Yawning has a powerful impact. If you see someone yawn, or if you think about one, you yawn. Why? Because your body knows it is good! A yawn stretches the jaws wide, increasing blood flow to the neck, face and head. The deep breath pumps the blood, spinal fluid moves, oxygen levels increase, body temperature and metabolism adjust. Yawn again. You have just accomplished something incredible! You are not bored or tired, you are lifehacking!
