“Drink the juice because the vitamins are gone, “dress up warm because you’re sweating and you’re going to catch cold”, “stop watching TV so close you’re going to go blind”, generations of children have grown up listening to the same phrases from their parents. They sure sound familiar to you.
And in many cases the things your parents told you Are true. If you don’t stand up straight you may not end up like Quasimodo, but there is a risk of kyphosis or what is the same, an arched back due to poor posture.
“Lower the volume or you’ll go deaf”, maybe it was a bit exaggerated, but continued exposure to loud sounds can cause hearing loss, especially if done with headphones. And yes, it is advisable to bundle up after exercise, to avoid very strong temperature shocks.
However, other phrases that you have been told since you were a child have no scientific basis whatsoever. Here 11 myths that your mother has always told you are lies.
“Drink the juice fast, the vitamins are going to run out”
It is one of the great myths that your mother (or your father) told you. Perhaps to get rid of the tedious task of walking behind you so you can finish drinking it. The reality, however, is that, as expected, your juice will not lose vitamins if you take it long.
The clear answer is offered by a report in Spanish Journal of Human Nutrition and Dietetics. In it, the authors explain that only under extreme conditions, such as heating it to 120ºC, does the vitamin intake decrease considerably. On the contrary, “vitamin C is perfectly preserved in the juice for up to 12 hours”, they add.
However, when it comes to whole fruits or vegetables, some handling processes can affect the nutrients, reducing the contribution. Aspects such as long cooking times, prolonged storage in the refrigerator or contact with water are some of them, the document emphasizes.
“If you swallow gum, it sticks to your stomach and you can die”
Perhaps when you were a child one of the most dangerous things you seemed to be doing was chewing gum, in front of the endless bad things that could happen to you if you swallowed it.
However, even if urban legends, or rather your mother, threatened drowning, sticking to the walls of your stomach for eternity, or death in the most extreme threat, actually swallow the gum it is something innocuous unless you do it in an exaggerated way.
The material it is made from may not be intended to be ingested, but once inside your body it will pass through your digestive system until it is expelled almost intact. Only very rarely have large amounts of gum coupled with constipation blocked the intestines in children.
“If you took more vitamin C you wouldn’t catch a cold”
The belief that vitamin C can help stave off a cold It is a widespread idea, which however does not correspond to reality.
The myth arose in the 1970s, when Nobel laureate Dr. Linus Pauling claimed that high doses of this antioxidant “prevent the common cold. To do this, he based himself on a study of children in the Swiss Alps that he later extended to the entire population. And since then the idea has circulated creating the legend, as he explained in Business Insider the family doctor Mike Seville.
However, as stated in a review of studies for the Cochrane Library, published in 2013, there is not enough evidence to support this. Now, some trials have pointed out in ways that vitamin C could help make the cold less.
“You can’t take a shower until you finish digesting,” which usually meant waiting 2-3 hours
You spent childhood summers waiting for them to pass 2 hours after eating to be able to get into the water. The directions were clear. no baths until digestion. The opposite was to expose yourself to interrupting this process that, among other symptoms, could leave you unconscious in the water.
However, it is another urban legend with little scientific basis, since these risks, which also include vomiting, nausea or dizziness, have more to do with the change in temperature than with the digestive process.
During the digestion phase, much of the blood goes to the stomach for the digestive process, blends into newthral the president of the Spanish Society of Internal Medicine, Ricardo Gómez Huelgas. “If the body is subjected to added stress such as a change in temperature, there may be this reaction of lowering blood pressure or other symptoms.”
That is the risk is really in throwing yourself into the cold water after eating, especially if it is a copious meal or alcohol has been ingested. In fact, 2 hours is how long it takes for the stomach to empty, but digestion continues.
So they should rather have asked you to you get into the water little by little, to avoid risks.
“You’re going to go blind from watching TV so close”
As indicated by the Vistaláser ophthalmological clinic, children are able to see clearly at a shorter distance, than adults. “That’s why they have no problem getting closer to the television and seeing well“. However, this habit always seems to be accompanied by the same warning from adults: “if you continue like this you will end up blind.”
Today none of this will happen. But there was a time when this threat made some sense. Perhaps giving rise to the subsequent myth.
In 1967, General Electric reported that many of its color televisions emitted excessive x-rays due to a “factory error”. Health agencies estimated this to be between 10 and 100,000 times higher than the rate considered acceptable. As a result, they recommended not seeing her for more than an hour at close range. to avoid eye injuries.
The company recalled faulty models and today watching TV is a safe habit no matter how far away. “There is no evidence that radiation from televisions has resulted in human injury,” the FDA emphasizes.
Although concentrating on a screen for hours does not cause blindness, can cause eyestrain. What is not permanent damage and can be avoided among other things with correct lighting.
“If you don’t cure that cold you’re going to end up with the flu”
Colds and the flu are different conditions, caused by different viruses. The symptoms, although similar, also differ, since the second is usually more severe.
In addition a cold is a pathology that will never be “badly cured”they emphasize from Cigna Salud. “If a time passes and the symptoms persist, it is that there really is another disease involved, such as pneumonia, bronchitis or the flu,” they affirm.
As a general rule, most colds last 3-7 days, while the flu lasts longer. With symptoms such as fatigue that can last even weeks.
“Don’t go with wet hair, you’re going to get sick”
Going out with wet hair will not give you a cold, since this is only generated by viruses. Now, the phrase was not entirely wrong, since it can create the perfect scenario for them to enter your body.
Wet hair, or humidity in general, will lower body temperature. What makes defenses less effective from areas such as the nostrils or the throat, the main routes of entry of the virus, as pointed out by a study in PNAS.
Conducted by researchers at Yale University, mice were infected with the common cold virus to test their immune system response at different temperatures. The cells in the nose of the mice were less effective in the cold.
“The drink of time, otherwise you will get angina”
Nothing to go overboard with ice cream or put a lot of ice in Coca Cola, because according to your mother all that would end in sore throat
However, this is not the case, since the Tonsillitis is an infectious disease caused by viruses or bacteria. Which produce in your body inflammation of the tonsils, sore throat and fever.
It is transmitted by “contagion by coughing, sneezing or simply speaking,” explains Dr. Francisco Javier Cervera Paz, a specialist in Otorhinolaryngology at the University Clinic of Navarra. So it has nothing to do with eating frozen foods or drinks.
“I’m going to shave your hair so it grows stronger”
Perhaps when you asked your mother about that shaved head she gave you as a child, she would answer that it was so that your hair would grow stronger or thicker. However, it is one more myth of your childhood.
As the experts point out, shaving your hair, whatever the area, will not influence its growth. It happens that it can be perceived that way because the underside of the hair is thicker and it is the first that emerges after being shaved, giving the appearance that the hair is stronger. However, as it grows, it naturally erodes into a finer shape.
“If you get cross-eyed you can stay like that”
If as a child you tried if you could make you cross-eyed it is more than possible that some adult encouraged you to stop doing it because of the risk of “ending up staying like this”.
But squint, medical term to refer to crossed eyes, is not something that happens just like that. The muscles that surround the eye (6 in total) work together, and when this does not happen, this difference in alignment can occur.
Conditions such as diabetes, thyroid disease, brain tumors or a stroke can cause it as an adult, according to the American Academy of Ophthalmology. While being born prematurely, with cerebral palsy, hydrocephalus or Down syndrome can cause it from infancy.
“Drink milk or you won’t grow up”
The Calcium is essential during the growth stage as it ensures strong bones in the future. Severe deficiency, along with vitamin D, can generate in children and babies rickets. A condition that softens the bones causing bow legs, growth retardation, and muscle weakness.
The milk and dairy products in general are the best sources of this nutrient. But they are not the only ones. So your mother could also have used, in addition to yogurts and cheeses, dried figs, broccoli, almonds, spinach or certain fish that can also provide a large amount of calcium.
