Tears send signal to …….

Scientists, psychiatrists, and anthropologists have researched deeply  , here are some findings

  • Babies average generally cry every day for 3 to 4 hours. Babies cry for many reasons, including hunger, discomfort, fatigue, discomfort, fear, pain, loneliness, and genuine peril. Any baby who cries for more than 3 hours a day for 3 weeks (and for no reason at all) may have the dreaded colic.
  • A woman’s tears send a particular chemical signal to men. One of the things this signal does is it causes a dip in male sexual arousal, which is an involuntary yet interesting means of nonverbal communication between the sexes.
  • The size of the tear disparity between genders is often cultural. Women in wealthier Western cultures cry more frequently than women in other countries. Simply put, excessive emotional crying is a first-world problem of sorts.
  • Complications gets formed due to the blocking of tear duct . Blocked tear ducts can result from aging, injury, cyst, inflammation or a tumor. This can paradoxically cause excessive tearing and lead to infection of the affected eye.
  • “Good” crying feels better. Crying can be a means to catharsis because it helps you release tensions and come to new peace or resolutions about the reason behind the cry. Good cries are often associated with another person soothing the crier.
  • The reasons for women crying more often than men are largely biological. Women have 60% more prolactin in their bodies than men. Prolactin is a protein that affects the endocrine system, which may cause women to cry more often than men. Women also have smaller tear ducts than men, which means their tears more readily spill over and, thus, are more visible than men’s tears.
  • Your nose stops up when you cry because excess tears come out of your nose. Each one of your eyes can only hold about 7 microliters of tears, and a strong crying session causes serious overflow. Those extra tears flood the nasal passages, which creates a runny and/or stuffy nose.
  • According to scientists, emotional crying is a unique human experience, but some people do believe that animals can emotionally cry.
  • A neurological condition called Pathological Laughing & Crying (PLC) can cause involuntary crying at inappropriate times. The condition can be caused by ALS, Alzheimer’s disease, multiple sclerosis, or a stroke.
  • The estimated number of times a woman emotionally cries is 50 times per year. Men do it on average of 10 times per year … although they tend to deny the act on many occasions.
  • Scientists believe emotional tears may be an evolutionary adaptation. Tears can provoke empathy or aid from other human beings. They can foster a sense of unity among a group of people mourning the same loss. There’s also a theory that predators could have helped protect humans from predators
  • Tears are produced mostly by the lacrimal glands located just above the outer corner of each eye; blinking spreads the tears across the eye surface. Tears drain into the tiny openings in the eyelids, called puncta (one on the inside corner of each lid), and then through ducts to the nasal cavity, where you either swallow them or they become part of nasal fluid—which is why you also get stuffy when you cry. If production of tears outpaces drainage, the excess will spill from the lower eyelids, as when you cry.
  • When cut, onions release an enzyme that causes the formation of an airborne chemical that irritates the eyes. New Zealand researchers have produced a tearless onion by inhibiting the gene that makes this enzyme, though it’s not commercially available.
  • “Bad” crying can make you feel even worse. Crying can make people worse because of resulting headaches (from dehydration and tense muscles), dry eyes, and stuffy noses. These side effects outweigh cathartic benefits especially amongst chronically depressed criers who aren’t crying about one specific thing.
  • People cry for three primary reasons. When most of us think about crying, Emotional tears come to mind. Those are the horrible sobbing tears or the merciful happy ones. But there are two other types of tears (both categorized as “lacrimal”), Basal and Reflex. The former type lubricates and cleans eyes to protect vision. The latter are associated with environmental irritations like onions (via the chemical irritant Syn-propanethial-S-oxide) or pollen. Lacrimal tears are essential to clean out debris so you can see better.
