Rebecca Sager, senior vice chairman of growth for HealthyWomen, was within the prep room on the hospital on the point of ship her first little one when the nurse got here in and requested her an odd query. “Are you an actual redhead?”
“You’re going to search out out in a minute,” Sager quipped, figuring out the nurse was there to see how dilated she was. Sager is, in truth, an actual redhead. Or as she put it, the carpet matches the drapes.
Pure redheads are uncommon — lower than 2% of the inhabitants. Was the nurse so taken by Sager’s firey mane that she needed to know if it was actual? In all probability. However she additionally requested as a result of, if Sager’s hair colour was pure, it meant she may have extra pain management throughout labor.
“I’d by no means heard that earlier than,” Sager stated.
Do redheads have a better ache tolerance?
There is a rising physique of research that exhibits that folks with pink hair expertise ache in a different way in comparison with individuals of different hair colours. The jury’s nonetheless out as to why this can be, however one idea has to do with the melanocortin-1 receptor (MC1R) gene.
All individuals with pink hair are born with a mutation of the MC1R gene. That is not solely what offers them flaming locks of auburn hair, however, in line with a 2021 study, it additionally reduces the operate of the gene. And people adjustments have an effect on the stability between ache sensitivity and tolerance.
Total, analysis on redheads helps the seeming contradiction that they’ve a better tolerance for ache usually, however they’ve elevated sensitivity to sure kinds of ache.
For instance, one study discovered girls with pink hair have been extra delicate to temperature-related ache in comparison with girls with darkish hair. However one other study discovered that folks with pink hair have been much less delicate to ache by electrical shocks.
The variations do not cease on the manner redheads understand ache. In addition they reply to ache treatment in a different way. Given the vary of ache sensitivity and several types of ache, ache administration can current challenges for individuals with pink hair. Studies present redheads could require larger doses of some kinds of non-opioid ache relievers. However, the 2021 research talked about above discovered that redheads could also be extra delicate to opioids and want much less treatment to cease ache.
The sensitivity to opioids could also be much more pronounced in girls. One study discovered that girls with two mother and father who’ve learn hair — which means they’ve two variant MC1R genes — had considerably larger ache tolerance and considerably larger sensitivity to opioids.

Do redheads want extra anesthesia?
The analysis on whether or not redheads want extra anesthesia is proscribed, however should you speak to girls with pink hair, chances are you’ll hear anecdotal proof that they require extra anesthesia. Why? The speculation is again to the MC1R gene mutation, which ends up in a lowered response to anesthesia, so extra is required. One study discovered that girls with pink hair required virtually 20% extra anesthesia for sedation in comparison with girls with darkish hair.
Della Lin, M.D., an anesthesiologist and secretary of the Anesthesia Affected person Security Basis, famous that the analysis concerning redheads and extra anesthesia comes from smaller research, so it is probably not one thing your healthcare supplier (HCP) thinks about straight away.
Lin encourages individuals with pink hair — and everybody else — to deliver up any considerations about anesthesia or ache administration earlier than the process. “I’d hold that thought in the way in which again of my thoughts [that you have red hair], however I am not going to extend something by default,” Lin stated. “So it is good to know should you’ve observed that you simply’re delicate to opioids … as a result of everyone seems to be a little bit bit completely different.”
Jackie Wexler, a center faculty trainer with curly scarlet-red hair, stated she had no clue her hair colour was tied to her response to medication. However wanting again, common OTC ache medicines have not carried out a lot for her menstrual cramps or her headache assaults. “Now I’ve the worst migraine attacks and nothing helps,” she stated.

It is sensible to her that the excessive ache tolerance and excessive tolerance to sure painkillers is genetic. She stated her sister, who additionally has pink hair, wanted extra ache treatment than they’d give her when she gave delivery.
Sager is now conscious of her actual redhead standing and tries to get her HCPs on the identical web page concerning any ache treatment or anesthesia she may have. Nonetheless, some suppliers do not assume the connection between redheads and ache is true. When Sager went in for a colonoscopy, she informed her anesthesiologist that she wanted a better dose. She pointed to her head. He stated she did not. So when the nurse got here in and requested why she was nonetheless coherent and sitting up, Sager did not mince phrases. “I am a redhead. I am completely different.”
