Fat, pain tolerance is reflected in eye color

Not only is the 'window of soul', eyes and especially eye color can reveal health status and some of your abilities.

The association between eye color and health has attracted scientists for many years, leading to a series of elaborate studies, showing that eye color affects how much pain the owner feels , danger muscle with diabetes, brain processing speed and his / her weight.

The latest study by experts from the University of Pittsburgh (USA) found that Caucasian women own a bright eye color (blue or green) that seems to suffer better pain and exhaustion than their peers. has brown or golden brown eyes.

In addition, women with lighter eyes are also less likely to become anxious after birth, have a lower rate of depression and have fewer negative thoughts.

Although more research is needed to find the exact cause for this difference, experts say, it is more likely because of genetic relevance .

Until recently, it was thought that there was only one type of blue-eyed gene and another for darker eye color. However, according to Dr. Jari Louhelainen, senior lecturer in molecular biology at Liverpool John Moores University (UK), this statement is completely wrong, because the researchers are well known, eye color based on 12 - 13 separate variants in human genes.

As for why eye color can determine our health, Dr. Louhelainen explains that it is because the genes that regulate eye color can take on many roles at the same time . For example, the gene NCX-4, which is associated with darker eye color, controls more proteins involved in pain.

Other genes associated with melanin, the pigment that causes darker eye color, have also been found to be associated with pain. For example, Dubin-Johnson syndrome, a genetic liver disease that causes liver cells to brown, is associated with melanin accumulation. Symptoms of illness include pain and fatigue.

Melanin can also make brown-eyed people more vulnerable to alcohol and more likely to get drunk. Meanwhile, bright-eyed people have better alcohol content and often drink more alcohol.

Melanin not only determines the darkness of the eye color, but also the insulator for electronic connections between brain cells. The more melamine we own, the faster, more responsive and efficient our brains work, according to the research report published in Personality and Individual Differences. This advantage in brain processing speed can help explain why brown-eyed people often have faster reaction times as well as better tennis or badminton players than blue-eyed people.

The 1991 study of psychologist Dr. Anthony Fallone of the University of Edinburgh (UK) also showed that dark-eyed students achieved significantly better results in many time-limited intellectual tests. time, when the speed of thinking brings a certain advantage.

Meanwhile, the slower response of blue-eyed people may imply, they think more strategically and deliberately. According to tests at the University of Louisville (USA), blue-eyed students prove more successful in activities that require planning and time allocation, such as playing golf, running a marathon and learning to Examination.

Studies also found evidence that, compared to people with darker eyes, those with blue eye color were more likely to develop type 1 diabetes and hearing problems. Especially, in terms of personality, blue-eyed people are also more afraid, timid and anxious than brown-eyed people.
