Yawning, particularly if you have some congestion due to cold or Allergies, helps even out the pressure on both sides of the eardrum. This allows it to operate properly to transmit the sound waves correctly.
Some studies say that yawning occurs when your brain is overheated. Maybe your hearing decreases because of this heat? Yawning is still a mystery.
Yes, it is common for people to feel sleepy or have the urge to yawn when they see or hear someone else yawn. This is known as contagious yawning and it happens due to the activation of mirror neurons in the brain, which mimic another person's action, in this case yawning. Contagious yawning is believed to be related to empathy and social bonding.
Yawning is not a disease.
if rude and yawning are defined as such i don't see any reason why the act of yawning be rude. yawning is physiologic. would urinating and defecating be rude also?
There are two answers.If you mean you can't hear yourself yawn, then it could mean you aren't yawning loud enough to hear it or you can't hear very well.If you mean you can't hear anything when you yawn, then that could be a problem or a sign of poor hearing. Everybody is different but when I yawn, I can hear stuff around me. Good luck and I Hope this helps =]
Cats hear better then dogs.
The cause in not know.
Yawning too much can prove to be fatal. My aunt didn't sleep for a week, kept yawning, and died. You're in trouble
Yawning is actually putting out (?) the stress in your body, so it is a good thang...
with there huge ears of course elephants can hear better than humans.
Yawning is associated with tiredness, stress, overwork, lack of stimulation, or boredom. Yawning can also be a powerful non-verbal message with several possible meanings, depending on the circumstances. In humans, yawning has an infectious quality, i.e. seeing a person yawning, or just thinking of yawning, can trigger yawning which is a typical example of positive feedback. Infectious yawning has also been noted in chimpanzees. The primary reason behind yawning is to control brain temperature. It cools off your brain, much like a fan cools off the inside of a computer. The claim that yawning is caused by lack of oxygen has not been substantiated scientifically. Some claim that yawning is not caused by lack of oxygen, for the reason that yawning allegedly reduces oxygen intake compared to normal respiration. Another speculated reason for yawning is nervousness and is also claimed to help increase the state of alertness of a person-paratroopers have been noted to yawn in the moments before they exit the aircraft.
"I'm yawning. I'm yawning some more."
