Exercise plus brain zaps: a new anxiety fix?
NCT ID NCT06874595
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether combining physical activity with a gentle brain stimulation technique (HD-tDCS) can lower anxiety more than either alone. Researchers will measure anxiety levels and brain blood flow in 29 healthy adults aged 18-50. The goal is to understand how these two approaches might work together to calm the mind.
