A body scan is similar to progressive muscle relaxation except instead of tensing and relaxing muscles you simply focus on the sensations in each part of your body.
Practicing body scan meditation
Lie on your back, legs uncrossed, arms relaxed at your sides, eyes open or closed. Focus on your breathing, allowing your stomach to rise as you inhale and fall as you exhale. Breathe deeply for about two minutes, until you start to feel comfortable and relaxed.
Turn your focus to the toes of your right foot. Notice any sensations you feel while continuing to also focus on your breathing. Imagine each deep breath flowing to your toes. Remain focused on this area for one to two minutes.
Move your focus to the sole of your right foot. Tune in to any sensations you feel in that part of your body and imagine each breath flowing from the sole of your foot. After one or two minutes, move your focus to your right ankle and repeat. Move to your calf, knee, thigh, hip, and then repeat the sequence for your left leg. From there, move up the torso, through the lower back and abdomen, the upper back and chest, and the shoulders. Pay close attention to any area of the body that causes you pain or discomfort.
Move your focus to the fingers on your right hand and then move up to the wrist, forearm, elbow, upper arm, and shoulder. Repeat for your left arm. Then move through the neck and throat, and finally all the regions of your face, the back of the head, and the top of the head. Pay close attention to your jaw, chin, lips, tongue, nose, cheeks, eyes, forehead, temples and scalp. When you reach the very top of your head, let your breath reach out beyond your body and imagine hovering above yourself.
After completing the body scan, relax for a while in silence and stillness, noting how your body feels. Then open your eyes slowly. Take a moment to stretch, if necessary.
