Mindfulness meditation is often presented as a relaxation technique. Yet, it touches on something more fundamental: our capacity to fully inhabit our experience. Neuroscience shows that meditation influences not only the brain, but also the entire body and nervous system. This article explores the role of presence, attachment, and inner security in our ability to calm ourselves and be present with ourselves.
Long associated with well-being or contemplative traditions, mindfulness is now the subject of much research in neuroscience. This research shows that meditation can modify attention, emotional regulation, and the activity of certain brain networks. But it also influences breathing, bodily tension, heart rate, and, more broadly, our sense of inner security.
Why do some people quickly experience a sense of calm, while others feel overwhelmed by their thoughts or anxiety as soon as they close their eyes? Contemporary neuroscience, polyvagal theory, and trauma-focused approaches now offer new perspectives on these questions. Perhaps meditation isn't simply about "emptying the mind," but about gradually rediscovering a more stable way of inhabiting one's attention, one's body… and presence in the world.
A brain that never stops
Just a few years ago, mindfulness meditation was often seen as a fringe practice, associated with personal development or certain Eastern spiritual traditions. Today, it's everywhere: mobile apps, businesses, hospitals, psychotherapy, neuroscience. This interest is not insignificant. It likely reflects a reality that many people recognize: that of a mind that seems never to stop, often accompanied by a body that also remains in a state of alert. Intrusive thoughts, pervasive anxiety, mental fatigue, physical tension, difficulty being truly present in the moment.
In this context, meditation is appealing because it offers something seemingly very simple: returning to immediate experience. Breathing. Observing. Feeling. Being present. But behind this simplicity lies something much deeper.
What happens in the brain when we meditate
For a long time, meditation was described primarily in philosophical or spiritual terms. Neuroscience has gradually allowed us to observe what happens in the brain when a person practices mindfulness. It also shows that these changes are accompanied by broader modifications throughout the body: calmer breathing, a reduction in certain bodily tensions, and better regulation of the autonomic nervous system.
When attention stabilizes on the breath, bodily sensations, or the immediate environment, several phenomena seem to occur: a decrease in mental agitation, a reduction in certain forms of rumination, better emotional regulation, and sometimes a feeling of inner slowing down. In other words, meditation is not simply about "thinking positively." It alters the state of the nervous system and, more broadly, the way the body and mind respond to their environment.
Some people then discover something surprising: they spend a large part of their lives disconnected from their own immediate experience. The body is there, but the mind is elsewhere—in anticipations, scenarios, worries, memories, or daily obligations. Mindfulness offers precisely this approach: returning to this direct experience—not to eliminate thoughts, but to no longer be entirely swept away by them.
Why are some people unable to meditate?
This is probably one of the biggest misconceptions about meditation. Some people close their eyes for a few minutes and immediately experience a surge of anxiety, inner turmoil, uncontrollable thoughts, even difficult memories or a feeling of emptiness. They then conclude that they are "not cut out for meditation." In reality, it's most often not a matter of willpower.
The human nervous system doesn't calm down simply because it's asked to. In some people—particularly those experiencing chronic stress, hypervigilance, psychological trauma, insecure attachment, or emotional exhaustion—the body remains in a near-constant state of alert. In this state, stillness and silence can paradoxically become difficult to tolerate.
The polyvagal theory, developed by neuroscientist Stephen Porges, offers valuable insight here. It describes how the autonomic nervous system constantly assesses the environment for signals of safety or danger—a process called neuroception, which operates outside of any voluntary awareness. Before it can calm down, the nervous system must first perceive sufficient safety. And sometimes, this safety cannot be found on its own.
This observation aligns with a central idea of the Presence Brain: we rarely learn to calm ourselves alone. Before we can find calm on our own, we generally discover it in the presence of others. Infants borrow the nervous system of their caregivers; children gradually learn to regulate themselves through thousands of co-regulatory experiences. Before self-regulation, there is often shared regulation. For some people, meditating alone is like asking their body to rediscover a state it has never truly learned to achieve on its own.
In these situations, difficulty meditating is not a failure — it sometimes constitutes valuable information about the history of the nervous system.
Is meditation really a solitary experience?
Meditation is often presented as a purely internal, individual practice, almost isolated from the social world. Yet, neuroscience shows that the brain—and more broadly, the entire organism—remains profoundly sensitive to the presence of others, even without direct interaction. The mere presence of another person can alter our alertness, our stress level, our breathing, our heart rate, and the activity of certain major brain networks. In other words, we never function completely alone.
In certain situations, meditating in the presence of a group, a therapist, or simply a calm and reassuring person can profoundly transform one's inner experience. Many patients describe it very simply: "I can't do it alone. But when someone is there, something calms down."
This observation points to something fundamental. What helps some people meditate may not be just the technique itself, but the quality of presence in which this experience becomes possible. Co-regulation—the process by which one person's nervous system can calm itself through contact with another's—often precedes, and sometimes conditions, any lasting self-regulation.
Meditation, psychotherapy, and addictions
This perspective is particularly useful for understanding certain addictions. Alcohol, cannabis, screens, food, work, or certain compulsive behaviors can sometimes be understood as attempts at appeasement: they provide temporary relief, a reduction in tension, or a momentary interruption of suffering.
When someone begins to meditate, they sometimes find themselves directly confronted with what these strategies had previously helped them avoid: inner turmoil, anxiety, loneliness, painful emotions, or physical discomfort. The difficulty then lies not in the fact that meditation doesn't work—it's that it reveals precisely what the addiction was helping to keep at bay. In this context, mindfulness can help to gradually develop a different relationship with sensations, emotions, and impulses.
But this work is often made easier when it takes place in a sufficiently safe human environment.
Meditation, psychotherapy and emotional regulation
In the field of psychotherapy, mindfulness now occupies an important place, particularly in approaches focused on trauma, anxiety, addictions, or emotional regulation. But therapeutic meditation is not about asking someone to "stay calm." Rather, it aims to help them gradually reconnect with their bodily experience, observe their emotions without being overwhelmed by them, develop a different relationship with their thoughts, and regain a sufficient sense of inner security to inhabit the present without immediate danger.
In approaches like EMDR, mindfulness can also help stabilize attention, strengthen internal resources, and maintain a connection to the present moment during therapy. But this requires gradual progression, a steady pace—and a therapeutic relationship that is safe enough for the nervous system to allow itself to let its guard down.
When meditation is not enough
Meditation can be valuable. But it's not a one-size-fits-all solution. What's sometimes called "difficulty meditating" often reflects an exhausted nervous system, chronic hyperarousal, old relationship wounds, or a habitual survival mode. In these situations, the goal isn't to "meditate better": it's primarily to regain enough security so that the body can release some of its vigilance.
This path often involves the body, relationships, and the quality of human presence around oneself—even before resorting to any technique. Co-regulation, the therapeutic bond, and attention to breathing in a safe space are all ways in which the nervous system can gradually emerge from a state of chronic mobilization.
Another way to understand mindfulness
Perhaps mindfulness is not ultimately an attempt to "empty the mind." Perhaps it corresponds to something simpler and more fundamentally human: rediscovering a more stable way of inhabiting one's body, one's attention, and presence in the world.
In this sense, meditating is not about isolating oneself from the world to find peace. It is about learning, gradually, to be present — to oneself, to others, and to the living experience of the moment.
The human brain develops in presence. So does the body. And it is often in presence that the organism gradually regains the capacity to be fully present to itself.
