What is nitric oxide? Nitric oxide is a gas that is inhaled. It works by relaxing smooth muscle to widen (dilate) blood vessels, especially in the lungs. Nitric oxide is used together with a breathing machine (ventilator) to treat respiratory failure in premature babies. Your baby will receive this medication in a neonatal intensive care unit (NICU) or similar hospital setting.
But new research suggests that exercise may also help increase the production of nitric oxide, a substance that does a variety of important jobs in the body, perhaps none more valuable than to help prevent heart disease. Nitric oxide does a variety of jobs, explains Dr. Jason Allen of Duke University. It tends to be antiatherogenic, which means that it helps prevent your arteries from becoming clogged. That is, it's a function of what you eat, how you exercise, and the stresses you are under.
