Mindfulness involves paying attention to the present moment nonjudgmentally. Practicing mindfulness through meditation can lead to changes in brain structure and function. Studies have shown increases in gray matter in areas related to learning, memory, and emotion regulation after only 6 weeks of mindfulness training for 20-30 minutes per day. Mindfulness reduces the stress hormone cortisol and increases growth of the hippocampus. It helps strengthen the prefrontal cortex and create a state of "flow," improving focus, resilience, and well-being.
