The ancient Greek philosopher Heraclitus said, "One cannot step into the same river twice" because the river keeps flowing.

Similarly, the next second you will be different, because your cells are constantly aging and updating.

The life span of our red blood cells is four months, the life span of intestinal epithelial cells is less than one week, and the life span of skin epidermal cells is about one week to one month. If the tongue is burned, it takes about two weeks for the taste bud cells to renew.

Each of us wants to slow down aging, but how to achieve it?

First, let's understand the two steps of cell renewal:

First, remove aging cells in time.

Second, replenish enough new cells, the source of which is stem cells.

Today we will discuss the first step of aging, that is, eliminating aging cells-

After aging, cells must be able to die smoothly and be removed in time. Otherwise, the risk of cardiovascular disease, cancer and other senile diseases will be greatly increased.

The following papers published in the journal Nature show that actively removing aging cells helps to stay young.

Now, let me introduce how cells die.

First, the way cells die, that is, "apoptosis", is like the death of leaves. Under the control of genes, cells will be broken into pieces in an orderly manner and swallowed by immune cells.

Second, death is unnatural, that is, cell death caused by the attack of bacteria, viruses and mycoplasma is called "cell necrosis". This kind of cell death is rapid and violent, unlike the orderly death of apoptosis, which will cause inflammatory reaction in the body.

Thirdly, "scorching death", also known as "inflammatory necrosis of cells", is between apoptosis and necrosis, and participates in the pathogenesis of atherosclerosis, nervous system diseases and other diseases.

Fragments and inflammatory factors released by aging cells will enter the blood if they cannot be removed by immune cells in time, which will increase the burden on the blood circulation system and immune system and cause general discomfort, as if the body always has a burden.

-Blood purification: removing aging cell debris-

Blood purification is helpful to remove harmful components such as aging cell debris, endotoxin and inflammatory factors in blood.

Just like purifying a polluted lake, the purified fish will gradually increase and regain their vitality.

So is blood purification. After purification, the immune system will reduce the burden and the body's resistance will be enhanced.

In addition, timely removal of aging cells is conducive to the differentiation of stem cells into new functional cells and keeping the body young.

Stem cells: the source of life and youth—

Stem cells can replenish new cells for the body and delay the aging of the body through a large number of self-replication and directional differentiation. Stem cells are the source of youth in our lives.
