Ms. Li, a secondary school teacher, recently saw an online remark about blood vessels on the back of her hand and was skeptical. She decided to take the opportunity of the medical examination to ask the doctor for verification.
At the physical examination center, Ms. Li successfully completed various examinations. When the doctor measured her blood pressure, she boldly asked, "Doctor, I heard that the blood vessels on the back of my hand can tell the length of life, is it true?
The doctor smiled and patiently explained, "Ms. Li, what you heard is too one-sided. The state of the blood vessels on the back of the hand can indeed reflect some health information, but it cannot directly judge the length of life. In fact, there are many factors that affect lifespan, such as genetics, lifestyle, environment, etc., and the blood vessels on the back of the hand are only one of the small indicators. "
Ms. Li asked, "So, what should a healthy blood vessel look like on the back of the hand?"
The doctor said: "Generally speaking, a healthy blood vessel on the back of the hand should have the following characteristics: uniform blood vessel color, light cyan or light purple color, moderate diameter of blood vessels, not too small or thick, natural blood vessel direction, not many bifurcations, no obvious tortuosity or twisting, good elasticity of blood vessels, can quickly return to their original state after light press.
If the blood vessels in the back of your hands roughly match these characteristics, it means that your blood circulation is good and your blood vessels are functioning normally. "
Ms. Li breathed a sigh of relief, but was a little worried: "If the blood vessels on the back of the hand are not healthy, does it mean that there is a problem with the body?"
"Less healthy blood vessels on the back of the hand, such as dark, finely curled, stiff and protruding, may indeed indicate certain health risks, such as arteriosclerosis, high blood pressure, diabetes, etc. However, this is only a preliminary clue, and it needs to be combined with other signs and examination results.
Some people don't need to worry too much because the blood vessels on the back of their hands seem to be unhealthy, but their body indicators are normal. Conversely, some people may have a recessive disease that appears to have healthy blood vessels on the back of their hands. Therefore, the conclusion cannot be made based on the blood vessels on the back of the hand alone. "
Ms. Li nodded, convinced of the doctor's explanation. She said that she would pay more attention to the changes in the blood vessels on the back of the hand, and also pay attention to daily health management, regular physical examinations, early detection and early treatment.
Ms. Lee's story reflects the doubts and concerns that many people have about the blood vessels in the back of their hands. In the era of the flood of information on the Internet, the saying that "the blood vessels on the back of the hand look at the lifespan" is widely circulated, but in fact, there is not much scientific basis.
It is true that the state of the blood vessels on the back of the hand does reflect some health information. Healthy blood vessels on the back of the hand, uniform color, moderate diameter, natural orientation, and elasticity, these characteristics indicate smooth blood circulation and normal blood vessel function.
On the contrary, if the blood vessels in the back of the hand are dark, small, twisted, and stiff, it may indicate certain health problems, such as arteriosclerosis, high blood pressure, diabetes, etc.
Arteriosclerosis will thicken, harden and lose the elasticity of blood vessel walls, hypertension will cause continuous compression of blood vessels, resulting in thickening and twisting of the diameter of the tubes, and diabetes will cause microangiopathy and small curvature of blood vessels.
However, the blood vessels on the back of the hand are only a small part of the body's vascular network, and while its status can provide some clues, it is not indicative of the health of the blood vessels throughout the body.
Some diseases may not be visible on the dorsal blood vessels of the hand in the early stages, while some abnormal manifestations of the dorsal blood vessels may not be related to the disease, but only individual differences. Therefore, we cannot make judgments based on the blood vessels on the back of the hand alone, let alone simply infer the length of life.
In fact, the factors that affect longevity are complex, including internal genes and external living environment, uncontrollable age, gender, and lifestyle that can be changed.
A person's life expectancy is the result of a combination of factors, and the blood vessels in the back of the hand are only a small indicator of it, far less important than a healthy lifestyle.
It's like the doctor said, instead of paying too much attention to the blood vessels on the back of the hand, it is better to focus on daily health management.
Quit smoking and limit alcohol, eat a balanced diet, exercise moderately, and have an optimistic attitude, these seemingly simple details of life are the key to maintaining health and prolonging life.
At the same time, we should also develop a good habit of regular physical examination, detect and treat diseases in time, and do not wait for the blood vessels on the back of the hand to send out a warning signal before regretting it.
When dealing with network information, we must learn to distinguish rationally and not be easily superstitious. The doctor's explanation tells us that although the blood vessels on the back of the hand can reflect some health conditions, they cannot simply judge the length of life.
For ordinary people, instead of obsessing over the blood vessels on the back of the hand, it is better to start from daily life and cultivate a healthy lifestyle. Let us work together to treat life with a positive attitude, take care of health with scientific methods, and believe that on the road of health and longevity, we will eventually walk calmly and elegantly.
