The Loneliness Epidemic, and the Oldest Fix We Have

The loneliness epidemic explained: what the Surgeon General warned about, what the data shows, why adults drifted apart, and why a weekly shared activity helps.

The loneliness epidemic is the name for a public health warning: large numbers of people feel lonely or live with few social ties, and that disconnection is linked to real harm to health. In 2023 the U.S. Surgeon General made it official, issuing an advisory that called loneliness and isolation an epidemic. The term is a metaphor, since loneliness is not contagious. But the numbers behind it are serious, and the oldest fix we have is also one of the simplest: seeing the same people, doing the same thing, again and again.

The quick answer: about half of U.S. adults report measurable loneliness, according to the Surgeon General. About one in five say they felt lonely for a lot of the previous day. Social disconnection is linked to higher risk of early death, heart disease, stroke, and dementia. The causes are mostly structural, and so is the fix: a regular shared activity that brings people together without anyone having to plan it.

This article explains the epidemic itself. If you want the practical case for games as a remedy, read our companion piece on board games and loneliness.

What does “loneliness epidemic” mean?

Two related ideas sit under the phrase.

Loneliness is a feeling: the gap between the connection you want and the connection you have. You can feel lonely in a crowded room or a marriage.
Social isolation is a fact: having few relationships or little contact with other people. Someone can be isolated and feel fine, at least for a while.

Researchers measure both, and both are linked to health. When public health officials say “epidemic,” they mean the problem is widespread, has measurable effects, and calls for a public response, not just private coping.

What did the Surgeon General’s loneliness advisory say?

In May 2023, Surgeon General Vivek Murthy released Our Epidemic of Loneliness and Isolation, an advisory of the kind usually reserved for threats like smoking. Its main points:

It is common. Even before the COVID-19 pandemic, about half of U.S. adults reported measurable levels of loneliness.
It is linked to health. The advisory said lacking social connection raises the risk of premature death to a level comparable to smoking up to 15 cigarettes a day. It also cited higher risks of heart disease (29 percent), stroke (32 percent), and, for older adults, dementia (about 50 percent).
People spend less time together. The advisory reported that Americans spent about an hour a day with friends in person in 2003, and about 20 minutes a day by 2020. For people aged 15 to 24, in-person time with friends fell by close to 70 percent.
It is a shared problem. The report called for action from communities, workplaces, schools, health systems, and governments, not only individuals.

Those figures describe risk across large groups, not a guarantee for any one person. But they put loneliness on the same list as other well-known health risks.

What do loneliness statistics show?

Several independent sources point in the same direction.

Fewer close friends. In 2021 the Survey Center on American Life found that 12 percent of Americans said they had no close friends, up from 3 percent in 1990. Nearly half (49 percent) said they had three or fewer, up from 27 percent. The share with ten or more close friends fell from 33 percent to 13 percent.

Daily loneliness. In a 2024 survey, Gallup found that 20 percent of U.S. adults felt loneliness “a lot of the day yesterday.” That was below the peak of 2020, but up from several quarters near 17 to 18 percent.

A global pattern. In June 2025 the World Health Organization’s Commission on Social Connection estimated that about one in six people worldwide experience loneliness, and that loneliness is linked to roughly 871,000 deaths a year. It found loneliness most common among adolescents and young adults.

How strong is the link between loneliness and health?

The best-known research comes from Julianne Holt-Lunstad and colleagues at Brigham Young University.

A 2010 meta-analysis in PLoS Medicine pooled 148 studies with about 309,000 people. People with stronger social relationships had about 50 percent greater odds of survival over the study periods.
A 2015 follow-up in Perspectives on Psychological Science looked at about 70 studies with more than 3 million people. Social isolation, loneliness, and living alone were each linked to higher odds of death, by roughly 26 to 32 percent.

These are associations. Studies like these cannot prove that loneliness alone causes illness, and researchers say so. But the pattern holds across many countries, ages, and study designs, which is why health agencies now take it seriously.

Is loneliness really getting worse?

Honestly, it is debated. Loneliness is hard to measure, surveys ask different questions, and some long-term data are thin. Gallup’s numbers, for example, have moved up and down since 2020 rather than climbing in a straight line.

What is clearer is that the structures that used to bring people together have weakened. Fewer close friends, less time with friends in person, and more time alone are measurable trends. Whether you call it an epidemic or not, the conditions for loneliness have grown.

Why did adults drift apart?

No single cause explains it. A few forces stack on top of each other.

Third places disappeared

Sociologist Ray Oldenburg used the term “third place” for somewhere that is neither home nor work, where you see the same people regularly: a diner, a barbershop, a pub, a club hall. Many of those places have closed or changed into spots where people come and go alone. Our article on the third place problem explains why that matters so much.

Work moved home

Remote and hybrid work gave many people time back. It also removed the daily, unplanned contact that used to happen at the office: the hallway chat, the lunch table, the after-work drink. For many adults, coworkers were a large share of their social world.

Life events break up groups

Moving to a new city, starting a family, changing jobs, divorce, and retirement each remove a group of people you used to see without trying. Any one is manageable. Several in a few years can empty a calendar. Our piece on why friendships fade with age walks through how that drift happens.

Screens filled the gaps

Phones and streaming make time alone easy and pleasant. They are not the villain on their own, but they make it easier to skip the small effort that in-person time takes.

Fewer shared groups

Membership in clubs, leagues, and religious and civic groups has declined over decades. Those groups did quiet work: they put people in the same room on a schedule.

What actually helps with loneliness?

The research on friendship points to a practical recipe. Friendships form through repeated contact with the same people, in a setting where everyone can relax. One study from the University of Kansas estimated it takes about 50 hours together to become casual friends and more than 200 to become close friends.

That is why one-off events rarely fix loneliness. What helps is something that recurs:

Same people. A standing group, not a new crowd each time.
Same time. A weekly slot nobody has to plan.
Something to do. A shared activity carries the conversation, so nobody has to perform.

Choirs, sports leagues, volunteer shifts, and classes all fit. So does a weekly game. A game gives strangers a reason to sit together, gives quiet people something to focus on, and creates small shared stories that turn into friendship over time. Our guide on how to make friends as an adult lays out a step-by-step plan.

None of this replaces professional help. If loneliness comes with depression, hopelessness, or thoughts of self-harm, talk to a doctor or a mental health professional. In the U.S., you can call or text 988 to reach the Suicide and Crisis Lifeline.

Why is a weekly game the oldest fix we have?

People have gathered around games for thousands of years. Board games turn up in ancient Egypt and Mesopotamia; cards, dominoes, chess, and mahjong have anchored social life across many cultures. The game was rarely the point. It was the reason to show up.

A weekly game night rebuilds what the loneliness data says we lost: a regular place, the same faces, and something to do together. It is cheap, it works indoors in any season, and it welcomes people of any age. The Ludarium is building toward a membership game lounge in Indianapolis for exactly this reason: a third place built around the table.

FAQ

What is the loneliness epidemic?

It is a term for widespread loneliness and social isolation, and the health harm linked to them. The U.S. Surgeon General used it in a 2023 advisory that said about half of American adults report measurable loneliness.

What did the Surgeon General say about loneliness?

The 2023 advisory said social disconnection raises the risk of early death to a level comparable to smoking up to 15 cigarettes a day, and is linked to higher risk of heart disease, stroke, and dementia. It called for action from communities and institutions, not only individuals.

How many adults are lonely?

Estimates vary by how the question is asked. The Surgeon General cited about half of U.S. adults reporting measurable loneliness. Gallup found 20 percent felt lonely for a lot of the previous day in 2024.

Common causes include moving, remote work, retirement, changes in family life, fewer third places, and less membership in clubs and community groups. Most are structural, not personal failings.

How can adults build friendships again?

Pick one recurring activity with a built-in task, such as a weekly game night, a choir, or a league. Go every week for at least two months. Repeated time with the same people is what turns acquaintances into friends.
