“Our epidemic of loneliness and isolation has been an underappreciated public health crisis that has harmed individual and societal health. Our relationships are a source of healing and well-being hiding in plain sight – one that can help us live healthier, more fulfilled, and more productive lives,” said U.S. Surgeon General Dr. Vivek Murthy. “Given the significant health consequences of loneliness and isolation, we must prioritize building social connection the same way we have prioritized other critical public health issues such as tobacco, obesity, and substance use disorders. Together, we can build a country that’s healthier, more resilient, less lonely, and more connected.”
The physical health consequences of poor or insufficient connection include a 29% increased risk of heart disease, a 32% increased risk of stroke, and a 50% increased risk of developing dementia for older adults. Additionally, lacking social connection increases risk of premature death by more than 60%.
In addition to our physical health, loneliness and isolation contribute substantially to mental health challenges. In adults, the risk of developing depression among people who report feeling lonely often is more than double that of people who rarely or never feel lonely. Loneliness and social isolation in childhood increase the risk of depression and anxiety both immediately and well into the future. And with more than one in five adults and more than one in three young adults living with a mental illness in the U.S., addressing loneliness and isolation is critical in order to fully address the mental health crisis in America.
