A study at the Hebrew University of Jerusalem found that perfectly-matched couples can become biologically synced within two minutes of meeting.

The researchers found couples will begin synchronizing psychical movements - such as smiling, nodding and moving their limbs - within this time.

They will also have a similar skin sweat rate by the two-minute mark as their bodies begin biologically syncing up.

“Connecting with a partner depends on how well we can synchronize our bodies,” said study author Dr Shir Atzil at the Department of Psychology at the Hebrew University in Jerusalem.

“The study showed that within two minutes into the date, physiological synchrony is predictive of the romantic interest.”
