What can I use to reduce stress?

Meditation, yoga, deep breathing, and other practices that encourage mindful relaxation encourage the body to be less sensitive to stress. Plus these practices force more oxygen into your body, which will amp up your energy metabolism and streamline your systems. Deep breathing, using the muscles of your diaphragm (you should feel your belly expand and deflate with each inhale and exhale), can also help calm your mind and release tension in your abdominal muscles, easing indigestion. It will also further help flush toxins and inflammatory molecules from your body. Another way to calm the body's autonomic nervous system -- which regulates digestion, among other things -- is through progressive muscle relaxation, tightening and then relaxing small groups of muscles beginning in your toes and working your way up to your face.
