What is the link between eye color and pain tolerance?
Interestingly, a person’s eye color can indicate their health status. The colored part of the eye, known as the iris, varies among individuals and races. Researchers have found that eye color is strangely linked to pain tolerance, mental speed, personality, and overall health. In this section ofSelMagzWe will explain the relationship between eye color and health-related issues.
The Connection Between Eye Color and Health
The eye color you inherit from your parents can be related to your health status and susceptibility to various diseases.
The Connection Between Eye Color and Skin Diseases
People with light skin and eye color have less melanin in their skin, making them more sensitive to sunlight, which increases their risk ofskin cancer.Therefore, it is advisable for them to always use sunscreen to protect their skin.
The Connection Between Eye Color andHearing Problems
People with light eyes who work in noisy environments are more likely to experience hearing issues compared to those withdark brown eyes.Studies have shown that melanin pigment protects brain nerves from noise damage.
Light Eye Color andDiabetes
Eye color is linked to diabetes. People with blue eyes are more likely to develop type 1 diabetes than others, while 9% of those affected have different eye colors.
Pain Tolerance and Its Relation to Eye Color
Studies show that people with lighter eyes display greater pain resistance. Additionally, pregnant women with light eyes experience less pain during childbirth andafter pregnancyare less likely to experiencedepressionand show fewer negative thoughts.
12 to 13 single changes in genes determine a person’s eye color. The genes involved in eye color carry out various functions. For example, the gene NCX-4, associated with darker eye colors, controls several proteins, one of which is related to pain.
The Connection Between Eye Color and Blindness
People with light eye colors are more likely to develop age-related macular degeneration (AMD) because their eyes are more sensitive to light. In this condition, light-sensitive cells at the back of the eye begin to deteriorate, leading to decreased vision.
The Connection Between Eye Color and Hereditary Liver Disease
Individuals with light skin and eye color have less melanin, while those with dark skin and eyes have more. The hereditary liver disease known as Dubin-Johnson syndrome is associated with brown pigments in liver cells and is related to melanin levels.
The Connection Between Eye Color and Intelligence
Melanin determines the darkness of eye color and acts as an insulator for electrical connections between brain cells. Increased melanin in the brain leads to improved efficiency and sensitivity of brain cells, enhancing brain function.
Individuals with dark eyes perform better and faster on intelligence tests because melanin acts as an insulator for connections between brain cells, allowing the brain to react quicker. The more melanin present in the body, the darker the eyes will be.
However, individuals with blue eyes tend to think more cautiously and strategically. Blue-eyed individuals perform better in activities like golf and studying for final exams, which require planning and structuring of time.
Personality TraitsBased on Eye Color
Dark Brown:
Almost black eyes, which are in fact dark brown, are among the rarest eye colors. These individuals often have a mysterious personality but are considered desirable.
Brown:
People with brown eyes are loyal, trustworthy, respectful, and noble, but they are definitely not submissive. They sleep two hours less than those with light eyes and generally have a shorter sleep cycle.
Blue:
Inner and physical strength are two characteristics of blue-eyed individuals; however, many people may not notice this about you. In fact, most people do not see your true self and may judge you negatively before getting to know you.
They may perceive you as shy, unreliable, or weaker than you truly are. Blue-eyed individuals tend to hide their emotions and are more alert to new things.
Blue-Eyed Individuals’ Preference for Alcohol
People with blue eyes show a greater tendency to consume alcohol and drink more than those with dark-colored eyes.
Final Thoughts About Eye Color
Originally, all humans had brown eyes. Six to ten thousand years ago, a genetic mutation in an individual near the Black Sea led to the emergence of blue eye color. Another theory attributes the spread of eye color changes to cold weather and dark skies.
Permanent eye color may not be determined until 9 months or even 18 months of age, as time is required for melanin production.
