DMaynard Posted June 11, 2010 Share Posted June 11, 2010 Why the heck do we yawn? I know it is when you are tired, but does stretching your jaw actually refresh anyone? And why is it contageous? Even with dogs??? Link to comment Share on other sites More sharing options...

slats Posted June 11, 2010 Share Posted June 11, 2010 Doesn't it have something to do with the body needing more oxygen ? Yes. Although I'm not sure why my body needs more oxygen when I'm bored to death. Link to comment Share on other sites More sharing options...
Jetsfan80 Posted June 11, 2010 Share Posted June 11, 2010 Yes. Although I'm not sure why my body needs more oxygen when I'm bored to death. Ahh, the power of the internet! http://www.coolquiz.com/trivia/explain/docs/yawn.asp Scientists speculate that the onset of a yawn is triggered either by fatigue, or by sheer boredom as, at those times, breathing is shallow, and little oxygen is carried to the lungs by the oxygen-toting cardiovascular system.

Integrity28 Posted June 11, 2010 Share Posted June 11, 2010 Yawning is like a reset to your breathing rhythm... when we get bored or tired and breath shallow, our oxygen balance gets messed up... or something like that.

Thai Jet Posted June 13, 2010 Share Posted June 13, 2010 I yawned reading this thread. Seriously. And can you really make a dog yawn by yawning? I tried it with my cat. She yawns all the time so it's hard to tell if I made her yawn or not . Link to comment Share on other sites More sharing options...
