I'm gonna start by telling you a little bit about a sea turtle story. That may seem strange, but don't worry, everything will make sense soon. When the mother's sea turtles sneak into the beach at night to put their eggs, if you look very carefully you could see that they shed some tears. Old legend believes that mother turtles cry because they will never get to know their babies. But scientists have discovered that sea turtles are not crying. Instead, they are getting rid of the salt of their bodies, crying some very salty tears. Read more: As sea turtles live in salt water, and their favorite food is the jellyfish, (which are mainly made of sea water!) build too much salt in their bodies, which can be poisonous. Therefore, they need to "bring" this salt from their bodies to survive. If we eat too much salt or accumulate in our bodies, it helps to stir it when we go to the bathroom. But sea turtle kidneys are not as smart as human kidneys, and they cannot get rid of enough salt in the grass. So sea turtles have a special one in each eye, which is twice the size of their brains, that pumps this extra salt into their tears. These turtle tears are so salty, some animals have been seen licking these turtle tears. But what about us humans? If you've ever licked a tear down your cheek, I've probably tasted a little salty. But if our kidneys work better than turtles, and we don't eat jellyfish for breakfast, then why do our tears still salt? Well, all the fluids in our bodies have some salt in them. This salt becomes electricity to help our brains and our brains think. The amount of salt in our body fluids (such as tears, sweat and saliva) is approximately the same as the amount of salt — just below 1%, or about two tablespoons of salt per litre. So our tears are much less salty than the tears of sea turtles, though still a little salty. Read more: 3 types of tears The salinity of your tears can vary depending on your eyes being made. That is right, your eyes—or a part of your eyes called the tear gland, to be precise—make three different types of tears. They are called basal tears, reflex tears and emotional tears. The basal tears keep your eyes wet and stop nasty germs that infect your eyesThe tears of reflection are made when your eyes need to wash something harmful that comes in, such as smoke or a grain of sandemotional tears are the kind that you cry when you feel very happy or sad. The basal tears and the reflex tears have more salt on them than emotional tears, which is important to keep your eyes healthy. Emotional tears contain more of other things, including a hormone (a special type of chemical in your body) that works like a . This could help explain why we sometimes feel better after having a good cry. Read more: The next time you spill a slightly salted tear, you take a minute to think how lucky you have kidneys that control the salt levels in your body, and you don't have to cry salted tears to stay alive, like those mother turtles.

Why are the tears Salty? During particularly sad movies, when you're going through a personal tragedy, or just as you cook an onion-heavy meal, you've experienced the feeling of tears running through your cheeks. Crying is something we've been doing since birth; in fact, it's probably the first thing you did after you came drifting into the world. Given how universal the act of weeping is, some of those tears have undoubtedly flowed into the mouth of each person on the planet, revealing their salted truth! Tears tearing your eyes (Photo credit: pbsubhash/Shutterstock) To be honest, the unusual salty taste of tears remains a source of surprise every time they hit one of my taste buds, begging the question, why? Why do our tears have such undeniable salty flavor? Before we can delve into the full explanation of that question, let us take a look at the composition of our tears. Composition of tears Our eyes are one of the most impressive adaptations of our body, not only giving us the ability to see, but also the complex mechanisms and systems to keep our precious eyes safe. Ensure that the eye does not dry when it is open is critical, so we blink. Every time we close our lids, a thin layer of lacrimal fluid extends across the surface of the eye. These tears "all day" are called basal tears, and are composed of water, lipids, mucin, immunoglobulins, sodium and potassium, among other substances, including a range of ascorbates and urate. Many of the components of basal tears are intended to protect the eye from foreign pathogens or other potential bacterial threats. The second type of tears that form in our eyes are called reflex tears, and as the name implies, they form in response to an intense external stimulus. If you get caught outside in a sandstorm, or maybe touch your eye after cutting a jalapeño chili, these reflex tears are formed to tear off offensive stimuli. The irritants that can trigger such reflex tears can also do it through mucous membranes, nose or mouth, all linked to the same defensive mechanism of tears for quick cleansing. The final type of tears is called psychic tears, and are the tears generated through intense emotional experiences — happiness, pain, exhaustion, fun, etc. Curiously, the pathway through which such "emotional tears" are generated is very different, controlled by the extryl system of the brain, which affects the parasympathetic nervous system, releasing neurotransmitters that activate the lacrimal gland to produce tears! It is not only the path of the generation of different emotional tears, but also the composition of tears. There is a much greater concentration of protein-based hormones, as well as a leucine, leucine-enkefaline, a natural painkiller. Clearly, not all tears become equal, and even when they dry and look under a microscope, it is possible to see the difference between tears generated by a bad break and those generated by a touch of pepper spray! But why are the tears jumping? As mentioned, the basal tears contain potassium and sodium, two of the most important electrolytes we have in the body. For those who do not know, electrolytes are natural salts that the body requires for the function of the nervous system and the transfer of information between different nerve cells. The most important electrolytes (salts) we have in the body include potassium, sodium, calcium, bicarbonate, phosphate and magnesium, among others. When you take your tongue out and taste a little salt in your tears, prove how sensitive our sense of taste is. About 98% of tears are made of pure water, while the remaining 2% contains all the other substances and compounds we have explained before. However, even with such a low level of salinity, their tears make the environment of your eye unpleasant for bacterial growth. His tears are used more often as an extension of his immune system, so the salted presence in his tears makes a perfect sense. In addition, we are salty creatures, with almost half a pound of salt in our bodies at all times, so it makes sense that this very natural fluid would also have some salt concentration. The water in our bodies is inherently salty — albeit less salty than the ocean — and would require a lot of cellular energy to ensure that our tears were 100% pure water. In addition, some of the other salts and ions found in our tears help in the processes of lubrication, protection and healing within the eye. The best thing to have three different types of tears, however, is that the body can react with a proper concentration of salinity and type of tear depending on the threat to the hand! A Final Word The fact that our tears are salted is another argument for the remarkable complexity and interconnection of our bodies. Natural selection has found the most convenient and effective way forward, ensuring that our eyes are protected from damage using compounds already present in body fluids. Even the simplest things, such as tears (reflex) that flow from the corners of your eyes into a convertible journey, tell an impressive history of human evolution and our amazing bodies! is a writer, editor, editor and photographer who got his English and Integrative Biology degrees from the University of Illinois.
