Top 5 Medical Fallacies Doctors Believe
The modern world is flooded with myths and fallacies though the current level of science and medicine is much more higher than few years ago. Generally all these myths are harmless. But if the doctors themselves believe the myths concerning the functioning of a human body we have a reason to take them seriously. Some specialists aim to prove the inconsistency of the most wide spread fallacies but they generally don’t succeed. The people tend to suppose the words of their local Gps to be the absolute truth.
The latest issue of “British Medical Journal” is completely devoted to analyzing the most frequent medical misbeliefs from the fact, that each person should drink at least eight glasses of water per day to the postulate saying that reading in the dark will damage the eyesight. The authors of the magazine are worried about the present-day situation when the doctors believe blindly the obvious nonsense and convince their patients in their competence. It is a common thing that mass media gives references to these fallacies considering them to be the scientifically proven facts. As a result the readers of newspapers and viewers of numerous TV channels accept all this nonsense in all good faith. Now it’s time to make an appointment with your local GP and find out if he believes that …
- We use only 10 % of our brain resources. The authorship of this statement is erroneously foisted to Albert Einstein. The modern medical equipment, such as magnetic resonance tomography or echoencephalograph haven’t shown that our brain has inactive cells and sleeping neurons. This myth appeared in the early 90s.
The perfectionists who spread this fallacy try to prove that a human being still hasn’t reached the peak of evolution. To prove the opposite suggest them to imagine the situation if our kidneys of liver would use only a half of their resources.
- One should drink no less than eight glasses of water a day. The research shows the absence of this necessity. Probably this myth appeared in 1945 when the National Association of American Nutritionists published the recommendation to consume eight glasses of fluid per day. Gradually the notion “fluid” transformed into “water” and the fluids contained by fruit and vegetables ceased being taken into consideration.
- Nails and hair continue growing after the death of their owner. In fact the skin of a dead human dries very quickly as pebble leather does. That’s why the nails seem protruding forward. The body tissues lose their shape and volume while the hair and nails contain less fluids to release. That’s why the hair seem to become longer in comparison with the wizened body.
- The reading in the dark may ruin you eyesight. The scientists haven’t found any facts proving this statement. The lack of light causes the temporal straining of the tiny eye muscles. The healthy eye completely restores its functions after a 20-minute rest and isn’t somehow affected by the intensive strain.
- The hair become harder and darker after shaving. It is a mere effect of the horizontal cutoff of the shaven hair.
