A 2005 study published in Cognitive Brain Research found that the networks in your brain responsible for empathy and social skills are activated when you see someone yawn. What's more, scientists aren't entirely sure why it's contagious among social animals, such as humans. They are everywhere around us, but some are easier to notice than. Recently, the scientific community has moved toward the idea that yawning is a thermoregulatory behavior that cools down the brain, but its true biological function is still unclear. Phenomena can be defined as observable events that occur in a natural or designed system. Yawning is something you likely do every day, but, oddly enough, scientists still aren't sure why. Some scientists believe yawning is a display of empathy.
