People say that crying can sometimes be beneficial. On an emotional level, it can help remove the sorrow and pain from your heart, but scientifically crying is also good for our eyes. Our eyes are a very sensitive body part and tears help to protect them. Tears can express feelings of both happiness and sorrow. They contain 84% water, with the rest being an alkaline chemical component called lysozyme, which protects us from the ever-present danger of bacterial infection.
The presence of water in our eyes helps to moisten them and constantly wipe away any outside dirt. According to a scientific study, a single teardrop is so powerful in terms of its antimicrobial property that it can kill all the germs in a gallon of water. Moreover, when compared against other germ killing liquids, it outlasts them by quite a lot of time.
You may ask: why do we cry? As per the American organic research center and biochemist William Frey, tears help diminish the pain, sorrow, and tension from our bodies, and thereby cause us to feel more relaxed. When we are tense or sad, our bodies secrete a vaporized chemical from the corners of our eyes that stimulates the lachrymal gland. This gland helps remove manganese from our bodies. According to Doctor Frey, while manganese is found in human blood, tears contain three times more manganese than blood. Manganese is the chemical component normally associated with mood swings.
Doctor Frey looked at crying under different circumstances during his research experiments. For example, he showed a group of people some emotional films and then compared the chemical composition of their tears with the tears of people who merely had irritation in their eyes. He found that the constitution of emotional tears and tears caused by irritation or burning were different.
Frey also found that both types tears contains three common components: lucin ancifilin (which relives pain), ACTH hormones (which reveal the presence of tension in the body), and prolactin hormones (which help mammals to lactate.)
Prolactin also plays a very active role in producing tears. Doctor Frey found that adult women have a prolactin serum level that is 60% higher than that of an adult man. This is most likely the reason women cry more than men.
Crying is body’s natural process of keeping our eyes moistened and protecting them from infection by removing dirt and other outside particles from our eyes. Some psychologists even consider crying as a bait to attract potential mates or get sympathy from our peers.
According to science, crying is a natural process, thus the saying that “boys don’t cry” is patently untrue. Everybody on the planet cries. Not crying is a both a mental and physical disease. When a baby is born, the doctor immediately slaps their back to make them cry. Only when the baby begins to cry is it considered healthy.
Crying also helps our overall health by creating pressure in our stomach muscles, which stimulates our appetite. In studies, it has been found that crying loudly changes both the color and constitution of our skin. People who cry less are prone to developing skin infections and boils. Thus, crying once in a while is good for our bodies, especially our eyes.
