I don’t know if you have seen it or encountered a phenomenon, that is, you fainted after seeing blood. How did this magical phenomenon happen? Welcome to "Knowledge Supplement". Today we will take a look at this magical phenomenon.

Hemophobia For us, our understanding is that we will faint when we see blood. In fact, this is not the case. Generally, people with hemophobia will not faint when they see other people's blood, but they will see their own. Fainting after bleeding, and this is a symptom called vagal syncope, referred to as hemophobia. About 3%-4% of people in the world have hemophobia, and researchers believe that the cause of this symptom is Due to anxiety and stress, when the patient sees blood, the blood pressure suddenly rises and then drops suddenly. When the blood pressure drops, the blood flow to the brain also suddenly drops, leading to syncope. This is what happens when we squat down. It is easy to become dizzy when you stand up suddenly. So far, many researchers have been trying to find a perfect answer to this phobia.

A former colleague of the editor also encountered such symptoms once. At that time, he was cutting fruit and accidentally cut his finger. He immediately covered his finger and spoke calmly. Then the next second, he said He felt so dizzy that he squatted down. Before he could squat down, he fainted. The syncope process only lasted 2-3 minutes before he woke up. He told me that he felt that he had been fainted for a long time, and he He said that he did not have hemophobia. He said that he often killed chickens or watched others kill pigs, but hemophobia turned out to depend on his own blood.

I wonder if anyone has ever encountered such a thing? Welcome to leave a message below, if you like this article, please follow me, and I will see you in the next issue.
