Psychology says talking to yourself when you’re alone isn’t a sign of loneliness; it’s one of the brain’s smartest tools for regulating emotion and rehearsing decisions

You're rinsing a coffee mug, and you hear yourself say, aloud, "Wait, where did I put my keys?” A coworker walks by, and you feel a flash of embarrassment, like you just got caught doing something a little unhinged. Here's the good news: you didn't. According to a 2025 study published in Scientific Reports, researchers tracked 208 adults for two weeks, collecting some 13,000 daily survey responses about more than 20,000 individual moments. In 61 percent of the situations researchers asked about, people reported talking to themselves, silently or out loud. Only 1 percent said they never did this. So if you whisper your grocery list to yourself or give yourself a pep talk in the mirror, you are in the overwhelming majority, not the outlier.

This habit goes back to childhood
Watch a toddler stacking blocks, and you will hear a running commentary, "this one goes here, no, not like that. According to the foundational work of psychologist Lev Vygotsky, this kind of out-loud narration in young kids, which he called private speech, is associated with children learning to plan and control their own behavior. As we grow up, a lot of that narration turns inwards and becomes what we call thinking, but it never really goes away, which is why an adult may suddenly start muttering directions when parallel parking.

Why your car and shower turn into thinking rooms
There’s a reason why so much self-talk happens in certain places: the car, the shower, a solo walk, folding laundry. Your hands are busy with something familiar; no one is watching, and there is no screen competing for attention. Now that the social pressure is off, the brain can finally complete a sentence it couldn't finish at your desk.

The alarm stops when you name the feeling
There’s a reason why saying out loud, “I’m anxious about this presentation,” can actually help. According to research from UCLA psychologist Matthew Lieberman and colleagues, published in Psychological Science, putting a feeling into words reduced activity in the amygdala, the brain’s threat detector, and increased activity in a prefrontal area associated with emotional regulation. The study suggests that putting a name to an emotion can help the brain dampen its own alarm system, almost like turning down the dimmer switch on a feeling that is running too hot.

The trick athletes and CEOs use on purpose
But researchers say there is one form of self-talk that can be more effective for dealing with stress: replacing ‘I’ with your own name. A 2017 study from Michigan State University and the University of Michigan, published in Scientific Reports, showed that when people thought about stressful situations using their own name or the word "you" instead of "I", they had less brain activity related to emotional distress, and they didn’t have to try any harder to get there. A runner saying to herself, "Jess, you've trained for this," before a race is not being quirky; she is using a documented shortcut to emotional distance.

Saying it out loud can rearrange the thought
Most adults have experienced the feeling of working on a problem for hours, explaining it to a friend, and arriving at the answer mid-sentence, even if the friend didn’t say much. Self-talk can be like that, without an audience. According to the same 2025 Scientific Reports study, self-talk was most often used by people when they needed to prepare what to say or do next, and employing a more distanced, name-based style in those particular moments was associated with feeling significantly better in that moment, but the same boost didn’t show up across all types of situations.

Some self-talk fails to do its job
This is important because not all inner narration works in the same way. Helpful self-talk moves you somewhere, names a feeling, breaks a task into steps, or practices what to say next. The unhelpful version gets stuck on repeat, replaying, "I cannot believe I said that" without actually getting anywhere new. This dataset also found that people relied on this repetitive, immersive style far more than the distanced kind. However, the distanced kind was associated with feeling better in moments that called for preparation.

When it is worth paying attention
None of this means that self-talk is necessarily healthy in all forms. Talking to yourself aloud is a normal and often useful habit, the Cleveland Clinic says, one that can even help you focus better on a task. The exception is when hallucinations drive the speech; that is, it feels like a response to a voice coming from outside your own head. That is a totally different phenomenon and worth mentioning to a doctor.

So next time you’re trying to negotiate with your reflection or giving the dishwasher a stern talking to, you don’t need to look around to see who’s listening. Your brain isn’t broken; it’s reaching for one of the oldest, cheapest tools it has.
