IT starts with a tingling, itch-like sensation at the back of the mouth, develops into a deep intake of breath, followed by an equally resonant exhalation -- often to the accompaniment of a satisfying groan. To the medical profession it is a "brainstem-mediated bodily response"; to anyone else it's a yawn. Most animals with any backbone yawn spontaneously but only humans, chimps and possibly some species of monkey suffer from contagious yawning -- when the sight or even thought of someone else yawning starts a chain reaction. This occurs when we see or think about another person yawning; there are several reasons put forward as to why it happens. The most accepted is that we see/think about a yawn, and our subconcious automatically starts doing it.
Yawning is not a disease.
Yawning is contagious.
They are contagious in the sense that other people may start laughing or yawning when they see you doing it, but they are not diseases. I thought that because contagious is derived from the Latin "tangere" - to touch, that both laughing and yawning were infectious. I'm not 100% sure though and would welcome a more knowledgeable answer.
When you look at someone while yawning you will probably yawn.Some people think it's 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.

Yes, it is common for people to feel sleepy or have the urge to yawn when they see or hear someone else yawn. This is known as contagious yawning and it happens due to the activation of mirror neurons in the brain, which mimic another person's action, in this case yawning. Contagious yawning is believed to be related to empathy and social bonding.
yes because I've done it before with my mom and my Friend in the car. First i yawned then my mom because i was sitting in the front seat, then my Friend yawned so yes yawning is contagious.
Study shows yawning isn't contagious but the fact we have a circuitry system that makes us want to mimic.
An example of contagious behavior is yawning. When one person yawns, it often triggers others around them to yawn as well, even if they weren't feeling tired before. This is thought to be a natural response related to empathy and social bonding.
