I feel dizzy and my eyes go dark as soon as I stand up

Many people may have experienced dizziness and blacking out after squatting for a while and then suddenly standing up. Although this is a common phenomenon in life, it may also be that we already have underlying diseases in our body, such as anemia, cardiovascular and cerebrovascular diseases, etc. Because there are many factors that lead to this symptom, and the underlying diseases may also be different, we need to understand the reasons that cause dizziness and blacking out when standing up so that we can take corresponding measures. Let's take a look at it together.

Basically everyone will have this reaction. This is because after squatting, the blood is concentrated in the lower part. After standing up suddenly, the brain is not supplied with enough blood and dizziness occurs. Therefore, avoid squatting for a long time. You should stand up slowly after squatting to give the brain a buffering period. If it is serious, it may be related to anemia

In fact, when you are sitting, squatting or standing, the blood flow is relatively slow, which can be said to be a normal speed. When you squat for a while and suddenly stand up, the blood flow in the body will accelerate, especially the waist and legs. This moment will lead to insufficient blood supply to the brain, which is in a blank state, and you will feel dizzy and black eyes.

Of course, some diseases can also cause this symptom, such as cardiovascular disease, brain tumors, neurasthenia, arrhythmia, etc., but these can usually be discovered during physical examinations, so regular physical examinations are necessary.

The above diseases are ultimately related to the heart, because the heart is responsible for pumping blood throughout the body, so protecting the heart is vital.

Protecting the heart is multifaceted. In terms of work and rest, we must develop good living habits, not stay up late, go to bed early and get up early, and ensure adequate sleep time.

In terms of diet, eat more foods that replenish qi and blood, such as red dates, donkey-hide gelatin, astragalus, angelica, wolfberry, etc.; proper exercise is also important for protecting the heart. People who often lack exercise are prone to heart problems. You can run, brisk walk, practice Tai Chi, play badminton, etc. These are all very important things.
