Redheads are more efficient at producing vitamin D Redheads lack a protective dark pigment that absorbs and scatters the sun's UV rays called eumelanin. Because of this deficit, the UV rays can more easily react with the 7-D in their skin producing vitamin D very efficiently.
Thanks to higher concentrations of red hair and pale skin in cloudy European environments, redheads gained a greater ability to create their own vitamin D. When they go outside, he or she produces more vitamin D in a shorter amount of time than people with other hair colours.
According to Health Magazine, redheads can produce their own vitamin D when exposed to low levels of light. 4. You may not need as much pain medication. The gene responsible for red hair (MC1R) also releases a hormone that is similar to endorphins which limit the feeling of pain.
Lifespan. Redheads can live as long as 21 years in the wild.
Less expectedly, red hair is also associated with pain sensitivity, endometriosis, Parkinson's disease, decreased platelet function and, perhaps, defects in the immune system [2–11]. These associations seem to involve a risk factor not directly related to fairness of skin and vulnerability to UV.
Rarest kind of redhead
Having red hair and blue eyes is the rarest hair/eye color combination possible. The odds of a person having both of those recessive traits is around 0.17%. Instead, most redheads have brown, hazel or green eyes, according to Medical Daily.

Redheads lack a protective dark pigment that absorbs and scatters the sun's UV rays called eumelanin. Because of this deficit, the UV rays can more easily react with the 7-D in their skin producing vitamin D very efficiently.
One of the many facts about redheads is that their hair will never turn grey. The pigment in their hair that causes it to be red will just fade over time, causing their hair to turn blonde or white, but never grey.
While some studies suggest a potential link between certain genetic variations and alcohol metabolism, the idea that redheads universally have a higher alcohol tolerance remains inconclusive and should be approached with caution.
A 2003 study showed that people with naturally red hair can tolerate pain up to 25% better than others. The results of another study conducted at the University of Louisville have shown that redheads are more sensitive to temperature changes.
Nature's Rarest Palette: Red Hair Standing at the apex of rarity, natural red hair occurs in just 1-2% of the global population. This striking shade results from a specific genetic variant of the MC1R gene, requiring both parents to pass on the recessive trait.
Only hair length and the hair colors “brown” and “brown and red” have been identified as independent risk factors for head lice infestation. Most head lice die without ingesting more blood within 30 hours after the last feed (18).
Did you know? These red hair variants in MC1R likely first appeared in ancient humans around 30,000-80,000 years ago, at about the same time as early migrations out of Africa. Scientists used to think red hair evolved to help people produce Vitamin D in chilly places with little sunlight (think Ireland).
But here's the thing. Despite its popularity, strawberry blonde hair only occurs naturally in between 1 and 2 percent of the world's total population — which means it takes hair color and technique to make it happen for the rest of us. In fact, it's a hue that's been rare yet in demand for centuries.
Study says redheads age slower 😍💃😎According to research published in Current Biology, people with the MC1R gene, aka the gene that produces red hair, tend to look several years younger than their non-ginger counterparts.
In fact, copper and bright ginger hair have the widest range of flattering shades, working exceptionally well with soft pastels, earthy tones, warm neutrals, and pretty much every shade of green and teal. Think of baby blue, mint green, soft yellow, and sandy beige as your best allies!
Prior research has already put red-haired humans and mice into the spotlight, pointing out that they have a higher pain threshold. They also don't need as high of a dosage of pain-killing opioids, and they tend to require more anesthesia compared to people with non-red hair.
About 1–2% of people of European origin have red hair. Especially female redheads are known to suffer higher pain sensitivity and higher incidence of some disorders, including skin cancer, Parkinson's disease and endometriosis.
Red hair is seen as bold and daring, and those with red hair are often perceived as confident and assertive. Studies have shown that redheads are more likely to stand out in a crowd and be remembered by others. This can lead to a boost in confidence and self-esteem. Brunettes are often seen as reliable and trustworthy.
Her research lead all the way back to the ginger gene's origin in Africa, tracing its spread across ancient Greece, to the redheaded mummies of China, and to Renaissance Europe. Colliss Harvey's research found that redheaded individuals have higher levels of vitamin D, which is a source of strength.
The rarest eye colors are red and violet, which are primarily found in individuals with albinism. Excluding those affected by albinism, green and gray eyes are considered the most uncommon.
All hail the king. Last weekend's Irish Redhead Convention in Crosshaven, Co Cork, was a celebration of all things red and hairy, from amazing afros to bristly beards. A highlight of the festival was, of course, the crowning of a King and Queen of the redheads, an honour which went to Alan Reidy and Grainne Keena.
