Why Do My Eyes Tear Up When I Yawn

Teary eyes with yawn.
It continuously supplies tear fluid that s wiped across the surface of our eye each time we blink our eyes. Changes in seasons typically can cause changes to the eye due to the amount of humidity in the air and allergens. Firstly it causes pressure to be placed upon the lacrimal duct which in turn causes an increased amount of fluid to be forced into the eyes. So our eyes are supposed.
First it squeezes the lacrimal duct causing more tears to flow into the eye. When we yawn the facial muscles surrounding our eyes pull tight. Secondly it squashes closed the tear ducts that drain the tear film from the surface of the eye. Yawning often increases the secretion of tears because of muscular tension on the lacrimal glands which may simultaneously dam up the drainage system.
This also has an attributing factor to the production of tears in two ways. These glands are working to produce and release tears slowly throughout the day to coat the surface of our eyes at all times not just when we cry. Dryness dirt and infection can each cause your eyes to water. As winter approaches and we increase heat at home work and in the car the air loses humidity which causes the eye to become very dry.
