When we are tired we will yawn because at the time we are tired from the work we will not breathe like regularly and we will take yawn to supply oxygen to our body

Answer:
One is that when we are bored or tired, we just don't breathe as deeply as we usually do. As this theory goes, our bodies take in less oxygen because our breathing has slowed. Therefore, yawning helps us bring more oxygen into the blood and move more carbon dioxide out of the blood.
