These factors are inevitable, but it is possible to slow down the aging process. Expert of the National Cancer Center in Spain Manuel Serrano is one of the authors of the study "Signs of Aging". Experts conducted this study to show the main processes that occur in the body over time.. In total, scientists have identified nine factors indicating that a person is aging..

According to the findings of Serrano, these are unavoidable factors..

“They may be more or less noticeable depending on a person’s lifestyle and genetics. But they always happen, ”the expert said in an interview..

So, what accompanies aging?.

DNA damage accumulates This genetic code is always transferred from one cell to another. With aging, the number of errors that may appear in the process increases.. These errors gradually accumulate in the cells..

This is called genetic instability.. This phenomenon can threaten the work of stem cells.. By the way, it is from these cells that others form with different functions.. With the accumulation of errors, these cells can become cancerous.

Chromosomes wear out.

DNA strands at their endings have telomeres, these are peculiar protective "caps". As they age, they wear out and chromosomes become more vulnerable.. This means that they are incorrectly reproduced, which causes problems..

Destruction of telomeres leads to diseases such as fibrosis and aplastic anemia - a serious immunological disease..

But there is good news: scientists have already learned how to increase the level of telomerase - a substance that lengthens telomeres. Experiments on mice have shown that increasing the length of telomeres can prolong the life of rodents..

Cell mobility worsens.

Many genes in a particular cell determine what a cell can do, for example, behave like a cell of a body or brain.. Lifestyle and time have a direct impact on the implementation of these "instructions". Cells can change their "behavior".

Cell renewal is declining.

To prevent the accumulation of "waste" in our cells, consisting of non-working parts, the body regularly updates the cell set. However, with age, this ability is lost, and the cells begin to accumulate in themselves toxic or useless components, which, in consequence, contributes to the development of Alzheimer's disease, Parkinson’s disease or cataracts.

Decreased metabolism With age, cells lose their ability to process fats and sugars.. This is usually the cause of age-related diabetes.. Unfortunately, the body of the elderly is not able to process all that they eat..

The work of the mitochondria stops Mitochondria - this is the energy "engine" of the cell, over time they begin to lose their effectiveness.

According to scientists, improved mitochondrial functions can increase the life span of mammals..

Cells become “zombies”. A damaged cell stops its work in order not to reproduce other “spoiled” cells.. She no longer multiplies, but not in a hurry to die. These "zombies" can affect adjacent normal cells and harm the entire body.. Over the years, these cells become more and more. During experiments on mice, the removal of zombie cells helped slow the aging process..

Stem cells lose energy Loss of reducing potential is perhaps the most obvious sign of aging.. Stem stops recovering over time. However, studies have shown that stem cell rejuvenation can slow down signs of aging..

Communication between cells is disrupted. This happens gradually and eventually leads to inflammatory processes that further complicate intercellular communication..

As a result, cells lose sensitivity to the presence of pathogenic substances and malignant cells..

Serrano argues that the study and understanding of intracellular aging processes will contribute to the invention of new methods of slowing the wear of human organs and tissues.. Although this process is inevitable, but to slow it down is real, all you need to do is lead a healthy lifestyle..

"Nowadays, the life of older people has become much richer and healthier than in past decades. The best thing we can do is enjoy life even when we are getting old, ”says the scientist.
