Yaws may be too frequent an unhealthy sign, and doctors go further, asserting that it may be dangerous, and threatens human health in some cases.
Excessive yawning, especially that occurring more than once per minute, is an indication of some serious health symptoms.
This is a mysterious nervous reaction, which is related to the so-called "vaginal nerve", which extends between the brain and abdomen through the throat, according to the Web site "Medicine".
When the vaginal nerve activity increases, yawning is increased, but this also leads to a decrease in heart rate and blood pressure, and thus serious damage to the heart.
Although doctors do not know the exact cause of yawning, it is associated with drowsiness or fatigue. Yawning in this case works as a technique for the body to wake itself up.
Among these causes are also sleep disorders, side effects of some medications used to treat depression or anxiety, which act as absorption inhibitors.
