Cosmonaut Valentin Lebedev kept a detailed diary during his time aboard Salyut 7, describing how the monotony had become so thick he could taste it. He described the station’s hum as something that bored into his skull, the sameness of every waking hour pressing against him like a physical weight. He didn’t reach for a word like “depression” or “anxiety.” He called it boredom. And then, like most of us, he looked for something to make it stop.

You don’t need to be orbiting Earth at 17,000 miles per hour to recognise that reflex. It happens at kitchen tables, on commuter trains, and in the dead hours of a Tuesday evening when you pick up your phone not because anyone has messaged you but because something inside you needs quieting. The context couldn’t be more different from Lebedev’s — you can leave the room, open a door, go anywhere — and yet the internal experience is structurally identical. A signal fires. A discomfort rises. And before it can fully form, your thumb is already moving toward the screen.

That instinct, the immediate reflex to kill boredom rather than sit with it, is one of the most universal human behaviours I’ve observed across fifteen years of studying people in confined, isolated environments. It shows up in space stations, Antarctic bases, and submarine crews. It shows up everywhere else too. And it costs us more than we realise.

Boredom is a signal. The problem is that we’ve built entire industries around helping people silence it before they hear what it’s saying.

What Boredom Actually Is (and Isn’t)

The common assumption is that boredom means you don’t have enough to do. Too little stimulation, not enough novelty, an empty calendar. But the research tells a different story. Boredom occurs when there’s a gap between what you need and what your current activity provides. It’s not the absence of things to do. It’s the presence of an unmet need you haven’t identified yet, as Space Daily has explored before.

Reinhard Pekrun’s Control-Value Theory, which has shaped how we understand achievement emotions for over a decade, frames boredom as emerging from a specific combination: low perceived value and low perceived control. Students experience it when they see learning activities as irrelevant, too easy or too hard, repetitive, or sense that the person leading them doesn’t care. That same mechanism operates in adults outside classrooms. When your work feels pointless, when your evening routine has calcified into something you endure rather than enjoy, boredom is telling you that the thing you’re doing doesn’t connect to something you value.

That’s a useful signal. Possibly one of the most useful emotional signals we have.

But the signal only works if you listen to it.

The Medication Reflex

When I say “medicate,” I don’t mean pharmaceuticals (though that happens too). I mean every strategy we use to make boredom go away without asking what it wants. The phone. The snack. The third episode. The online shopping tab. The scroll through social media that doesn’t actually relieve the underlying state and may worsen it.

Research on comfort eating reveals that boredom is one of the primary psychological triggers for eating when not hungry. A study examining why people reach for food in the absence of physical need found that boredom consistently emerged as a driver of emotional eating behaviour. The food wasn’t solving hunger—it was addressing the discomfort of inactivity and unfocused attention that participants reported experiencing.

Smartphones serve the same function, and the data here is striking. Research has found moderate correlations between academic burnout and problematic smartphone use. Burnout, which shares significant psychological territory with chronic boredom (emotional exhaustion, cynicism, a sense that effort won’t produce results), consistently predicted the kind of phone use that people themselves recognised as excessive and harmful.

This isn’t a mystery. When something inside you signals discomfort and you can make that signal disappear in under three seconds by picking up a glowing rectangle, you will pick up the rectangle. Every time. Unless you’ve deliberately trained yourself to do something different.

What I Learned in Isolation Chambers

During my years at ESA’s European Astronaut Centre in Cologne, I spent a lot of time studying what happens to people sealed inside simulated spacecraft for weeks and months at a time. Boredom was always part of the picture, but it expressed itself in ways that surprised us.

The crews who coped worst with isolation weren’t always the ones who reported the most boredom. They were the ones who treated boredom as a problem to be immediately solved. They packed every minute with activity, with scheduled tasks, with anything that would prevent the feeling from landing. And when the activity dried up, as it inevitably does in a confined space where you’ve already reorganised the supply cabinet twice, they had nothing left. The boredom hit them harder precisely because they’d been running from it.

The crews who did better were the ones who could sit with the feeling. Not passively. Not numbly. But with a kind of attentive curiosity about what the boredom was pointing toward. Some of them used it as a cue to reconnect with crewmates. Others recognised it as a sign they needed solitude, not stimulation. Some realised their boredom meant they’d lost connection to the purpose of the mission and needed to actively rebuild that sense of meaning.

In my recent piece on people who always need a project, I wrote about how constant productivity can be a defence mechanism against difficult internal states. Boredom is one of those states. Not the only one, but often the first one people encounter when they slow down.

The Emotional Cascade Problem

One of the most important things the research shows is that boredom rarely stays as boredom. Unaddressed, it cascades into other emotions that are harder to deal with and more damaging.

Educational psychology research has mapped this cascade with some precision. Confusion, when unresolved, tips into frustration. Frustration can become anger. And boredom, uniquely among negative emotions, can go unnoticed even as it crushes attention, engagement, and performance. Unlike anger or anxiety, which announce themselves loudly, boredom seeps in. You can be deeply bored and not recognise it as boredom. You just know something feels flat, dull, wrong.

This stealth quality makes boredom particularly dangerous in long-duration spaceflight. An astronaut who is angry will typically flag it, or their crewmates will notice. An astronaut who is bored might simply withdraw, disengage, start making small errors. The behavioural drift is gradual. By the time anyone names it, the damage to crew cohesion and task performance can be significant.

I’ve seen the same pattern in non-space contexts. A person who is bored in their marriage doesn’t usually acknowledge the boredom directly. They say “I’m fine.” Then they pick up a new hobby, start working longer hours, spend more time online. The boredom drives behaviour change without ever being consciously acknowledged as the driver.

Why We Fear the Signal

There’s a reason we medicate boredom so reflexively. Boredom, if you actually stay with it, asks uncomfortable questions.

Am I doing meaningful work? Does this relationship still serve me? Have I been coasting? Am I living according to my values or according to inertia?

These are not comfortable questions. They threaten stability. They imply that change might be necessary, and change is expensive in every sense: emotional, financial, relational. It’s genuinely easier to open Instagram.

Research on achievement emotions and learning performance confirms that boredom doesn’t just reduce engagement. It actively degrades the quality of whatever you’re doing. People who are bored don’t just do less. They do worse. Their cognitive processing becomes shallow. Their memory formation weakens. They take shortcuts.

The parallel to life outside a classroom is exact. A bored employee doesn’t just produce less output. They produce worse output, make more errors, and gradually stop caring about the difference. A bored partner doesn’t just spend less time with you. They become less present when they’re there.

Investigation Over Medication

What does it actually look like to investigate boredom rather than medicate it? In the isolation research I’ve done, and in my own life, it starts with the smallest possible intervention: pausing before reaching for the antidote. When boredom shows up, the window between feeling it and medicating it is tiny. Sometimes less than a second. Widening that window even slightly, even to five or ten seconds, creates space for the signal to register. What do I actually need right now? Often the answer is not more stimulation but rather connection, challenge, rest, or something meaningful.

That pause, if you can hold it, opens a second question: what kind of boredom is this? Researchers have identified at least five distinct varieties, from indifferent boredom (low arousal, almost pleasant) to reactant boredom (high arousal, actively searching for alternatives). They don’t all mean the same thing and they don’t all require the same response. Indifferent boredom might be a sign that you need rest. Reactant boredom might mean you’ve outgrown something and need a new challenge. Treating all boredom as the same undifferentiated state that needs to be eliminated is like treating all pain with the same dose of the same painkiller. I watched a crew commander in a 120-day simulation realise, through exactly this kind of differentiation, that his afternoon restlessness wasn’t a need for more tasks — it was a need for creative autonomy, for something that wasn’t pre-scripted by mission control. Once he named it correctly, the solution was obvious. Before that, he’d been filling the gap with busywork that left him more drained than the boredom itself.

And this is where investigation gets genuinely difficult. Because once you’ve paused long enough to feel the boredom, and listened carefully enough to identify what it’s actually about, you arrive at a third and harder stage: being willing to act on what the investigation reveals. If your boredom at work is telling you that you’ve stopped growing, the investigation might lead you to an uncomfortable conclusion about your career. If your boredom in a relationship is telling you that you’ve substituted routine for intimacy, the investigation might lead to a difficult conversation. Boredom’s signal often points toward action that is costly in the short term and valuable in the long term. Most people stall here. They hear the signal, understand it, and then medicate anyway — because the cost of responding honestly feels too high. That’s not a failure of awareness. It’s a failure of courage, and I include myself in that category more often than I’d like to admit.

What Depression Taught Me About Boredom

I should be honest about something. Spending fifteen years studying the psychology of isolation and adaptation didn’t protect me from struggling with my own mental health. When I went through a significant period of depression in my early fifties, one of the things I noticed was how much it resembled chronic boredom. The flatness. The sense that nothing quite connected. The inability to feel interested in things I knew, intellectually, I cared about.

My therapist pointed out something that should have been obvious to someone with my background but wasn’t: I was treating the depression the same way I’d watched crews treat boredom in isolation. I was trying to solve it. Fill the gap. Stay busy. Produce more. And none of it worked, because the signal wasn’t asking for more activity. It was asking for something deeper, something about meaning and connection and the gap between the life I was living and the life I needed.

Intellectual knowledge of a psychological process doesn’t prevent you from being caught by it. That’s a humbling lesson I carry into every piece I write. Knowing about boredom, knowing exactly what it does to cognition and behaviour and crew dynamics, does not make you immune to medicating it the moment it appears in your own life. The researcher and the subject are, in the end, the same species — equally prone to flinching away from signals that demand more than a quick fix.

The Broader Pattern

We live in a culture that has made boredom almost impossible to experience fully. The phone is always within reach. Streaming services auto-play the next episode. Notifications arrive constantly. The infrastructure for medicating boredom is so efficient that many people haven’t truly sat with the feeling in years.

Research examining academic burnout and problematic smartphone use has found that the relationship between burnout and excessive phone use appears to be strengthening over time, with stronger associations in more recent years. The tools for boredom-medication are getting better, faster, and more available. The gap between feeling bored and eliminating the feeling is shrinking toward zero.

That sounds like progress. It isn’t.

Every time you eliminate boredom before it can deliver its message, you lose information about yourself. About what you need, what you value, what’s working and what isn’t. Boredom is your internal compass trying to recalibrate, and we keep smacking it off the dashboard because the needle is moving in an uncomfortable direction.

In spaceflight, we take boredom seriously because the consequences of ignoring it are severe. A crew that can’t process boredom productively on a three-year Mars mission will fracture. We design countermeasures, build psychological support tools, train crews to recognise the signal and respond to it rather than suppress it.

On Earth, we do the opposite. We build better suppressants.

What the Signal Is Actually Saying

If you’re chronically bored, the signal might be telling you that you’ve stopped challenging yourself. That you’re in an environment where your abilities aren’t being used. That a relationship has gone stale. That you’ve been coasting on routine. That something you once found meaningful has lost its connection to your deeper values.

These are not small messages. They are directional cues for how to live a life that fits.

Research on emotional perception and cognitive processing shows that people in negative emotional states process information differently, often with reduced depth and weaker integration. When boredom becomes chronic, it doesn’t just make you feel flat. It changes how you think, how you perceive your options, how you evaluate your own life. The longer you medicate instead of investigate, the harder it becomes to hear the signal at all.

The astronauts who handle long-duration missions best aren’t the ones who never get bored. They’re the ones who treat boredom as data. They notice it, name it, and ask what it means. Then they respond to the meaning, not just the feeling.

That capacity, which sounds simple and is extraordinarily difficult in practice, is one of the most important psychological skills we can develop. Not just for space. For everything.

Boredom is trying to tell you something. The question is whether you’ll listen before reaching for the nearest distraction. Most people won’t. But the ones who do tend to make better decisions about their lives, their work, and their relationships. Because they’re working with a signal that the rest of us keep silencing before it finishes its sentence.

Lebedev, in his diary, eventually stopped fighting the monotony aboard Salyut 7. He started writing more, observing more, turning his attention inward in ways that the mission planners hadn’t scheduled. He didn’t eliminate the boredom. He let it redirect him. The diary itself — one of the most detailed psychological records we have of long-duration spaceflight — was the product of a man who chose investigation over medication.

You probably don’t live on a space station. But tonight, when the feeling arrives — and it will — you have the same choice he did. Reach for the antidote, or sit with the signal long enough to hear what it’s actually saying. The answer won’t always be comfortable. It might point toward a change you’ve been avoiding for months or years. But it will be yours, which is more than the algorithm on the other side of that glowing rectangle can offer you.
