Summary: A study published in Biological Psychiatry shows that mindfulness meditation reduces pain through distinct brain mechanisms, separate from the placebo effect, and may offer an effective, drug-free intervention for pain management.

Key Takeaways

  • Distinct Brain Mechanisms: Brain imaging revealed that mindfulness meditation uses different brain processes than the placebo effect to reduce pain, showing it works through distinct neural pathways.
  • Reduced Pain-Related Brain Activity: Mindfulness meditation significantly decreased brain activity linked to pain intensity, unpleasantness, and negative emotions, while the placebo cream only reduced activity related to the placebo response.
  • Altered Brain Synchronization: Mindfulness meditation reduced synchronization in brain areas involved in self-awareness and emotional regulation, suggesting it alters the neural pain signal more effectively than placebo or sham interventions.

Pain is influenced by more than just physical sensation—factors like mindset and expectations play a major role. The placebo effect, where symptoms improve with inactive treatment, shows how expectations shape pain. Mindfulness meditation, long used for pain management, was thought to trigger the placebo response. However, new research shows otherwise.

Pain Relief via Unique Brain Mechanisms

A study published in Biological Psychiatry reveals that mindfulness meditation uses distinct brain mechanisms to reduce pain, separate from the placebo effect. Researchers at UC San Diego used brain imaging to compare the pain-relief effects of mindfulness meditation, placebo cream, and a sham meditation in healthy participants.

Results showed mindfulness meditation significantly reduced pain intensity and unpleasantness, as well as brain activity related to pain and negative emotions. In contrast, the placebo cream only reduced brain activity tied to the placebo response without changing the actual pain experience.

“The mind is powerful, and we’re learning how to harness it for pain management,” says Fadel Zeidan, PhD. “Mindfulness meditation changes how we experience pain without drugs or cost—it can be practiced anywhere.”

Inside Brain Scan Research

The study included 115 participants across two clinical trials. Participants were randomly assigned one of four interventions: guided mindfulness meditation, sham meditation (deep breathing), placebo cream (petroleum jelly), or an audiobook. Pain was induced via a painful but harmless heat stimulus, and brain scans were taken before and after.

Researchers used a machine-learning technique called multivariate pattern analysis (MVPA) to examine brain activity patterns associated with pain, negative emotions, and placebo responses. Mindfulness meditation was found to be more effective at reducing pain than placebo cream or sham meditation, engaging different brain processes.

Mindfulness meditation also reduced synchronization in brain areas involved in self-awareness and emotional regulation, which are part of the neural pain signal (NPS). This was not seen in placebo or sham interventions, suggesting distinct brain mechanisms.

“It was believed the placebo effect overlaps with active treatments, but our findings show mindfulness and placebo engage separate brain responses,” says Zeidan. “This supports mindfulness meditation as a direct intervention for chronic pain, not just a placebo.”

While mindfulness outperformed placebo in this study, more research is needed to confirm these effects in people with chronic pain. The researchers hope to develop more effective, accessible treatments using mindfulness. “Millions live with chronic pain, and there may be more they can do to reduce it than we previously thought,” says Zeidan. “We’re excited to continue exploring how mindfulness can improve pain management.”
