Redhe feel more pain, studies have shown. At least, a different kind of pain. To say that redhe have their own charm would be an understatement, but it has also had its downsides — particularly during the Dark Ageswhen gingers were often considered witches or heretics. Red hair is most commonly found in the northern and western parts of Europe, especially in and around the British Isles. Still, even so, red is, by a wide margin, the rarest natural hair color.
Genetic studies have shown that a protein-coupled receptor called MC1R holds the key for this mutation. The MC1R protein is responsible for hair color, which can range from black or brown to lighter colors such as blonde and red. Most redhe have a recessive version of the MC1R gene. The pigment also contributes to eye color. In addition, MC1R has also been reported to be involved in cancer independent of skin colorationdevelopmental processes, and susceptibility to infections and pain.
Contrary to a popular belief, redhe are not disappearing. A report in The Courier-Mailwhich cited a National Geographic article and unnamed geneticists, claimed redhe were slowly disappearing. The story turned viral and became extremely popular. In truth, it was more a marketing stunt than a scientific article. But back to our genetic makeup. We know that at least some probably most of the genetic differences in redhe are associated with MC1R.
Like most other cell surface receptors, MC1R is regulated by a set of complementary proteins. But, in redhe, the mutation to MC1R le to the production of a red pheomelanin, the pigment that gives the specific hair color. But it gets even more interesting. The same mechanism that causes this red-tinged pigment also stimulates some hormonesincluding those called endorphins. Today, many geneticists are confident that the MC1R gene is directly related to pain. A of studies have shown redhe feel pain differently and have different body reactions.
For instance, one study found that people with red hair are more sensitive to thermal pain, while another showed that they are less sensitive to a wide array of painful stimuli, including electrically induced pain. To make it even more intriguing, research has also shown that redhe require more anesthetic. However, this is where things get interesting. This seems to strongly indicate that redhe process pain differently than other people, probably due to MCR1.
In other words, redhe do feel more pain, but they also feel less pain — they just process pain differently. the ZME newsletter for amazing science news, features, and exclusive scoops. More than 40, subscribers can't be wrong. They react less to pressure close to the injected area, or to a pinprick. However, redhe also turned out to be more vulnerable to toothaches, and more afraid of the dentist presumably due to the stronger pain they feel.
Even more disturbingly, their genes make them more likely to suffer from several diseases, such as sclerosis. When humans migrated out of Africa, their skin color became lighter and lighter over time, as they were exposed to less sun.
The ability is very useful in places like Scotland or Ireland, where sunshine can be a scarce commodity. So, to sum up several studiesredhe:.
A widely believed myth claimed that redhe were more likely to bleed more heavily, up to the point where some surgeons refused to carry out complicated surgeries, due to a fear of excessive bleeding. That idea, however, is far less substantiated. So, we do know that the same variants that give redhe their distinctive hair hue have ificant other effects. In addition to these, some animal studies seem to indicate that redhe may react better to some drugs, and worse to others, compared with the general population. Hopefully, future studies can help us better understand these genetic differences, and help us tailor better custom treatments.
It seems that redhe do have more fun.
A recent study found that redhe appear to have more sex than people with any other hair color. It could be that they are just very rare which can make them a sought-after prizeit could be that red hair just grabs your attention and serves as an advantage, or it could be that red is an indicator of youth and fertility.
At any rate, redhe exhibit a of intriguing features. They feel more pain but are also more resistant to some types of pain, they are resistant to some conditions are more at risk from others. They draw our attention and often inspire us. Andrei's background is in geophysics, and he's been fascinated by it ever since he was.
