The list of health benefits attributed to meditation keeps on growing. Last year, I detailed how mindfulness meditation can help people manage pain, stress, and overeating and even led to the growth of brain regions associated with improved memory and emotional regulation. Now, a new clinical trial has found that transcendental meditation -- which involves focusing on a sound or mantra -- can lower the risk of heart attacks, strokes, and deaths in African-American heart disease patients who practiced the technique for 20 minutes a day.
