What to know about What makes some couples bounce back from stress so quickly? New clues emerge from cortisol and partner behavior

The article reports on two studies from the Université de Montréal examining how sexual and gender diverse (SGD) couples and cisgender heterosexual couples recover from acute stress. The findings suggest that SGD couples may exhibit more efficient physiological recovery and higher levels of coordinated support behaviors.
