Excessive yawning can be a warning sign of an impending heart attack | The Times of India

Commonly yawning is a sign of sleeplessness. But if you keep doing it even on days when you have a sound sleep and are not feeling tired at all, then it can be a symptom of a serious health condition.

Yawning is a mystery in the world of medical science. Several efforts have been made to decode it, but scientists have not gained much success. As per some studies yawning helps to promote blood oxygenation and brain cooling.

It is believed that excessive yawning is related to a vagus nerve, which runs from the bottom of the brain down to the heart and stomach. In some cases, people yawn too much when there is bleeding around the heart. This reflex phenomenon is also linked with stroke. As per studies excessive yawning may happen before or after a stroke. Other symptoms accompanied with it are numbness, dropping lower face, weakness in arm and difficulty in speaking. As per health experts, those who yawn too much during exercise, especially on hot days may be at risk of a heart attack.
