The Relationship Between Hypoxia and Aging
Hypoxia? Aging?
In the long process of human aging, there are many substances that affect human aging. Among them, there is a substance that plays a very important role from beginning to end.
It is oxygen.
Oxygen is an indispensable element in life activities and plays a vital role in maintaining the normal physiological functions of organisms. In the human body, oxygen enters the lungs through breathing, and is then transported to various tissues and organs throughout the body, participating in the metabolic process of cells and providing energy for the body.
Oxygen accounts for the highest proportion of substances needed by humans, up to 61%, followed by carbon, accounting for 20%, hydrogen accounts for 12%, and the rest such as nitrogen, calcium, chlorine, phosphorus, sulfur, fluorine, sodium, magnesium and iron account for a very small proportion.
The fetus' lungs in the mother's body do not breathe. The fetus continuously absorbs oxygen and various nutrients from the mother through the blood in the placenta. A newborn baby who fell to the ground, when he cried for the first time, the lung tissue opened for the first time, as if announcing to the world, "I am here." And the first gift the world welcomes him is oxygen.
Oxygen enters the lungs of the newborn and opens the alveoli. From this moment until the end of his life, he will never be able to live without oxygen. Oxygen will accompany him throughout his life as he grows and ages.
Oxygen can make young life grow. At the same time, due to the unchanged demand for oxygen in the body, the relative lack of oxygen due to changes in the environment or human metabolism and the reduction of the ability to utilize oxygen will cause the body to age.
Do you understand?
Hypoxia aging theory
Chronic hypoxia and aging are mutually causal. Chronic hypoxia will accelerate our aging. At the same time, aging itself will also bring chronic hypoxia to the body. Although it comes faster or slower, everyone will eventually face it.
In 1969, foreign scholars measured that for every year of age, the average arterial oxygen partial pressure decreases by 3 mmHg, that is, with the increase of age, the oxygen partial pressure gradually decreases, and hypoxia occurs. - This is also called the "hypoxia aging theory".
Now, let's take a look at the changes in blood oxygen partial pressure with age.
Hypoxia-aging-hypoxia again
Forming a vicious cycle
Chronic hypoxia will promote the aging of various organs, accelerate the aging process, and lead to a variety of chronic diseases.
Aging is not a sudden phenomenon after people pass middle age, but the result of continuous changes in various organs and systems of the body as they age.
- First is the aging of the cardiovascular system
- The second is the aging of the respiratory system
- Finally, the aging of the central nervous system
The results of the aging of these human systems directly cause the elderly to have a reduced amount of oxygen intake, a reduced ability to transport oxygen, and a reduced efficiency in using oxygen, which puts the entire body tissue in a state of chronic hypoxia to varying degrees.
Therefore, chronic hypoxia may be negligible, but the aging that follows and the series of chronic diseases that follow cannot be ignored.
Then, ensuring adequate oxygen supply to the body is of great significance for maintaining vitality and promoting overall health. Oxygen is an indispensable element for driving cell metabolism and energy generation. Supplementing the body's lack of oxygen as soon as possible can enhance physiological functions, improve the body's defenses, effectively avoid the hidden dangers of physical decline and slow thinking that may be caused by hypoxia, and enjoy a more energetic life.
