Yawning- Why do you think we yawn? No-one quite knows why we yawn - However there are many reasons: Yawning controls brain temperature; it promotes alertness and readies the body for action, it is a physical response to brain chemical levels associated with mood. It is also a physiological consequence linked to empathy.
Do you realise we yawn on average , in our lifetime 240,000 times?
