Yawning is a normal process but at the same time, it is a mystery which continues to puzzle medics. Excessive yawning could be a signal of serious health hazards. Excessive yawning in both adults as well as children could indicate an underlying problem. Several studies claim that yawning is the body’s effort to cool down the brain. Other theories state that it represents boredom.

Our diaphragm, larynx, thoracic muscles of the chest and the palate of our mouth are all involved in the process of yawning. When we yawn, we open our mouths and breathe in air, filling our lungs. Our eardrums expand and extra oxygen is passed to our brain and other parts of our body. We become alert due to more oxygen and blood supply to our brain. We yawn when we go to bed, when we wake up or when we are bored as in these circumstances our mind becomes less stimulated.

The most common medical ailments related with excessive yawning are anxiety, headache, fatigue, heart problems, shortness of breath, chest pain, tiredness, sleep deprivation, insomnia, sleep apnea and narcolepsy. Some other diseases which can be responsible for excessive yawning include bleeding around the heart, brain tumor, multiple sclerosis, stroke and heart attack.

It should also be noted that we do not always yawn when we are tired. We might run five miles and be completely exhausted but may not yawn. In fact, little supply of oxygen to the brain is not the only deciding factor. As mentioned above, yawning is normal but excessive yawning can be due to certain medical conditions.
