Redheads (Natural) Are More Suseptable to Pain

"News for Redheads
Tue Oct 15, 1:11 PM ET

WASHINGTON (Reuters) - Redheads may actually

have another trait that makes them stand out -- sensitivity to pain, specialists reported on Tuesday.





People with natural red hair need about 20 percent more anesthesia than people with other hair colors, they told a

meeting of anesthesiologists. The unexpected finding not only suggests that redheads are more sensitive to pain, but offers

insights into how anesthesia works in people.

"Red hair is the first visible human trait, or phenotype, that is

linked to anesthetic requirement," Dr. Edwin Liem of the University of Louisville in Kentucky said in a statement.



"In a nutshell, redheads are likely to experience more pain from a given stimulus and therefore require more

anesthesia to alleviate that pain," he added.

Liem, who reported his findings to a meeting in Orlando, Florida of the

American Society of Anesthesiologists, said the finding is important news for specialists who monitor patients during

surgery.

"The art and science of anesthesiology is choosing the right dose," he said. "There is very little

difference between the effective dose and the toxic dose of most anesthetics. Patients can awaken during surgery if they are

given insufficient anesthesia or suffer cardiac and pulmonary complications when they are given too much."

He said

scientists do not fully understand how anesthesia works, but the findings offers clues, as people with red hair have a

certain genetic variant.

"Since red hair can be traced to particular mutations (variations) in the melanocortin 1

receptor, we now have the opportunity to evaluate central nervous system pathways that may influence or mediate anesthetic

requirement," Liem said.

"Investigating the role of melanocortin system in the central nervous system is thus likely

to help us understand fundamental questions such as which systems in the brain produce unconsciousness and which modulate

pain perception."

Liem's team studied white women aged 19 to 40 who were given the inhaled anesthetic desflurane.

Their physical responses were closely monitored, especially unconscious reflex arm or leg movement in response to painful

stimulation.

More anesthesia was needed to block movement in redheads than in participants with dark or blond hair,

Liem said."


What constantly amazes me is the huge increase in knowledge about the human body that we have obtained

in only the last few years. It's stuff like this that makes me want to be around for another 50 years! Razz

anywhere.

Very interesting.

I read last week that according to the latest genetic research, all redheads have Celtic (or part Celtic!) ancestry. The gene for red hair apears only among the Celts.

Do you suppose that Celts are more highly strung? Or perhaps more imaginative?

Do you suppose there is any connection between the low pain threshhold and the likelihood of fair-skinned red heads to sunburn?

I like this theory - it explains why I am such a wuss at present, when a small medical problem is causing me significant discomfort.

Now I know it's because I'm a redhead, see.
Yes, I know I'm not a natural redhead, but close enough!!!

And yes, I'm very fair and sunburn at the drop of a hat..or any other thing. All sounds sensibnle to me.

Noddy, where did you read this bit of genetic trivia? I'm interested because I had always understood that the red-headed gene is a Nordic phenomenon and that the Irish (and other Celts) inherited it from raiding Vikings. This, I was led to believe, is the reason why there are red-headed Greeks and Turks -- a heritage from the Varangian Guard, the Norsemen who constituted the personal body guard of the rulers of the Byzantine Empire. I'll bet there are more red-headed Norwegians than Scots.

One thing I do like about Tejas, lots of redheads here, lots. Makes me feel at home. Actually lots of redheads, the natural kind in all the south eastern states too. I was the only one in my entire family and that lead to lots of teasing about who my father really was. My mom was burnett and most of the others blone. One thing weird is all of them have either pale blue eyes or hazel and I have brown. What is that all about?

Joanne, for me I have never seen or found a statement so true as what you have signed with - by Thomas Merton. Thank you for sharing this! And yes, I like your avatar and the profile message about it. What a treat - you are an original thinker!

Thank you MA but I was the only one!!!! You know what your
avatar looks exactly like I thought you would and I thought you had posted your real portrait so I copied you. But when I noticed I was the only one I got to shy. And I think a jpg of Grand Junction looks like me too.

@Merry Andrew,
I'm no authority, but I heard it was the other way around. The Nordics were blond and mated with the Celts to get the red gene in their pool.

@Phoenix32890,
Given that is well established, what about redheads after they turn grey? What about us auburns, or used to be auburns..

@ossobuco,
Just realized this is an old thread.. maybe they've verified this, or figured out about redheads gone grey.

@ossobuco,
Once a redhead, always a redhead. It's really a state of mind.
