In ordinary life, everyone should experience such a phenomenon, for example, at a certain time, the time of squatting on their own, more than ten minutes, or more, then when you suddenly stand up, you will find yourself with Venus in your eyes, feel that the whole person is dizzy, and the "little star" is directly in front of you, what is going on?
In fact, in order to figure out the reasons behind this phenomenon, we must also have a detailed understanding of some relevant physiological knowledge.
Normal physiological phenomena
This situation many people will appear, so some people may know that this is a normal physiological phenomenon, because when we squat, the upper body will press the blood vessels of our lower body, squatting for a long time will also cause the upper body and the brain to be in a state of hypoxia, suddenly standing up will make the heart strong contraction, then the human body's blood pressure will increase suddenly, and under the action of high pressure, the brain will appear brief dizziness, and even the eyes will be black, but basically it will return to normal. Such a situation is basically normal and there is no need to worry too much.
There is also that if the blood pressure can not be restored in a short period of time, the blood pressure is all concentrated in the lower body, the blood pressure in the brain part is reduced, and there will also be dizziness and black eyes, both of which are physiological reasons, as long as we move slowly when we squat up, we can solve this situation well, and it will not harm the health of the body.
Suggestive of blood pressure viscosity
The phenomenon of black eyes and dizziness when squatting down is not necessarily the cause of anemia or low blood sugar, but is likely to be related to our blood. If our blood is viscous, then when the blood pressure rises, it cannot pass through the blood vessels very smoothly, it is easy to block in the capillaries of the brain, and when it is mild, it may be dizzy and black, and when it is serious, there may be a danger of blood clots.
Therefore, if there is such a situation for a long time, we should also pay attention to it, usually adjust our living habits, eating habits, drink more water and exercise more, which will help improve the flow rate of blood and ensure the blood supply of various organs.
How to adjust the black halo syndrome usually
If you really find such a situation, you should not be careless, first of all, you must look at your body, is not in a state of anemia, if there is no such state, then it is not caused by pathological anemia. On the contrary, if you rule out these situations, after standing up and finding that there is black halo, it is a problem of your own position, so at this time, you should slowly stand up, let the blood distribution of the body, there is a short self-regulation process, do not stand up at once, and squat down at once, so it is easy to cause black halo.
If you often feel dizzy, black in front of your eyes, and risk the phenomenon of "Venus", you must pay great attention to it, go to the hospital to do a comprehensive examination when necessary, and be able to understand the health of the body in time. In addition, in life should also develop good habits, in addition to paying attention to diet and strengthening physical exercise, but also to ensure adequate sleep, and adjust their mentality, do not scare themselves.
