Relaxation techniques: Breath focus
Deep breathing is the foundation of breath focus, which is quite simple to do.
Find a comfortable, quiet place to sit or lie down. Start by noting the difference between breathing normally and breathing deeply. First take a normal breath. Now try a deep, slow breath. The air coming in through your nose should move downward into your lower belly. Let your abdomen expand fully. Now breathe out through your mouth (or your nose, if that feels more natural). Alternate normal and deep breaths several times. Pay attention to how you feel when you inhale and exhale normally and when you breathe deeply. Shallow breathing often feels tense and constricted, while deep breathing produces relaxation.
Now practice deep breathing for several minutes. Put one hand on your abdomen, just below your belly button. Feel your hand rise about an inch each time you inhale and fall about an inch each time you exhale. Your chest will rise slightly, too, in concert with your abdomen. Remember to relax your belly so that each inhalation expands it fully. As you exhale slowly, let yourself sigh out loud.
