Additionally, both partners showed similar patterns of heart rate and respiration, but women tended to adjust theirs to their partners more. This was true not only for physiological but for day-to-day emotional experiences as well.

Emilio Ferrer, a UC Davis psychology professor who has conducted a series of studies on couples in romantic relationships, found that couples connected to monitors measuring heart rates and respiration get their heart rate in sync, and they breathe in and out at the same intervals.

To collect the data, the researchers conducted a series of exercises, sitting 32 heterosexual couples a few feet away from each other in a quiet, calm room. The couples did not speak or touch.

The couples, in one of the exercises, were asked to sit across from each other and mimic each other, but still not speak, and researchers collected very similar results.

The researchers also mixed up the data from the couples. When the two individuals were not from the same couple, their hearts did not show synchrony, nor did their breathing closely match.
