Why do people get dizzy after squatting for a long time, and why do they get dizzy after squatting f

People squat for a long time, in fact, do not feel dizzy, but when they stand suddenly, they will be dizzy and even dark in front of their eyes due to the temporary lack of oxygen caused by the inability of blood in the legs to return immediately (because of the obstruction of the venous valves in the blood vessels) to the brain. If you stand slowly, this is less likely to happen, especially for older people

The posture causes the pressure in the abdominal cavity to be greater than the atmospheric pressure, the depth of breathing becomes shallow, and the brain is deprived of oxygen.

Anemia, which leads to a lack of blood supply to the brain.

It is the moment you get dizzy when you stand up, because the blood flows backwards, causing the brain to lack oxygen.

Sudden ischemia of the brain is also called cerebral anemia.

When people squat, the blood is not evenly distributed'

Stand up so that the brain is not supplied with snow'

The blood is not circulating, Bei is really stupid.

I agree with everyone.

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 nutrients, and they must not be slackened. 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 standing up, don't move too hard, try 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 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 dizziness, heartbeat, and black vision. After the body adapts and adjusts, this phenomenon disappears quickly in most people. Therefore, most of this phenomenon is a normal physiological phenomenon, and it is not a disease such as anemia.

This may be caused by cerebral hypoxia, generally speaking, there will be no big problem, or it may be caused by insufficient blood supply to the brain, as long as you breathe more fresh air every morning, eat more vegetables and drink more water, there will be a significant improvement.

This is a temporary cerebral insufficiency. When you squat down, the lower limbs will be flexed, and the blood vessels in the lower limbs will be pressed so that the blood will not be easy to flow to the lower limbs, and the lower limbs will appear to be ischemia. Also, when you stand up after squatting for a long time, the blood vessels in the lower limbs will be restored to the smooth flow, and the blood will rush to the lower limbs in large quantities, so that the blood in the head will not be enough.

Many people think that it is anemia, but this phenomenon is not necessarily anemia, it may be a physiological phenomenon. People with this phenomenon usually do not squat for a long time, and when standing up after a long squat, they should stand up slowly to reduce the discomfort caused by this; It is advisable to participate in more physical exercise to enhance cardiovascular function. Exercise more, and all problems will patronize you less!

Usually sometimes it may be brain fatigue, our brain can't always be tired, we must always rest, Qian Shumei, remember to rest!!

People with anemia will experience symptoms such as pale mucous membranes, dizziness, dizziness, tinnitus, fatigue, palpitation, shortness of breath, poor appetite or indigestion. You can compare it to see if you have any of these symptoms.

I've been squatting for a long time. Your blood returns more slowly in the lower limbs, which will make your brain supply less, so if you feel dizzy, just get up a little slower, not so violently. Especially for the elderly!

You can give you a few light coughs before you get up. Because the blood is all in one place when you crouch! When you cough lightly, the blood disperses! That's probably how it is explained! I saw it on a TV show! You can give it a try!

Blood compression when squatting.

It is not easy to flow downward.

When you stand up, a large amount of blood will rush to the lower limbs, so that the head will not have enough blood, and the brain will not get enough oxygen and nutrients for a while, and dizziness will occur.

This phenomenon is mostly normal.
