Well... Yawning is perfectly healthy and most likely normal. This medical mystery is a very natural action.

Why? Well i think that you usually yawn when you're tired, right? So when you're tired you are obviously breathing slower. The air is more CO2 (Carbon Dioxide) Right? So when you breathe the air you take in is mostly CO2 at any given time of the day. So anyway you breathe in and you breath out. A little less air comes out then what was taken in. Since you are breathing so slow some CO2 is still in your lungs. Then your body knows that their is extra CO2 in your lungs and you need to get rid of it. So your body pushes it out in one big breath. Causing the yawn.

Is it HEALTHY? YES!!! it's perfectly normal! No harm ever came to you while yawning did it? No, I didn't think so.
