25 Cute Animals Yawning
Most of the times opening the mouth is a reflex, called yawn, and has different causes. Fatigue, boredom, stress, sleepiness or others yawning (mirror neuron reflex) are usually thought to be in its origin but there are a few theories about it.
- yawning occurs when one's blood contains increased amounts of carbon dioxide and needs oxygen (or expulsion of carbon dioxide) that a yawn can provide.
- yawning is the body's way of controlling brain temperature, needed to increase brain activity.
- yawning, especially "contagious" yawning, may be a way of keeping a group of animals alert and signals tiredness to other members of the group in order to synchronize sleeping patterns and periods.
In animals, yawning can serve as a warning signal to enemies like in baboons, siamese fighting fish and guinea pigs.
The "contagious" yawning can occur across species the reason why you can see your dog or cat yawn after you.
