This matters because relationships are part of what our brains and our bodies need. They are part of our emotional immune system and part of what makes us happy and healthy, especially during these incredibly difficult and often lonely twentysomething years. Yet, my clients and readers tell me—and my students on Semester at Sea said it too—that, thanks in no small part to our devices, not only do relationships feel less available as sources of happiness or support but relationships themselves have become the stressors.
