Surprise about the reason why many people see blood is fainting

Is it because of weak nerves or any other reason that some of us see blood when we see blood "in the clouds"?

Most people who see blood and wounds feel uncomfortable. However, while the majority only stopped at a pouting face, some people reacted so hard . falling out unconscious!

This has been completely explained by science - due to a phenomenon called: Obsessive with blood.

But firstly what is obsession

Haunting in general - including obsession with blood - belongs to a large group of anxiety disorders.

The source of anxiety disorders is attributed to the conditional response of humans to stimuli after experiencing an injury event.

Haunting generally belongs to a large group of anxiety disorders.

For example, someone who has been bitten by a dog can become scared of any dog ​​they see. Or it may be due to the adaptive mechanism within the body that promotes survival, as many people are afraid of innate spiders that have never seen it before.

Another obsession, that other fear

Obsession and fear are two forms of anxiety disorder , which are similar in fear but they are still different.

Fear is common in everyone, almost everyone has their own fears such as fear of the upcoming presentation, the mouse running in the kitchen . This is the basic emotion that makes us focus on threats, stimulating combat or fleeing reactions.

Haunting on the other hand is uncommon and can be seen as a form of persistent, intense, and overly serious fear for agents that most people feel less intimidating.

Syncope due to obsession with blood is a "1-0-2" reaction .

According to statistics, 3% of us are obsessed with blood . An obsession can be triggered by seeing blood, injury, contact with needles, or some other medical activity related to blood.

Of course, most of us are not interested in falling into these situations, but not as extreme as those who are obsessed. For them, just encountering anything that sticks to the blood, the heart rate and blood pressure will suddenly increase in a few moments but then fall down sharply, causing the skin to become pale, sweating, nausea and finally fainting.

An obsession can be triggered by seeing blood, contacting needles .

The fainting reaction of people obsessed with blood is very special, because heart rate and blood pressure actually decrease but not increase as many other obsessions.

This may seem incongruous, because when fearful, humans must activate " fight or fligh t" status . Meanwhile, fainting makes us lose our defense.

And the hypotheses about this phenomenon

There are many theories that have been proposed to explain the fainting reaction . First , adaptive scientists believe that fainting when seeing blood increases the chance of survival, because blood pressure drops significantly, resulting in reduced blood loss in case of injury.

However, this hypothesis has an unreasonable point because someone faints only in case of contact with a needle or has a small wound, which flows very little or has no blood.

Will you ever disgust a food to the point of fainting when it's better to just leave them out?

The second hypothesis suggests that fainting when blood is seen is an evolutionary mechanism in mammals and is controlled by the same physiological mechanism as the "horrible" reaction. That means, when a person sees his or her blood or another person's flow, it can cause a boycott reaction right inside the body.

But such an explanation is also not feasible, because the feeling of " feeling ugly" and "wanting to stay away" is thought to be an evolutionary reaction that helps people avoid eating pathogenic foods. Will you ever disgust a food to the point of fainting when it's better to just leave them out?

The third hypothesis describes the benefits of fainting reactions during the Paleolithic period, which is a time of many threats. In conflicts, encountering a "stranger holding sharp objects" is linked to the danger of life. And then the fainting reaction (or death) was evolved as a defensive response instead of fighting or running away.

Why do only some people faint when they see blood?

Haunting with blood is also often associated with neurological disorders.

Genetic factors have a great influence on the obsession with blood. Many cases of obsession with family history with many members have also been. This is especially true for siblings.

Haunting with blood is also often associated with other neurological disorders such as depression, obsessive-compulsive disorder, panic disorder . and more common in people with abusive childhood and neglect. , or a serious accident.

Some others faint when they see blood because of their impairment of the nervous system, causing them to faint as a conditional response after suffering multiple fainting injuries.
