What is the relationship between oxygen and aging - do you know the "hypoxic aging theory"?
What is the relationship between oxygen and human aging?
What is the hypoxic aging theory?
Why accelerated aging after chronic hypoxia?
What is the vicious cycle of hypoxia, aging and re-hypoxia?
In the long process of human aging, there are many substances that affect human aging. There is one substance that plays a very important role throughout.
It's oxygen.
Oxygen accounts for the highest proportion of human needs, up to 61%, followed by carbon at 20%, hydrogen at 12%, and the rest such as nitrogen, calcium, chlorine, phosphorus, sulfur, fluorine, sodium, magnesium and iron
The lungs of the fetus in the mother are not breathing, and the fetus is constantly drawing oxygen and various nutrients from the mother through the blood in the placenta. When a crying newborn cries for the first time, lung tissue opens up for the first time, as if to announce to the world, "I'm here." And the world's first gift to him was oxygen.
Hypoxic senescence theory
Chronic hypoxia and aging are mutually causal, chronic hypoxia will accelerate our aging, while aging itself will also bring chronic hypoxia of the body, although its arrival is fast and slow, but ultimately everyone has to face.
In 1969, foreign scholars measured that the elderly increased by one year, the arterial blood oxygen partial pressure decreased by an average of 3 mm Hg, that is, with the increase of age, the oxygen partial pressure gradually decreased, the appearance of hypoxia. This is also known as the "hypoxic aging theory."
The vicious circle of hypoxia, aging and re-hypoxia
Chronic hypoxia will promote the aging of various organs, accelerate the process of aging, and lead to a variety of chronic diseases.
Aging is not a phenomenon that suddenly occurs after middle age, but is the result of the continuous changes that occur in the various organs and systems of the body as we age.
The first is the aging of the cardiovascular system
It begins the earliest, from the age of 25, the function of the heart is significantly reduced, blood pressure is also increased, 25 years old young people's heart can be 4 liters per minute to the cell oxygen, to 70 years old can be halved.
For example, the heart is like the "generator" of other systems of the body, the blood vessels are like "wires", the aging of the "generator" and "wires", the lack of power, will inevitably affect the entire working system, resulting in the aging of other systems of the body.
Second is the aging of the respiratory system
One obvious sign is an increase in residual lung volume. What is lung residual capacity? The amount of gas that remains in the lungs after deep inspiration. The alveolar residual capacity of the elderly increases, and the residual alveolar capacity of a healthy person aged 60 is almost double that of a healthy person aged 30.
Finally, the aging of the central system
Memory loss, mental retardation, and even dementia.
As a result of the aging of these human systems, the amount of oxygen ingested by the elderly is directly reduced, the ability to transport oxygen is reduced, and the efficiency of using oxygen is reduced, so that the entire body tissues are in varying degrees of chronic hypoxia.
Therefore, chronic hypoxia may be ignored, but the ensuing aging, followed by a series of chronic diseases, can not be ignored.
Although advanced medicine has been able to quickly, centrally, and effectively correct hypoxia problems, we still hope to avoid the aging organs and diseases caused by chronic hypoxia.
