If we squat for a long time, the blood supply to the brain will be insufficient, so we will feel dizzy when we stand up, and if we have low blood pressure or malnutrition, this situation will be more violent.
-
That's because the blood supply to the brain is insufficient, and when we suddenly stand up after squatting for a long time, our blood flow to a high place can't keep up with the speed at which we stand up, which causes dizziness.
-
When squatting, the position of the blood supply to the heart will change, the blood balance of the human body will change, and standing up suddenly will cause ischemia in the brain, so it will be dizzy.
-
This may be caused by your low blood pressure, or it may be caused by greater strength, at this time the cerebral hemorrhage, but when you need to get up more slowly, there will be no more dizziness.
-
It is caused by anemia, probably because your body is not very good, so you will have dizziness, at this time you should take care of your body more, and usually eat some blood-replenishing food.

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.
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.
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.
Normal people are basically like this. Because of the fierce stand up. Caused by insufficient blood supply to the brain
Every day we are using our bodies to complete all kinds of work, but we do not serve our bodies well, and we do not know enough about our bodies, and there are many friends who don't know what is going on when they stand up and have black eyes after squatting for a long time? Then let Lemon tell you! >>>More
Many people will have insufficient blood supply to the brain, so there is no need to be nervous. Be careful not to squat or sit for too long, when you wake up, the blood will flow to the lower body, and the brain will be ischemic and cause dizziness.
How old are you? It may be lumbar intervertebral disc lesions, ** a lot, which needs to be specifically analyzed.
Because of squatting for a long time, the blood flow speed of the lower limbs is significantly slower than that of the upper body, and it will instantly speed up blood circulation all of a sudden, resulting in a feeling of dizziness, generally a few seconds, if the dizziness lasts for a long time and there is obvious discomfort, it may be anemia, it is recommended to drink some brown sugar water, eat some jujubes, eat more tomatoes, and eat at least one eggplant a day.
