What does frequent yawning mean?
Most likely because you're tired or really, really bored. Have you ever noticed yourself yawning at those times? It's usually because you start to breathe slowly when you're tired or bored, and not enough oxygen gets to the brain. So, the best way to get that air, is to take a deep breath, which is known commonly as a yawn.

Asked in Yawning
Why does a person yawn when they are tired?
As per the theory of yawning, when the person gets tired or bored, the amount of carbon di oxide in the body of person increases and oxygen level decreases. This leads to low blood flow to the heart and brain, so to increase the oxygen level the person yawns. In the process of yawning more amount of carbon di oxide goes out of the body and the body can take more amount of oxygen
Is yawning contagious?
yawning is contagious only if someone sees you do it ... as a sort of social action. It is not contagious in the disease sense. The physiologic function of yawning is to relieve the imbalance between where the blood flows in the lungs (mainly at the base) and where the air flows (mainly at the apex). Note that this is a problem mostly when you are in an upright posture. Yawning is contagious, at least to humans. Many animals yawn, but only dogs, chimps, and humans are known to yawn after someone else does. There is no conclusive evidence why we yawn to begin with, but it's possible that contagious yawning may have something to do with social bonding and empathy. For example, autistic people tend not to yawn after another person does, and children under the age of four don't do it either. This suggests that yawning after someone else is a sympathetic and social act, similar to unconscious mimicking. When tired, yawning is psychologically "contagious", but not physically contagious in the most common sense of the word.
What cause yawning?
Yawning is associated with tiredness, stress, overwork, lack of stimulation, or boredom. Yawning can also be a powerful non-verbal message with several possible meanings, depending on the circumstances. In humans, yawning has an infectious quality (i.e., seeing a person yawning or just thinking of yawning, can trigger yawning) which is a typical example of positive feedback. Infectious yawning has also been noted in chimpanzees. a reflex of simultaneous inhalation of air and stretching of the eardrums, followed by exhalation of breath. Pandiculation is the term for the act of stretching and yawning simultaneously.Yawning is also associated with tiredness, stress, overwork, lack of stimulation, or boredom.

Another speculated reason for yawning is nervousness and is also claimed to help increase the state of alertness of a person - paratroopers have been noted to yawn in the moments before they exit the aircraft.
