Forget fad diets and fitness crazes — the biggest predictor of a long, healthy life might just be your relationships. According to Dr. Robert Waldinger, director of the 80-year Harvard Study of Adult Development, deep human connection is what truly supports lasting well-being.
Speaking at the New York Times Well Festival, Waldinger revealed that researchers were “shocked” to find that the warmth and strength of someone’s relationships had a greater impact on their health than genetics or lifestyle factors. “How connected you are to others, and especially the quality of those connections, matters more than we realized,” he said.
The reason? Good relationships help regulate stress. When we’re supported and heard, our bodies respond by calming down — lowering blood pressure, improving sleep, and boosting immunity. On the flip side, isolation and loneliness can take a serious physical toll over time..
But it’s not enough to just have people in your life — you need to actively invest in those connections. Waldinger compared relationships to physical fitness: “We don’t expect to be in shape without effort. The same goes for staying emotionally connected.”
Even small gestures count. Making eye contact with a barista or having a quick chat with a neighbor can lift your mood and strengthen your sense of belonging. According to Waldinger, prioritizing connection isn’t just feel-good advice — it’s essential to living a longer, healthier life.
