Treatment of a serious mental illness that can lead to suicide, such as major depressive disorder, often centers on medication and talk therapy with little or no consideration of factors such as social isolation or financial duress. Now, there's a growing movement to address loneliness not just through personal choices but also through public policy.

The research is clear: Among the various complex issues that contribute to suicide, loneliness is a big one. It's a particularly strong predictor for older adults, who have the highest rates of suicide, and for youths, for whom suicide is the second-leading cause of death.

Humans are social animals. When we feel cut off from one another, our stress levels increase, our immune systems are disrupted and ultimately we're likely to die earlier (by suicide or by other causes). An oft-cited study concluded that being socially disconnected is as harmful to one's health as smoking up to 15 cigarettes a day.

And it's getting worse.

Mental health researchers and clinicians say a variety of factors are fueling increased rates of loneliness in America, including the rapid growth of technology, such as smartphones and artificial intelligence; increased political polarization; the shift to remote work since the COVID pandemic; and decreased participation in religious institutions.

With suicide rates remaining stubbornly high—often ranking among the top 10 causes of death in America—some advocates and people who have lost loved ones to suicide say increasing pathways to social connection could be a new frontier.

In this ongoing series, KFF Health News is examining new approaches to suicide prevention that shift the focus from stopping harm in moments of crisis to efforts that give people reasons to live well before they make fateful choices.

"If we want to reduce suicide rates in our country, which is absolutely essential, then a key part of that has to be fostering social connection," said Dr. Vivek Murthy, who served as surgeon general under Presidents Barack Obama and Joe Biden. "We have more than enough data to support this as being an important area of focus."

In 2023, Murthy released the first U.S. Surgeon General's Advisory on loneliness as a public health issue, with more than 300 supporting citations. He's also written a book on the topic and is touring the country discussing the value of social connection.

"To help someone else feel less alone, to help them feel seen and understood and valued," he told KFF Health News, "That can be one of the most powerful interventions that we make."

A role for elected officials

Curing loneliness may seem like the responsibility of families and neighbors, people making one-to-one connections. But Murthy says elected officials have work to do, too.

They can use their bully pulpits to turn this into a mainstream issue, he said. They can create microgrants to support grassroots ideas from community entrepreneurs and invest in "social infrastructure," he added.

That term refers to things in the community that support the development of social connection, from physical spaces, such as libraries and parks, to policies and programs, such as building public transportation and fostering volunteer groups.

"These all matter and impact whether people gather," Murthy said.

However, investing in public institutions and infrastructure is a costly endeavor that can seem unreasonable when local officials are struggling to balance budgets without increasing tax burdens.

That's where creativity can kick in.

A health system and a museum in Charlotte have teamed up to provide "prescriptions" for people to attend art classes or live performances together. In Tennessee, the city of Chattanooga is working on community ideas to increase connection and time in nature, including benches where people can speak with volunteer listeners. And across the country, men's sheds have popped up as places where men can work on projects side by side and discuss their mental health.
