Question

– why do we yawn after seeing someone else yawn?

In: Biology

Answer 1

There is no scientific consensus for why we yawn at all, let alone why yawning seems to be “contagious.” We know that it is, that’s been proven through a number of studies, including several that involved people merely looking at pictures of yawning. But there’s still no explanation for it.
