Yawning is a symptom which indicates that the brain and the body of a person requires oxygen and nutrients, and because lack of oxygen supply from respiratory organs to the brain and the body. And this happens when we are sleepy or dizzy, lethargic, and people who are facing death. And yawning is activity of inhaled the air deeply through your mouth, not by mouth to breathe deeply as usual!!!
Because the mouth is not an organ that is prepared to filter the air like a nose. So, if the mouth remained open while yawning, then enter also various types of microbes and dust, or lice along with the entry of air into your body. Therefore, come the glorious Nabawi instructions so that we against “yawn” as strong as our ability, or even close our mouth when we yawned with our right hand or even with the back of our left hand.
Sneezing is the opposite of yawning that is strong exhale of the air, along with jolt from two holes: the nose and the mouth. Then it will be drained from the body along with a sneeze is a number of things such as dust (something very small, in the air, which is only visible when there is sunlight), or lice, or microbes that sometimes enter into the respiratory organs.
Therefore, naturally, sneeze came from the Ar-Rahman (Gracious), because it is a great benefit to the body.
