Progressive Muscle Relaxation
In this relaxation technique, you focus on slowly tensing and then relaxing each muscle group.
This helps you focus on the difference between muscle tension and relaxation. You become more aware of physical sensations.
One method of progressive muscle relaxation is to start by tensing and relaxing the muscles in your toes and progressively working your way up to your neck and head. You can also start with your head and neck and work down to your toes. Tense your muscles for at least five seconds and then relax for 30 seconds, and repeat. Source: Mayoclinic.org
