Light on the neck and nose may calm stress, early study hints
NCT ID NCT07475858
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether shining red/near-infrared light on the neck and inside the nose (called photobiomodulation) can improve how the body handles stress. Forty healthy adults will undergo a stressful test while wearing either a real or sham light device. Researchers will measure heart rate variability and other signs of nervous system activity to see if the light therapy makes a difference.
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 (photobiomodulation) via a device placed on the neck and inside the nose
What this could lead to
If it works, this could point toward a non-drug way to help people manage stress by calming the nervous system.
What could go wrong
This is a very small, early study in healthy people, not patients. It only measures short-term changes, so it may not lead to any real-world treatment.
