Culture shock and mental health: why 9 in 10 expats struggle (and what actually helps)

What is culture shock, exactly?

Culture shock is what happens when your brain loses the automatic, unconscious rules it used to navigate daily life, and hasn’t built new ones yet. It’s not homesickness, though homesickness usually turns up alongside it, and it’s not a character flaw or a sign you’re not cut out for life abroad. It’s a genuine psychological response, and it’s astonishingly common: around 92% of expats find adapting to a new culture challenging, with roughly two-thirds describing it as extremely or very difficult.

I’ve lived a lot of my adult life outside the UK, and I’ve stood in a shop abroad completely unable to explain what I needed, feeling about four years old, and feeling absolutely ridiculous about how much that small failure knocked me sideways for the rest of the day. That’s culture shock. It’s rarely the big dramatic thing. It’s the accumulation of a hundred small ones.

How does culture shock actually affect your mental health?

Culture shock affects your mental health by keeping your nervous system in a low-grade state of alert for far longer than it’s built to sustain, and over time that shows up as anxiety, low mood, irritability, and exhaustion that sleep doesn’t fix. Researchers have found that expat workers face roughly a 50% higher risk of mental health difficulties than people who stay in their home country, and that psychological adjustment problems are a major factor in up to 40% of international assignments ending early. That’s not a small or fringe statistic; that’s a huge proportion of people quietly struggling with something nobody warned them about.

Key takeaways

• Around 87% of expats report feeling isolated at some point while living abroad, most commonly because they miss friends and family.
• Expat workers face roughly a 50% higher risk of mental health difficulties than people who stayed at home.
• Culture shock isn’t a personal failing. It’s a documented, predictable response to sustained cultural and sensory overload.
• During periods of heightened isolation, one study found expat loneliness running significantly higher than among people who never left home.
• Online therapy has been shown to work as well as in-person therapy for anxiety, depression, and adjustment difficulties, which is exactly what culture shock tends to trigger.
• You don’t need to wait until things feel unmanageable before getting support. Earlier input tends to be easier than crisis management.

Why do so many expats feel isolated, even when life abroad looks good on paper?

Expats feel isolated because the ordinary social scaffolding you don’t even notice at home, the colleague who says hello in the corridor, the neighbour who waves, the friend you can call without a time difference, mostly disappears when you move, and it takes real time and effort to rebuild. Research from AXA Global Healthcare found that almost nine in ten expats have felt isolated during their time abroad, with half saying missing friends and family was the main reason, and language barriers and a lack of local support network also cited as significant factors. Separately, research from Cigna Healthcare’s International Health business found that nearly half of globally mobile workers describe themselves as lonely.

That loneliness gets sharper during periods of extra stress. One study of long-term expatriates found loneliness rates of over 77%, compared with under 47% among people who hadn’t left home, during a period of heightened global disruption. We are social creatures. It doesn’t matter how independent or capable you are, or how much you wanted this move; being cut off from your usual people has a cost, and it’s not a cost you’re imagining.

Here’s a rough guide to what the stages tend to look like, though nobody moves through them in a neat line:

Is it just culture shock, or something more serious?

It’s worth paying attention if the low mood, anxiety, or exhaustion isn’t easing as you settle in, or if it’s getting in the way of work, relationships, or basic day-to-day functioning. Culture shock on its own tends to soften with time and familiarity. If it isn’t softening, or if you’re withdrawing further rather than gradually reconnecting, that’s a sign to bring in some outside support rather than waiting it out. This is especially worth thinking about if you’re also navigating something like how trauma affects the brain, since a difficult move can reactivate older patterns that have nothing to do with the country you’re currently living in.

Does online therapy actually work for expats?

Yes. Online therapy has repeatedly been shown to produce outcomes comparable to in-person therapy, including for the areas culture shock tends to hit hardest. A 2019 meta-analysis of 33 studies found that the majority of comparisons between online and face-to-face therapy showed comparable results, and more recent research specifically on adjustment difficulties and expat populations backs this up.

I’ll say this plainly, because I think it matters: I’m not neutral on this one. I think online therapy is an excellent, sometimes better, fit for expat life, and I’d recommend it without hesitation to anyone living somewhere that doesn’t have easy access to a therapist who works in their language or understands what it’s like to be the outsider in the room. You’re not settling for a lesser option. You’re removing the single biggest practical barrier, which is geography, without losing the quality of the work. If you want to read more about how this actually works in practice, I’ve written about whether online therapy is suitable for expats and whether online counselling is genuinely effective in more depth.

What can you actually do about culture shock right now?

Start by lowering the bar. You are not trying to feel completely at home in six weeks, you’re trying to find an acceptable level of okay for right now, and that’s a much more realistic and much kinder target. A few things that genuinely help:

• Keep at least one regular point of contact with home, whether that’s a weekly video call or a standing message thread, rather than letting contact happen randomly.
• Learn the specific local phrases you need for the situations that trip you up most, not the whole language, just your problem areas.
• Notice when you’re comparing your new life to a highlight reel of your old one. Home wasn’t frictionless either; you’d just built up the skills to handle its friction without noticing.
• Ask yourself what you’d say to a friend going through exactly this. You’d almost certainly be far gentler with them than you’re currently being with yourself.
• Get support before it becomes a crisis. A regular space to process what’s happening, ideally with someone who understands both the psychology of adjustment and the practical reality of expat life, can make an enormous difference to how long this period lasts.

Frequently asked questions

Is culture shock a mental health condition?

No, culture shock itself isn’t a diagnosis, it’s a recognised psychological and physical response to sustained cultural adjustment. It can, however, contribute to or worsen anxiety and low mood if it isn’t addressed, which is why it’s worth taking seriously rather than dismissing as something you should just push through.

How long does culture shock last?

It varies hugely from person to person and depends on factors like language, local support, and how different the new culture is from what you’re used to. Many people notice a real shift within several months, though for some it takes longer, and dipping back into frustration after a period of feeling settled is completely normal.

Can online therapy help with culture shock?

Yes. Research consistently shows online therapy produces outcomes comparable to in-person therapy for the anxiety, low mood, and adjustment difficulties that culture shock commonly brings, and it removes the barrier of needing to find a suitable therapist in your local area. You can read more about the specific mental health challenges of living abroad if you want to understand the fuller picture.

What are the early warning signs I should look out for?

Watch for low mood or anxiety that isn’t easing with time, sleep and appetite changes, withdrawing from the few connections you do have rather than gradually building more, and a persistent sense that you’ve made a mistake. None of these mean something is wrong with you; they mean it’s a good time to get some support.

Is it normal to still struggle after living somewhere for years?

Yes. Culture shock and adjustment aren’t strictly time-limited, and life changes, like a new job, a relationship ending, or simply a harder year, can bring old adjustment difficulties back to the surface even after you’ve felt settled for a long time.
