As a doctor, I have seen how many health myths are repeated every Halloween. Some are so popular that even well-informed patients believe them. The problem is not just the scare, but the real consequences they can have for health. In this article, we will debunk the most common myths and offer reliable recommendations from a medical perspective.

Myth 1: sugar makes children hyperactive

This myth leads many parents to drastically restrict candy consumption for fear that children will “go crazy.” However, clinical studies have not shown a direct relationship between sugar and hyperactivity.

What really happens: Halloween involves emotions, adrenaline, costumes, night outings… All of this excites children, not just sugar.

Professional advice: Control the amount for dental and nutritional health reasons, but without creating anxiety or guilt.

Myth 2: any costume makeup is harmless

Many costume makeup products contain parabens, fragrances, or dyes that can cause dermatitis, allergic eye reactions, or even mild poisoning if accidentally ingested.

What I have seen in practice: Children with rashes, irritated eyes, and mild cases of poisoning after contact with certain makeup products.

Medical recommendation: Use hypoallergenic products, preferably dermatologically tested. Do a patch test on a small area before applying to the entire face.

Myth 3: costumes carry no risks

Costumes with flammable fabrics, pointed accessories, or masks that reduce vision or make breathing difficult are real risks.

From the clinic: Treating children with falls due to limited vision, asthma crises from dusty or lint-filled fabrics, or minor injuries from sharp objects in costumes.

Tip: Choose safe costumes, without flammable or dangerous elements. Make sure the child can see and breathe properly.

When fear stops being a game

Although fear is part of the game, some children can develop real anxiety, night terrors, or emotional distress from exposure to violent scenes or intense scares.

As a doctor: I have treated cases where the celebration left consequences such as insomnia or phobias in sensitive children.

Recommendation: Respect the child’s emotional limits. Not everyone enjoys horror; observe their reaction and moderate the experience.

Hygiene is also part of the celebration

Among candy, makeup, and going from house to house, many parents forget to wash hands, brush teeth, or clean the skin at the end of the day. This can lead to cavities, skin and eye infections, and other conditions.

What I always recommend:

• Hand washing before eating candy.
• Facial hygiene after removing makeup.
• Extra teeth brushing that day.

• Moderate, don’t ban. Excessive restriction creates anxiety.
• Observe, don’t impose. Not all children enjoy the holiday equally.
• Anticipate, don’t exaggerate. Caring does not mean alarming.
• Educate, don’t scare. Talk to children clearly and calmly.

Halloween can be a safe, fun, and healthy celebration if we stop believing in myths and act with medical judgment. As a healthcare professional, I invite parents, teachers, and caregivers to inform themselves well and protect children through knowledge, not fear.

Happy and healthy Halloween to everyone!
