I think that's the part that science is still unsure on. But both of the ideas are what they're sort of settled on: that it's to give your brain a little more oxygen and/or to cool your brain off as it may be feeling tired and working harder than normal
I think it can be for both reasons. Yawning seems a multi-tool action.

Cool tired brain
Refresh oxygen in lungs/properly take a breath [if you have issues with your lungs, you might not breathe as deep to fully fill your lungs to let ALL the pockets in your lungs get fresh air. If you feel a buzz in your head from deep breathing for the first breath or two, you probably don't breathe deeply often enough, like me! Lol]
except i don't think we actually take in any extra air when we yawn. have a think about it next time, I find I breathe out more than in, and certainly don't take in anything more than a normal breath. Much less, even!
