The dangers of breathing pure oxygen

We live in this world and need to exchange materials every day. Although some of these materials cannot be seen or touched, we cannot live without them all the time, and that is oxygen. As we all know, normal air contains about 78% nitrogen, about 21% oxygen, and about 0.939% rare gases. That is to say, oxygen only accounts for a part of what we inhale. So do you know what harm will happen if people inhale pure oxygen?

What are the hazards of breathing pure oxygen?

Because cells will be killed under high oxygen conditions, breathing pure oxygen will cause organs to be oxidized. A cut apple will turn brown if left in the air for a long time, which means it has been oxidized. Carbon dioxide can stimulate the nerve center and make people breathe actively, but inhaling pure oxygen will paralyze the nerve center. This is called "oxygen poisoning". At the present stage of human evolution, the basic breathing volume is gas composed of about 70% nitrogen and other substances. If you inhale pure oxygen, it may cause an imbalance of acid and alkali in the body, which will lead to illness. Can't exhale pure oxygen.

Advantages and disadvantages of breathing pure oxygen:

Inhaling pure oxygen does more harm than good and is not beneficial to blood supply. No tissue in the human body can withstand excessive oxygen. This is because oxygen itself can react with unsaturated fatty acids without enzyme catalysis and can destroy the phospholipids that store these acids. Phospholipids are the main components of cell biological membranes, ultimately causing cell death. This process is called lipid peroxidation. In addition, oxygen damages cells by producing free radicals, which can induce cancer.

Experiments have shown that the way to destroy cell cultures is to place them in an environment with supersaturated oxygen. Pure oxygen can reduce the body's blood supply to its own organs and tissues, resulting in a decrease in blood vessel pressure due to the reduction in carbon dioxide. When carbon dioxide is added, blood vessels begin to dilate, which increases blood flow and allows more oxygen to reach key areas such as the brain and heart, causing disruptions to various body functions.

Oxygen inhalation, in which nitrogen acts as an inert diluent, regulates the solubility of oxygen in the blood and, together with carbon dioxide, controls the rate of all biochemical reactions in which oxygen participates.

2. What are the effects of inhaling pure oxygen:

1. Oxygen inhalation makes your body healthier: Oxygen inhalation can increase tissue activity, enhance system function, effectively improve sub-health conditions, and enhance physical fitness and disease resistance.

2. Oxygen inhalation can prolong life: As humans age, their bodies gradually age and degenerate. The blood and oxygen supply to various organs will be insufficient to varying degrees, and aging is closely related to lack of oxygen. Hypoxia accelerates aging, and oxygen intake and utilization are affected to a certain extent with aging. Hypoxemia is a major factor in the decline of intelligence, physical strength and resistance in the elderly. Health oxygen inhalation is one of the effective measures against aging.

3. Oxygen inhalation can beautify and nourish the skin: Oxygen inhalation can enhance cell activity, reduce skin sagging, increase its toughness and elasticity, maintain a healthy luster, and achieve the effect of maintaining youth. Oxygen inhalation can promote aerobic metabolism in the brain, refresh the mind, enhance memory, and improve learning and work efficiency: it has a positive effect on alleviating and improving the test anxiety symptoms of college entrance examination students such as excessive brain use and excessive psychological pressure caused by long-term intense review. It can effectively relieve adults' brain fatigue symptoms such as dizziness, headache, insomnia, memory loss, etc. caused by long-term mental work, stressful work, and excessive use of the brain, and improve work efficiency.

4. Oxygen inhalation during pregnancy can make the baby healthier and smarter: the fetus relies on the mother to supply sufficient oxygen through the umbilical cord. Fetal intrauterine hypoxia can cause intrauterine growth retardation, premature birth, fetal distress, deformity, mental retardation, etc. Oxygen inhalation can correct fetal intrauterine hypoxia, promote fetal development, improve placental function and protect the fetus. It can reduce the risk factor for high-risk pregnancies, reduce premature births, stillbirths, mental retardation or disability, and make the babies born healthier and smarter. Oxygen inhalation plays an auxiliary therapeutic role in cardiovascular and cerebrovascular diseases, respiratory diseases, and common geriatric diseases (such as tremor, diabetes, and Alzheimer's disease). It can relieve symptoms and stabilize the condition.
