Why Brains Need Friends

The Neuroscience of Social Connection

Headlines have made clear that we are in a crisis of loneliness, but the conversation has yet to cover how spending time with others impacts the body and mind on a cellular level—and why this knowledge is part of the way forward. Renowned neuroscientist Dr. Ben Rein dives into the fascinating science of social interaction, revealing how modern life is challenging our ancient instincts. Rein uncovers the mesmerizing biological factors at play in our moments together, from small talk with baristas to deep conversation with friends, and shares how to leverage this knowledge to our advantage as we seek happiness and health. Enlightening and empowering, this powerful book reveals:​

  • Why isolation increases the risk of death by any cause.

  • How the brain experiences virtual interactions differently from in-person encounters.

  • The science of likeability and the secrets of making a positive impression.

  • The neuroscience of empathy and deep connections.

  • How relationships with animals can support our health.

  • How some drugs enhance social connections, while others impair them.

  • Strategies for improving your social life to maximize benefits to your health.

Weaving together cutting-edge scientific discoveries, storytelling, and practical advice inspired by data, Rein reveals how our brains and our bodies are made stronger by connection, and ultimately why brain health is critical to our well-being.
