Light on the wrist: a new way to tame high blood pressure?
NCT ID NCT07525310
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether shining a specific red laser light on the wrist (over the radial artery) can improve blood pressure and blood vessel function in people with hypertension who are already taking the medication losartan. Eighty adults will be randomly assigned to receive either the active light therapy or a sham (fake) treatment twice a week for four weeks. The goal is to see if this painless, non-invasive approach can offer additional cardiovascular benefits beyond standard medication.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
red laser light therapy (photobiomodulation) applied over the radial artery
What this could lead to
If it works, this could offer a non-drug, side-effect-free way to help control blood pressure and improve blood vessel health in people already on medication.
What could go wrong
This is a small, early-stage trial with only 80 people, so results may not apply to everyone. The effect may be too small to matter, or the sham group might show similar improvements.
