yes, you have to take a deep breath, hold it then swallow the air and do that 3-5 times you should yawn very soon afterwords.
You breath in oxygen for your blood to take to your brain so you can think. If you run low on air you become tired and yawn so you get more air to your brain.
Yawning without covering your mouth can be considered impolite or disrespectful in some cultures or social settings. It can also be seen as unhygienic since yawning can spread germs through the air. Covering your mouth while yawning is a way to show consideration for others and maintain good hygiene practices.
Yawning helps to regulate the temperature of the brain, increase oxygen intake, and decrease carbon dioxide levels in the body. It may also help to promote social bonding and empathy between individuals.
When you yawn, its because you're a little inactive. When youre not doing anything, you breathe slowly, not letting enough air get to your lungs. So your brain tells you to take a deep breath, which is what we call a 'yawn' -from Taylor (a 12 year old)
Yawning can dry out the mouth and reduce saliva flow, which allows bacteria to proliferate and release sulfur compounds that cause bad breath. Additionally, when you yawn, you are pulling air and saliva from the depths of your throat, potentially bringing up odor-causing bacteria.
Coyotes breath air into their lungs just like you do.

Yawning is believed to help regulate the temperature of the brain, increase alertness, and potentially serve a social bonding function. It may also occur in response to tiredness, boredom, or as a reflexive response to seeing others yawn.
Birds breath air, just as we humans do, their respiratory system extracts the oxygen which they need to live, again just as we do.
