Khaberni - Researchers at the University of California have discovered that a one-week program that combines meditation with other mind-body techniques can quickly bring about tangible changes in both brain activity and blood composition.
The study showed that these practices activated natural pathways responsible for brain resilience, metabolism, immune function, and pain relief, according to Science Daily citing the journal Communications Biology.
The results also provided new evidence that mental practices can significantly impact physical health.
Ancient Methods
Meditation and similar techniques have been used for thousands of years to support health, but scientists have struggled to accurately explain how they affect the body.
The new research, part of a large-scale initiative funded by the InnerScience Research Fund, is the first of its kind to systematically measure the combined biological effects of multiple mind-body techniques applied over a short period.
Change in Biological Systems
The lead researcher of the study, Himal Patel, who is a professor of Anesthesiology at the University of California's Medical School and a scientific researcher in the healthcare system for veterans in San Diego, said: "We have known for years that practices like meditation impact health, but what is remarkable is that integrating multiple mind-body practices in one retreat has created changes across several biological systems to a degree that we could directly measure in the brain and blood."
Patel also explained that "It's not just about reducing stress or relaxation, but about a radical change in how the brain interacts with reality, and measuring these biological changes."
Among the effects are stress relief or relaxation and a radical change in how the brain interacts with reality, and measuring these changes biologically within the 7-day meditation program.
"Open Placebo Therapy"
The study followed 20 healthy adults who participated in a 7-day residential retreat led by Joe Dispenza, a doctor of chiropractic medicine, a teacher in neuroscience, and an author. Participants attended lectures and completed about 33 hours of guided meditation, in addition to group therapeutic activities.
The sessions employed an "open placebo" approach, meaning the participants were aware some of the practices were presented as placebo treatments. Nevertheless, such interventions were still capable of producing real effects through expectation, shared experience, and social interaction.
Before and after the retreat, the researchers used functional MRI (fMRI) imaging to monitor brain activity. Blood samples were also analyzed to track changes in metabolism, immune function, and other biomarkers.
Notable Changes
Several remarkable changes were observed after the retreat:
• Changes in brain networks: Activity decreased in areas associated with internal mental chatter, indicating improved brain function efficiency.
• Enhanced neuroplasticity: Plasma collected after the retreat stimulated lab-cultured neurons to stretch and form new connections.
• Metabolic shifts: Cells exposed to post-retreat plasma showed an increase in glucose metabolism, indicating improved metabolic resilience.
• Natural pain relief: Levels of endogenous opioids, the body's natural pain relievers, increased after the retreat.
• Immune activation: Both inflammatory and anti-inflammatory signals increased, indicating a balanced and adaptive immune response.
• Changes in genetic and molecular signals: Activity of small ribonucleic acid and genes changed in ways linked to biological pathways related to the brain.
Spiritual Experiences
Participants also completed the MEQ-30 Spiritual Experiences Questionnaire, which measures feelings like unity, transcendence, and consciousness shift during meditation. Scores increased from an average of 2.37 before the retreat to 3.02 afterwards.
Those reporting deeper spiritual experiences showed more pronounced biological changes, including increased coordination between different brain regions, suggesting that deeper subjective experiences might be linked to measurable changes in brain functions.
These results help explain how non-pharmacological methods like meditation can support general health practices. By enhancing neuroplasticity and influencing immune system activity, emotional regulation, stress resistance, and psychological health can be improved. The increase in natural pain-relieving chemicals also suggests potential applications in managing chronic pain.
Further Research
While the study focused on healthy individuals, the researchers point out the need for further research to determine how these findings can be applied to patients. Future studies will explore whether programs similar to this can benefit those suffering from chronic pain, mood disorders, or immune-related conditions.
The research team also plans to study how different elements of the retreat, including meditation, conceptual reframing, and placebo therapy, individually and collectively contribute. Other key questions include the duration of these biological changes and whether repeated practice can enhance or maintain them.
