Face-to-face talks synchronize brains, HRV, and skin moisture

New research published in *Communications Biology* by lead author Dr. Li-Feng Hsieh suggests that real-life conversations synchronize brain activity, heart rate variability (HRV), and electrodermal activity (skin moisture) between two people. The study, using fMRI and biosensors on 26 pairs, found that this physiological connection was stronger during face-to-face interactions compared to video calls. It adds a biological data point to the 'being on the same wavelength' feeling, favoring in-person connection over screens for deeper engagement.
