I believe that many people have this feeling, when they are young, they often stay up late, and they are still alive the next day.
Once you are over the age of 30, as long as you go to bed a little later, you will feel unable to lift your energy the next day, and you will not be able to make up for sleep.
It's as if at some point in time, people suddenly age...... Actually, it's not your delusion.
In 2019, the team of Tony Wyss-Coray, a neuroscientist at Stanford University in the United States, published a study in Nature Medicine.
Research has shown that people do not age at a uniform rate.
And, there are three age groups that age the fastest, what is going on?
The essence of aging is actually a problem with the replacement of cells, and the structure of the human body is very complex, consisting of a large number of organs and tissues.
These all need the support of cells, and the older a species is, the more cells will age, and the body organs will also decline.
In middle and old age, it is always inevitable that the hair will turn gray, the face will have spots, and the skin will be wrinkled.
These are all signs of aging, however, we cannot see the changes in our organs.
A few years ago, Stanford University in the United States began research in this field.
To figure out the recessive changes in aging, the researchers surveyed 4,263 volunteers aged 18-95 years.
A total of 2,935 plasma protein trajectories of volunteers were analyzed by blood drawing.
This is an extremely large amount of work that neurologist Tony Wyss-Coray simply cannot do.
So Stanford University set up a group to specialize in experimental statistics and analysis.
With the active help of the students, the experiment process was much faster.
Eventually, the effort paid off, and after careful comparison, Tony Wyss-Coray discovered an astonishing scientific fact.
The plasma protein in the human body will fluctuate significantly at the age of 34, 60, and 78.
These changes are well consistent with the statistics of changes in some medical diseases.
In his view, human aging is not a slow process, but is divided into three stages.
Once you are 34, 60, or 78 years old, you will have a cliff-like aging.
People who are in these three stages will experience some subtle changes in their physical condition.
And these changes and characteristics make people feel like they have aged a lot overnight.
The first is thirty-four years old, an age group that can be said to be a middle-aged man in China.
The ancients said that standing at thirty is actually the most stressful life at this age.
After all, there are old and young, although people in this age group often have stable income jobs, but all kinds of trivial things in life can still torture people to exhaustion.
According to the statistics released by Sina Finance, the number of divorces in China in 2020 will be 3.733 million, ranking first in the world.
On the family side, it is also a piece of chicken feathers, so many people are old at this age.
For example, a woman who has just passed the age of 30 will have a lower metabolism than before, which can be seen from the face.
One of the more obvious features is that subtle nasolabial folds and wrinkles begin to appear, but they are not very noticeable.
And those who don't pay attention to maintenance may develop wrinkles before the age of 30.
After the age of 30, wrinkles increase significantly, and the texture becomes more and more pronounced.
This is actually caused by fluctuations in the composition of plasma proteins, which causes the loss of collagen in the face and the loss of elasticity of the skin.
There is no need to panic at this point, as there are some means to fix it.
Generally speaking, it is recommended to go to a large institution and find a qualified doctor to solve it.
If you don't have time to go, another way is to do health exercises to stretch your skin.
It has been proven that a daily skincare routine can also improve the appearance of the face, especially with a focus on hydration and protein.
The most important thing is to mediate emotions, go to bed early and get up early, and have a regular work and rest time.
Maintain a good and optimistic mood, which is also very helpful in the fight against aging.
The age of 60 is the second stage of rapid aging.
In the past, the World Health Organization set 60 years old as a watershed.
People over the age of 60 are defined as older people, and those between the ages of 60 and 74 are defined as young and elderly.
Nowadays, the times are progressing, and medical technology has been greatly improved.
In the past, those incurable diseases of old age can be effectively treated, once again extending the average life expectancy of human beings.
Looking at ancient times, people were rare in their seventies, and at that time, 70 years old was considered a long-lived old man, and forty or fifty years old could be called an old man.
Nowadays, 70-year-old people are all over the streets, and there should be no sense of antiquity.
After this age, the body is prone to some problems, but these are normal.
In our country, many elderly people have high blood pressure.
There are many reasons for its formation, which will not be listed here, and you need to pay attention to your diet and life.
Maintain a healthy diet Xi reduce your intake of greasy foods and salt.
If possible, you can be physically active, with at least 150 minutes of moderate-intensity aerobic activity per week.
If you have the Xi of smoking and drinking, then it is best to quit, no matter how good your body is, you can't withstand the harm of these two things.
Many elderly people are old and don't like to exercise much, which leads to weight gain and body gain.
Try to control your weight, as obesity can easily affect your blood pressure.
Some countries prefer to drink coffee, but for the elderly, the drink is also harmful.
Excessive caffeine intake may lead to a short-term increase in blood pressure, so drink coffee in moderation.
Eat less foods with high salt content, needless to say, the elderly basically know this.
The elderly have weakened body organ function and are more susceptible to external environmental factors.
In the past, when I was young, I didn't care how to eat Hesse, but once I passed that age, all kinds of foodborne diseases would come to my door.
Especially at the age of 78, which is the third stage mentioned in the Stanford University paper, the characteristics of aging will be more pronounced.
Often at this age, people are already retired and their children have successful careers, and they don't have to think about the gains and losses and difficulties in life.
At this time, I began to enjoy life, except for eating and sleeping every day, occasionally going out to exercise, and playing chess in the park.
However, it has also been noted that there are many elderly care facilities in the world that specialize in housing elderly people who have no one to take care of them.
In nursing homes, there is nothing wrong with the basic life of the elderly, but psychological problems are easy to be overlooked.
The long-lived elderly are easy to think crankily, not to mention that their children are not around, and their hearts are very empty and lonely.
In this regard, the advice of experts is to go outdoors to do more exercise, exercise at the same time, but also avoid cranky thoughts.
According to statistics, more than 5% of the elderly aged 65~69 in China will use smartphones to access the Internet.
In fact, it is a good thing for the elderly to go online, they can video chat with their family members, shorten the distance between relatives, and reduce anxiety in life.
At the same time, you can also learn about news events, watch movies and e-books on your mobile phone, and improve your knowledge.
At this stage, there is no need to think about how to resist aging, this is the law of nature, and no one can resist it.
Many people are curious that the essence of aging is a change in cell replacement, so is there a way to reverse this process.
To put it bluntly, reversing this process is equivalent to rejuvenation, which is something that only happens in science fiction movies.
But surprisingly, Tony Wyss-Coray, a neuroscientist at Stanford University in the United States, did research in this area as early as 2014.
The research team connected the blood systems of older mice and young mice, and then quietly observed their physical changes.
After a large number of comparative experiments, it was found that young blood can indeed improve the brain function of older mice.
It's just that it's not clear which component of the blood changes the brains of rats.
Later, the composition of plasma proteins in the human body was studied and many similarities were found.
It is worth mentioning that there are also gender differences in cliff-like aging.
For example, women enter the aging process more slowly than men.
We all know that in many countries, women have a higher life expectancy than men, which is very consistent with the results of the experiment.
Although women age faster than men in terms of protein, their faces are prone to wrinkles.
However, the aging rate of organs and brain is slower, and the life cycle of hematopoietic stem cells is longer than that of men.
If the future really masters the secret, then the life span of human beings will be greatly extended, and even rejuvenated.
