What is it about Rachel that makes her different from Phoebe? Pain is the single most common symptom reported when seeking medical attention. Under normal circumstances, pain signals injury, and the natural response is to protect ourselves until we have recovered and the pain subsides.
Redheaded Women Respond Better To Painkilling Drug -- ScienceDaily
I read the paper and thought it would be nice to write something short about it here, both for the change of tone and to give my own perspective on it. This results in the person having red hair, light skin and an increased sensitivity to UV radiation. The study, published last year in the Scandinavian Journal of Pain , looked at the sensitity of redhead vs. As the study acknowledges, the idea that redheads have a different pain response is hardly new.
Why Surgeons Dread Redheads
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. Researchers believe redheads are more sensitive to pain because of a mutation in a gene that affects hair color. In people with brown, black and blond hair, the gene, for the melanocortin-1 receptor, produces melanin.
It's bad enough that redheads -- or gingers , as our British friends call them -- may one day be extinct. Now we find out that people with red hair need more anesthesia than other people, too. A study conducted by researchers at the University of Louisville in Kentucky , proved what anesthesiologists -- doctors who oversee the administration of anesthesia -- have believed for some time, that redheads are more difficult to knock out.
