Human aging and hypoxia are two sides of the same body, and they also interact with each other.

First, without oxygen, any organ in the body cannot function, and organ dysfunction will naturally occur. And aging refers to the gradual decline of the function of the whole-body organs, which also includes the decline of cardiopulmonary function. When the cardiopulmonary function declines, the body can obtain less oxygen, and the oxygen delivered to the various organs of the body also decreases. As people age, the production of red blood cells also declines, so the elderly is more likely to suffer from anemia. In addition, aging also affects erythropoietin (synthesized by the kidneys and liver), the production of red blood cells decreases, and the amount of blood produced by the bone marrow and other hematopoietic organs also naturally declines, which is one of the reasons for anemia in the elderly.

Red blood cells are insufficient for various reasons, and the lack of oxygen in the body will increase.

The relationship between aging and hypoxia can also be observed and explained from the "number of breaths".

The number of breaths of human beings, and that of children is the highest, is due to the fast metabolism. The metabolism of the elderly is slowed down, and the number of breaths increases, which means that the efficiency of the elderly to absorb oxygen is reduced, so the number of breaths should be increased to make up.

After aging, there will be sclerosis of the peripheral blood vessels, resulting in poor circulation. Therefore, not only the organs will have problems, but there will also be hypoxia in the surrounding area, so wrinkles and bone spurs will also appear.

If the elderly people can keep oxygen therapy each day, the aging can be delayed.
