Why are blue veins blue?

In daily life, when summer comes, everyone wears short sleeves. At this time, you will always see some people's arms covered with blue veins. At this time, it seems like it is about to jump out, and as we all know, the tendons of some animals are a little white, and you can see the difference on the arms. Many people want to know why they are different. So, why are blue veins blue?

This is because there are metabolic products and proteins in the venous blood, so it is blue.

Distribution of blue veins

A. “Blue veins” on the hands: The blue veins on the hands are closely related to the internal organs.

1. Blue veins on the back of hands: This indicates that there is stagnation in the waist and back, which can easily lead to lumbar muscle strain, fatigue, and common back pain. The more raised they are, the more back pain they suffer. The worse the waist is, the more blue veins they will have on the back of their hands.

2. Blue veins on fingers: The knuckles represent the transverse colon of the human body. In children, this indicates gastrointestinal stagnation and indigestion. In adults, it also reflects vascular microcirculation disorders in the head, insufficient blood supply to the cerebral vessels, and discomfort in the head. In severe cases, it may cause dizziness, headache, and even stroke. If the blue veins are at the base of the finger joints, it means there is a problem with the brain. If the blue veins on the transverse lines of the metacarpophalangeal joint of the middle finger are raised, twisted, and purple-black, it indicates cerebral arteriosclerosis. For children, it does not indicate a problem with the brain, but it indicates gastrointestinal stagnation and indigestion. If an adult has "blue veins" on the transverse lines of his index finger, it indicates that he is prone to left-side periarthritis of the shoulder. The presence of "blue veins" on the transverse lines of the little finger indicates that you are prone to right-sided periarthritis of the shoulder. If the transverse lines of the thumb metacarpophalangeal joint have raised and twisted "blue veins", it indicates coronary artery sclerosis of the heart. If they are purple or black, it means coronary heart disease is occurring. Stroke is related to the large intestine. Blue veins on the ring finger indicate stagnation in children and endocrine disorders in adults.

3. Blue veins on the palm: Blue veins on the thenar eminence below the thumb often affect low back pain and rheumatic joint pain in the lower limbs. If there are "blue veins" on the transverse wrist lines, it means that there are problems with the urinary and reproductive system, which often affects gynecological diseases such as irregular menstruation, heavy dampness, and leucorrhea. Nei Guan (the area three fingers away from the wrist crease) is where the pericardium meridian passes, so it has a great influence on a person's consciousness. If there are "blue veins" in Nei Guan, it often indicates heart disease, such as myocardial strain, irritability, heart tightness, palpitations, insomnia, and nightmares. The distribution of blue veins on Nei Guan is also very important. The closer the Nei Guan "blue veins" are to the Nei Guan acupoint, the earlier heart symptoms will occur. The more protruding, twisted, and purple-black the Nei Guan blue veins are, the more severe the symptoms of heart disease will be, and it may even indicate that a serious heart disease is about to occur. If there are "blue veins" on the inside of the lifeline, it is often seen in liver and gallbladder function metabolism problems, which can easily cause bitter taste, dry mouth, irritability, chest tightness, liver disease, etc. There are "blue veins" at the beginning of the lifeline at the base of the thumb, and women often experience breast pain before and after menstruation. The "blue veins" on the palms, even so shallow that they can be seen between the knuckles, indicate that there is stool stagnation in the intestines. Such people often suffer from habitual constipation or varicose veins, hemorrhoids, etc. Purple "blue veins" can be seen all over the palms, indicating gastrointestinal stagnation, high blood lipids, high blood viscosity, high blood pressure, high blood acidity, low oxygen content, and blood coagulation, which can easily lead to dizziness, headaches, fatigue, and physical weakness.

B. "Blue veins" on the head:

1. When there are bulging "blue veins" on the temples, it often indicates dizziness and headache. The pain is on the side where the bulge occurs. When the "blue veins" on the temples are bulging and twisted, it indicates cerebral arteriosclerosis. If they are purple or black, it is easy to have a stroke.

2. "Blue veins" on the forehead indicate long-term mental and physical strain, indicating work pressure or emotional stress;

3. The blue veins on the bridge of the nose are mostly children. Generally speaking, the nose is the digestive system, which means gastrointestinal stagnation, stomach pain, bloating, indigestion, and constipation. It is more serious when it is purple.

4. Eye bags with "blue veins". As the saying goes, spleen deficiency leads to large eye bags, kidney deficiency leads to dark eye bags, and "blue veins" under the eyes often indicate gynecological diseases, irregular menstruation, and leucorrhea;

5. "Blue veins" at the corners of the mouth or cheeks often indicate gynecological diseases, heavy vaginal discharge, fatigue, weakness in the waist and knees, and rheumatism in the lower limbs.

C. "Blue veins" on the chest: breast pain during menstruation, depression, and pay more attention to breast hyperplasia.

D. "Blue veins" in the abdomen: If the blue veins pass through the belly, it indicates serious stagnation. Adults with liver cirrhosis and ascites, and late-stage tumor cancer are common "blue veins" in the abdomen, which are often difficult to treat diseases.

As for why the blue veins are blue, it has a lot to do with one's physical constitution. Because there are some differences between us humans and ordinary animals, but after the introduction above, everyone knows why. My colleague also introduced to everyone what the distribution of blue veins symbolizes. You can take a closer look if you need.
