The most underrated factor for a long, healthy life

As millions set health goals for 2026, one of the most powerful interventions rarely makes the list: social connection. Data from the World Health Organization shows that staying connected reduces inflammation, improves mental health, and helps prevent early death, while isolation significantly increases dementia risk.

From an ancestral health perspective, this makes sense: we evolved living in close-knit tribes, not in isolation behind screens. Our biology expects regular, meaningful human contact. The practical application is to pair social time with other healthy habits you're already building. A weekly walk with a friend, a standing workout class, or regular shared meals can reinforce both your fitness goals and your need for connection. As you plan your resolutions this year, consider that the people you spend time with may matter as much as the food you eat or the exercise you do.
