From the moment a baby croaks, life begins a long journey of life.
With the advancement of science and technology and the improvement of medical conditions, life expectancy has greatly increased.
However, there are also many people who have not experienced "old age", have been plagued by diseases, and even lost their lives early.
The health of blood vessels is closely related to the overall health of a person.
Especially at the moment when the "three highs" are prevalent, many middle-aged people in their 40s and 50s have shown signs of "senescence before they get old", and the aging degree of their blood vessels is close to that of a normal 70- to 80-year-old.
There is a way to help our blood vessels to rejuvenate or delay aging without taking medicine and injections, and it is "exercise"!
Why can exercise delay vascular aging?
Today, a cardiologist will reveal to you how a beneficial substance produced by exercise makes our body younger.
Its efficacy starts with the Nobel Prize
In 1998, two pharmacologists were awarded the Nobel Prize for discovering the unique role of nitric oxide in the cardiovascular system.
Their experimental object is nitroglycerin, a commonly used drug for the treatment of myocardial infarction and angina pectoris. After research, it was found that it is not nitroglycerin itself that produces the drug effect, but the "nitric oxide" generated by metabolism after it enters the human body. The substance acts to dilate blood vessels, promote blood flow, and relieve chest pain.
With the deepening of the research, the researchers also found that our body can also synthesize nitric oxide, and it can be generated throughout the body and in the endothelial cells of the arteries.
Nitric oxide can reduce the mean arterial blood pressure of the whole body, control the resting tension of various vascular beds in the whole body, and increase the local blood flow. It is the main regulator of blood pressure.
In addition, the researchers also confirmed that nitric oxide has a certain role in preventing thrombosis - which is of great significance for those patients at risk of cerebral infarction and myocardial infarction.
Exercise can help the body achieve double "age reduction"
As mentioned earlier, nitric oxide mainly exists in the vascular endothelial tissue.
The healthier the vascular endothelial tissue, the more nitric oxide is produced.
What is the principle of this?
Exercise accelerates blood flow, which not only stimulates the activity of cells throughout the body, but also activates the "endothelial ribozymes" that produce nitric oxide.
And people who regularly participate in exercise have more active "endothelial ribozymes".
At the same time, people who love to exercise can eliminate the oxides in the body faster, and can produce some antioxidants to help the body reduce the production of oxides, which is equivalent to protecting the nitric oxide that has been generated.
Therefore, people who love sports can not only produce more nitric oxide, but also reduce the damage of nitric oxide to a certain extent.
Then there will be more nitric oxide left behind successfully - these nitric oxide will help the vascular endothelial tissue to maintain a healthier state, and finally form a virtuous circle.
Eat more of these to keep the good stuff in your body
However, nitric oxide in the human body is easily broken down, especially in the presence of peroxides.
Therefore, in order to keep the human body with more stable nitric oxide, the antioxidants in the body should be increased and peroxides should be removed in time - vitamin C and vitamin E just have this effect.
Fresh fruits and vegetables, fish, red wine and fruit juices contain a lot of antioxidants, including vitamin C and vitamin E, of course, so eat more.
Foods such as frying and grilling are the stronghold of peroxides, so eat them sparingly.
Of course, the introduction of nitric oxide in this article is only a shallow taste. In fact, the related research is very complicated and profound.
For example, it controls inflammation, maintains the functioning of the gastrointestinal system, helps to breathe more smoothly, and helps the male reproductive system.
If everyone thinks that theories are too boring, then look at the people around you who eat moderately, love sports, and don’t smoke or drink. Do you envy the beauty of their health?
So do it!
