What Are the Benefits of Breathing Oxygen?
The composition of Earth’s atmosphere consists of roughly 78 percent nitrogen, 20 percent oxygen and 2 percent of other gaseous elements, including water vapor, argon and carbon dioxide. Without oxygen, life on Earth would be drastically different. An essential element of life, oxygen acts as an electron acceptor during oxidative reactions in and outside the body, providing many benefits in terms of cellular respiration, health and muscular pain.
