Love hurts, at least according to many a romantic songwriter, but it may also help ease pain, US scientists suggest.
Brain scans suggest many of the areas normally involved in pain response are also activated by amorous thoughts.
Stanford University researchers gave 15 students mild doses of pain, while checking if they were distracted by gazing at photos of their beloved.
The study focused on people early in a romance, journal PLoS One reported, so the "drug of love" may wear off.
The scientists who carried out the experiment used "functional magnetic resonance imaging" (fMRI) to measure activity in real-time in different parts of the brain.
