Deep breathe in and breathe out: Too much of carbon dioxide causes one to yawn. To avoid such yawns try to inhale deeply, hold in for some time and breathe out all the air out of the lungs. This will help you from the yawns.
Try suppressing yawns: When you feel a yawn coming, keep your mouth closed. Clench your jaws and swallow the yawn that was coming. In case you cannot, just hide your mouth with your hands.
Excessive yawning can occur due to asthma or other problems of the lungs. In such instances, you are advised to see your doctor at the earliest.
