We start yawning before we are born. The frequency of yawning is changed based on the oxygen level of the place we are in. It is considered as a precursor to sleep, but yawning also helps your lungs to get oxygen and your brain to cool, so they can operate more efficiently and keep you awake. It is also related to human moods. If you get bored, you may start to yawn.
Anyway, yawning is good for your health, so yawn away!
