There are certain activities that require extreme physical exertion and controlled breathing. Swimming, running, singing, and yoga are some of these activities. They require great lung capacity. There are several ways to increase the efficiency of our lungs. Breathing is the only autonomic function over which we also have conscious control. To understand the right way to breathe, watch a baby resting on his/her back. The baby's belly swells like a balloon when it inhales, and deflates when it exhales.
