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.
