Why do I feel dizzy and my eyes go dark when I wake up?

In real life, many people have experienced dizziness and blacking out when they stand up after squatting for a while. So what is wrong when you experience symptoms such as dizziness and black eyes? If you squat for too long and then stand up suddenly, this is generally not a disease. It is often caused by the blood vessels being forced when squatting, resulting in a temporary lack of blood supply to the brain.

I feel dizzy and my eyes are dark. What's going on?

1. When the human body squats or sits for a long time and then stands up suddenly, the blood in the whole body quickly flows to the waist and legs, resulting in a temporary lack of blood supply to the brain. In addition, the functioning of the brain and eyes requires normal blood supply at all times, so even a brief lack of blood supply can cause dizziness and blackouts.

This symptom is medically called orthostatic hypotension, also known as postural hypotension. People with weaker bodies need to pay more attention to it. When squatting or sitting for a long time, do not stand up suddenly and move slowly. What is orthostatic hypotension?

2. When people are squatting, the blood distribution in the body is special. Because the two legs are pressed tightly, the blood vessels are flattened, and the amount of blood reaching the lower limbs is relatively less. Furthermore, the head tilts slightly forward when squatting, so more blood naturally reaches the head. When standing up suddenly, the pressure on the blood vessels in the lower limbs is suddenly relieved, so a considerable amount of blood suddenly flows to the lower limbs, and the brain suddenly suffers from insufficient blood supply, resulting in dizziness. Moreover, blood has a certain weight in the body. If you stand up suddenly, a large amount of blood will rush to the lower body due to gravity, and the amount of blood distributed to the upper body will be reduced, including the blood supply to the eyeballs. This will cause black spots in front of your eyes.

3. Other disease factors cause dizziness. We often hear that anemia can cause dizziness, but suddenly feeling dizzy after standing up after squatting is not necessarily related to anemia. It can only be said that this situation will occur in anemic patients. The cause of dizziness is likely to be related to colds, cardiovascular diseases, cervical spondylosis, brain tumors, neurasthenia, arrhythmias, improper control of diabetes, etc. If this situation occurs frequently and there is no improvement after conditioning, it is best to consult a doctor for a thorough examination and treatment.

4. If there is no organic disease, and if anemia or physical weakness causes insufficient blood supply to the brain, you can regulate your body and improve the symptoms by supplementing nutrition, maintaining a regular schedule, and exercising moderately. Patients should maintain regular sleep of 7 to 8 hours a day, eat more blood-replenishing and qi-replenishing foods, such as donkey-hide gelatin, red dates, peanuts, wolfberries, astragalus, angelica, etc., and insist on running, walking, playing ball and other exercises every day to improve and enhance their physical fitness; before getting up to urinate at night or before getting up in the morning, move your limbs first, and then get up slowly. Do not get up suddenly as soon as you wake up to prevent transient cerebral ischemia. During the conditioning process, pay attention to whether your blood pressure is normal at any time. If it remains normal for a long time, you can adjust it with medication.
