Do You Faint When You See Blood?
- 7 Months ago
Are you one of those to faint when you see blood? Have you wondered what happens to you? Is it because you are weak or is it something else? Scientists are still researching for the exact cause for this, but, there are 2 theories which have come up explaining why it happens.
According to Tyler C Ralston, a clinical psychologist in Honolulu, it is an evolutionary mechanism which has been passed down through generations. It is believed that, back then, when we were cave people, a genetic variation allowed certain people to faint in response to stabbing or cutting. This made their blood pressure drop preventing them from bleeding to death. Also, this response made them look dead which stopped the other cave people from actually killing them. This is called "Blood-injury phobia".
