Social connection is not a “nice-to-have” extra in life — it is as vital to our health as food, water, and sleep. Our relationships profoundly shape how long we live, how well our brains function, and how we feel day to day.

A recent study followed U.S. adolescents into adulthood and discovered some important lessons for all of us. The study found that teens who felt more connected to their families were much more likely to report strong, satisfying social relationships in their 30s and 40s. This study focuses on adolescent experiences, but its message is also important to older adults and those who care for them.
