Mindfulness-based stress reduction, or MBSR, for anxiety is much more than just a long, official-sounding, somewhat intimidating name. MBSR is an accessible process that helps people of all ages, beliefs, and backgrounds turn stress and struggles like anxiety into positive change for their lives. Developed by Jon Kabat-Zinn in 1979, MBSR is a program that uses mindfulness to enhance wellbeing. In doing that, MBSR reduces stress and anxiety when they interfere in your life. Whether or not you participate in a formal program, you can use MBSR to rein in your anxiety and stress.
