When we’re in a relationship with someone we love, trust and respect, we often talk about how “in sync” with our significant other we feel. Turns out, there’s more scientific, biological truth to that idea than you might think. This post from Bustle highlights a recent study conducted by the International Behavioral Neuroscience Society about how trust can be linked to in sync heartbeats, whether in a romantic relationship or just friendly or familial. In addition to just leading to synced up heartbeats, trusting your significant other is often linked to a surprising number of other health benefits as well.

For one thing, people who are in loving, trusting and mature relationships experience lower stress levels than un-coupled people, or people who are in volatile relationships. Being in a loving partnership helps to combat psychological distress, leading to an overall feeling of happiness and mental well-being. Additionally, people who are married or coupled up (and remain so for the long haul) tend to have longer lifespans than those are not. Your psychological health contributes to your overall physical health, so having a happy and healthy relationship with your partner can lead to a happy and healthy life overall.
