African are so blessed with many cultures and etiquettes. The ways and manners we do things matter a lot in African societies . It must not be done with carelessness hence, it will be termed with certain behaviors.
Honors and respect are more cherished in my mother land. The way we behaved determines the way we will be addressed.
There is etiquette which is done during yawning. Mouth should be covered while doing that.
Apart from African believes, the western culture also adopt the covering of mouth while yawning.

What do I mean by yawning. It is an involuntary action/habit done by opening mouth and ear to allow in flow of oxygen and releasing out of carbon dioxide to relief us from drowsiness , stress, tensions ,boredom and fatigue. When done frequently, it can be termed as lack of sleep or as a result of hunger.
Have you experienced a situation whereby you yarn and the people around you do the same thing?
Have you witnessed a situation whereby you are in a library or class room, one of you yarned and before you know it, the whole class has done the same thing?
If your idea is narrow about this, you can experiment it on your own.
You might even yawn as you are reading this post. Yawning came whenever it is being discussed.
I know you will keep wondering on what could have caused this endemic action.
Relax back and grab the reasons behind it
There's more to yawning than what most people think. There are several theories behind it. Here are the four most common theories responsible for it.
The brain-cooling theory: this is talking about cooling down of the brain it is known that cool brains can think more clearly and effectively, hence yawning is developed to keep us alert.
The physiological theory: This is when we yarn to draw in more oxygen or to remove carbon dioxide.
This theory helps explain why we yawn in groups. Larger groups produce more carbon dioxide, which means our bodies would act to draw in more oxygen and get rid of the excess carbon dioxide.However, if our bodies make us yawn to draw in needed oxygen, wouldn't we yawn)
The Evolution theory:
There's a thinking that yawning started from our ancestors who used it to show up their teeth and intimidate others. It serve as a sign for us to change what we are doing.
The boredom theory: it is done to remove boredom. But much justification are not revealed here.
OK now, let's check our why seeing someone yawn might make us yawn as well.
It is as a result of autism which is a disorder that affects a people social interaction method, it is the ability to empathize with others. The autistic person lack of yawning when watching others do so. This could indicate that they are less empathetic. The non autistic person yawn more frequently compared to autistic person.
I hope this is helpful.
