    Yawning is caused by lack of oxygen to the brain, excessive yawning could mean you have a respiratory problem, or there is something preventing you from getting the proper amount of oxygen. You should probably mention this to a health professional, or visit a doctor.

    I highly doubt you are sick there are very very few if none of viruses that cause excessive yawning, get 8-9 hours of sleep per day if you can

    Low oxygen levels in your blood, a yawn is your body's response to stimulate deep breathing.
