Blind people have a heightened ability to feel signals from their body, specifically their own heartbeat, according to a study by researchers at Karolinska Institutet in Sweden and Jagiellonian University in Poland. The study involved 36 blind participants and 36 sighted participants who were asked to count their own heartbeats. The blind participants had an average accuracy rate of 0.78, compared to the sighted group’s 0.63. This ability to sense heartbeats may provide an advantage when it comes to emotional processing, as heart signals and emotions are closely linked. The research group plans to study how blind individuals perceive their own bodies and if structural changes in the brain may explain their increased ability to sense signals from the inside of the body.
