A yawn is deep involuntary breath from drowsiness, lack of stimulation or boredom. The reflex consisting of the simultaneous inhalation of air and the stretching of the eardrums, followed by an exhalation of breath.
HUMAN YAWNING
Yawning (oscitation) most often occurs in adults immediately before and after sleep, during tedious activities and as a result of its contagious quality.
Yawning doesn't always necessarily mean you're tired, it also means your body needs more oxygen.
When you yawn, you take in three times more oxygen than you do in a normal breath.
Describing how he begins his day, Benito Mussolini said in 1927: "My sleep is like that of a babe. It is profound, undisturbed and therefore extremely reposeful. I instinctively stretch and yawn when I wake, and, as quick as a flash, I am out of bed. My day has begun. I never stay in bed a moment after the yawn."
Yawning and stretching at the same time is called "pandiculating." It's very important in waking up our nervous system.
If you touch your tongue while yawning, it can stop the yawn.
Psychopaths aren't affected by the contagiousness of yawning.

Psychopaths aren't affected by the contagiousness of yawning.
People with autism are less likely to catch yawns. The more severe their condition, the less common the behavior gets.
An animal’s yawn based on how large their brain is. The bigger the brain, the longer they will yawn.
Dogs will yawn in order to express that there is a conflict of interest between their own ideas or desires and those of their owners.

Some animals yawn as a warning signal. Baboons, for instance, yawn to threaten their enemies, possibly by displaying large canine teeth.
Snakes yawn regularly as a way of realigning their jaws or adjusting their bite after they've swallowed a large meal.
The only non-mammal animal that is affected by the contagiousness of yawning is the parakeet.
