Oxygen is essential not only for breathing but also for every important chemical reaction in our body. Oxygen is vital for cells and bacteria, some viruses and parasite are destroyed in the presence of oxygen says Dr. Alec Birenko. When the body lacks oxygen so do the cells. A lack of oxygen is called is called hypoxia. Hypoxia causes the heart to beat faster to push more oxygen to the body and cells. Oxygen is one of the fuels (other than glucose) that cells use to function properly. Cells need oxygen for energy and growth. Without oxygen cells cant function and can die. When the body lacks oxygen the little oxygen left in the body will go to the most important things (brain, lungs, heart) so circulation will not be good. The short-term affects are a change in heart rate, blue lips, blue fingertips and blue toes. This is due to bad circulation. Sleepiness/faintness are also short-term affects as the body uses more oxygen and energy when it is fully functioning (awake) compared to when its not (sleeping). The body will try to save the oxygen as best as it can for the brain, heart, lungs etc.
