Mindfulness-Based Stress Reduction (MBSR) is a structured program designed to help individuals manage stress and improve their overall well-being. Developed by Jon Kabat-Zinn in the late 1970s, MBSR combines mindfulness meditation and yoga to promote awareness of the present moment. Participants learn to observe their thoughts and feelings without judgment, which can lead to reduced anxiety and improved emotional regulation. The program typically lasts eight weeks and includes weekly group sessions, guided meditations, and home practice. MBSR has been widely studied and shown to be effective in reducing symptoms of stress, chronic pain, and various mental health conditions.
