I’m Fluent in Danish. So Why Am I So Tired?

I was halfway through presenting my patients when the words ran out.

I knew the message I needed to deliver. I was familiar with the patients, their histories, medications, observations, and next steps.

But suddenly, speaking felt exhausting. It was neither difficult nor impossible, just exhausting. This left me confused.

I have spoken Danish for over fifteen years. I studied nursing in Danish and use the language daily at work. I communicate with patients, colleagues, and families in Danish effortlessly, without mentally translating each sentence.

Why did I suddenly feel like I had nothing more to say?

I have stumbled while speaking Danish before. Of course I have. Anyone who speaks a language they didn’t grow up with knows what it feels like.

Sometimes a word slips away just when you need it. Other times, you know exactly what you want to say, but the sentence doesn’t come out as intended.

None of that worries me anymore. I’ve been doing this for too long. But this was different.

Something Wasn’t Right

I sensed my thoughts slowing, with familiar words suddenly feeling distant. Even though I was still speaking, it was as if I were grasping for each sentence rather than saying them naturally. Then I realized I didn’t want to continue talking, which was unusual for me. I pushed through the presentation anyway in an unusually slow and uninteresting manner. As soon as I was done, I excused myself and sought out my nurse manager. I explained that I was mentally drained and asked to go home, and she agreed without question. No lengthy explanation or proof of exhaustion was necessary. I went home, feeling genuinely grateful.

I’ve learned to value the culture I work in here in Denmark, where mental health is taken seriously. Being mentally exhausted is recognized as a valid concern, not something to simply endure.

But once I got home, I couldn’t stop thinking about what had happened.

There was one question I couldn’t shake. I’m fluent in Danish, so why was speaking it suddenly so tiring? That’s part of why I started Conversations with Folasade.

When Fluency Doesn’t Mean Effortless

For a long time, I believed fluency meant you had truly arrived. When learning a new language, you face struggles, make mistakes, search for words, and worry about being understood. Over time, it gets easier as you gain fluency. At some point, I think many of us assume the effort should entirely vanish. Yet I remain uncertain exactly how that happens.

Even after many years, I occasionally reflect on how I communicate. I pay close attention to my tone and how others respond. Sometimes, I pause to consider my words carefully, especially during important conversations.

Most of the time, I don’t realise I’m doing it; I’ve become accustomed to it. However, excelling at something doesn’t mean it requires no effort; perhaps that’s what I experienced that day. It wasn’t a matter of not speaking Danish or lacking professional knowledge, just exhaustion.

Nursing Makes It More Complicated

Working in a different language is one thing, but practising as a nurse in that language presents a whole new challenge.

When I talk to a patient, I must pay attention to more than just their words. Does their voice sound different today? Are they confused? Are they trying to communicate something but struggling?  Is there something in their speech I should notice? Am I communicating clearly?

Despite all this, I need to convey that information clearly to my colleagues. Sometimes, there’s little time to find the perfect word; you have to choose quickly. For me, working in a language I learned later in life can sometimes require extra effort. Even when I know what I want to say, it can be draining.

Still, it’s crucial that the person you’re speaking to fully understands you. Remember, tone, timing, and confidence all matter. Expressing confidence can also feel different when communicating in a language that isn’t part of your upbringing.

Looking back, I don’t believe what happened that day meant I couldn’t speak Danish well enough, nor that I wasn’t competent at my job. I think I was simply exhausted.

So I Started Looking for Answers

After that day, I became curious whether speaking a second language might have played a role in how exhausted I felt. So, I started reading.

I discovered that researchers have studied something called bilingual language control, the processes involved in managing and using more than one language. I also found research exploring the mental effort and fatigue that can sometimes accompany second-language use.

What interested me most was that the picture wasn’t simple. The effort required can depend on the person, their experience with the language, and the situation in which they use it.

That made sense to me. Speaking Danish during an ordinary conversation and presenting patients to an interprofessional team are not quite the same thing.

Still, none of this tells me exactly what happened that day. Danish may have played a part, or it may simply have been a demanding shift. Perhaps several things were happening at once.

The research didn’t give me an answer. It gave me another way of thinking about the question: being fluent in a language doesn’t necessarily mean that every situation in which you use it will feel effortless.

The Part Nobody Sees

The more I reflected on that day, the more I realised it wasn’t just about speaking Danish at work. It prompted me to consider what it truly means to build an adult life in another language.

You don’t simply learn to hold conversations; you learn to study, work, explain yourself when misunderstood, disagree politely, comfort others, joke around, sound professional when nervous, and even be yourself.

Interestingly, this last part can be complex because the person you are in one language may not feel like the person you are in another.

 I’ve lived in Danish for many years; it has become part of my professional identity and daily life, yet it’s not the language I grew up speaking.

That might matter more than we realise. I think I never fully appreciated this before.

People see fluency, hear confident speech, see you working, joking, explaining, and going about your day. But they don’t always see the effort required to reach that point. After years of functioning in Danish, I stopped noticing the effort, until that ordinary day when my mind suddenly reminded me.

You can be fluent and still be tired.

You can appear completely at ease while doing some underlying work. This doesn’t indicate any problem with you, nor does it mean you’re not fluent. Not every tough day can be solely attributed to language issues. I still don’t know exactly what led to my exhaustion that day; it could have been a particularly stressful day at work or other unrelated factors.

However, the experience changed my perspective on what it means to work and live in another language.

I’m Still Thinking About It

I don’t have a definitive conclusion about this story yet, as I am still reflecting on that day. However, I do know it sparked my curiosity about how much mental effort multilingual individuals invest in tasks that have become automatic and go unnoticed. I also wonder about the effects when that mental effort eventually takes a toll.

These are some of the questions I wish to explore here.

I want to talk about the experiences that often sit quietly underneath the lives we build. The things we get used to carrying because we don’t always have a name for them.

Maybe you live in another language too.

Maybe you’ve had a moment when words suddenly felt harder than usual.

Maybe you’ve wondered why something that normally feels effortless suddenly requires so much energy.

Or maybe your experience has nothing to do with language at all.

Either way, I’d genuinely love to hear from you.

Have you ever felt mentally tired from speaking or working in another language, even long after you became fluent?

I think there is something worth talking about in that tiredness. Something worth naming instead of quietly carrying alone.
