Holding Hands Can Sync Brainwaves

Reach for the hand of a loved one in pain and not only will your breathing and heart rate synchronize with theirs, your brain wave patterns will couple up too, according to a study published this week in the Proceedings of the National Academy of Sciences (PNAS). The study, by researchers with the University of Colorado Boulder and University of Haifa, also found that the more empathy a comforting partner feels for a partner in pain, the more their brainwaves fall into sync. And the more those brain waves sync, the more the pain goes away. The study is the latest in a growing body of research exploring a phenomenon known as “interpersonal synchronization,” in which people physiologically mirror the people they are with. It is the first to look at brain wave synchronization in the context of pain, and offers new insight into the role brain-to-brain coupling may play in touch-induced analgesia, or healing touch. The University of Haifa recruited 22 heterosexual couples, age 23 to 32 who had been together for at least one year and put them through several two-minute scenarios as electroencephalography (EEG) caps measured their brainwave activity. Merely being in each other’s presence, with or without touch, was associated with some brain wave synchronicity in the alpha mu band, a wavelength associated with focused attention.
