what happens when you faint?

Question

can you die if your passed out for too long?

Answer 1

You hit the floor.

I know of two causes for fainting - redout and blackout.

Redout is too much blood and oxygen in your brain. It happens to jet pilots when they do negative-G maneuvers. I think it over-oxygenates the brain.

Blackout is the opposite. It's when you don't have enough blood or oxygen in your brain. This happens to me in book stores often. I kneel down for a long time, reading through a book on the bottom shelf, then when I stand up, I 'tune out' For a minute, my body forgets how to distribute blood between my legs (which have fallen asleep), and my brain (also needed to keep me standing). I have come to call this "Barnes and Noble Syndrome".

So the mortality factor is simply a matter of the conditions that caused it, and whether they continue. Often, the act of passing out alleviates the problem, and you come to in a few seconds. But if a Jet Pilot's controls are jammed, and he is subjected to excessive G's (in either direction), it could be fatal - even before the plane crashes. Or if there is a

When people faint at the sight of blood, the (conscious or subconscious) reaction in the brain that caused the blood pressure imbalance is shut off with the rest of the brain. Then blood flow can continue as normal.

Answer 2

basically, you lose consciousness and fall down. No, you cannot die from fainting. There are other reasons that can cause loss of consciousness, some of those you can die from, but not from just fainting.

Answer 3

Your body does not send enough oxygenated blood to your brain so your body shuts down (and you pass out). This will not kill you, but might be a sign of some other condition going on...so it might be worth checking out with a doctor. Hope this helps!

Hello

Passing out actually is an action of the nervous system to keep you alive, you fall on the floor and blood gets to your head easier and you breathe automatically thanks to your nervous system.
