People who feel lonely show altered brain activity when processing internal physical signals
A recent study indicates that loneliness alters how we perceive internal physical signals. Lonely individuals tend to distrust their bodily sensations and show reduced brain responses to their heartbeats, offering a physiological explanation for the distress of isolation.
A recent study published in Biological Psychology suggests that loneliness is linked to altered brain activity when processing internal physical signals, such as heartbeats. The research, conducted by Kentaro Ono, an assistant professor at the Center for Brain, Mind, and KANSEI Sciences Research at Hiroshima University, indicates that individuals who report higher levels of loneliness show reduced brain activity related to monitoring their heartbeats.
This physiological perspective on loneliness aligns with the hypervigilance model, which posits that lonely individuals are more sensitive to social rejection and stress, leading to heightened emotional distress. The study's findings could provide valuable insights into the underlying mechanisms of loneliness and its connection to psychiatric disorders, highlighting the importance of interoception—the perception of internal bodily states—in emotion regulation.
