The latest research into yawning has shown that it has probably eveloved to increase alertness. The Brain works best when it is cool, if it gets hot we become drowsie and less alert. When we yawn, the temperature in the sinus' at the front of the head are cooled very slightly by the sharp intake of air. Studies showed that perople who continually breathe through their nose, hardly yawn at all! Those who breathe through their mouths yawn more frequently. This is beacuse nose-breathers are actually keeping their brains alert by keeping them cooler (air cooling for the head!). When observing someone yawn, our bodies mimic the action to prevent our OWN brains from getting too warm, even if our bodies are not registering the over heat for themselves.Answered by meher ravikishore, 22 Mar 10:50 am
