Yawning while reading quran
As salam aleikum wa rahmatullahi wa barakatuh, brothers and sisters.
I noticed one consistently repeating act(yawn) while I am personally reading quran or doing group namaz. Everytime, whatever of group prayers in mosque it is, like Asr, Fajr, Isha or Magrib, I start yawning while iman recites exactly Al-Fatiha, like only on that surah. And it goes every rakaat. Or when I sit on bed and start reciting quran(I usually practice it that way, cause bed is most of what is in my room, and as a new to Islam i try to learn more surahs and pronunciate them in arabic) once in every surah I yawn.
Maybe I am too judgful to myself, but it really grew some concerns in my mind about am I actually doing everything right. I tried to search it on Google, and some says that its shaitan's work, while other say that there is nothing wrong and that happens to them sometimes too.
So what is it? Why is it consistent? And is there someway to deal with it, because its not good from my side to stand on first raw and yawn.
P.S. I am really serious to religion, and I don't take it fooly as some may think might be the reason
