Rebecca Sager, senior vice chairman of growth for HealthyWomen, was within the prep room on the hospital on the brink of ship her first baby 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, realizing the nurse was there to see how dilated she was. Sager is, in actual fact, 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 coloration was pure, it meant she may have extra ache administration throughout labor.
“I’d by no means heard that earlier than,” Sager mentioned.
Do redheads have the next ache tolerance?
There is a rising physique of analysis that reveals that individuals with pink hair expertise ache otherwise in comparison with individuals of different hair colours. The jury’s nonetheless out as to why this can be, however one concept 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 provides them flaming locks of auburn hair, however, in keeping with a 2021 examine, it additionally reduces the operate of the gene. And people modifications have an effect on the steadiness between ache sensitivity and tolerance.
General, analysis on redheads helps the seeming contradiction that they’ve the next tolerance for ache usually, however they’ve elevated sensitivity to sure sorts of ache.
For instance, one examine discovered ladies with pink hair have been extra delicate to temperature-related ache in comparison with ladies with darkish hair. However one other examine discovered that individuals with pink hair have been much less delicate to ache by electrical shocks.
The variations do not cease on the method redheads understand ache. In addition they reply to ache medicine otherwise. Given the vary of ache sensitivity and several types of ache, ache administration can current challenges for individuals with pink hair. Research present redheads could require increased doses of some sorts of non-opioid ache relievers. However, the 2021 examine talked about above discovered that redheads could also be extra delicate to opioids and wish much less medicine to cease ache.
The sensitivity to opioids could also be much more pronounced in ladies. One examine discovered that ladies with two dad and mom who’ve learn hair — which means they’ve two variant MC1R genes — had considerably increased ache tolerance and considerably increased sensitivity to opioids.

Do redheads want extra anesthesia?
The analysis on whether or not redheads want extra anesthesia is proscribed, however for those who discuss to ladies with pink hair, you could hear anecdotal proof that they require extra anesthesia. Why? The idea is again to the MC1R gene mutation, which results in a diminished response to anesthesia, so extra is required. One examine discovered that ladies with pink hair required virtually 20% extra anesthesia for sedation in comparison with ladies with darkish hair.
Della Lin, M.D., an anesthesiologist and secretary of the Anesthesia Affected person Security Basis, famous that the analysis relating to redheads and extra anesthesia comes from smaller research, so it is probably not one thing your healthcare supplier (HCP) thinks about immediately.
Lin encourages individuals with pink hair — and everybody else — to deliver up any issues 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 mentioned. “So it is good to know for those who’ve seen that you just’re delicate to opioids … as a result of everyone seems to be just a little bit completely different.”
Jackie Wexler, a center college trainer with curly scarlet-red hair, mentioned she had no clue her hair coloration was tied to her response to medication. However trying again, common OTC ache medicines have not executed a lot for her menstrual cramps or her headache assaults. “Now I’ve the worst migraine assaults and nothing helps,” she mentioned.

It is smart to her that the excessive ache tolerance and excessive tolerance to sure painkillers is genetic. She mentioned her sister, who additionally has pink hair, wanted extra ache medicine than they might give her when she gave delivery.
Sager is now aware of her actual redhead standing and tries to get her HCPs on the identical web page relating to any ache medicine 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 the next dose. She pointed to her head. He mentioned 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.”
