Nutrition Nugget: Why Do We Yawn?

Nutrition Nugget! Bite-size, bonus episodes offering tips, tricks, and approachable science. This week, Jenn's answering the question, why do we yawn? There are actually a few theories. First, there is the contagious yawn, believed to be due to the human need for belonging caused by mirror neurons. Secondly, most of the research points to increasing oxygen and blood flow as the reason we yawn. Research also shows that yawns may help regulate our temperature, relieve ear pressure, and soothe feelings of breathlessness. On average, people yawn 20 times per day. All of this is to say that the reasoning behind yawning may be inconclusive, but it does tie in with the oxygen in our bodies. Like what you're hearing?
