When you yawn, your mouth opens wide, and air rushes in. Scientists have looked into what causes the noise during a yawn and found that it’s actually quite complicated. Why do I make noise when we yawn ? Here we are going to explore why it happens. We will also touch on why yawning is contagious.

Reasons for Why Yawning Noises:

There are 5 reasons why people make a noise when they yawn:

  • The air that is exhaled from the lungs during a yawn is noisy because it forces the mouth and nose to close tightly. This causes a build-up of air in the oral cavity and nasopharynx, which is then expelled with a sound when the mouth and nose reopen.
  • Yawning also causes a vibration of the palate, uvula, and pharynx due to the sudden influx of air. This vibration creates the noise that is associated with yawning.
  • Some people make a noise when they yawn because they accidentally inhale some saliva into their lungs while yawning. This often happens when you open your mouth too wide while yawning, which can cause some of the saliva in your mouth to be drawn into your lungs.
  • The noise may also be caused by the tongue, which can make a clicking sound when it hits the roof of the mouth during a yawn.
  • Finally, some people produce more noise when they yawn due to how their vocal cords are configured. This is why some people’s yawns sound louder than others.

How Can We Avoid Making Noise when We Yawn?

There are a few ways to avoid making noise when you yawn:

Pinch your nose shut and open your mouth:

When you yawn, your mouth opens wide automatically. To keep the noise down, pin your nose shut while doing it. This way, the air will escape through your teeth instead of making that pesky “ah” sound.

Cup your hands around your mouth:

If you cup your hands around your mouth when you yawn, it will help muffle the noise. It’s not foolproof, but it can help.

Cover your mouth with a tissue:

If you have a tissue handy, why not use it to cover your mouth while you yawn? This is probably the best way to keep the noise down.

Cover your mouth with a tissue:

Cover your mouth with a tissue when you yawn if you’re in a public place and don’t want to be too conspicuous.

Bite on a pencil or pen:

Putting something in your mouth while you yawn can help keep the noise down. Biting on a pencil or pen is a good way to do this.

Swallow hard before you yawn:

This is probably the most effective way to keep from making noise when you yawn. Swallowing hard before you yawn will help close off your throat so that the air can’t escape.

What Are the Benefits of Yawning without Making Noise?

Yawning without making noise has a few benefits.

  • First, it helps clear your ears if you’ve been swimming or scuba diving and have water trapped in your ears. Yawning also helps to increase blood flow and oxygen intake to the brain.
  • Additionally, yawning without making noise can help reset your nervous system after being startled or stressed.
  • Finally, it’s just a good way to release tension and eliminate any built-up energy. It can be very relaxing!

Why Do We Yawn When We’re Tired or Bored?

Yawning is a reflex that is caused by the activation of stretch receptors in the walls of the blood vessels in your sinuses. When these receptors are activated, they send a message to the brain that causes the muscles in your neck and jaw to contract.

This pulls air into your lungs, resulting in a yawn’s characteristic sound. We yawn when we’re tired or bored because it’s one way to get more oxygen into our system. Yawning also helps to cool down the brain.

How Can You Stop Yourself from Yawning when You Don’t Want to Yawn in Public?

Ways to stop yourself from yawning when you don’t want to yawn in public:

Keep your mouth closed:

This is the most basic way to stop a yawn. When you feel a yawn coming on, simply keep your mouth closed and pinch your nose shut.

Yawn with your mouth open:

If you can’t keep your mouth closed, another way to stop a yawn is actually to yawn with your mouth open. This will help dissipate the yawn’s energy and prevent it from happening.

Take a deep breath:

Another way to stop yourself from yawning is to take a deep breath and hold it for a few seconds. This will help to oxygenate your body and distract you from the yawn.

Drink a glass of water:

Sometimes, yawning can be caused by dehydration. If you’re feeling thirsty, drink a glass of water to help stave off the yawn.

Chew gum:

Chewing gum is a good way to keep your mouth busy and distracted from yawning.


Scientists believe that yawning allows our bodies to regulate brain temperature. When we yawn, the facial muscles pull air into our lungs and circulate it all throughout our bodies. This cooling effect is thought to help keep our brains from overheating. So next time you see someone yawning, don’t be so quick to judge. They’re just trying to stay cool!
