Squat down for a while and get dizzy

This is inertia, Sang, when you get up, the blood in your head is still in the soles of your feet, even if it can't flow to the brain, causing brain ischemia.

When a person squats, due to the compression of the legs, the blood of the whole body goes down, and when he stands suddenly, the blood does not have time to flow back to the brain, resulting in temporary ischemia of the brain, and the symptom is black eyes and dizziness, and after a while, he will be fine. However, if you have cardiovascular and cerebrovascular diseases, it is highly recommended not to do so for the sake of your life.

In fact, everyone will feel dizzy when they suddenly get up after squatting for a while, which is not a sign of anemia, but just a temporary lack of blood supply to the brain.

That's because the blood can't be transported to the head for a while, and the temporary lack of oxygen in the head will cause dizziness and dark eyes.

It is a phenomenon caused by insufficient blood supply to the brain, and it will get better after a while.

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 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.

Due to squatting for a long time or lying down for a long time, the blood will be in a balanced state because of squatting or lying down for a period of time, and the blood circulation caused by standing up suddenly will not be smooth enough will cause insufficient blood supply to the brain, and most people will have a similar situation, such as no anemia for the time being. Just take proper rest.

Due to the lack of smooth blood circulation due to squatting for a long time, standing up suddenly will cause dizziness and ,.. due to temporary blood supply or ischemiaIf it is severe, or if it occurs more frequently, it may be considered to be anemia.

Dizzy? You're anemic! It may still be the more serious kind. Kindness... Eat more peanuts and dates, it has a great blood tonic effect!

Because when you crouch, there is very little blood flowing to your brain, so you may feel dizzy.

I am often like that, according to me, I know that it is anemia, you need to eat more red dates, or make up some calcium, it's okay, squat down and stand up again, most people will faint, if you are often dizzy, it really means that you are anemic

When I get up, my blood pressure rises rapidly.

Why do you get dizzy when you stand up after going to the squatting "toilet", do you know what the reason is?

Strengthen exercise, proper nutrition, your blood pressure is too low, blood pressure can not be supplied when squatting up, so that you have insufficient blood supply to the brain so dizzy, it is recommended to go to a regular hospital to check whether you are anemic, I wish you health.

I've had that experience too. According to what you said, there may be problems with your blood circulatory system, under normal circumstances, your body's blood circulation can still maintain normal flow, when you suddenly change a certain state, the speed of blood circulation can not keep up, so the brain has a short-term lack of oxygen supply, and the brain is the "headquarters" of the nerve center system, which directly affects the nerve center, and finally manifests as a state of dizziness, and in severe cases, you will even feel fatigue, unable to stand and want to fall. Therefore, when you want to squat, you must pay attention to the surrounding environment, especially whether your feet are flat, in case you faint and cause more serious situations.

It's called blackopia. It's similar to the following state.

When a person is squatting, the lower limbs are flexed. At this time, the blood vessels of the lower limbs are compressed, and the blood is not easy to flow to the lower limbs, and the lower limbs will be in a slight ischemic state, and they will feel numb after a long time. When you suddenly stand up after squatting for a long time, the blood vessels in the lower limbs suddenly return to unblocked, as if the floodgates have been opened suddenly, and a large amount of blood will rush to the lower limbs.

The amount of blood produced by a person in a certain period of time is certain, and a large amount of blood rushes to the lower limbs, so that the blood in the head is not enough, and the brain does not get enough oxygen and nutrients for a while, so most people will have the phenomenon of black vision.
