser devices to measure blood flow and skin temperature before, during, and after the light treatment.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Photobiomodulation (blue and near-infrared light)
- What this could lead to
- If it works, this could point toward a non-invasive way to improve blood flow in conditions like Raynaud's or poor circulation.
- What could go wrong
- This is a very early, small study in healthy people, not patients. It only looks at immediate effects, not long-term benefits or safety.
