Is there any existence of Social touch analgesia for pain relief?
The mechanisms that underlie social touch analgesia are largely not known. Recent research showed hand-holding during pain increases the brain-to-brain coupling network in the central regions of the pain target and the right hemisphere of the pain observer. This increase in network correlates with the magnitude of the pain relief.
The study is the latest in a growing body of research exploring a phenomenon known as "interpersonal synchronization". In this phenomenon, people physiologically mirror the person they accompany. Romantic partners were included in the study as target and observer.
