Bleeding Myth

1 Doctors Shouldn't Fear Red Heads

"I do feel that "redheads" are phenotypically unique."
- Dr. J in the comments

Among surgeons, red-haired patients have been feared a bit due to their "reputation" for reduced pain threshold, excessive bleeding and development of hernias. Anecdotal reports regarding increased bleeding among red heads have helped to fuel the "fire" behind what's really a myth. According to a new study published in the Christmas issue of the British Medical Journal (BMJ), there's really no need for surgeons to fear red heads! Study authors found that red heads possess no greater risk during surgery than people without red hair. That's good news for the small population of red heads around the world. Globally, only about 2 percent of the population has red hair, but in Scotland around 13 percent of people have red hair.

2 Social Smoking Can Trigger Heart Attack

While many people think the occasional cigarette smoked in social situations won't cause harm, a new surgeon general's report stresses that just one cigarette can trigger a heart attack by blocking arteries. According to the report, harm from smoking begins right away as more than 7,000 chemicals invade the body, causing cellular damage in nearly all organs. For people with silently clogged arteries, that seemingly innocent cigarette, however rare, can be deadly. MSNBC reports that cigarette smoke changes the blood's chemistry, making it more sticky, and making the body more prone to clots that may shut down narrowed arteries. The surgeon general's report devotes around 700 pages to explaining the biology behind how cigarette smoke affects the body.

Teen Brains Need Exercise

3 Girls Who Walk to School Have Better Scores

Girls who walk or bike to school do better on tests, but the same isn't true of boys, reports Reuters. For the study, researchers from the Spanish National Research Council in Madrid analyzed test scores of 1,700 urban teens and asked them how they got to school. Girls in the study performed better on verbal and math tests if they got exercise on the way to school instead of riding, and the longer the commute, the better the score. The relationship between longer commutes and better scores existed regardless of how much other exercise was experienced other than the commute to school. Researchers aren't sure why walking or biking to school wasn't associated with higher test scores for boys.
