After strenuous exercise, many people will experience dizziness and lack of oxygen to the brain. We know that this is due to insufficient blood supply to the brain. As the commander of the human body, the brain is in charge of the operation of various organs of the body and the domination of nutrients. Only when the brain ensures sufficient blood and nutrient supply can the normal operation of the body be maintained.

Once the brain lacks blood supply, it will disrupt the balance of the body and cause a series of health problems, so when these three symptoms appear in the head, be careful not to have insufficient blood supply to the brain.

One, transient blindness

Vision is a more sensitive core part, and it is relatively close to the brain, so when the blood supply to the brain is insufficient, the eyes, as a neighbor of the brain, will perceive it faster, especially the lack of blood supply is often accompanied by insufficient oxygen supply.

Therefore, transient blindness is easy to occur, that is, the eyes are darkened and things cannot be seen clearly, but soon the blood supply can meet the demand and can be restored.

Second, headache and dizziness

Occasional headaches and dizziness may be caused by poor sleep quality, but if frequent headaches and dizziness occur, sometimes accompanied by numbness or weakness in the limbs, be careful, this may be caused by cerebral ischemia. Manifestations of neurological disturbances.

Three, facial numbness

The face has a more important trigeminal nerve, and the trigeminal nerve is connected to the brain, and the perception will be more sensitive. Once the brain is severely ischemic, it may cause obvious numbness in the face.

Therefore, when transient blindness, frequent headaches, dizziness and facial numbness occur, it means that the brain has been frequently ischemic.

Do three precautions and four precepts to prevent insufficient blood supply to the brain

1. Anti-water shortage

Once the body is dehydrated, it will easily lead to an increase in blood viscosity and poor circulation, so it will affect the blood supply to the brain, resulting in the appearance or aggravation of insufficient blood supply to the brain.

Second, anti-three high

The three highs may indirectly affect the operation of blood in the blood vessels, leading to blockages, which may easily induce insufficient blood supply to the brain.

Third, prevent carelessness

It is necessary to grasp the physical condition, so don’t be careless about it. You should have regular physical examinations, early detection and early control, in order to ensure the healthy state of the brain and avoid the situation of insufficient blood supply to the brain.

Fourth, quit heavy taste

Heavy-taste foods tend to increase the risk of three highs and cardiovascular and cerebrovascular diseases, so the habit of light diet must be maintained to help the brain maintain a healthy state.

Five, quit anger

Sudden and strong emotional fluctuations may cause a sudden increase in blood pressure, and as a result, it is easy to induce insufficient blood supply in the blood vessels, and may even lead to cardiovascular and cerebrovascular diseases.

Six, quit being lazy

If you lack outdoor exercise on weekdays, it may lead to obesity and chronic diseases, and induce cardiovascular and cerebrovascular diseases. Therefore, even if you cannot do a lot of outdoor exercise, you should avoid sitting and lying down for a long time, and increase your activity.

Seven, quit staying up late

If you stay up late for a long time, you will inevitably lose sleep time. Too little sleep time may increase blood pressure and increase the pressure of blood vessels, which may easily lead to insufficient blood supply to the brain, causing a series of discomforts.

To sum up, in order to prevent insufficient blood supply to the brain, we must pay attention to preventing water shortage, preventing three highs, and preventing carelessness, and quitting heavy-taste eating habits, quitting anger, quitting laziness and staying up late, and developing good health. Lifestyle habits and avoid these bad habits increase the pressure on the blood supply to the brain and affect the health of the body.
