Why is it useful to breathe into a brown paper bag when having a panic attack?

Question:

Answers:
It isn't to do with taking in too much oxygen. It's to do with getting rid of too much carbon dioxide.

If you breathe too fast, you are getting rid of carbon dioxide from the blood faster than normal. You might think this is a good thing, since CO2 is a waste product. However, the amount of CO2 in the blood affects its pH - too much CO2 makes your blood too acid, too little CO2 (like if you have a panic attack and hyperventilate) and your blood gets too alkaline. That has lots of other effects, like making you dizzy and tingly and faint etc. If you breathe into a paper bag, you are not breathing in fresh air each time - you are breathing back in some of the air you just breathed out, so you are breathing in more CO2 than normal. This means you don't get rid of it so fast and the blood pH can get back to normal. And because that makes people feel less dizzy and weird it helps them to calm down.

When you are having a panic attack, one tends to taken lots of deep breaths. This can cause one to pass out due to too much oxygen in the blood. Breathing into a paper bag cuts down on the amount of oxygen that goes back into your lungs. It is helpful during an asthma attack as well.

because it helps to normalize your breathing.it helps to even out your oxygen and carbon dioxide levels when you're hyperventilating.

Because you have a tendency to Hyper-ventilate when having a panic attack, and when you do that you get too much Oxygen, so by breathing your own Carbon Dioxide, it has a calming effect. Doing so forces you to actually rebreath some of the air you exhale. This means, you begin to take in less oxygen. Usually in a panic attack, a person takes rapid short breathes, which then leads to the person "hyper ventilating" or taking far too much oxygen too fast.

Breathing into a brown paper bag lessens the amount of oxygen you are forcing into you, allowing you to calm down.

You are breathing part of your breath back in which helps to steady your breathing so you aren't gasping for air.

Psychologically it is well known to help so it helps to get you to calm down your breathing
It gives your mind something to focus on so your breathing can calm down naturally

what signals the brain to breath is carbon dioxide, when having a panic attack, you hyperventilate and cause a rise in oxygen but because you are not getting all the carbon dioxide out the brain is missing the signal to breath and exchange gas, so you get oxygen poisoning, by breathing in a paper bag you level the gases and can hopefully breath normal dang good question i actually learned something from reading peoples answers

When you have a panic attack you breath too fast, thus taking in more oxygen. When you breath into a paper bag you breath in more carbon dixiode which helps stablise the oxygen/carbon dixiode balance in the blood
