Loneliness is now a bigger health risk than smoking 15 cigarettes a day.
That’s not a metaphor. That’s the conclusion of researcher Julianne Holt-Lunstad, whose landmark studies on social isolation have quietly reframed how we understand public health. We have anti-smoking campaigns, warning labels, nicotine patches, and support groups for addiction.
We have almost nothing for the lonely.
And the lonely are everywhere.
The People You’d Never Expect
They’re in your office. In your building. At your dinner table. They might be you — surrounded by people, busy, professionally successful, connected online, and quietly, privately, achingly alone.
This isn’t a problem of introverts or hermits or people who struggle socially. The loneliest people I meet in my practice are often the most socially capable. The ones who show up, perform connection beautifully, fill every silence — and go home to silence.
High-functioning loneliness is one of the most underdiagnosed experiences I encounter working as an English speaking therapist in Germany and online with international professionals. It hides behind full calendars, impressive LinkedIn profiles, and the carefully curated appearance of a life well-lived.
It doesn’t look like loneliness. That’s exactly why it goes untreated for so long.
The Expat Experience
Expats and internationally mobile professionals know this particularly well.
When you relocate — whether for love, work, adventure, or all three — you leave behind the invisible scaffolding of belonging. Your language, your community, your sense of where you fit. The friendships that took years to build. The family you could call at 10pm when something went wrong.
You rebuild professionally within months. The social and emotional rebuilding takes years. And nobody talks about that part of the international adventure — the part where you’re sitting in a beautiful city, doing interesting work, and feeling completely unseen.
As an English psychotherapist working with expats in Munich and online across Europe, I hear this story constantly. It shows up as anxiety, as relationship strain, as a vague but persistent sense that something is missing despite having everything you were supposed to want.
It’s loneliness. It just doesn’t always come with that label.
Why We Got Here
Authors like Johann Hari have written brilliantly about the connection crisis. Scott Galloway has built an entire platform around the collapse of male community. Podcasters, economists, sociologists — everyone is talking about it.
And yet somehow it still feels like nothing is actually changing.
We know that community has collapsed. We know that work no longer provides belonging the way it once did. Religion, neighbourhood, extended family — the structures that used to hold people together without effort — have quietly eroded over the past few decades.
We replaced them with productivity apps. LinkedIn connections. Parasocial relationships with podcast hosts who feel like friends but don’t know we exist.
And now we’re surprised that everyone feels so lost.
The response has largely been to treat loneliness as a personal failing. A personality issue. Something to fix by putting your phone down and going to socialise.
But loneliness isn’t a personality flaw. It’s the predictable consequence of a world that systematically dismantled the structures that used to hold us together — without replacing them with anything meaningful.
What Loneliness Actually Does To Us
Chronic loneliness isn’t just emotionally painful. It’s physically dangerous.
Research shows that social isolation increases the risk of heart disease, stroke, dementia, and premature death. It dysregulates the immune system, disrupts sleep, and keeps the nervous system in a state of chronic low-level threat response.
Your body experiences loneliness as danger. Because evolutionarily, it was. Being separated from the group meant not surviving.
That ancient alarm system is still running in modern bodies — in open-plan offices, in expat apartments, in the middle of busy cities where nobody knows your name.
What Actually Helps
Therapy for loneliness isn’t about teaching social skills or telling people to get out more.
It’s about understanding what gets in the way of genuine connection — the fear of vulnerability, the exhaustion of performing, the grief of what’s been lost in relocation or life transition, the anxiety about reaching out after too long alone.
It’s about rebuilding the capacity for real relationship. Not more contacts. Not a bigger network. Actual human connection — the kind where you don’t have to perform.
Online therapy for expats and international professionals has made this kind of support genuinely accessible for people who previously had no options in their language, in their time zone, with someone who understands their specific experience.
If you’re an expat or international professional struggling with loneliness — whether you name it that or not — you’re not broken. You’re having a completely human response to genuinely difficult circumstances.
The world got harder to belong to. That’s not your fault.
Be kind to yourself. And maybe — reach out to one person today. Not to network. Just to connect.
