Another advantage of having blue eyes
Preliminary studies suggest discoveries for people with clear irises. The color is not a simple aesthetic element
Paul Newman or Elizabeth Taylor. Who would not want their eyes? Not a week goes by without a publication echoing a survey in which the people manifest themselves: we like clear eyes. And although the dark looks give us more confidence, as the PLOS One interview published after a study at Charles University in Prague, seduction still belongs to the clearest irises.
And it's not the only advantage. We may never know if the eyes are the mirror of the soul, but what is beginning to be known about them is their ability to reveal many facts about each person's health. In fact, for years scientists have been tracking the links between their characteristics and what they show and certain diseases.
The last track comes from the hand of Inna Belfer, from the Pain Research Center of the University of Pittsburgh , in the USA. UU The doctor has presented a preliminary study at the 33rd Annual Meeting of the American Academy of Pain that reveals that Caucasian women with light eyes (blue or green) seem to tolerate pain and anguish better than those with brown eyes or hazelnut. They also suffered less anxiety after childbirth and lower rates of depression.
The work was carried out with 58 expectant mothers who gave birth at the Magee Women's Hospital of UPMC . All received an evaluation of pain, mood, sleep and coping behavior before and after delivery. The participants were divided into two groups based on their eye color: 24 in the dark range (brown or hazelnut) and 34 in the light (blue or green). The data showed that the former experienced more pain, greater anxiety and a higher rate of sleep disorders. Females with light eyes faced the process with greater happiness.
The main researcher has acknowledged that "due to the small size of the sample, we can not obtain conclusive evidence, but we do note that our study has revealed patterns that require further studies. Let's see if there is a link between eye color and clinical pain in the second phase of this trial, both in men and women, and in different models of pain other than just the birth one.
" The specialist insists: "There may be certain phenotypes that predict or indicate a person's response to pain stimuli or treatment with analgesics.Human pain correlates with multiple factors, such as gender, age and hair color.. In fact, researchers have found that red hair is associated with greater resistance to anesthetics and also an increase in anxiety. "
Dr. Gregory Terman, of the Department of Anesthesiology and Pain Medicine at the University of Washington (USA), admits that, once again, studies like this highlight that each patient is an individual and that their doses of medication They must be done in a personalized way.
"Statistically, we realize that there is much more variability before the experiences of pain according to the particular characteristics of each one, such as the color of hair, eyes, age, weight, sex ... It is a fact that also occurs in the responses to medications for blood pressure, "he adds.
Thus, hair color can also determine how affliction is faced. In fact, red-haired people, in addition to having a whiter and more sensitive skin, feel more physical pain than blondes or brunettes. This is shown by a study published in the Journal of the American Dental Association , carried out by scientists from the Institute of Anesthesiology of Kentucky, which determines that these individuals need 19% more analgesic to withstand the discomfort than those with dark hair.
The highways of pain
Concepción Pérez, head of the Pain Unit at the University Hospital of La Princesa and spokesperson for the Spanish Society of Pain , highlights: "Although studies such as clear eyes are preliminary, both this new trial and those conducted in redheads Indicating that there are probably genetic causes related to the perception of pain, deepening in this matter could be very useful in the future, because it would help us predict which people are going to need more analgesics. "
Dr. Pérez continues: "Today we know, for example, that genetics has a preponderant role to define how an individual will respond to different analgesic drugs. If it is going to have a greater or lesser effectiveness or present side effects. It is a field that currently has an important development: pharmacogenetics ".
Likewise, it is known that the brain plays a fundamental role in sensitivity to pain. For example, chronic pain alters brain circuits. Its beginning is a warning signal that protects us from the dangers. If we touched boiling oil and did not feel pain, we would end up suffering great burns. The problem happens when the pain becomes chronic. It is then when a vicious circle begins, where the roads of pain becomehighways, "he adds.
Enrique Santos Bueso, of the Neuro-ophthalmology Unit of the San Carlos Clinical University Hospital in Madrid, states: "The eyes can also speak a lot about our health." Sometimes, we find patients who come to the consultation because they believe they have an eye problem and we discovered that they are the signal of other diseases ". We dissect each case according to the strange characteristics presented by its ocular elements. Because not everyone is lucky enough to wear beautiful (and painless) clear eyes ...
DIAGNOSIS BY THE LOOK
Bloody eye. The conjunctiva is composed of many blood vessels and capillaries. These can rupture, causing blood to leak into the membrane and sclera, which is known as "subconjunctival hemorrhage." It can be caused by common causes, such as coughing, sneezing, straining or a blow.
Other common but less frequent bleeding include diabetes mellitus, high blood pressure and excess intake of certain medications, such as acetylsalicylic acid. It is strange that it is due to coagulation problems, but sometimes it happens.
Protruding eye Although prominent eyes may simply be a family trait, they also sometimes show thyroid disease.
Eyes of different color. Heterochromia of the iris is inherited. A sudden change in color may be due to a hemorrhage, a foreign body in the eye, glaucoma, inflammation, or other conditions such as Waardenburg syndrome (gene dermatosis) or neurofibromatosis.
Fallen eyelid. It may simply be a sign of aging. However, in rare cases, it is evidence of diseases.
Abnormalities of the pupil. The pupils of healthy people are, usually (though not always) symmetrical: the same size and identical reaction to light. If a pupil responds differently to exposure to light (one is larger than the other, another contracts less), check with your doctor.
Yellow eyes. Liver diseases, such as hepatitis and cirrhosis, stain the sclerotia yellow. The color is due to the accumulation of bilirubin, a compound created by the breakdown of hemoglobin, the molecule that transports oxygen within red blood cells.
