Most of us are familiar with the feeling of a mind that refuses to stay put. While we are folding laundry, sitting in a meeting, or jogging through a park, our thoughts often drift away from the present moment. Usually, this drift is cognitive—we replay an argument from three years ago, plan next week’s grocery list, or imagine a conversation we haven’t had yet.
However, new research suggests that mind wandering to physical sensations—a phenomenon scientists call “body wandering”—operates differently in the brain and may have a distinct impact on our emotional well-being. According to a study published March 25 in Proceedings of the National Academy of Sciences (PNAS), the act of spontaneously noticing one’s own heartbeat, breath, or the pressure of clothing against the skin can influence both immediate mood and long-term mental health.
For years, the study of mind wandering has focused primarily on the “cognitive” side: the memories, social interactions and future-planning that occupy our internal monologue. While this type of mental drifting is essential for creativity and learning, it has a darker side. When cognitive wandering turns into rumination—obsessively dwelling on past mistakes—it is frequently linked to higher rates of depression and attention-deficit/hyperactivity disorder (ADHD).
The new findings from neuroscientists at Aarhus University in Denmark suggest that body wandering may provide a different, and perhaps more grounding, alternative to these cognitive loops.
The Brain Signature of Body Wandering
To understand the difference between thinking about a memory and feeling a heartbeat, Micah Allen and his colleagues monitored 536 participants using magnetic resonance imaging (MRI). While lying still in the scanner, participants experienced spontaneous shifts in attention. Afterward, they completed questionnaires detailing where their minds had traveled.
The researchers discovered that body wandering is not simply a subset of general mind wandering. The MRI scans revealed a distinct brain signature for those focusing on internal physical sensations—such as the rhythm of their breathing or the state of their bladder—compared to those engaged in cognitive daydreams. This suggests that the brain utilizes different neural pathways when it shifts attention inward toward the soma rather than outward toward a thought or memory.
The Paradox of Mood and Mental Health
The study revealed a complex relationship between body focus, and emotion. In the short term, participants who reported more body wandering were more likely to experience negative emotions during their time in the MRI scanner. Study coauthor Leah Banellis noted that this specific negative experience might be amplified by the enclosed, restrictive environment of the MRI machine.
However, this immediate emotional dip does not notify the whole story. When looking at long-term mental health markers, the results shifted. Participants who tended to engage in body wandering more frequently overall reported fewer symptoms of depression and ADHD.
This suggests a protective mechanism linked to interoception—the body’s ability to sense and interpret internal signals. While cognitive rumination can pull a person deeper into a depressive state, the ability to connect with physical sensations may act as a stabilizer. By shifting focus from a distressing thought to a physical reality—like the feeling of breath moving in and out—the mind may identify a way to break the cycle of negative thinking.
Comparing Cognitive vs. Somatic Mind Wandering
| Feature | Cognitive Wandering | Body Wandering (Somatic) |
|---|---|---|
| Primary Focus | Memories, plans, social events | Heartbeat, breath, internal organs |
| Neural Pathway | Cognitive-specific brain signature | Distinct interoceptive signature |
| Mental Health Risk | Linked to rumination and depression | Associated with fewer ADHD/depression symptoms |
| Immediate Effect | Can be neutral or highly distressing | May cause immediate negative mood in confined spaces |
Critical Limitations and Future Directions
Despite the promising results, some experts urge caution in how the data is interpreted. Aaron Kucyi, a neuroscientist at Drexel University in Philadelphia who peer-reviewed the study, pointed out a significant limitation: participants were asked to recall their thoughts only once, after the entire session was over.
Because mind wandering is dynamic and varies from moment to moment, a single post-session summary may miss the nuances of how attention shifts in real-time. “A cross-section, single measure that tries to summarize all their experience in that time could be missing out on the nuances,” Kucyi noted.
Daniel Smilek, a neuroscientist at the University of Waterloo, echoed the need for more diverse settings. While the MRI scanner provided a controlled environment, examining how people “body wander” during daily chores or high-stress work tasks would provide a more complete picture of how this process affects our daily lives.
Nevertheless, the research marks a pivotal step in integrating the study of interoception with the study of mind wandering. By understanding how to consciously or spontaneously shift attention from a cognitive loop to a physical sensation, clinicians may be able to develop new grounding techniques for patients struggling with anxiety, ADHD, or chronic rumination.

The research community is now looking toward longitudinal studies that use real-time tracking—such as smartphone-based experience sampling—to see if increasing interoceptive awareness can actively reduce symptoms of depression over time.
