When you stand up after squatting, your eyes are often dark and your mind is dizzy.

Not sure. You don't know if it's every time or occasionally, but there are two types of anemia, and the first is anemia, which is mostly iron deficiency anemia, which is iron supplementation (which is the disease).

The second is transient, which is that the brain cells work too long and fatigue is also caused by drinking water and going out to blow the wind, but after a long time, it can still evolve into a disease.

But don't worry. Because I'm like that too!! Hehe, it would be nice to eat more red dates.

I also experience this situation very often, which is more normal!

1.There is also the possibility that you may have low blood pressure and it is recommended that you measure your blood pressure.

2.The other is that you have a temporary lack of blood in your brain due to squatting, and you recover after standing up.

Is it every time? It's okay if it's not that serious, and there are times when you squat for a long time.

This is a normal physiological phenomenon.

Don't worry. A lot of people have it.

You just try to avoid squatting for a long time.

The reason is mainly because:

The moment you stand.

Due to the factor of gravity.

Result in. The venous vessels of the lower extremities bulge.

Its HP capacity increased suddenly.

The amount of blood returning to the heart is reduced.

It's like your body suddenly losing a few hundred milliliters of blood, and all that blood goes to fill the blood vessels). Your brain will not have enough blood.

The body then recovers through its own regulatory mechanisms.

Dilatation of the veins results in a decrease in the amount of blood returning to the heart.

This leads to insufficient blood supply to the brain.

Think about it. When you raise your hands above the top, you can't see the veins.

And when you hang your hand, do you see a vein?

It depends on the location of the heart and blood vessels.

The heart is low when squatting.

A lot of blood vessels collapsed.

There are many blood vessels in people.

So the vein dilation after standing can cause you to lose hundreds of milliliters of blood instantly.

Many people have this experience: after squatting for a long time and then standing up suddenly, they will feel dizzy and dark. The main reason for this phenomenon is temporary anemia in the brain.

When a person is squatting, the waist and legs are twisted and turned, and the blood cannot flow up and down. If you stand up suddenly at this time, the blood will flow down quickly, resulting in local ischemia in the upper body, but the brain and eyes have particularly strict requirements for oxygen and royal bucket nutrients. If you are already weak, the situation is more serious.

However, don't panic when this happens, and you don't have to go to the hospital. If the blood supply to the head is insufficient, the heart will immediately work hard to pump blood up, and it will not take long for the body to return to normal. Of course, when you stand up, don't move too violently, as slowly as possible, so that the blood does not flow too violently, and the blood supply to the heart can keep up, and this phenomenon will not occur.

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

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.

Therefore---1, people with this phenomenon are usually not squatting for a long time, if they have to squat often due to work, they 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.

This is normal, and I do it a lot. In addition, you can measure your blood pressure, people with low blood pressure also love dizziness.

Iron deficiency anemia only.

Temporary lack of oxygen.

It's quite normal that most people are mildly hypoxic and fine.
