It turns out the genes that produce redheads also lead them to experience pain differently than the rest of us. Redheads are harder to sedate, but they have a different tolerance for pain, says UCI Health pain management specialist Dr. Shalini Shah.
Nobody likes going to the dentist, but redheads may have good reason. A growing body of research shows that people with red hair need larger doses of anesthesia and often are resistant to local pain blockers like Novocaine. As a result, redheads tend to be particularly nervous about dental procedures and are twice as likely to avoid going to the dentist as people with other hair colors, according to new research published in The Journal of the American Dental Association.
Redheads can most easily be spotted in Scotland, England and Ireland. Red hairas well as fair skin and freckles, is associated with genetic variations of the melanocortin-1 receptor MC1R. Melanocortin receptors there are 5 bind melanocortin peptides, a group of peptide hormones that are produced in the pituitary gland and that are all derived from the same precursor, proopiomelanocortin POMC.
Or that she must be insensitive when she doesn't seem to mind ferociously hot curry sauce that sets your mouth on fire? An increasing number of studies show that redheads are differently constituted in terms of pain perception and body reactions. Research reveals that redheads:.
CNN -- Despite two injections of anesthetic, Amy Anderson felt like her dentist was jamming rods into her tooth during a root canal. She writhed in pain as her infected tooth was hollowed with a drill, its nerve amputated, and then sealed. Studies say redheads avoid dental care after having painful experiences and may require more anesthetics.
Redheads have genes to thank for their tresses. Research shows red hair usually results from a mutation in a gene called MC1Rwhich codes for the melanocortin-1 receptor. The pigment found in redhair that makes it red is called pheomelanin.
Redheads feel more pain, studies have shown. At least, a different kind of pain. To say that redheads 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.
British Broadcasting Corporation Home. A new study has found that redheads are more than twice as likely to avoid a visit to the dentist - possibly because they are more sensitive to pain. But does hair colour really mean more discomfort in the dentist chair?
It turns out that there are a number of special genetic qualities that give those lucky redheads a surplus of evolutionary advantages. A study at the University of Louisville revealed that MC1R can amplify the activity of the genes which detect and respond to temperature changes, meaning that redheads are likely to be shivering more than most this winter. The rare MC1R gene mutation also means that flame-haired people need less vitamin D than the rest of us. In fact, research has found that an evolutionary adaptation means that they make it themselves and in a very efficient manner, reports The New York Post.
