Mindfulness-Based Stress Reduction (MBSR) is a systematic and rigorous 8-week course developed more than 40 years ago by Jon Kabat-Zinn, PhD to help individuals and patients learn to take better care of themselves by understanding the mind-body connection and mobilizing their own inner resources for coping, healing, and thriving. Nearly three decades of scientific research suggest that training in mindfulness (paying attention, on purpose, in the present moment, nonjudgmentally) can positively affect one's ability to reduce medical symptoms and psychological distress while learning to live more fully. Public interest and clinical research on mindfulness has exploded in the past ten years within the areas of healthcare, business, education, and sports performance.
