Why do I get dizzy when I squat and then stand up?

Standing up suddenly will cause the brain to be instantly insufficient, and you will be a little dizzy, and you will not have this situation if you stand up slowly.

Because when you squat, the blood will go down, and when you stand up, the blood will not go up all of a sudden, and your eyes will turn white or black, and you will get used to it all of a sudden, just like if you keep your hands held high, when you take it down, you will be a little cold, and then it will be hot, because the blood will not be cold, because there is no blood, and it will be hot because the blood has just arrived, which is normal.

The view of traditional Chinese medicine is: "hair is more than blood". It means that the blood can be observed from the hair.

The hair is yellow and dull, which is the reason why the blood is insufficient and cannot be moistened, and dizziness when squatting and standing up is also a sign of mild anemia. If tinnitus occurs in a short period of time, it is related to liver fire (or phlegm fire); If it is prolonged, it is related to blood deficiency (or kidney deficiency), which needs to be diagnosed by a doctor. Occasional bleeding from the nose is related to liver fire and qi deficiency, and it also needs to be diagnosed by a doctor.

Although there are many problems, it is certain that the blood is relatively insufficient, and we should pay attention to nutrition on weekdays; Other problems should be clearly distinguished, and those who are real and those who are empty should make up for it, and they must see a doctor, and they are easy to solve.

When squatting, the lower limbs are flexed, and the blood vessels of the lower limbs are compressed so that the blood is not easy to flow to the lower limbs, and the lower limbs appear to be ischemia. When a person who has been squatting for a long time suddenly stands up, the blood vessels of the lower limbs are restored to unblocked, and at this time, it is like suddenly opening the floodgates, and the blood will rush to the lower limbs in large quantities, so that the head will not have enough blood, and the brain will not get enough oxygen and nutrition for a while. The conclusion is:

Most of this phenomenon is a normal phenomenon and is not caused by anemia. Reminder: 1. It is best not to squat for a long time for people with this phenomenon, if you have to squat often due to work, you can prepare a low stool in advance to reduce the degree of flexion of the lower limbs; 2. When standing up after squatting for a long time, it is advisable to stand up slowly to reduce the discomfort caused by this; Care should even be taken to clean up the work site to prevent injuries after a brief loss of consciousness and a fall to the ground.

3. It is advisable to participate in more physical exercise to enhance cardiovascular function. Why do people get dizzy when they stand up after squatting for a long time? If you squat on the ground for a little longer, and when you stand up suddenly, you often feel the world spinning and your eyes are full of stars.

This is caused by temporary anemia of the head. When a person is squatting, there are some special cases for the distribution of blood in the body. The first is that the two legs are pressed very tightly, the blood vessels are flattened, and the blood reaching the lower limbs is relatively small; Secondly, because the head is slightly tilted forward when squatting, the blood to the head is relatively more distributed.

When you stand up suddenly, the blood vessels in the lower limbs suddenly release the compression, so a significant part of the blood flows to the lower half of the body. In addition, blood also has a certain weight in the body, and when you stand up suddenly, the blood flow will also flow to the lower half of the body due to the attraction of gravity and inertia, and the blood distributed to the upper body will be reduced. In addition, when standing up, the head is also upright, and it is more difficult to spurt blood from the heart to the high head.

All of this results in a relative decrease in blood flow to the head. The human brain is the most in need of blood oxygen, and a temporary reduction in blood supply can make people feel dizzy due to temporary cerebral anemia. In addition, due to the decrease in blood in the head, the blood supply to the eyeballs is naturally less, so the phenomenon of dazzling and Venus will occur.

At the same time, anemia and hypoglycemia can aggravate this phenomenon.

Many people have had similar experiences, and it's okay, you have to get up slowly when you get up, don't stand up suddenly.

When a person is in a squatting position, the lower limbs are flexed, and the blood vessels of the lower limbs are compressed so that the blood is not easy to flow to the lower limbs, and the lower limbs appear to be ischemia.

When a person who has been squatting for a long time suddenly stands up, the blood vessels of the lower limbs are restored to be unblocked, and at this time, it is like suddenly opening the floodgates, and the blood will rush to the lower limbs in large quantities, so that the head will not have enough blood, and the brain will not get enough oxygen and nutrition for a while.

The conclusion is that this phenomenon is mostly a normal phenomenon and is not caused by anemia.
