TWH – Meditation and mindfulness practices have been a mainstay of many Pagan practices. In some traditions, meditations and similar contemplative practices are central to spiritual development.
A new study reveals that mindfulness meditation significantly alters brain activity, even during rest. The Australian researchers in Australia used advanced brain-scanning technology to explore whether long-term meditators display distinct patterns in brain waves compared to non-meditators. The brainwave patterns could explain the cognitive and emotional benefits of mindfulness practice.

Mindfulness meditation, often touted for stress reduction and improved mental clarity, involves staying fully present in the moment without judgment.
Decades of research have suggested that mindfulness offers a wide range of physical, emotional, and cognitive benefits, making it a powerful practice for overall well-being. By fostering present-moment awareness without judgment, mindfulness helps reduce stress and anxiety, promoting a sense of calm and emotional balance. Studies show that regular mindfulness practice can enhance attention, memory, and cognitive flexibility, leading to better decision-making and improved focus. It has been linked to lower levels of cortisol, the stress hormone, which may contribute to improved cardiovascular health.
Emotionally, mindfulness increases self-awareness and empathy, helping individuals manage difficult emotions more effectively. Furthermore, it reduces worrying and rumination, which can lead to greater resilience and a more positive outlook on life. Physically, mindfulness can improve sleep quality and boost the immune system by reducing chronic stress. Whether practiced through meditation, mindful breathing, or body awareness exercises, mindfulness offers lasting benefits, enhancing both mental clarity and emotional well-being in daily life.
However physiological markers that can grade how mindfulness meditative practices are going have been difficult to come by. While previous research has linked mindfulness to better mental health and focus, this study sheds light on what’s happening in the brain.
The research published in the journal Mindfulness may offer a clue. The study focused on differences in theta, alpha, and gamma brain wave frequencies. These changes, seen in both the strength and distribution of brain activity, suggest that meditation reshapes neural processes over time.

“We know mindfulness benefits mental health, but the exact brain changes behind these improvements aren’t fully understood,” said Neil Bailey, a senior research fellow at Australian National University.
Bailey noted that while earlier studies examined brain activity during meditation or specific tasks, fewer explored how meditation impacts the brain at rest. His team aimed to clarify this by analyzing how brain waves behave when participants are simply relaxing.
The study involved 92 participants—48 experienced meditators and 44 non-meditators. Using electroencephalography (EEG), a technique that measures electrical brain activity, researchers captured brain waves while participants rested. To focus on lasting effects rather than temporary meditation states, participants avoided meditating during the scan.
After cleaning the data of noise, such as eye movements, researchers zeroed in on key brain wave types. They found that meditators had significantly higher levels of theta, alpha, and gamma brain waves, each linked to different mental functions:
- Theta waves: These increased most in the back of the brain and are associated with focus and memory.
- Alpha waves: Meditators showed a shift in alpha activity from the back to the front of the brain, possibly reflecting better control over distracting thoughts.
- Gamma waves: Often tied to higher-order thinking and sensory integration, gamma activity was especially strong in the frontal brain regions of meditators.
Interestingly, no differences were found in beta waves (linked to alertness) or in non-rhythmic brain activity, suggesting the changes were specific to theta, alpha, and gamma frequencies.
One caveat is that the study’s design doesn’t prove meditation causes these brain changes; it’s possible that people with naturally different brain activity are more drawn to mindfulness practices. However, previous research suggests that meditation likely plays a role.
The findings add to growing evidence that mindfulness meditation can reshape the brain, offering insights into how these changes might enhance mental health. “Our work could help improve treatments for mental illnesses,” Bailey said, noting that meditators also showed brain wave patterns that align with reduced rumination—a key factor in better emotional well-being.
While more research is needed, these results reinforce the idea that mindfulness is not just a practice for the mind but also a powerful tool for shaping the brain. If the brainwave differences are confirmed, they may open a toolbox to determine how students are developing and progressing via their meditations practices.
