Why Do We Cry?

Crying can either be a good or bad thing. You can be so happy that tears run down your face, or something sad just happened. Believe it or not, tears are healthy and help protect your eyes. They come in different types and there’s more to them than just water. Read on to find out about why we cry.

Tears Help Protect Your Eyes

According to Science Direct, “the tear film is the barrier between the vulnerable surface of the eye and all kinds of germs, allergens, and irritants in the air.” It is composed of three layers: a mucous layer that lies directly on the cornea, an aqueous layer that’s made up of saltwater, and an outer oily layer that keeps other layers from evaporating.

What does these three layers do? Work together to keep our eyes lubricated, clean, and free of harmful germs. When you get something in your eye, you blink. Tears wash the debris out of your eyes.

The Production & Drainage of Tears

The glands in your eyelids produce new tears and ducts drain excess tears out. Have you ever wondered why you get a runny nose when crying? That’s why.

Tears Do Help You Feel Better

Tears come in two types: reflex tears and emotional tears. According to the American Academy of Ophthalmology, “reflex tears are an overflow of basal tears whenever our eyes need to flush something out.” Picturing yourself cutting onions.

Do you feel better after you’ve cried? Emotional tears clear out some of the chemicals that build up due to stress. You’re purging harmful chemicals and triggering hormones to regulate pain.

Dry Eye

Dry eye is a common condition in which a person doesn’t have enough quality tears to lubricate and nourish the eye. Tears are essential for maintaining the health of the front surface of the eye and providing clear vision.
