What does yawning do for the body exactly?

I tend to yawn all the time. and get this, when I am tired or something, I will honestly just sit back and do some stretching to yawn on purpose for 15 minutes straight. because for some reason I’ve been noticing after yawning for that long, I get back a lot of energy!! Why is this?
All inputs appreciated thank you!
