Research is mounting that a natural, potent source of stress relief is right in front of your nose. New science is showing that slowing down and deepening your breathing can have profound effects on well-being. “Many researchers can’t imagine how something so simple could actually have effects on physiology,” says Dr. Andrew Weil, a physician and founder of the Arizona Center for Integrative Medicine at the University of Arizona. Breathing exercises–a staple of mindfulness and yoga practices–have been shown to help control blood pressure, improve heart rate, make arteries more flexible and activate the parasympathetic nervous system, which tamps down the body’s fight-or-flight response to stress. Weil and other experts now believe deep breathing has a place in a clinical setting.
“It’s enough to warrant applications in several areas of medicine,” says Dr. Luciano Bernardi, an internal-medicine professor whose research shows that slow-breathing exercises improve exercise capacity in patients with chronic heart failure. “We’ve shown that this simple thing has a fantastic series of effects.”
