Question

Does yawning help us in anyway

Answer 1

Yawning, then, would be an involuntary reflex (something we can't really control) to help us control our oxygen and carbon dioxide levels. Sounds good, but other studies have shown that breathing more oxygen does not decrease yawning. Likewise, breathing more carbon dioxide does not increaseyawning.

Answer 2

Yes yawning help us control our oxygen and carbon dioxide levels in our body.
