Welcome To Wordless Wednesday At Create With Joy!
Why Do We Yawn?
I’m sure that when you were young, you were taught that it’s impolite to yawn in front of others – and that if you do, you should have the courtesy of covering your mouth with your hands. But what if you do not have hands – and your parents forgot to tell you to cover your mouth with your paws?
Did you know that yawning is not unique to humans – or even cats and dogs – but it occurs in most vertabrates? Popular to common belief, yawning isn’t just a sign of boredom (although research shows that people do tend to yawn more when bored). Yawning is an essential bodily function that helps us to cool down our brains and increase oxygyn levels to the brain. Beware of excessive yawning, however, as this can be a sign of one of several serious medical conditions!
It might surprise you to learn that humans begin to yawn after 11 weeks of conception – in other words, babies begin yawning while still in the womb! The average yawn lasts for 6 seconds, with men yawning longer than women.
Our heart rates can increase significantly while we are yawning – by as much as 30%. And, yawning is contagious – studies have shown that when someone in a room yawns, within the next 5 minutes, as many as half of the people in the room might be inclined to follow!
Many people believe that there may be more to a cat’s yawn than just these basic biological functions, Cats may use yawning as a form of communication to diffuse conflict and to help protect themselves when they are in potentially threatening situations.
Cats may also yawn as part of their comfort routine when they stretch themselves, as yawning for them involves the movement of a good part of their bodies. A few animal observers have noted that cats tend to yawn and stretch when they wake up but rarely yawn when they are tired.
