Pacing while talking on the phone is your brain recruiting your body to help process conversation. When you’re on a call, you lose all the visual information you’d normally get from a face-to-face chat: facial expressions, body language, eye contact. Your brain compensates by channeling that unoccupied processing power into physical movement, which actually helps you think, speak, and listen more effectively.
Your Brain Links Speech and Movement
Speech and physical movement share real estate in the brain. A region in the premotor cortex, the area responsible for planning and coordinating movement, activates during both speech production and speech perception. This region sits right between the parts of the brain that control hand movement and mouth movement, creating a natural bridge between talking and moving your body.
This overlap means that when your brain ramps up verbal processing, it simultaneously nudges your motor system into action. During a phone call, you’re both producing speech and working harder than usual to interpret what you’re hearing without visual context. That heightened verbal processing spills over into your motor cortex, and the result is movement: pacing, gesturing, tapping your fingers, or wandering from room to room without realizing it.
Phone Calls Create Extra Cognitive Work
In person, roughly half the information in a conversation comes from nonverbal cues. On the phone, all of that disappears. Your brain has to work harder to decode tone, fill in emotional context, and track the flow of conversation using sound alone. Psychologists describe this as your brain needing “physical movement to process real-time verbal conversation at full capacity,” a process sometimes called motor recruitment.
Think of it this way: in a face-to-face conversation, you can glance at someone’s expression to confirm they understood you, or notice their body language shifting before they even speak. On the phone, your brain is doing all that interpretive work internally, and it uses movement as a release valve. Walking frees up mental space to process what you’re hearing and formulate your response at the same time. People who pace while on calls are essentially giving their brain an outlet so it can focus more fully on the conversation itself.
This also explains why you’re less likely to pace during a video call. When you can see the other person, your brain gets enough visual data to stay settled. Remove the video feed, and the pacing often starts right back up.
You Still Gesture Even When No One Can See You
Here’s something interesting: people don’t just pace on the phone. They also gesture with their hands, nod, and make facial expressions, even though the person on the other end can’t see any of it. Research published in the Journal of Memory and Language found that while people gesture less when their conversation partner isn’t visible, the rate never drops to zero. You keep gesturing regardless.
One explanation is simply habit. You’ve spent your entire life pairing speech with movement in face-to-face settings, and your brain doesn’t fully switch that off just because the audience is invisible. But there’s a deeper explanation rooted in embodied cognition, the idea that thinking isn’t something that happens only in your head. Your brain uses the same systems for thinking about the world that it uses for physically experiencing it. Gesturing and moving aren’t just byproducts of conversation. They’re part of how your brain constructs and organizes what you want to say.
Emotional Energy Needs Somewhere to Go
Phone calls also create a unique emotional bottleneck. In person, emotional energy flows back and forth naturally between two people through shared glances, nods, and physical proximity. On the phone, you’re absorbing all the emotional content of the conversation without that physical exchange. As one psychologist put it, it’s like juggling a hot potato with no one to pass it to.
Pacing becomes the physical outlet for that trapped energy. It activates your sympathetic nervous system just enough to burn off the low-level arousal that builds during a call, whether the conversation is stressful, exciting, or even routine. This is why you might notice yourself pacing more during emotionally charged calls and sitting still during mundane ones. The more your brain has to process emotionally, the more your body wants to move.
ADHD and Neurodivergence Can Amplify It
If you pace constantly during phone calls and find it nearly impossible to sit still, it may be connected to how your brain is wired. For people with ADHD, pacing is a recognized form of self-stimulatory behavior, often called stimming. It falls into the category of vestibular (balance-based) stims, alongside rocking, leg shaking, and spinning. These repetitive movements help people with ADHD improve focus, manage impulse control, and channel excess energy that might otherwise become distracting.
Autistic individuals also commonly pace as a way to cope with sensory input, relieve anxiety, or process intense thoughts. The function is slightly different: where ADHD-related pacing tends to sharpen focus, autistic pacing more often serves as a soothing mechanism or a way to shut out overwhelming external stimuli. In both cases, the movement is doing real cognitive work, not just burning off restlessness. If pacing during phone calls is part of a broader pattern of needing movement to concentrate or regulate your emotions, it could be worth exploring whether ADHD or autism is part of the picture.
Movement and Communication Evolved Together
Humans didn’t evolve to sit still while communicating. For most of our species’ history, communication happened while moving: walking, foraging, working with tools, scanning for threats. Research on the co-evolution of language and gesture suggests that human communication likely began with physical gestures before spoken language fully developed. Our hominin ancestors evolved as cooperative foragers who needed to coordinate with each other while physically manipulating their environment, and communication was essentially a special case of collective physical action.
That evolutionary history is still embedded in your nervous system. Sitting motionless in a chair while having an intense conversation is actually the unnatural state. Pacing during a phone call is closer to the default mode your brain expects during verbal communication.
A Small Physical Benefit Too
There’s a practical upside to all this involuntary walking. Pacing during phone calls counts as non-exercise activity thermogenesis, or NEAT, the calories your body burns through everyday movements that aren’t formal exercise. Harvard Health specifically lists pacing during phone calls as one way to increase NEAT throughout the day. Research from the Mayo Clinic found that NEAT can vary by up to 2,000 calories per day between two people of similar size, and that leaner individuals tend to stand or walk more than two hours longer each day than those who are more sedentary. If you spend 30 to 60 minutes on calls each day, that pacing adds up over weeks and months.
So the next time you catch yourself doing laps around your kitchen during a call, there’s no reason to fight it. Your brain is doing exactly what it’s designed to do: using your body to think better.
