![]() When the free radicals, the oxidation, form in the body, the number of inflammations increases. The reaction is the same as when metal rusts, or when the apple’s pulp becomes brown when exposed to light and oxygen. As oxygen is a very reactive gas, excess leads to an increased amount of free oxygen radicals, also known as oxidative stress. But when we breathe too much, as many of us do, we get too much oxygen in the body and too little carbon dioxide. If we stop breathing, we die because of oxygen deficiency. It needs the right amount, adapted to the needs there and then, as it differs greatly depending on whether you drive on the highway at 110 km/h or at 30 km/h in a residential area. Our car stops both if it gets too much or too little fuel. Just as little as a car work better because it gets more fuel, nor does our body work better because we take more breaths and inhale more oxygen. It’s all about the balance between oxygen and carbon dioxide Instead this over breathing, 2-3 times more than normal, gives an opposing effect, which imposes a heavy load on our body, much like eating 2-3 times more than normal. When we already have such high oxygen saturation, and furthermore only use a quarter of the oxygen we breathe in, there is no purpose of breathing the 10-15 liters per minute that many of us do. The oxygen saturation of hemoglobin is easily measured with a pulse oximeter attached to the finger or the ear. At a normal breathing volume at rest, hemoglobin is already saturated with almost as much oxygen as it can, 96-98 percent. The oxygen travels around the blood bound to hemoglobin. At the same time, the amount of carbon dioxide we exhale is about a hundred times higher than the amount we inhale. Therefore we exhale the remaining seventy-five percent. We already have a large surplus of oxygenĪt a breathing volume of six liters per minute, we only use about twenty-five percent of the oxygen we inhale. This over-breathing implies a low-grade form of hyperventilation, which leads to an imbalance between oxygen and carbon dioxide – we get too much oxygen in the body while at the same time removing too much carbon dioxide through exhalation. But many of us breathe a lot more, often 18-25 breaths per minute and up to one liter of air per breath, giving a breathing volume of up to 10-15 liters per minute. Normal breathing at rest is about 6-12 breaths per minute and about half a liter of air per breath, giving a total breathing volume of about 3-6 liters of air per minute. What is normal breathing volume and what is hyperventilation? However, nothing could be further from the truth. Generally, oxygen is considered to be the amazing life-giving substance, while carbon dioxide is just a toxic waste product that we want to get out of the body as soon as possible. This article, however, is about the levels of carbon dioxide in the body, but here too, carbon dioxide has a bad reputation. The increasing amount of carbon dioxide in the atmosphere means that more infrared heat from the sun is reflected back to earth and stays here, instead of returning into space. It is estimated that before 1750, when industrialization began, the levels of carbon dioxide were approx. ![]() ![]() In other words, a 33% increase in a relatively short period of time. 315 ppm (parts per million), 0,031%, to approx. Since the measurements started in 1958 at Mauna Loa Observatory in Hawaii, the levels of carbon dioxide have increased from approx. And the levels of carbon dioxide, also called greenhouse gas, in the atmosphere have indeed increased. Carbon dioxide emissions are painted as the major culprit behind global warming. Perhaps you’ve heard of carbon dioxide before, but probably not in any positive terms.
