The most well-known relaxation technique is Progressive Muscle Relaxation. It is based on the findings of the American scientist E. Jacobson that stressful situations are usually accompanied by an increase in muscle tension, while at rest, the muscles are relaxed. Based on this, he developed a method of relaxation, known as Jacobson Progressive Muscle Relaxation. It is a process in which a person learns how to relax different muscle groups in their body. Through continuous cycles of tension and relaxation of these muscles, the person observes exactly how they feel both during the tension and then during the relaxation. In this way they learn a better and earlier perception of tension in their body and learn how to release the accumulated tension and be able to relax.
Progressive Muscle Relaxation is one of the most popular methods of relaxation, because it is easy to learn and has proven to be very effective in treating anxiety and phobias, psychosomatic problems, as well as pain.
