Yawning is a natural reflex. It is something that we are able to do from birth and something that we will continue to do for the rest of our lives. Yawning is also something that we have little control over, with our bodies deciding to yawn whether we like it or not.
This often leads to the question of just what yawning is. We cant be completely sure, but there are a few suggestions that seem to make a lot of sense. Here is a selection of the possible reasons, of which one or more may well be true.
1. Bed Time
The most common reason for us to yawn us because we are tired, but why? What does it actually do? One potential reason for it is that, generally speaking, it is a good idea for us to have our body clocks synchronized. It is usually more convenient for families, for example, if they all wake at around the same time as each other.
Not only can yawning be a result of being tired, but it might also encourage other people around us to start feeling tired. It is quite effective but it also has its flaws. For example, if a colleague at work is yawning, it might cause you to start feeling tired at work also.
