Many people tend to fight the onset of tears, when crying is in fact a natural and beneficial response to several common emotions such as grief, sadness, dejection, and even joy. Tears are triggered by our emotions, but they are also a practical and protective reaction from the body. We produce three main types of tears.

Basal tears are in our eyes all day. Basal tears are functional, lubricating tears that help improve our vision, focus, and fight against infection. A protein called lysozyme is present in basal tears. This protein protects against viruses, bacteria, and fungi. Basal tears contain oil, mucus, salt, and water. The oil prevents the tears from evaporating and blinking spreads a layer of basal tears on the eye’s surface.

Reflex tears are our eyewash tears. These are triggered by environmental irritants such as dust, smoke, and wind. These tears flush out any irritating material for our eyes. These are also the tears produced when we cut an onion.

Emotional tears flood our eyes in response to strong emotions and are similar to basal tears in chemical makeup but also contain stress hormones and natural pain relievers.

Crying has a number of other proven benefits as well. Crying has a self-soothing effect which helps us to calm ourselves, regulate our emotions, and return us to a more neutral emotional state within a certain period of time. Deep belly breaths from crying and sobbing regulate our heart rate, blood pressure, and breathing - all of which aids in recovering from stress.

Crying can cause our body to produce hormones that make us feel better. We release oxycontin and endorphins after we cry, which can help reduce stress, relieve pain, and lift our mood. In other words, having a good cry can improve our mood after we cry. 

Crying is also a way the body rids itself of chemicals that are released in the body to help us cope during times of stress, but can have negative impacts when not processed out of the body. So, if we try to push back the tears or feel shame when we cry, it can have the opposite effect, inducing anxiety, depression, upset stomach, and heart-associated issues.

Crying is also an attachment behavior. Crying signals to others that we need help and support. Most obviously associated with infants and small children, research suggests that crying serves the same functions in adults, facilitating deeper social connections and community support.

The trip was unplanned. I had received a phone call from a close friend telling me his 15 year old daughter was about to die. In a few short hours, my family and I were on the road for a grueling 24 continuous hours of driving in order to be with my friend and his family.  

While driving and praying and crying I looked out my window somewhere in southern Washington and saw the train tracks near the river in the valley below.  On the tracks sat rusty old boxcars, one after another, when suddenly, a series of cars brightened up that morning sky. They had been hit by graffiti artists, but instead of the normal tagging so common in the inner city, these were truly works of art.  Each car was decorated with beautiful colors. Each car stepped off the tracks and opened up a new world of possibility and color. At that moment, I remember being struck by the raw beauty painted upon the rusty shells of the old cars.

Russell famously wrote this about the meaning of life:

"That Man is the product of causes which had no prevision of the end they were achieving; that his origin, his growth, his hopes and fears, his loves and his beliefs, are but the outcome of accidental collocations of atoms; that no fire, no heroism, no intensity of thought and feeling, can preserve an individual life beyond the grave; that all the labours of the ages, all the devotion, all the inspiration, all the noonday brightness of human genius, are destined to extinction in the vast death of the solar system, and that the whole temple of Man's achievement must inevitably be buried beneath the debris of a universe in ruins--all these things, if not quite beyond dispute, are yet so nearly certain, that no philosophy which rejects them can hope to stand. Only within the scaffolding of these truths, only on the firm foundation of unyielding despair, can the soul's habitation henceforth be safely built."
