Every Wednesday I offer tips for adulthood.

Amid the flurry of research on happiness these days, it’s easy to lose sight of another side of adulthood: many of us all suffer from loneliness.

As a recent article in The Atlantic noted, various studies have shown loneliness rising drastically over a very short period of recent history. One leading scholar of loneliness has estimated that as many as one in five Americans suffers from being lonely.

Feeling isolated not only has adverse effects on our mental health, but negative consequences for our physical health as well. One study found that people who were not connected to others were three times as likely to die over the course of nine years as those who had strong social ties. Another study found that people who are lonely are at higher risk for inflammatory diseases. One study even suggested that loneliness may be contagious.

If we are indeed in the midst of a “loneliness epidemic,” it’s worth asking:  what causes loneliness?

1. Aging. Sure, depression is common in old age, and people are living longer than ever before. But the role of the elderly within communities is also shifting, from traditional societies where the elderly held a hallowed place as the repository of community customs, history and stories, to post-industrial societies where this guidance function is much less valued. As this sociological shift takes place, older people risk feeling marginalized from their families and neighborhoods, particularly if they end up in nursing homes.

2. Death and divorce. Writing about the loneliness epidemic, one national columnist talked about the “three D’s”: death, divorce and delayed marriage. It’s not hard to see why the death of a spouse would trigger a feeling of loneliness. Jane E. Brody had a lovely meditation on this topic in The New York Times not long ago. The divorce point is more interesting. We know, for example, that Online dating has seen its highest growth rate among Boomers. But all that dating doesn’t necessarily translate into feeling less lonely. Sometimes it just reinforces it, as people bounce from one partner to another.

3. Social Media. Which brings us to social media. The central thesis of The Atlantic article I referenced earlier is that even as we become ever more connected as a society digitally, we are becoming less immersed in real-life social ties. This is not a new thesis, and as someone who spends a lot of time Online I can readily attest to its accuracy. What’s interesting about the article is that it looks very closely at Facebook, and references research suggesting that while “active” interaction on Facebook – i.e. making a comment on someone’s status update, sending a private message – tends to make people feel less lonely, just passively scrolling through other people’s feeds and hitting the odd “like” button can make you feel more lonely. An earlier study offers some insight into this finding:  because we are psychologically predisposed to over-estimate other people’s happiness, when we see the invariably upbeat, relentlessly witty and sometimes just plain gushing status updates that pretty much define Facebook, it makes us feel worse about ourselves.

4. Commuting. Here’s a factor I hadn’t considered, but which makes perfect sense. According to Robert Putnam, the famed Harvard political scientist and author of Bowling Alone, long commuting times are one of the most robust predictors of social isolation. Specifically, every 10 minutes spent commuting results in 10 percent fewer “social connections.” And those social connections tend to make us feel happy and fulfilled.

5. Genetics. There is also likely a genetic component to loneliness. One survey of loneliness among twins showed much less variability in the self-reporting of loneliness among identical twins than among fraternal ones. ‘There’s also been a lot of fascinating research coming out of The University of Chicago about the way in which loneliness shapes brain development and vice versa, suggesting a neural mechanism in explaining loneliness.

    I find the potential of a genetic component to loneliness most surprising. As for the rest, it’s logical and so interesting, especially when you look beneath the surface at how these 21st century “connectors” can actually aggravate feelings of isolation rather than ease them.

    Yes, @biglittlewolf, I also found that intriguing. Thank Goodness for twin studies!

    Interesting round-up of links, as always. I do find quite ironic & baffling the idea that loneliness might be “contagious,” as “catching” loneliness from others seems to suggest one might need to be in contact with other lonely people, which–you know, might make one feel less lonely?

      well spotted @naomi, as we say over here. Have a look at the link to that earlier study and see how they explain it. I think the point is that the more lonely people feel subjectively, the more likely they are to move to the edge of their communities and then there is a domino effect….and everyone is suddenly on the “outside.” But you’re right, as I write that it doesn’t sound like it makes much sense, does it?

    You mentioned delayed marriage as a cause of loneliness and I think this is a huge cause of modern loneliness. We have wonderful careers and beautiful friendships but the longer it takes to find a partner the more we start to think about taking care of ourselves in our old age and the possibility of not having someone to have kids with and that kind of loneliness is a heavy weight to manage.

    Interesting post, thanks.

      Good point, @Ishyathim. I think that’s absolutely part of it. Thanks for dropping by!~

    The link between commuting and loneliness was new to me. Interesting!
    Genetic variation certainly explains a lot of the differences we have in our personalities and social life and can probably be a ok pointer for “risk of loneliness”.
