One way to relieve muscle tension is to do progressive muscle relaxation, also known as Jacobson's relaxation technique. Progressive muscle relaxation (PMR) is a form of therapy that involves tightening and relaxing your muscle groups, one at a time, in a specific pattern.
Your body needs relaxation to reduce stress and calm the fight-or-flight response. It helps to plan for about 20 minutes of relaxation every day when you can take time for yourself. Sit or lie comfortably, limiting distractions like phones. Put on some soft music or simply sit in silence. Then incorporate the progressive relaxation technique below.
