Running is our most common form of exercise. Be careful when running, don't compare with the exercisers around you, otherwise it will easily make our eyes black. Then why can't you stand up after running?

My eyes are black after running, and I can't stand it 1. After running, I feel dizzy and my eyes are black. The most common condition is insufficient blood supply to the brain After strenuous exercise, the heart rate will increase, blood pressure will increase, and cerebral vasospasm will cause short-term cerebral blood supply deficiency. The ophthalmic artery is also a branch of cerebral blood vessels, and dark circles will naturally appear.

Patients should strengthen physical exercise to enhance their physique, but not strenuous exercise. When the above symptoms appear, stop exercising immediately and rest on the spot until the symptoms are relieved. If the symptoms persist, you must see a neurologist in time for blood pressure measurement, blood sugar, blood routine examination, electrocardiogram, head CT and other examinations, and timely treatment after a clear diagnosis.

Disease analysis:

Black eyes during running are mostly due to drastic changes in respiratory and cardiac functions during exercise, resulting in changes in blood supply.

Suggestion:

Short-term insufficient blood supply to the brain causes dizziness, blackness in front of eyes, and syncope can occur in severe cases, which is called exercise syncope.

1, insist on exercise, strengthen physical fitness and strengthen diet and nutrition.

2. It is not advisable to do strenuous exercise on an empty stomach. Don't stop after the sprint. Keep jogging and take a deep breath for a while.

3. When standing for a long time, always alternate lower limbs. Don't stand up suddenly after a long time, stand up slowly.

4. Those who are weak after a long illness will not take part in strenuous exercise for the time being.

After running, dark circles can't stand 2 1, and exercise will affect blood pressure. In the process of running, it may cause a short-term change in blood pressure, leading to a decrease in cerebral blood flow, thus causing blurred vision.

2. When the head vibrates too much or moves violently for a long time, it can lead to an increase in intraocular pressure, which can easily lead to abnormalities of vitreous body and retina, and even lead to a decrease in vision.

3, diabetic retinopathy, in the early stage of diabetes, there will be different degrees of visual decline (light and heavy, repeated changes), and the visual damage will gradually increase in the later stage, which will lead to blindness in severe cases.

4. Hypoglycemia during running. Because the blood sugar level of normal people fluctuates in the range of 3, 3~8 and 3 mmol/L. When the blood sugar level of human body is lower than 2 or 8mmol/L, people will have hypoglycemia reaction, and blurred vision is one of the symptoms.

5, long-term ultraviolet radiation. The main ultraviolet light source in nature is the sun, and the eyes are the most sensitive parts to ultraviolet light, so it does great harm to people's eyes. When running outdoors for a long time, if your eyes are exposed to ultraviolet rays for a long time, it is easy to cause eye pain and blurred vision.

6. When watching TV on the treadmill, the eyes will be constantly adjusted to match the change of movement position, resulting in much more eye muscle movement than usual, thus causing eye fatigue and blurred vision and pain. And it is likely to distract your attention, and you will get hurt if you are not careful.

Black eyes can't stand the three signs before sudden death after running.

1, flustered

Palpitation is often a subjective feeling of increased heart rate. The irregular increase of heart rate is usually the result of tachyarrhythmia. Most arrhythmias are less dangerous and will not lead to sudden death, but if they are frequent ventricular arrhythmias, there is a risk of ventricular fibrillation.

2. The heartbeat is too slow

The beating of the heart is initiated by specific pacing cells. The dysfunction of pacemaker cells will slow down the beating speed of the heart and even lead to cardiac arrest in severe cases. Pacing cell function will gradually deteriorate with age.

3, syncope

Syncope is an important precursor of sudden death. Most syncope is due to the sudden slowdown or stop of heartbeat, resulting in insufficient blood supply to the brain. Common causes include sinus node disease, atrioventricular block and vagal hypertonia.

4. Unknown fatigue

Sudden death is not a patent for the elderly, but also happens to young people. It is normal for many young people to bear heavy work pressure and fatigue. However, if there is unexplained fatigue, or accompanied by chest tightness and edema, we should be alert to the occurrence of sudden death, which may be caused by myocarditis or cardiomyopathy.

5, black eyes, numbness of limbs

Stroke is also an important cause of sudden death. Some strokes have a sudden onset, and limb paralysis and high blood pressure will occur within a few minutes. In this case, patients can save lives if they seek medical treatment in time. However, some of them are slow and have only mild symptoms in the early stage, and patients don't care. Once it progresses, it may lead to sudden death, which requires more attention.
