Myth: Shaved hair grows back faster, coarser and darker Fact: A 1928 clinical trial compared hair growth in shaved patches to growth in non-shaved patches. The hair which replaced the shaved hair was no darker or thicker, and did not grow in faster. More recent studies have confirmed that one. Here's the deal: When hair first comes in after being shaved, it grows with a blunt edge on top, Carroll and Vreeman explain. Over time, the blunt edge gets worn so it may seem thicker than it actually is. Hair that's just emerging can be darker too, because it hasn't been bleached by the sun. Myth: You should drink at least eight glasses of water a day Fact: "There is no medical evidence to suggest that you need that much water," said Dr. Rachel Vreeman, a pediatrics research fellow at the university and co-author of the journal article. Vreeman thinks this myth can be traced back to a 1945 recommendation from the Nutrition Council that a person consume the equivalent of eight glasses (64 ounces) of fluid a day. Over the years, "fluid" turned to water. But fruits and vegetables, plus coffee and other liquids, count. Myth: Fingernails and hair grow after death Fact: Most physicians who queried on this one initially thought it was true. Upon further reflection, they realized it's impossible. Here's what happens: "As the body’s skin is drying out, soft tissue, especially skin, is retracting," Vreeman said. "The nails appear much more prominent as the skin dries out. The same is true, but less obvious, with hair. As the skin is shrinking back, the hair looks more prominent or sticks up a bit." Myth: We use only 10 percent of our brains Fact: Physicians and comedians alike, including Jerry Seinfeld, love to cite this one. It's sometimes erroneously credited to Albert Einstein. But MRI scans, PET scans and other imaging studies show no dormant areas of the brain, and even viewing individual neurons or cells reveals no inactive areas, the new paper points out. Metabolic studies of how brain cells process chemicals show no nonfunctioning areas. The myth probably originated with self-improvement hucksters in the early 1900s who wanted to convince people that they had yet not reached their full potential, Carroll figures. It also doesn't jibe with the fact that our other organs run at full tilt. Myth: Reading in dim light ruins your eyesight Fact: The researchers found no evidence that reading in dim light causes permanent eye damage. It can cause eye strain and temporarily decreased acuity, which subsides after rest. Myth: Eating turkey makes you drowsy Fact: Even Carroll and Vreeman believed this one until they researched it. The thing is, a chemical in turkey called tryptophan is known to cause drowsiness. But turkey doesn't contain any more of it than does chicken or beef. This myth is fueled by the fact that turkey is often eaten with a colossal holiday meal, often accompanied by alcohol — both things that will make you sleepy. Myth: Cellphones are dangerous in hospitals Fact: There are no known cases of death related to this one. Cases of less-serious interference with hospital devices seem to be largely anecdotal, the researchers found. In one real study, cellphones were found to interfere with 4 percent of devices, but only when the phone was within 3 feet of the device. A more recent study, this year, found no interference in 300 tests in 75 treatment rooms. To the contrary, when doctors use cellphones, the improved communication means they make fewer mistakes. "Whenever we talk about this work, doctors at first express disbelief that these things are not true," said Vreeman said. "But after we carefully lay out medical evidence, they are very willing to accept that these beliefs are actually false."

deols: The 10% brain use is the most ridiculous. Each part of the brain has its functions and none is dormant, for real. We actually only use 5 - 10 % of our brains capacity.....if we used all, the result will be disastrous,..pple will die young... The reason why the brain restrains some info...overloading will cause overactivity......... Every thing the human brain has set eyes on since we were born is registered in our brain......every single detail But we can't remember all, can we? 9 Likes |
