Blind people feel better than people who see their own heartbeat. This was reported by the press service of the Karolinska Institute.
To find out, thirty-six blind and sighted people were asked to count their own heartbeats without checking their pulses or touching their bodies. At the same time, the researchers recorded the participants’ actual heartbeats using a pulse oximeter. They then compared the data with the recorded data to assess the extent to which the participants were able to sense their own heartbeat.
Analysis showedthat the blind participants perceived the heartbeat better than the participants who saw it. The average accuracy of the blind group was 0.78, while the average accuracy of the seeing groups was 0.63; where 1.0 is 100 percent accuracy.
“This gives us important information about brain plasticity and how a loss of one sense can improve another, in this case the ability to sense what’s going on in your own body,” the authors summarize.
This leads scientists to believe that blindness improves the ability to perceive signals from the body.
