Introduction: Since ancient times, health and longevity have been topics that people have always paid attention to. Everyone wants to stay healthy and live a long life, but birth, old age, illness and death are the laws of nature and cannot be avoided by anyone.
We often hear elderly people say: It’s hard to accept old age. The bones in your body are indeed not as good as before. Although everyone doesn’t want to face aging, it is a normal physiological phenomenon. Everyone has been in the process of aging since they were born. A step towards aging.
As age increases, various functions will gradually decline. At this time, the body will send out some aging signals. Especially after the age of 70, you will obviously feel that all aspects are incomparable with before. So what exactly is it? What factors lead to "cliff-like" aging after the age of 70?
New Cambridge study: After the age of 70, does the body show a cliff-like aging?
In order to uncover the answer to this mystery, scientists from the Wellcome Sanger Institute and the Wellcome-MRC Cambridge Stem Cell Institute in the UK recently completed a study.
Researchers sequenced the hematopoietic cells of 10 subjects aged from 0 to 81 years old. The sequencing data showed that hematopoietic stem cells/pluripotent progenitor cells accumulated an average of 17 mutations per year after birth, and the average telomere length was lost every year. 30 base pairs of to .
By sequencing the whole genomes of 3579 blood stem cells, we identified all somatic mutations contained in each cell. It was found that after the age of 70, the population structure and differentiation pattern of human hematopoietic stem cells undergo tremendous changes.
The blood cells produced by adults under the age of 165 come from 20,000 to 200,000 stem cells . In contrast, the source of blood cells in people over 70 years old has dropped significantly, and they can even differentiate into only 10 to 20 stem cells.
These "highly active" stem cells often have mutations, which can lead to an irreversible reduction in the diversity of blood cell populations in the elderly, disrupt the production of normal functional mature blood cells, and ultimately induce a variety of aging-related diseases.
It can be seen that the age of 70 is an obvious watershed in human aging. But before that, the body was actually aging quietly.
If your body has these four symptoms, it means that you have entered the aging process.
1. Osteoporosis
After the human body ages, the digestive function of the gastrointestinal tract has also declined, which will affect the body's absorption and utilization of nutrients such as calcium. Without a large amount of calcium in the bones, osteoporosis is prone to occur.
2. Old skin and hair
Sagging skin, more and more wrinkles, and more hair loss. The essence of skin aging is related to the aging of human cells, and cell aging is the most essential problem in human aging and should cause people's most attention. Pay attention, because cells are the smallest units that make up the human body. When they age, the human body ages naturally, and the skin is naturally the most external manifestation.
3. Frequent insomnia
If you have symptoms such as frequent insomnia, excessive dreams, or a particularly light sleep, you are likely to enter the process of aging. If not, you must maintain good sleep quality to alleviate aging. If you have long-term insomnia, Please be careful, you are on the downhill road of getting older. Live rationally for a better tomorrow.
4. Gastrointestinal signals
As we age, we will obviously feel that the gastric motility decreases after eating, and the intestinal peristalsis ability weakens. Sometimes we will also feel indigestion, bloating and constipation after eating. These are all related to the decline of gastrointestinal muscles. .
To delay aging, do these 4 things
1. Moderate exercise
Exercise can increase the skin’s aerobic respiration time, increase blood circulation in the body, and can improve skin condition in the fastest time. It has an important impact on skin texture. Moderate amount Exercise can keep the body's functions running continuously. A large amount of perspiration can promote the body's metabolism, improve the body's immunity, and delay aging.
2. Soak your feet in hot water
The feet are farthest from the heart. Compared with other parts, it is less easy to get sufficient oxygen and blood. If you can soak your feet in hot water before going to bed, it will not only promote blood circulation, but also It can speed up metabolism and make people younger.
3. Drink more water
Water is the source of life. All physiological activities of the human body are inseparable from water. Lack of water will lead to an increase in wrinkles and lines, and cause more dry areas and dullness.
If the body is dehydrated, the body will definitely get worse and worse. Therefore, you must drink more water to fight aging.
Four, maintain mental health
A person’s mental state affects the functional activities of various organs. Negative emotions such as loss, anxiety, worry, depression, anger, hostility and frustration often conflict with the psychology and can often lead to dysfunction of some organs of the human body. If it is not corrected in time, over time, severe cases can often induce psychosomatic diseases of the cardiovascular system, respiratory system, etc.
Conclusion:
Although aging is unavoidable, we can delay the arrival of aging through reasonable and effective methods. It is not too late to start health care at any age. Let us act quickly.
