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.

Dizziness, cerebral insufficiency, malnutrition, blood pressure.
