Pediatric Myths

Myth 1: Sugar Makes Children Hyperactive

This is one of the most widespread urban legends. Many parents attribute their children's energetic behavior, especially after parties or consumption of sweets, directly to sugar.

The Scientific Reality:

Multiple scientific studies, including meta-analyses and systematic reviews, have found no direct causal relationship between sugar consumption and hyperactivity in typically developing children.

• The energy after consuming sweets at a social event may be due more to the excitement of the event or the expectation of receiving a prize, than to sugar itself.
• There is the nocebo effect or the expectation: Parents who believe that sugar causes hyperactivity often report more hyperactivity in their children after sugar consumption, even when given a placebo.
• What is true is that excessive sugar consumption is unhealthy for other reasons (risk of obesity, cavities, etc.), but not because it induces hyperactivity.

Parent Tip: Instead of blaming sugar for "hyperactivity," help them identify the child's sleep patterns, physical activity level, and emotional environment.

Myth 2: Exposure to the Cold Causes Colds

"Wrap yourself up or you'll catch a cold!" is a common phrase that reflects the belief that the cold itself causes respiratory infections.

The Scientific Reality:

Colds and flu are caused by virus, not because of the cold weather.

• The higher incidence of colds in winter is due to people spending more time indoors. poorly ventilated interiors, which facilitates the transmission of viruses from person to person.
• Respiratory viruses, such as rhinovirus and influenza virus, survive better and spread more easily in cold, dry environments.
• Cold can temporarily weaken the mucosal defenses of the upper respiratory tract, but does not cause infection if the virus is not present.

Parent Tip: Teaching good hand hygiene, avoiding contact with sick people and ventilating spaces are more effective measures to prevent colds.

Myth 3: Cracked Joints Cause Arthritis

It is common to hear that the habit of cracking your knuckles or neck will inevitably lead to developing arthritis.

The Scientific Reality:

The sound produced by cracking a joint (rubbing) is due to the release of gas bubbles (nitrogen, oxygen and carbon dioxide) within the synovial fluid.

• Numerous studies, including a famous study of a doctor who cracked the knuckles on one hand for 50 years and not the other, have found no evidence linking joint cracking to the development of arthritis.
• There may be a slight association with inflammation or swelling of the hands in very chronic cases, but not with permanent joint damage or arthritis.
• In rare cases, vigorous neck cracking can have risks if done incorrectly, but this is not related to arthritis.

Parent Tip: You can explain that it is a harmless habit, but if the child feels pain or is worried, they should consult you.

Myth 4: Vaccines Cause Autism

Perhaps the most dangerous and persistent urban legend in the pediatric setting is the belief that vaccines, particularly the MMR (measles, mumps, rubella) vaccine, cause autism.

The Scientific Reality:

This theory was based on a fraudulent 1998 study that was retracted and whose author lost his medical license. Since then, thousands of large-scale studies around the world have categorically refuted any link between vaccines and autism.

• Leading global health organizations, such as the WHO, the CDC, and the American Academy of Pediatrics, have stated that vaccines are safe and do not cause autism.
• Autism is a complex condition with genetic and neurobiological bases, and its symptoms often manifest around the age at which some vaccines are administered, which led to a false correlation.
• Declining vaccination rates due to this myth has led to disease outbreaks preventable by vaccines, such as measles.

Parent Tip: It emphasizes the safety and effectiveness of vaccines, and the serious risks that non-vaccination poses to the child and the community.

Myth 5: You Shouldn't Swim After Eating Because It Causes Congestion

It is a long-held popular belief that swimming immediately after eating can cause severe congestion or cramp that could be dangerous.

The Scientific Reality:

While it is true that digestion diverts some blood flow to the stomach, the amount is not enough to "steal" blood from the muscles to the point of causing disabling cramp or dangerous congestion in healthy people.

• "Congestion" or cramp can occur for many reasons during exercise, such as dehydration or overexertion, but there is no evidence that eating before swimming is a direct and common cause of drowning or serious problems.
• It is wise to avoid very heavy meals before any strenuous exercise to avoid stomach upset, nausea, or a feeling of heaviness, but not because of the risk of lethal "congestion."

Parent Tip: Recommends that children listen to their bodies. If you feel heavy or uncomfortable after a big meal, you can wait a bit, but there is no hard and fast rule against swimming after a light snack.

Myth 6: Fever is Bad and Should be Reduced at All Costs

Fever often causes great concern in parents, who strive to bring it down quickly at any cost.

The Scientific Reality:

Fever is not a disease, but a natural and protective response of the body to an infection or inflammation. It is a sign that the immune system is working.

• A moderate fever helps the body fight infections, since many viruses and bacteria do not thrive at high temperatures.
• The main goal of treating fever is not to normalize the temperature, but improve child comfort. If the child is active and does not show significant discomfort, a low to moderate fever may not require medication.
• The important thing is to observe the child's general condition (activity, hydration, mood) and not just the number on the thermometer.

Parent Tip: Explain to them that fever is an ally and that attention should focus on the child's general well-being, not just the number on the thermometer. It is recommended to observe warning signs and not hesitate to consult.

Myth 7: Baby Teeth Are Not Important

Some parents believe that since baby teeth are going to fall out anyway, it is not so important to care for them or treat cavities in them.

The Scientific Reality:

Baby teeth are fundamental for oral development, nutrition and speech of the child, and are also "guides" for the permanent teeth.

• They help the child chew correctly, which is vital for good nutrition and digestion.
• They are essential for the development of clear speech and to avoid pronunciation problems.
• They hold space for the permanent teeth that are growing underneath. If lost prematurely due to cavities or extractions, permanent teeth may erupt crooked or crowded.
• Cavities in baby teeth can cause pain, infections that affect the child's general health and can spread to permanent teeth.

Parent Tip: Emphasizes the importance of good oral hygiene from the first tooth and regular visits to the pediatric dentist.

Myth 8: Children Should Finish Everything on Their Plate

The belief that children should "clean their plate" to avoid wasting food or to make sure they eat enough is very common.

The Scientific Reality:

Forcing children to eat beyond their satiety can interfere with your natural ability to regulate appetite and develop a healthy relationship with food.

• Children have an innate ability to know when they are hungry and when they are full. Forcing them to eat can lead to overfeeding and weight gain in the long term.
• It can create aversions to certain foods and make mealtime a battle.
• As pediatricians, it is important to educate parents about divided responsibility in feeding: parents decide *what*, *when* and *where* is eaten; the child decides *how much*.

Parent Tip: Encourage them to offer a variety of healthy foods and respect their children's satiety cues. There is no need to force.

Myth 9: If a Child Doesn't Have a Fever, He's Not Sick

Many parents directly associate illness with the presence of fever, and if there is no fever, they assume that the child is not really sick.

The Scientific Reality:

A child may be significantly ill without fever. The absence of fever does not rule out an infection or a health problem.

• Many illnesses, especially common viral illnesses (such as a cold or gastroenteritis), can present with symptoms such as cough, nasal congestion, vomiting or diarrhea, without the body temperature rising.
• Some bacterial infections may also not present with fever, or the fever may be intermittent.
• For very young babies or children with compromised immune systems, the absence of fever may even be a sign that their body is not mounting an adequate inflammatory response.

Parent Tip: Remind them to pay attention to other symptoms, such as activity level, appetite, behavioral changes, persistent cough, or vomiting. The absence of fever is not a guarantee of good health.

Myth 10: Giving Honey to Babies is Good for Coughs

Honey is a popular home remedy for coughs in older children, but it is often thought to be safe for babies of any age.

The Scientific Reality:

honey Should NOT be administered to babies under 1 year of age due to the risk of infant botulism.

• Honey may contain spores of the bacteria Clostridium botulinum. In babies younger than 12 months, their digestive system is not yet mature enough to destroy these spores.
• Once in the intestine, the spores can grow and produce toxins that cause infant botulism, a serious disease that can cause muscle weakness, difficulty breathing and, in extreme cases, be fatal.
• For children over 1 year old, honey is a safe and effective cough relief remedy as their digestive systems are mature enough to handle the spores.

Parent Tip: It clearly emphasizes the contraindication of honey in children under 1 year of age. For coughs in babies, he recommends consulting the pediatrician and focusing on comfort measures and liquids.
