Scientists now claim humans yawn to cool down the brain

[Shawn Knight]

Yawning – it’s something that happens on a semi-regular basis for most and is typically associated with being tired. The act was commonly thought to draw more oxygen into the lungs to make you feel less tired but new research suggests that may not be the case.

Scientists now believe that humans yawn as a way to cool down our brains. The act increases your heart rate, blood flow and the use of muscles in your face – all of which help to cool the brain. I’ll leave it up to the clip above to explain why our brain gets hot in the first place and why yawning is contagious.

Damn, I need a new heatsink to cool down my brains before the zombies notice my over-heating brains.

That’s upsetting I hardly ever yawn. Time to start using my brain to see if I hit the thermal throttle aka yawning.

1. I think a LOT. 2. The Video was not exciting. 3. I do not have Autism, ADD, etc.
4. I Program Computers and do Tech Support, sometimes 18 hours a day (I try to avoid that when I can).

I guess the yawn-o-meter needs to go up to 100 for some of us. I do yawn from time to time

Mmmm... this is odd, I've never yawned when I'm head on something, that explains a lot

Couldn't watch the video from the company computer *yawn*

If you want to break the world record or become smarter than Einstein, then use LN2 when you overclocking your brain

Bogus yawn research is performed to get cool government grant money.

If that's true why does yawning accompany a desire to sleep?
