The reason for tears to be released when you yawn.
The tears are secreted by the "lacrimal glands" located just inside the eye lids next to the nose. These glands secrete the fluid into the "lacrimal bag" where it is then released through the "lacrimal ducts" into the lining of the eye lids to keep the eye moist.

All eyes water while you yawn, a few extra then others. Maybe you rub them too difficult after to wipe the tears. Just due to the fact men and women get a brownish streak underneath their eyes does now not imply they do medicinal drugs. I bet you can not give up what men and women consider, however you can not rather give up your eyes from watering both.
