How come when someone faints.......?

Question

......all you have to do is slap them or splash water on thier face and they wake up, but when someone passes out drunk you can't.

Answer 1

"Fainting or syncope (IPA: /ˈsɪnkəpi/ or /ˈsɪŋkəpi/) is a sudden (and generally momentary) loss of consciousness, or blacking out, due to a lack of sufficient blood and oxygen reaching the brain. "

Answer 2

You're talking about two different things, that's why.

Also, there are many reasons people faint. It's not always as easy as "jolting" them back. Typically a person faints due to lack of oxygen, so the body says, "Hey, you aren't getting enough air - screw you, I'm going to do this myself." At that point the body takes over, shuts you down, and allows itself to catch up to a normal breathing pattern.

This is why it is impossible to kill yourself by holding your breath. Eventually the body says, "Okay buddy, you've had your fun, I'm turning you off."

That's a very different experience than consuming so much of a depressant that your body begins to shut down. In this case, it is not a matter of oxygen, but the body actually trying to stop the further intake of what it perceives to be poison.

Answer 3

When someone faints it is a temporary thing that could have been caused by several factors, such as a temporary drop in blood pressure, whereas alcohol is a central nervous system depressant. The alcohol affects several functions in your body and you will not respond as quickly as simply fainting.

Answer 4

faint is an abrupt, usually brief loss of consciousness, generally associated with failure of normal blood circulation while passing out with alcohol occurs when a person feels weakness, physical or emotional distress due to a loss of blood supply to the brain. but to put it short its because when you faint there is no subsatance that is makeing you faint but when you drunk and pass out there is that alcohol affecting you system. thats the explanation i can come up with.

Answer 5

One is a loss of consciouness owing to blood flow or shock and will restore quickly.

Drunkeness is due to the fact that alcohol is a depressant and is a systemic problem

Answer 6

What causes fainting?
Fainting, which is also called syncope, can be related to many different things. More than one thing may be the cause of fainting. Sometimes a specific cause for fainting can't be found.

Fainting can happen when not enough oxygen flows through your blood and into your brain. You lose consciousness, or "pass out," for a very brief time -- just a few seconds or minutes.

A sudden drop in your blood pressure can cause you to faint. Sometimes your heart rate and blood vessels can't react fast enough when your body's need for oxygen changes. This is very common among older people. It can happen when:

You stand up fast.
You work or play hard, especially if it's very hot.
You begin to breathe too fast (called hyperventilating).
You get very upset. Being upset can affect the nerves that control your blood pressure.
You're taking medicine for high blood pressure.
Coughing, urinating and stretching can also get in the way of the flow of oxygen to the brain and may be a cause of fainting. If you faint once during one of these activities, it's probably not something to worry about. But if it happens more than once, you should tell your doctor about it.

If you faint when you turn your head to the side, the bones in your neck may be pinching on one of the blood vessels that leads to your brain. If this happens to you, be sure to tell your doctor about it.

A drop in your blood sugar may also cause you to faint. This can happen if you have diabetes, but it may also happen if you don't eat for a long time.

Some prescription medicines can cause fainting. Be sure to talk to your doctor if you think your fainting may be related to a medicine you're taking. Alcohol, cocaine and marijuana can also cause fainting.

More serious causes of fainting include seizures and problems with the heart or with the blood vessels leading to the brain.

How will the cause of my fainting be found?
Your doctor will probably want to talk to you about exactly what was happening when you fainted. He or she may ask you for details about how you felt right before and right after you fainted. Your doctor will probably also want to examine you.

What should I do if I think I'm going to faint?
If you feel like you're going to faint, lie down. If you can't lie down, sit and bend forward with your head between your knees, to help get the blood flowing to your brain. Wait until you feel better before trying to stand up.

Should I see my doctor if I faint?
You probably don't need to go to your doctor if you have only fainted one time and you are in otherwise good health. Fainting is common and usually not serious. However, if you have serious health problems, especially heart-related problems, high blood pressure or diabetes, you probably should see your doctor. See your doctor if your fainting is associated with any of these features:

Irregular heart beat
Chest pain
Shortness of breath
Sudden onset (no warning signs)
Blurred vision
Confusion
Trouble talking
Fainting when you turn your head
Fainting more than once in a month
