Before coronavirus we were dying of loneliness. Can a pandemic help America heal?

Doctors fight epidemics like Covid-19 by following contagion from person to person, eventually mapping a complex series of our physical encounters with friends, co-workers and acquaintances.

It’s a piece of medical detective work that also reveals our deep interconnectedness. But before Covid-19 went global, Dr. Vivek H. Murthy identified another epidemic, one spread not through connections, but in their absence.

“Loneliness is an important health priority,” Murthy said, who served as the US Surgeon General from 2014 to 2017. “There’s growing evidence that we have a strong association between loneliness and concerning health outcomes.”

Americans, Murthy said, are lonely. While the feeling is common, it’s also serious.

In a new book, “Together: The Healing Power of Connection in a Sometimes Lonely World,” available April 28, Murthy makes the case that with health implications that include heart disease and stroke, dementia and depression, loneliness is a topic that we can’t afford to ignore.

And now, as Americans use social distancing to reduce the spread of coronavirus, Murthy sees the looming threat of an ongoing “social recession” that could leave us coping with growing disconnection for years to come.

But the virus, he says, could also be an opportunity for meaningful change.

The health risks of being lonely

A little bit of loneliness isn’t necessarily a bad thing, said Murthy, who was nominated for the post of surgeon general by President Obama in 2013.

He suggested thinking of the feeling as a message from your body.

“It’s actually a natural one that we have in response to a lack of social connection in our lives,” he explained. “In the same way we have hunger or thirst, when we lack for something we need for survival, our body signals us with loneliness.”

When loneliness goes unaddressed over the long term, however, it can start affecting both physical well-being and mental health.

“Loneliness places us in a physiological stress state,” said Murthy. “When stress states are very intense or prolonged, they can, over time, generate higher levels of inflammation in our body, they can deplete us emotionally.”

In a 2010 meta-analytic review of the data on loneliness, Julianne Holt-Lunstad, professor of psychology and neuroscience at Brigham Young University, found that strong social relationships increase an individual’s likelihood of survival by 50%.

A lack of human connection, she found, has an impact on longevity similar to the effects of smoking 15 cigarettes a day; it’s worse than drinking too much or getting too little exercise.

Also in 2010, researchers Louise Hawkley and John Cacioppo found that loneliness is correlated to diminished sleep quality, accelerated aging, cognitive decline, suicide and chronic depression.

Additional studies have found links between loneliness and a long list of other health conditions, including heart disease, stroke, dementia, high-blood pressure and anxiety.

How bad is the problem?

Studies assessing Americans’ sense of loneliness vary from about a quarter to nearly half of the population.

The Kaiser Family Foundation found in 2018 that 22% of Americans felt lonely or socially isolated. That same year, a Cigna study put that number at almost half the country’s adults — more than 116 million people.

“The bottom line is it’s a very, very substantial portion of the population,” Murthy said. “This is more than the number of people who have diabetes in the Unites States, it’s more than the number of people who smoke.”

And it’s not just the United States. The Kaiser Family Foundation study found that 23% of British adults and 9% of Japanese adults report loneliness and social isolation. Murthy noted that global loneliness data is not as well developed as other public health data.

But despite the widespread problem, Murthy said the shame and isolation associated with feeling lonely make it hard for many Americans to say they’re having trouble.

“When you look around you, if you’re judging other people’s lives by their social media feeds and what they talk about in group settings, it seems more often than not that other people are leading perfect lives,” he said. “I think that makes it hard to be vulnerable and open about loneliness.”

And while the social distancing required to slow Covid-19 is making Americans more physically isolated, Murthy hopes it’s also sparking conversations about the importance of social connections in our lives.

“We are all going through this life-altering ordeal, and our lives have all been turned upside-down,” he said. “Most people recognize it. Many people are, in fact, struggling.”

That shared challenge can be an opportunity, Murthy said.

“When we recognize that we, and everyone, are vulnerable,” he said, “it can make it easier to reach out, to check in with someone, to be honest about how you’re doing as well.”
