You wouldn’t know it to look at me today, but I used to have red hair. All my life, with but a few exceptions, when I suffered from pain, I simply bucked it up, as my mother would say, and lived with it. Headaches, sciatic pain, surgery pain, you name it, I just lived with it. I often wondered how and why I had such a high threshold of pain.
Recently, I was talking with a nurse in the doctor’s office about pain, and I commented that I had been reading about pain and redheads. She confirmed it was true that redheads can bear more pain.
What is it about redheads, often called gingers, that provides us with the ability to suffer higher levels of pain?
“Research has shown that people with red hair perceive pain differently than others.” Notice they use the word perceive rather than feel.
Perception involves the brain’s interpretation of the signals the body sends to it indicating it has suffered an injury or is experiencing discomfort. Perception is the telegram the brain receives that says, “I fell down. I think I’ve broken my leg.”
Feeling, however, is the actual sensation (the pain) the body is experiencing. Pain behaviors—rubbing, guarding, sighing, grimacing, crying—can lead a person to perceive they are experiencing more pain than someone who does not engage in these behaviors and, therefore, feels less pain.
So, what do gingers have that others do not? It’s in the genes. We have a variant of the melanocortin-1 receptor (MC1R) gene which controls the production of melanin. Melanin is also the primary pigment that determines skin color. The cells that make melanin produce two forms—eumelanin and pheomelanin. Redheads mainly produce pheomelanin.
Anecdotal evidence has also shown that redheads might require additional anesthesia during medical procedures. I know that’s true first hand. I woke up during a couple of procedures, but went quickly back under once the anesthesiologist administered additional medication.

Speaking of hair, have you ever wondered why the hair on your head and chin grow continually, while the hair on the body seems to grow to a certain length and then stops?
The life cycle of the hair on our heads consists of three phases: anagen, catagen, and telogen. The anagen phase can take up to seven years. The catagen phase is a transitional phase. Hair growth begins to slow down and finally stops. This takes two to three months. The last phase, telogen, is a resting phase. Hair growth stops, and hair begins to fall out and new hair takes its place. This takes about three months.
Body hair goes through the same three phases however, it is the duration of the anagen phase that makes the difference. Approximately every four to six months the hair stops growing, falls out and new hair takes its place. A much shorter growth period than the three to seven years for head hair. Variations in phase duration and the speed at which hair grows can vary with gender and race. For instance, a woman’s head hair grows faster than a man.

Did You Know?
The record for the longest hair in the world goes to a Vietnamese man named Tran Van Hay. Because of health issues, he was unable to cut his hair for 50 years, so it grew to be 22 feet and weighed just over 22 pounds. He would wear it in a giant dreadlock, wrapping it around his head multiple times. Source: biographs.org/tran-van-hay
