Why tears are salty: an immersion in the world of biochemistry of the human body

Biochemical composition of tears

To understand why tears are salty, you need to change their composition. Water makes up the bulk of tears, and in addition to it, it contains a number of other elements. Among them are various solids, protein molecules, fats and some other organic substances.

However, the main component associated with the salty taste of tears is sodium and chlorine, which together form common table salt (sodium chloride). The concentration of these ions in tears is very high, and it is they that give tastes the characteristic and salty taste of tears.

Authority Role

Tears are included in a person’s observation of a number of basic functions. They moisturize the eyes, keeping them from drying out, dust and impacts, and help flush out waste types and toxins from the body. All these functions are realized due to the unique biochemical composition of the tear.

Ionic balance in function

But why are sodium and chloride present in such high concentrations in tears? The answer lies in the processes of regulation of the ion balance in our calculation. Sodium and chlorine are the two main ions that affect the body’s water-salt balance. They are present not only in tears, but also in sweat, blood and other biological fluids.

emotionally sluggish

In addition to reflex and basal tears, there are also emotional tears. Studies have shown that their composition is somewhat different from other types of tears. In particular, they contain more stress hormones such as adrenaline. Interestingly, some of them are not worth it, that some emotional crying functions more than alive and the body is rid of excess of these hormones.

Observation of the environment on tears?

In addition to internal biochemical processes, our environment can also influence the formation of tears. Being in a highly polluted or dusty environment can lead to the detection of certain substances in tears. When dust hits or hits the eyeballs, tears first become a protective barrier against the axis of these particles.

genetic predisposition

An interesting fact is that for some people, tears can be less salty or, conversely, more salty than drugs. Genetic factors can influence the concentration of ions and other molecules in tears. This may be due to both hereditary characteristics and the body’s response to a laboratory disease or disease.

Tears as an indicator of health

Tears can serve as important information about a person’s health. Recent studies show that tear analysis can help detect a number of diseases or inflammation in the machine. This betrays the lack of a tool for expressing emotions rather than a potential biomarker using health problem solving techniques.

Comparison with animal tears

Humans are not the only creatures on the planet that have tears. However, in different species of animals, tears can have a different composition. For example, in some marine animals, tears are much saltier than in humans, which is associated with adaptation to the marine environment.

Tears are not just a liquid that comes from crying or irritating the eyes. They play a key role in protecting and moisturizing the eyes, and they can say a lot about our health and the environment. Modern science continues to study this unexpected phenomenon, and who knows what other secrets our sloppy.
