Once again I believe that the Glory of Gods creation is shown by this phenomena of tears.. If you look at research done on tears it shows that there are different types of tears.. the tears of emotion have more chemicals in them such as hormones and protein. it causes a chemical reaction in the brain which produces more "feel good" chemicals
here's an excerpt from about crying.. you can read the whole thing here

Do you know that crying can be a good medicine for stress? This was found out in a study conducted by experts in America. Based on the research, crying lightens one’s feelings, and people with positive attitude towards crying have a very slim chance of developing ulcer, colitis, and other stress related diseases.
Dr. William H. Frey II, a biochemist, found out that tears have a complex chemical composition more that others think. Researchers found out that there is a big difference between tears caused by joy, anger, and sadness and tears caused by irritation. Based on research, emotional tears contain more substances that our body develops whenever we are under stress. And this is hazardous to one’s health. Because of this, it is believed that crying is an effective way of eliminating wastes in our body because tears remove these stress-related substances. This is the reason why a person feels better after crying. Also, according to reports, tears caused by emotional outbursts have higher protein concentration, which cures emotional stress.
Crying that is triggered by emotional pain is not something that one should be ashamed of, inasmuch as this is but one natural physical process, which is very helpful in easing one’s pain. One psychotherapist said that, “Crying is good for the soul. It opens the lungs, washes the countenance, exercises the eyes, and softens down the temper.” That is why we can say that the Bile is a book that never goes out of fashion. What the Bible said thousands of years ago are being confirmed by science today. And one of these truths pertains to crying.
One more thing, for God, a broken and contrite heart is better than a rejoicing heart. This could be read in
Psalms 51:17.
“The sacrifices of God are a broken spirit: a broken and a contrite heart, O God, thou wilt not despise.”

when biochemist William H. Frey II set out to study crying, he wondered about emotional tears. He knew that nature phases out biological functions that are no longer necessary for survival. He therefore theorized that the ability to shed emotional tears must have a specific physiological purpose. When a two-year search for scientific data yielded no satisfactory answers to his questions, Frey decided to conduct his own research. His formal stud of crying, commencing in 1979 and resulting in the 1985 publication of his book Crying: The Mystery of Tears, began with the premise that emotional tears carry away harmful chemicals produced in response to stress, and thereby play a central role in restoring the chemical balance of the body.
Frey set out to measure and compare the chemical composition of irritant and emotional tears. Aware that specific proteins in tears function as detoxifiers while controlling infectious agents and regulating rates of chemical reactions, he wanted to determine if emotional and irritant tears differed in protein concentration. He found that the protein concentration of emotional tears is 21 percent higher than that of irritant tears. He also discovered that human tears contain the endorphin leucine-enkephalin as well as adrenocorticotropic hormone (ACTH) and the hormone prolactin. Leucine-enkephalin is thought to affect pain sensation and to modulate stress-induced changes in the immune system, while ACTH is released from the pituitary gland and is an indicator of stress.
Perhaps most intriguing is Frey's discovery of prolactin in the lacrimol gland, the gland that produces tears. Prolactin stimulates lactation in the mammory gland, and he speculated that it also stimulates tear production in the lacrimal gland. Frey knew that prolactin levels are 50 to 60 percent higher in women than in men, and he theorized that higher levels of prolactin may lower the threshold of cryin - which might explain in part why women cry more than men. Frey also postulated anotomical differences between the tear glands of men and women, a hypothesis that research has since confirmed.[1]
Frey is quick to point out that while hormonal and anatomical differences may contribute to the dissimilarities between male and female crying, social conditioning plays a major role in defining male crying behavior. He has received letters from men who have not cried since childhood and who have seeking to regain this capacity. Frey himself realized in his 20s that he had not shed a tear since age 12. He then made a conscious effort to express his feelings and was eventually able to cry when moved or upset.
Frey hopes that other scientists will focus their research on the biological aspects of crying. He believes that the study of tears will shed light on the biochemical basis of emotion. "Crying it out" may be more than a figurative expression; it may be a literal description of what occurs as the body rids itself of stress-induced chemicals. Holding back tears, on the other hand, may impede the body's return to equilibrium after stress. As Frey says, "When we teach children to suppress their feelings and not to cry, we do them a great disservice by robbing them of one of nature's adaptive responses to emotional stress."
Thank you Father for creating us perfectly.
