🧬 Why It Matters: The Scientific Link Between Social Interaction and Longevity

Research shows that social connections are a key factor in longevity, alongside nutrition and physical activity.

🔬 What Science Says:

  • People with strong social ties live longer and get sick less often
  • Loneliness increases the risk of premature death by 26% (Harvard, WHO data)
  • Social activity reduces cortisol (stress) levels and boosts immunity
  • Support from others helps cope better with illness and challenges

🤝 Effects on Body and Brain:

Social Interaction Effect What Happens
Less stress Stable heart rate and blood pressure
More dopamine and oxytocin Improved mood and motivation
Protection from dementia Active brain, less degeneration
Mental health support Lower risk of anxiety and depression

Social interaction is the “vitamin of longevity.”
It requires no prescription but impacts health as much as nutrition and exercise.
