Sitting on a stool, why do you get dizzy after a long time?

A phenomenon that causes a decrease in blood flow to the brain due to the dilatation of blood vessels.

This phenomenon may be caused by exposure to the scorching sun for too long, too long in a hot bath, or insufficient blood supply such as nervousness and anger. Check to see if there is anemia.

If you get dizzy when you sit for a long time, it's normal. If you are dizzy when you are sitting, only once or twice once in a while, it may be that you have not rested well due to recent stress, and if it is often like this, then you must go to the hospital for a check-up.

It is estimated that you will be unwell after a long time of concentration, so it is recommended to check your blood sugar.

If this is often the case, it means that there is some kind of problem in your body, but people generally think that it is anemia, low blood sugar, etc., but it may also be caused by blood pressure, cardiovascular and cerebrovascular, nervous and other diseases.

If it happens occasionally, it is normal, everyone's physique is different, the length of time is different from people's cardiopulmonary function, if it is strong, it may be okay to sit for a few hours, and if it is not strong, maybe squatting down and picking up something will see Venus. Be careful not to stand up in a hurry, but to stand slowly, so as not to let the blood vessels not withstand the pressure caused by the impact of blood, which will be fatal!

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. On the other hand, 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. Most of this phenomenon is a physiological phenomenon and is not caused by anemia.

People with this phenomenon should not squat for a long time, if they have to squat often because of work, they can prepare a low stool or a small chair that can be folded in advance, and sitting and working can reduce the degree of flexion of the lower limbs; When standing up after squatting for a long time, it is advisable to stand up slowly to reduce the discomfort caused by this; People with this phenomenon should usually participate in more physical exercise to enhance cardiovascular function. To put it simply: after squatting down and then standing up, due to the gravitational effect of the blood, the blood cannot rise in time, which makes the brain lack oxygen, causing dizziness.

I feel that this answer is more comprehensive, turn around, and I don't know if it will be useful to you!

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

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.

It could be anemia, my mom was anemic, that's it.

It means that your blood pressure is low, you are anemic, when you stand up, don't be so fast, just stand up slowly, and usually pay more attention to blood replenishment!

Then you may have symptoms of anemia, go to the hospital for a check-up!!
