Common Myths Debunked

I came across this article through Current, and I found it really interesting, basically because everything that it debunked, I thought was cold hard fact.

1. You loose the most heat through your head. – FALSE

bald460x276 The Facts:
– The face, chest and head are the most sensitive to temperature change of the whole  body, therefore covering them up feels like more is being done to stop heat loss.
– covering one part of the body has as much effect in heat conservation as covering any other body part.

The Origins of the Myth:
It arose from a misinterpreted 1950 experiment that found that volunteers dressed in Arctic survival suits, with their heads uncovered, lost the most heat from their head but this is because their head was the only thing exposed. This can also be found in a 1970 US army survival manual, that claimed you loose 40 – 50% of your body heat through your head.

The Facts:
Dozens of high-quality studies have investigated the link between sugar intake, and children’s behavior but no difference has been found.
– There has been no scientifically observed behavioral difference between children who consume sugar and those who don’t.

The Origins of the Myth:
The belief is primarily seen as a part of a parent’s imagination. This is so because researches have found from studies that when a child consumes what the parent believes to be a sugary beverage, when really it is sugar-free, they rate the child’s behavior as more hyperactive.

3. Snacking at night makes you fat.FALSE

The Facts:
At first glance, some research suggests there may be a link, with one study showing that obese women tended to eat later in the day than slimmer women.

-But according to the BMJ article, “The obese women were not just night eaters, they were also eating more meals, and taking in more calories makes you gain weight regardless of when calories are consumed.”

Therefore with other factors influencing heavier women that are absent in slimmer women, the claim that “snacking at night makes you fat” is not the only contribution to physical state overweight women.

4. There are many forms of hangover cures. – FALSE

The Facts:
– After an extensive review of evidence for the curative benefits of bananas, aspirin, vegemite, fructose, glucose, artichoke, prickly pear and the drugs tropisetron and tolfenamic acid, they conclude that none has been proven to cure hangovers.

– No scientific evidence … supports any cure or effective prevention for alcohol hangovers, the only way for recovering is to wait for the body to metabolize the ingested alcohol, which occurs via oxidation through the liver before alcohol leaves the body.

– However, drinking a large amount of water or a re-hydration drink prior to sleep will effectively reduce a large proportion of the symptoms but will not cure you of the hangover itself.

5. Pointsettia is poisonious. FALSE

The Facts:
The plant is not very toxic, those sensitive to latex may suffer an allergic reaction and it is therefore not advisable to bring the plants into the home of sensitive individuals.
– In a study in the American Journal of Emergency Medicine 22,793 cases of poinsettia exposures were electronically analyzed. 98.9% of the exposures were accidental with 93.9% involving children. 96.1% of the exposed patients were not treated in a health care facility and 92.4% did not require any type of therapy.
-If eaten, poinsettias may sometimes cause diarrhea and vomiting in animals and humans.
-If the sap of the Poinsettia accidentally gets into a human’s eye, it can cause temporary blindness.

The Origin of the Myth:
The origin of this could be found in the fact that most plants of the spurge genus are indeed toxic and also because the name of the plant seems to refer to the word poison.

– This misconception was spread by a 1919 urban legend of a two-year-old child dying after consuming a poinsettia leaf.
