Expert Meditators Can Dissolve Their Sense of Self. Their Brains Also Learn to Change Pain.

Evidence review & editorial synthesis

Your sense of being a separate person inside a body feels less like something your brain does than something that simply exists. Pain can feel equally non-negotiable: a signal arrives, and you hurt.

Research on highly experienced meditators is beginning to challenge both intuitions. In a new brain-imaging study, meditators deliberately weakened their sense of being a bounded self while remaining conscious, producing a measurable neural signature. Other experiments suggest that extensive meditation training can also change how pain reaches conscious experience and, in specialized practices, even influence body temperature.

The provocative implication is not that thought can magically control the body. It is that the border between voluntary and involuntary processes may be less rigid than it seems.

Experienced meditators could deliberately turn down the sense of self

The new study examined 45 long-term meditators who had accumulated an average of 3,832 hours of practice.

Inside a magnetoencephalography scanner, they moved between ordinary rest, actively maintaining their normal sense of self, and a meditative state in which the boundaries separating self from world weakened or dissolved.

Previous work from the same research program helps explain how unusual that experience can become. Participants described alterations in body boundaries, self-location, agency, first-person perspective and the distinction between themselves and the surrounding world, while remaining awake and aware.

This matters because consciousness and selfhood often feel inseparable. We assume that being conscious necessarily means experiencing the world from inside a clearly defined 'me.' These meditators provide a rare experimental way of separating the two.

Their brains did not simply become globally quieter or more chaotic. Meditation broadly increased neural entropy and information transfer, while self-dissolution produced selective reductions in specific circuits, including cingulate, posterior-medial, limbic, subcortical and orbitofrontal regions.

Combined neural measures explained 52% of the differences in how deeply participants reported their sense of self dissolving. Most intriguingly, reduced information transfer still predicted dissolution in participants left out of the original model.

That raises a remarkable possibility: what feels like the most basic fact of existence, the experience of being a separate self, may depend on continuously maintained brain processes that can be deliberately reconfigured.

Pain reveals another layer of trainable control

Selfhood is abstract. Pain is not.

Yet pain research in expert meditators points toward a similar idea: the brain may have more freedom over the final experience than the incoming signal suggests.

In one fMRI experiment, meditators with more than 10,000 hours of practice were exposed to painful heat alongside inexperienced controls. The experts did not simply stop detecting the stimulus. They reported roughly comparable pain intensity but significantly less unpleasantness.

That distinction is profound.

Pain is not one thing. There is the sensory event, how intense it feels, the anticipation before it arrives, the emotional reaction to it and the urge to escape it. Meditation appeared capable of separating some of those layers.

Experienced practitioners also showed less anticipatory activity before pain and faster neural habituation. In practical terms, the body could still say 'this hurts' without the mind adding as much 'this is terrible and I need it to stop.'

Another experiment made the finding stranger. Researchers gave 32 experienced meditators naloxone, a drug that blocks opioid receptors, in a randomized double-blind crossover design. If meditation analgesia simply depended on the body's natural opioid system, blocking those receptors should have weakened it.

It did not.

Meditation still reduced pain, and naloxone actually strengthened the analgesic effect. During saline sessions, pain unpleasantness fell from 4.96 to 3.98 during meditation. Under opioid blockade it fell further, to 2.95.

Among the initial group screened for the experiment, 85% showed at least a 15% meditation-related reduction in pain intensity or unpleasantness.

The implication is not that meditation is a replacement for analgesic medication. It is that the brain appears to possess non-opioid routes for changing the experience of pain that can become accessible through training.

Years of practice may alter pain before conscious interpretation

A 2025 EEG study pushed that idea further.

Researchers compared long-term and less experienced meditators while delivering painful stimuli outside active meditation. In the experienced group, pain-related neural synchronization was already suppressed in primary and secondary somatosensory areas within roughly the first 200 milliseconds after the stimulus.

That is extremely early.

It suggests that years of practice may do more than teach someone to reinterpret pain after it arrives. Training may alter the brain's habitual processing of nociceptive information close to the beginning of the cortical response.

This is where meditation research becomes more interesting than the familiar claim that relaxation makes people feel better. If replicated, it implies neuroplasticity can change how the nervous system processes an aversive signal before the person has consciously constructed the full emotional experience around it.

For chronic pain research, that possibility is important. Chronic pain frequently involves amplification, prediction, attention and emotional learning in addition to signals from injured tissue. Learning how expert brains decouple those components could eventually help researchers design more targeted non-drug pain interventions.

Some practitioners can even change body temperature

The limits of trainable control may extend beyond subjective experience.

Researchers studying practitioners of g-Tummo, a Tibetan contemplative practice combining forceful 'vase' breathing with visualization, recorded reliable increases in axillary body temperature.

During the full practice, some experienced meditators moved from normal temperature into the mild-to-moderate fever range, with a maximum measured temperature of 38.3 degrees Celsius. Breathing alone produced smaller increases, while meditative visualization appeared to help practitioners sustain the rise.

That does not mean ordinary meditation lets someone turn body temperature up like a thermostat. G-Tummo is a specialized technique, the studies were small, and vigorous breathing itself contributes to heat production.

But it demonstrates something important: deliberate mental and respiratory training can reach physiological systems that most people rarely experience as consciously controllable.

The bigger question is where voluntary control actually ends

None of these findings show that meditation can magically repair organs or cure serious disease. That leap would go far beyond the evidence.

What they do reveal is arguably more scientifically interesting.

The sense of self can be weakened while awareness remains. Pain can be uncoupled from some of its unpleasantness. Long-term practice appears to alter very early neural responses to painful input. Opioid blockade does not eliminate meditation analgesia. A specialized contemplative practice can measurably raise body temperature.

Taken together, these observations challenge a simple division between voluntary mental activity and automatic bodily function.

Humans clearly cannot think their way into complete control of physiology. But expert meditators may provide an unusual demonstration of what thousands of hours of neuroplastic training can do to systems that normally seem untouchable.

The most interesting question may therefore be less mystical than it first appears: how much of what we call an automatic human experience is automatic only because we have never learned how to change it?
