One recent survey found that 1 in 5 millennials report having no close friends. With so many people experiencing some form of loneliness, the U.S. is in the midst of a loneliness epidemic. Studies on the health effects of loneliness paint a grim picture, linking loneliness to high blood pressure, heart disease, and cognitive decline. Not to mention, young adults who report being lonely are more likely to experience mental health problems and be out of work than their peers. Loneliness is complicated, and clinicians may be unsure how to reach this generation.
