Why do humans age? Is human aging irreversible?

Why do humans age?

Attrition theory,Humans, like other chemicals that exist all over the world, whether living or not, are constantly being recreational and destroyed over time. The reason why people get old is also related to the psychological pressure that we can bear during long hours of work, study and training, and our hearts. Theory of genetic inheritance,This view holds that human beings grow old according to the genetic program, and the length of an individual's life depends on their genetic program.

Theory of Genetic Variation in Life Processes,This view is that the aging of the human body is due to some institutional changes in the body during the life process, resulting in the reduction of the body's immunity, the decline of endocrine disorders, the accumulation of cellular mutations and their metabolic sediment, and the final result is aging.

Is human aging irreversible?

Growing old is an irresistible law of nature. With the passage of time, the characteristics of the body's organs slowly decline, and the immunity slowly decreases. There are also two kinds of aging, one is physical aging, and the other is spiritual aging.

Physiological aging is a matter of molecular biology expertise, a necessity for the continuous development of life, and such passage is inevitable.

With the change of people's age at any time, people slowly relax, lung function slowly decreases, gastrointestinal function weakens, and teeth wither or even fall off. Some of the most important functions of the visual organs, such as the visual effect, auditory system, olfactory nerve, etc., will also gradually decline. Human aging generally begins at the age of 35, and the human body slowly declines and its reflexes decrease.

It's an irreversible process, so we don't need to feel guilty about it, and although aging is inevitable, we can slow down aging, mainly in terms of diet and sleep.

People at different ages have different sounds. However, when a man's voice becomes more high-pitched as he gets older, it may be a sign of aging. As a result of the age of 70, men's cartilage tissue becomes softer and the larynx becomes more and more unstable.

The woman's voice also becomes deeper because the female body's estrogen secretion decreases, and the larynx becomes more and more distended.

This is because people are inseparable from water and food in the process of growth; I think yes, it is a natural process for people to grow old from birth to old age, and it is impossible for anyone to be immortal and not die, so aging is irreversible.

This is because all organs of the human body are constantly reducing their efficiency in the process of operation; It's really irreversible, and everyone has to go through it.

The aging of people is due to both physiological and pathological causes. Human aging is irreversible and can only be delayed through diet and fitness.

3. Disease is also another cause of aging. The last point is that in recent years, more and more people have found that they have residual diseases, and these diseases are also an important reason for the dysfunction of the human body and the function of various organs, and the appearance of damage to the human body.

The aging process continues from the fertilized egg to death, and it is only at a certain stage that the characteristics of aging become more apparent.

When there are problems and wear and tear on the cells, they continue to accumulate, and they will age, such as work pressure, endocrine disorders, and human maintenance is also one thing.

Human beings are multicellular organisms, and human aging is also determined by cells, cells will age, and will slowly lose proteins, which will make human ** yellowish and lose luster.

This is because people have a certain metabolism, cells and the like, have their own life, which is determined by people's genes, as well as the birth, aging, sickness and death of cells.

1. Environmental factors, human health and longevity are related to the natural environment of the area where they live, such as topography, climate, hydrology, soil and biology. The world's four most famous regions have been internationally recognized: the western Himalayas in China, Hunza in Kashmir in Pakistan, Vilibamba in Ecuador in South America, and Georgia in the Caucasus.

The environment has a certain impact on human lifespan, but there is no single factor that favors longevity. Scientific research suggests that fresh air, water, the right ambient temperature, light eating habits and biological adaptability are all factors for longevity.

2. Genetic and racial factors, different individuals in the same era and the same social background have great differences in life expectancy, and this difference is determined by the inherent genetic factors of the individual. Generally speaking, families with long-lived parents also have children who live longer, which shows that genetics plays an important role in human lifespan.

The relationship between race and longevity is formed over a long period of biological evolution. The population of the same race is basically in a cluster state, and its average life expectancy is related to the geographical environment, social environment, economic development level and traditional living habits. There is a high incidence of diseases in different ethnic groups, which have been proven to be genetically caused, and also affect life expectancy.

Ways to slow down aging

1. Reasonable nutrition, aging may be related to genetics, free radicals, and lipofuscin, and reasonable nutrition can inhibit the role of the above-mentioned factors that cause aging, and have the function of delaying aging. Generally speaking, the diet should be regular and quantitative, according to the physiological characteristics and nutritional needs of middle-aged and elderly people, consume sufficient nutrients and make nutrition balanced and reasonable.

2. To strengthen health education, children should start with self-care and receive health care knowledge education throughout their lives. Health care institutions should disseminate health care knowledge to all people, especially the middle-aged and elderly, so that people can understand the significance of health care, disease prevention, and anti-aging, and know specific measures to delay aging.
