A while ago, my friend asked me if blood pressure had anything to do with fainting. I said, “Yup”, and she said, “Explain it to me later”. So welcome to Later, everyone!
What is fainting?
For the people who don’t know, fainting is the loss of consciousness due to a lack of oxygen reaching the brain. Fainting also has a medical name, Syncope. It’s pronounced sing-co-pee (English is a strange language).
Why do people faint?
Biologically, people faint because they experience low blood pressure (though, there can be other cardiovascular problems). This isn’t necessarily of medical concern; you can have low blood pressure for several reasons. For example, if you are dehydrated, you have less fluid in your blood stream. This means that you have a lower blood volume in your blood vessels, which results in a lower blood pressure.
When you have low blood pressure, your blood vessels lose their tone and are unable to deliver blood cells to your brain as efficiently as it would if you had normal blood pressure. This results in your brain receiving less oxygen. The lack of oxygen is what makes you lose consciousness, since oxygen is required for the sustenance of your brain cells, not to mention your other cells!
So what can I do?
Stay hydrated folks! That’s one of the simplest ways to maintain a normal blood pressure :)
And that’s how blood pressure is related to fainting!
