Redheads feel hot and cold temperatures more severely than anyone else. In 2005, the University of Louisville discovered this hidden gift and hypothesised that the redhead gene, MC1R may cause the human temperature-detecting gene to become over-activated, making redheads more sensitive to thermal extremes.
Humans and mice with red hair have a different tolerance for pain because their skin's pigment-producing cells lack the function of a certain receptor. Lack of this receptor function causes changes that tip the balance between pain sensitivity and pain tolerance.
They are typified as impulsive, quick-tempered, libidinous, and wild. The personalities of people with red hair are often believed to be imitative of their red hair, and they are seen as fiery, hot-tempered, hot-blooded, passionate, and angry.
Eumelanin ranges from brown to black in colour. Pheomelanin ranges from red to pink. Redheads have much more pheomelanin than eumelanin in their bodies. That's why their skin tone is often so light, and why their hair is often reddish.
A study headed by Dr. Edwin Liem at the University of Louisville in Kentucky found that redheads are more sensitive to hot and cold, and are hurt by the cold at temperatures nearly 11 degrees Fahrenheit warmer than others.
Redheads (men and women) differ chemically from the rest of us in that they can't make melanin (the brown pigment in freckles and tans). Instead, they make pheomelanin, which is reddish. Their sweat doesn't differ in composition from anyone else's, so there is no reason for them to smell different.
They easily detect changes in hot and cold temperatures. They may be less sensitive to electric shock, needle pricks and stinging pain on the skin.
Some evidence suggests redheaded adults often appear older than their actual age. For example, one study published in 2016 in Current Biology found that adults who carry two copies of the MC1R gene variant are more likely to look two years older than other people their age.
Research indicates that redheads have higher thresholds for pain and need less vitamin D than the rest of us thanks to the MC1R gene mutation, which gives their hair its hue.
Less than 2 percent of the world's population has red hair, making it the rarest hair color in the world. It's the result of the mutated MC1R gene. If both parents carry that gene, their child has a 25% chance of getting lovely, red locks, even if the parents don't have red hair themselves.
Other Sacharov redlines: "The connection between red hair and a fiery temperament may be more than just an old wives' tale. An Israeli psychiatrist reported that redheaded children are three to four times more likely than others to develop hyperactivity.
The conclusions come from a survey of 10,878 white Americans asked about their natural hair colour (Hispanics and African Americans were excluded to eliminate bias). The results showed the average IQ of blonde-haired women was 103.2, 102.7 for brown hair, 101.2 for red hair and 100.5 for black hair.
People with red hair also respond more effectively to opioid pain medications, requiring lower doses. People with red hair have a variant of the melanocortin-1 receptor (MC1R) gene.
FALSE! People tend to think that because we have red hair, we must have a red hot temper. While this may be true for some redheads, we're just like everyone else. Our hair color doesn't determine our attitude, but be careful because sometimes ginger will snap.
There's more research on the variations in human hair color than you might expect, and the science makes it clear that crimson locks are not becoming increasingly rare, nor will they disappear any time soon. It's a trait that dates to prehistory.
Fun facts about red hair strands
Redheads are less likely to go grey. The pigment in red hair typically fades over time from red to blonde and white, but not grey. Redheads produce more Vitamin D in a shorter amount of time than people with other hair colors.
Lifespan: up to 20 years in captivity, 5-10 years in the wild. Special Adaptations: Males have an elaborate courtship dance where they throw back their heads, almost touching their tail!
Blue- Royal blue or any deep blue makes red hair pop. Blue teal and turquoise hues, as well the ever popular blue denim, are great choices. Even navy works, especially for brighter red hair colors. Navy and ivory is a winning combo for dress and casual clothes.
Sex Researcher Professor Dr Werner Habermehl said: “The sex lives of women with red hair were clearly more active than those with other hair colour, with more partners and having sex more often than the average. The research shows that the fiery redhead certainly lives up to her reputation.”
Researchers think that the ginger gene, known as MC1R, may cause the temperature-detecting gene to become over-activated, making redheads more sensitive to the cold.
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.
First up, studies have found that people with ginger hair are better in bed. This is because of a specific gene connected to redheads – the MC1R gene. This gene makes the individual more sensitive to touch than people with other hair colours.
The skin of a redhead is thinner compared to others and is derived from the ectoderm. Teeth enamel is also derived from the ectoderm and thus is thinner than usual. Since the enamel coating is thin, the inner layer of tooth-dentin is more visible and offers a yellowish appearance.
And, while redheads are often stereotyped as stubborn, this isn't necessarily a bad thing. As a matter of fact, that resoluteness is linked to a particular quality of your tresses; red hair doesn't go grey easily, and the strands of hair hang onto the colour for a long time, even if it becomes slightly faded.
