What does breathing into a paper bag do?

When you’re feeling nauseous or panicky or the like, people might hand you a paper bag and instruct you to breathe into it, such that the bag inflates and deflates. Does it actually help you feel better? If so, why? What in all the world is that supposed to do?
Seems to me like it’ll just make you pass out.
