Why Do Our Eyes Tear Up When We Yawn?

Saturday, September 12, 2026

SAEDNEWS: Yawning is involuntary, and its exact purpose is not fully understood. However, one thing is certain: we all do it.

Why Do Our Eyes Tear Up When We Yawn?

According to SAEDNEWS, Tears may appear when we yawn because the facial muscles contract and put pressure on the eyes. If your eyes water excessively while yawning, it could be related to dry eyes, allergies, or other conditions that affect tear production. In this article, we examine why our eyes water when we yawn.

There are several possible reasons why our eyes water when we yawn, although there is no single definitive explanation for all cases.

Brain Cooling During Yawning

A detailed study conducted in 2013 found that there is still no definitive answer as to why we yawn in the first place. Researchers examined several different theories, including the idea that yawning may help cool the brain. They suggested that tearing during a yawn could potentially play a role in releasing heat from the skull.

Pressure on the Face

You may have noticed that the facial muscles contract when you yawn, including the muscles around the eyes. This contraction can put pressure on the tear glands and cause tears to flow from the eyes before we even notice it. If you are naturally prone to watery eyes, you may experience more tearing when you yawn than other people.

People with dry eye syndrome may also notice that their eyes water easily when they yawn. Sometimes, tears may even flow from the eyes as if the person were crying. This change can also be related to other factors occurring at the same time, such as:

  • Cold or dry air

  • Air blowing from fans or air conditioners

  • Irritants such as dust, perfumes, and sprays

  • Allergies

  • Conjunctivitis

  • A stye

  • A scratched cornea

Do Everyone’s Eyes Water When They Yawn?

No. Some people can yawn without shedding even a single tear. Just as dry eyes can sometimes cause excessive tearing, they can also make it more difficult for the eyes to produce tears. If a person generally produces fewer tears, their eyes may not water when they yawn.

There is not enough research to determine exactly how common tearing during yawning is. However, many people experience it at some point. The amount of tearing during a yawn can vary depending on different factors, including a person’s physical condition and environmental circumstances.

When Is Tearing While Yawning Unusual?

Everyone is different, so what is normal for one person may be unusual for another. If you yawn frequently, experience much more tearing than usual, or find the problem particularly bothersome, you may consider it excessive. At that point, seeing an eye doctor is a good idea. Eye doctors specialize in treating conditions such as dry eye syndrome and can help identify and treat the underlying cause of excessive tearing.

How Can You Prevent Watery Eyes When Yawning?

There is probably not much you can do to completely prevent your eyes from watering when you yawn. Treating allergies, dry eye syndrome, or other eye conditions may help reduce the problem. Yawning itself cannot always be prevented, but getting enough high-quality sleep and staying active when you feel bored or sluggish may help reduce how often you yawn.

Why Do Tears Sometimes Make the Eyes Burn?

Tears should not normally cause burning in the eyes, whether you are yawning or at any other time. Burning caused by watery eyes may be related to conditions such as:

  • Eye allergies

  • Damaged or dirty contact lenses

  • Eye infections

  • Dry eye syndrome

  • Blepharitis

If the burning sensation lasts for more than a few days or occurs along with other eye symptoms, you should see an eye doctor for an evaluation.
