Why do I feel dizzy when I sit down and stand up?

Everyone will experience dizziness when sitting down or standing up in life, and the symptoms will disappear after resting for a period of time. Many people don’t know enough about this situation. In fact, it is related to the speed of blood flow, and it may also be caused by some diseases in the body. Therefore, it is best for everyone to have regular physical examinations. So why do you feel dizzy when you sit down or stand up?

First, why do we feel dizzy when we sit down or stand up? In fact, when we sit, squat or stand, our blood flows relatively slowly, which can be said to be a normal speed. When we squat for a while and suddenly stand up, the blood flow in the body will accelerate, especially the waist and legs. This will lead to insufficient blood supply to the brain, which will be in a blank state, and dizziness and black eyes will occur.

Second, of course there are some diseases that 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.

Third, protecting the heart is multifaceted. In terms of work and rest, you 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.

Why do you feel dizzy when you sit down and stand up? The above content is a detailed introduction to this issue. If the symptoms of dizziness and blacking out when you squat and stand up last for more than 30 seconds, you must see a doctor. People with this phenomenon should not squat for long periods of time. If they have to squat frequently due to work, they can prepare a low stool in advance to reduce the degree of flexion of the lower limbs. When standing up after squatting for a long time, they should stand up slowly to reduce the discomfort caused. They should even pay attention to cleaning the workplace to prevent injuries after falling to the ground due to a brief loss of consciousness.
