If the human body is something, it is nothing less than a miracle. It carries thousands of processes at the same time without stopping for a second. So, it is only worthwhile to know more about different processes and pay heed to the reason behind each process to get a little closer to your own body. Now, for instance, you are watching a sappy romantic movie or perhaps rummaging through your childhood pictures and then surprisingly tears start rolling down your eyes. It may be a usual experience, but did you ever pause to think why it happens?
According to a few researches, emotional tears have stress hormones that the body pushes out when one cries. It has also been said that crying releases feel-good endorphins into the bloodstream; these are the same endorphins that are released when you exercise or laugh.
Tears can be easily disintegrated into three different layers, namely, lipid layer that comprises oil, aqueous layer that comprises water and mucous layer that comprises mucin.
Every time a woman cries, there is a unique chemical component that releases that men are capable of detecting. According to study published in the journal Science, this chemical component discourages men to feel sexually aroused.
Everyone knows that women cry more than men and so do those who have had a traumatic experience, are anxious, extroverted and emphatic, but researches reveal that some people are prone to crying more than others. The researchers, however, have failed to tell exactly why this difference exists.
Both happy and sad crying has a period of emotional arousal. In fact, regions of the brain that are associated with emotional arousal such as areas of the basal ganglia and hypothalamus are connected to a part of the brainstem referred to as the lacrimal nucleus that causes tear production. Crying helps the body to return to a state of homeostasis after it is aroused overly, whether negatively or positively.
Imagine if you were to be perennially embarrassed on a medical condition that makes you laugh and cry uncontrollably. Pathological laughing as well as crying has been said to be a symptom of stroke, multiple sclerosis, Lou Gehrig’s disease and Alzheimer’s disease.
You know tears as saline water that pours out of your eyes, but according to science there are at least three types of tears:
• Basal tears: these help in cleaning and lubricate your eyes
• Emotional tears: this type of tear does not need any explanation
• Reflex tears: this type of tear drains when your eyes are irritated such as when peeling onion or during a surprise attack by pollen.
Tears are primarily made of the same compositions as saliva. Among other things, they also have proteins, salt and hormones.
