Diaphragmatic breathing quiets and calms the entire nervous system, reduces stress and anxiety, and improves self-awareness.
Lie comfortably on your back with your knees bent and your feet flat on the floor. Place a palm on your abdomen and breathe comfortably for a few breaths. Notice how your breath feels, without any judgment.
As you do this, begin to make your breathing as relaxed as possible, smoothing it out by pausing briefly after each inbreath and outbreath.
Once this feels comfortable, notice how your body is moving. As you inhale, the abdomen expands and as your exhale, your abdomen contracts. As you notice this, try to bring to control to this natural movement for 6 to 12 breaths.
