Scientists say just 7 days of meditation can rewire your brain

An intensive weeklong meditation retreat at the University of California San Diego yielded significant changes in participants' brains and bodies, according to a recent study. The findings, published in Communications Biology, suggest that combining multiple mind and body practices may have far-reaching biological effects beyond relaxation.

Researchers observed alterations in brain activity, blood chemistry, immune signaling, metabolism, and pain control systems. They also noted signs of increased neuroplasticity, the brain's ability to adapt and form new connections. These results offer insights into how mental practices and conscious experiences can influence physical biology.

The study, supported by the InnerScience Research Fund, was part of a multi-million-dollar initiative. It is the first to comprehensively measure the biological impacts of several mind and body practices delivered together during a short, intensive program.

Senior study author Hemal H. Patel, Ph.D., explained that the research goes beyond stress relief, focusing on fundamental changes in how the brain interacts with reality. The program included daily lectures, approximately 33 hours of guided meditation, and group healing practices. Participants reported stronger mystical experiences, which were linked to increased communication between brain regions.
