Want a simple medication-free way to reduce your potential for heartburn? Breathe more deeply. That’s according to Dr. Sophie Balzora, a gastroenterologist from NYU Medical Center. She says 30 minutes of deep breathing exercises every day can relieve acid reflux symptoms because it strengthens the muscles in your lower esophagus. So inhale through your nose, drawing air deep into your lungs, then exhale through your mouth. A good time to practice is when you’re commuting to and from work.
