Meditation not only helps reduce stress by lowering your heart rate and blood pressure, it can also help you focus, learn, and remember. Try it by sitting in a quiet, comfortable place, closing your eyes and relaxing your muscles. Breathe through your nose and, as you exhale, silently say a single-syllable word, such as om. Do this for 10 to 20 minutes. When you're done, sit quietly and keep your eyes closed for a few minutes. Open your eyes and sit quietly for another few minutes before getting up.
