THIS IS WHAT HAPPENS TO YOUR BODY WHEN YOU FAINT

Fainting or losing consciousness is an unpleasant experience for the people who faint as well as for those around them who watch the whole thing and wonder what to do to help. Have you ever wondered what happens to your body when you faint? The YouTube channel SciShow gives us an answer to this question and it’s quite interesting. Fainting happens due to an error in the nervous system which doesn’t let enough oxygen to our brain. Oxygen reaches our brain through the blood, and if this process is interrupted or slowed down for some reason a person faints or losses consciousness.

Although there are a number of medical conditions and reasons why a person may be fainting, today we’re going to talk about the kind of fainting which makes someone drop at the sight of blood. This kind of fainting is called vasovagal syncope, which happens due to some inappropriate neurological response. It’s manifested through sudden blood pressure drop, accompanied by paleness, nausea, vomiting, difficult breathing, inability to urinate and many other symptoms. This type of fainting most often affects younger people and happens as a result of an injury or trauma.

This condition was named by the nerve which provides oxygen to the heart, lungs and abdominal organs. But luckily, this nerve is also responsible for a fast reset after shock or trauma. In order to calm down your body it slows down your heart and widens your blood vessels but it can sometimes “overreact” which can in some people result with fainting due to insufficient oxygen flow to the brain. Here’s a short video explaining the process in detail:
