Scientists decided to test the famous claim that the hearts of lovers supposedly beat in unison.
To confirm or deny this statement, scientists conducted studies involving almost 200 people.
Researchers at the Hebrew University of Jerusalem have investigated whether a romantic relationship can make the hearts of different people beat in the same rhythm.
The results of the work were published in the journal Communications Psychology.
In addition to heart rate, scientists were concerned with unified respiration and skin conductivity.
To take part in the experiment, the researchers recruited a group of 144 volunteers who were asked to communicate with each other.
At this stage, the scientists were able to confirm that the physiological synchrony they were studying occurred when the participants were perceived as being maximally attractive.
Another group of 48 people was then recruited and tested in a speed dating mode.
It turned out that some people were more prone to physiological synchronization.
When judging their interlocutor to be more attractive in terms of romantic relationships, these people unconsciously adjusted their breathing and pulse to match the rhythm of their interlocutor.
For this reason they were called “super-synchronizers,” and this is not some kind of skill that comes with experience, but fundamental sensorimotor abilities that provide a person with the ability to adapt.
It was also possible to find out that by synchronizing the pulse and breathing, a person improves the regulation of the body's systems.
It is possible that the phenomenon has a deeper meaning and may also be evidence of cognitive and evolutionary advantages.
